Computed Tomography for Dental Implantation

Installing an implant requires thorough preparation. The operation is preceded by the collection and analysis of data on the state of health of the patient, the anatomical features of his oral cavity. The doctor assesses the results of the best CT scan in Delhi, a detailed image of the bones and soft tissues of the maxillofacial region obtained by computed tomography. Based on complex data, it is possible to make a prediction of implant implantation.

The method of computed tomography of the jaw is actively used in implantology. It is necessary if the panoramic picture does not give a complete picture of the features of the bones and tissues that the implantologist will deal with. The X-ray emitter rotates along the path of the helix; it can scan bone tissue, temporomandibular joint, dental roots - depending on the nature of the doctor's prescription.

A cone beam Tomograph creates a digital model of the patient’s maxillary system in 3-D format. Thus, the features of the teeth, the thickness, density and structure of the jaw bone tissue, the position of the maxillary sinuses are determined with precision. The specialist models the implantable implant calculates its inclination and the position of the jaw. The whole procedure of integrating the artificial root depends on the quality of the examination.

Also, with the help of CT, the state of filling materials in the teeth, roots, dentin, pulp, and nerve tissue is assessed. During the examination, it is possible to identify the formations at an early stage and begin their treatment.

Key advantages of using CT scanner in dentistry:

A copy of the picture is saved to external media or printed. The patient will also be able to see how his teeth will look after correcting the problem.

The method of 3D tomography is used in medical dentistry. Using a snapshot, the specialist determines the treatment method and the Osseo integration scheme. A special program allows you to test the result of implantation and eliminate complications.

How is CT performed?

A computer and a scanning device are integral parts of a dental 3D tomography. The scanner is provided with X-rays. There are two types of equipment:

The scanner is in the shape of a cylinder, in which the patient lies.

A special unit for dental offices. It has a rotating part and support for the patient's head.

Both types of scanners at CT scan Centersare programmed to take up to six images per second. All data is transferred to the computer for processing. Special software reproduces on the screen a model of the scanned area. The 3D image consists of several layers. Pictures are displayed on the monitor screen. The specialist analyzes the three layers of the scanned area: frontal, diametrical, vertical.

For security reasons and to obtain a high-quality snapshot, the client needs to perform a number of actions:

  •        Get rid of metal objects (remove earrings, chains, etc., jewelry);
  •        Wear a radiation protective apron;
  •        Sit down or lie down, fixing the head on the support;
  •        Do not move while scanning the jaw, forming a 3D image.
  •        If there is a need to introduce a contrast agent, the patient should not eat and drink 4 hours before the session.

 

 

PET, A Test Increasingly Requested in Oncology But Limited by Its High Price

If you have been treated for cancer, it is normal that you want to do everything possible to ensure that you do not return. But you may not need the tests, and your risks may be greater than the benefits. Below is the reason:

In general, PET-CT scans do not help people who have completed cancer treatments and have no symptoms.

For most cancers, these tests do not help you live longer or have a better quality of life. If you have the tomographies done without a good reason, they can produce anxiety, wrong diagnoses, false alarms, unnecessary procedures, and more costs.

Often, there are better ways to monitor your condition:

  •         It is alert to symptoms that could mean that cancer has returned.
  •         Get regular exams that include a medical history and a medical exam.
  •         For some cancers, there are simple tests you should do, such as mammograms for women who have been treated for breast cancer.
  •         Ask your doctor what proof, if any, is appropriate for your situation.

PET and PET-CT scans have risks.

Performing whole body PET scans Delhi can contribute to stress as a cancer survivor. Often, these tests detect medical problems that are not serious. This could cause more tests and procedures, including follow-up scans, and even biopsies and surgery.

In addition, PET scans, and especially PET-CT scans expose you to high levels of radiation. The effects of radiation accumulate throughout your life. This can increase your risk of cancer. They should not do multiple CT scans unless there is medical evidence that shows they would help you. Ask your consulted doctor if it is a good idea to have multiple CT scans.

So, when is a good idea to have a PET scan after treatment?

A PET scan or PET-CT scan may be helpful if your doctor suspects that your cancer has returned, based on your symptoms, a medical exam or other tests. A CT scan may also be suggested if you were given treatment for advanced cancer, and your doctor needs to find out if your most recent treatment was effective.

Positron emission tomography (known as PET, according to the acronym in English) is the newest of these non-invasive diagnostic techniques introduced within the field of nuclear medicine. PET brings together the most advanced physics, electronics, and computer engineering, disciplines on which it has depended for its development and implementation in clinical practice. But its use is being held back by the high price of the test.

The latest generation scanners of PET CT scan are not claustrophobic for the patient and allow obtaining high-quality full body images in a reasonable time of 30 to 60 minutes. The PET obtains images of the whole organism thanks to the action of diverse molecules marked with isotopes (radioactive drugs) emitting positrons (subatomic particles), which have been previously injected to the patient by the intravenous route.

 

When Do I Need to Undergo PET CT Scan ?

Computed tomography occupies a leading position in the field of visualization diagnostics. Using this method, you can select the contours, shape, and position of the tumor in the body. Positron emission tomography (PET) provides information on the metabolic activity of the tumor, in many cases accurately detect the tissue affected by cancer and confirm the effectiveness of chemotherapy.

These two processes are combined in a unique method of accurate diagnosis and tumor localization. PEC-CT can act as a tool for deciding whether surgery or chemotherapy is necessary. Using this method, you can accurately determine the size, position, activity, and area of spread of neoplastic disease. It combines the advantages of two different technologies in one device.

Benefits of PET-CT

In one session of the survey, you can determine the presence of metastases in the human body.

Immediately after the start of chemotherapy, you can determine its effectiveness. If sugar consumption in the area of cancer or metastasis is reduced, then cancer treatment is effective. If sugar consumption remains high, then it is possible at the initial stage to switch to other methods of treatment and thereby increase the chances of cure.

In the course of subsequent treatment, this diagnostic method allows to determine the possible residues of a tumor or the formation of new metastases or to exclude their presence.

You will receive an accurate diagnosis in time for an early stage of the disease. This is very important because the timely start of treatment is crucial for the treatment of cancer.

When do I need to undergo PET?

The PET CT scan method is used primarily in the diagnosis of cancer, such as cancer of the esophagus, lung or thyroid, head, and neck, including malignant lymphadenopathy (malignant lymphomas). With the help of PET-CT is determined by the focus of cancer lesions. Also, the examination reveals the degree of malignancy of the tumor and the stage of the disease. This is very important for the selection of a suitable treatment method, including the elimination of unnecessary therapeutic measures.

During or immediately after the end of treatment against cancer, the PET-CT method allows to evaluate the effectiveness of the treatment. Also, PET is used to diagnose diseases of the heart and nervous system. The areas of application include, above all, the definition or exclusion of stitches before heart bypass surgery, as well as in dementia.

How is the examination?

For the examination, a small amount of a short-lived radioactive drug is administered to the patient. The patient lies comfortably on his back, if possible not moving. The medical couch gradually passes through a rather wide opening in the apparatus. The PET scanner is silent. The examination is performed using a PET scanner, which visually resembles a Computed Tomography (CT).

That is, it is not a narrow tunnel as in magnetic resonance imaging (MRI). During the examination, the PET CT scan camera takes phased shots of the entire body. A computer connected to the camera analyzes the received data and outputs a complex image. It shows how the radioactive substance has spread throughout the body.

The examination time is from 20 to 45 minutes. After that, the obtained images are reconstructed on a computer to obtain the final result of the analysis. Sometimes, for a better examination of the epigastric region, an antispasmodic is introduced into the body to suspend the active activity of the colon.

Kidney Cancer and CT Scan- Know the Connection

Kidney cancer, also known as adenocarcinoma or renal cell carcinoma, hypernephroma or renal cancer, is twice as frequent in men as in women, and as specified in the latest report. Kidney cancer is twice as common in men as in women and CT is usually the best method for its detection

For its efficient detection, the Computed Tomography (CT) is generally the best method (as well as it is to detect tumors of the lung, liver or pancreas, among others), since the image provided by this imaging technique allows the doctor to confirm the presence of a tumor, measure its size, identify its exact location and at the same time determine the extent it has on other nearby tissues.

Also, the CAT can be used not only to detect cancer in the kidneys, but to detect if they suffer the following:

  •          Tumors or other injuries.
  •          Obstructions such as kidney stones.
  •          Abscesses (infection and inflammation of the tissue of the organism characterized by swelling and pus accumulation).
  •          Polycystic kidney disease.
  •          Birth defects.

How to prevent kidney cancer?

There are some guidelines you can follow to prevent kidney cancer, such as:

  •          Do not smoke, since tobacco represents a high percentage of cases of kidney cancer.
  •          Eating a balanced diet: obesity and high blood pressure are also risk factors for kidney cancer.
  •          Avoid exposure in the workplace to harmful substances such as cadmium and organic solvents.
  •          It is advisable to perform an abdominal ultrasound every four or five years after age 40 in those cases with a family history of this type of cancer.

What are the risks in a CT Scan Cost of the kidneys?

If you see yourself identified with some of the following situations, it is essential that you notify the professional to avoid risks and proceed with the diagnosis through other techniques:

If you regularly take certain medications for diabetes, you may be at risk of developing metabolic acidosis (one of the acid-base balance disorders).

People with kidney disease are more likely to have kidney damage after exposure to contrast dye from a CT scan.

If you are allergic or sensitive to medications, contrast dyes, local anesthesia, iodine or latex, let them know before performing a CT scan.

In pregnant patients, radiation from CT can cause risks and negative effects on the fetus.

How is computed tomography used in oncology? 

CT is used in oncology in many different ways:

  •          To detect growth abnormal of tissue
  •          To help diagnose the presence of a tumor
  •          To get information about the stage of a cancer
  •          To determine exactly where to perform (ie, guide) a biopsy procedure
  •          To guide some local treatments, such as cryotherapy, radiofrequency ablation and the implantation of radioactive seeds
  •          To help plan external beam radiotherapy or surgery
  •          To determine if a cancer reacts to treatment
  •          To detect the return (recurrence) of a tumor

The CT scan is painless. However, staying on the table in one position during the procedure can be a bit uncomfortable. The duration of a CT procedure depends on the size of the body area being scanned, but in general it only lasts from a few minutes to a half hour. For most people, CT is given on an outpatient basis in an CT scan Lab, without staying in the hospital at night.

Computed Tomography Of The Lungs

Computed tomography of the lungs is a method of X-ray examination, which is based on the reproduction of images obtained by circular scanning of the object by a directed beam of X-rays. In the study of lungs, CT provides an opportunity to determine the location of interlobar gaps, intersegmental septa clearly, and assess the state of bronchi and pulmonary vessels. Computerized tomography of the lungs is the fastest and most accurate method of diagnosing diseases in this area.

The Primary Indications for the CT Scan Cost in Delhi NCR Are:

  •        Pleurisy
  •        Tumor Education
  •        Metastasis of tumors
  •        Parasitic cysts of the lungs
  •        Lung disorders caused by rheumatoid diseases
  •        Abscesses
  •        Suspicion of pulmonary arterial thromboembolism
  •        Tuberculosis

Computer tomography of the lung can be performed on a conventional tomography or spiral. Traditional CT of the lung is performed to visualize pathological processes in the lungs. The study time is approximately 20 minutes. During the scan, the patient must repeatedly hold his breath. CT of the lungs, carried out on a spiral tomograph lasts only about 15 seconds and it is necessary to delay breathing only once. This method makes it possible to evaluate the state of the lymph nodes of the mediastinal organs as well.

No preliminary preparation is necessary before carrying out a computed tomography of the lungs to the patient. The only exception is when the CT scan cost in Delhi is performed with contrast. In this case, it is recommended to refrain from eating for 5-6 hours before the study, as when injecting a contrast agent, a feeling of nausea may appear.

Contrast substance helps to visualize soft tissues and blood vessels better. During the study, the patient is on the movable table of the apparatus, which moves inside the tunnel, and at this time a tomography ring rotates around it. After the end of the procedure, the patient expects results.

The doctor concludes within 10-15 minutes, then all the data (pictures and their description) are given to the patient's hands or sent by e-mail to the treating doctor. Depending on the type of pathology detected, the treatment can be prescribed by doctors: an oncologist, a surgeon, or a pulmonologist.

HOW TO SCAN?

The specialist helps the patient to take the correct position on the computer tomography table. It is possible to use soft straps or ribbons to help keep the neck in the right place.

During the scan, the patient will be inside the computer tomograph. Many X-rays will pass through the patient's body when the X-ray tube rotates around it. The machine will take pictures from many sides, forming transverse images (slices) of the neck.

The technologist leaves the room. During the scan, the patient will be alone in the place, but the technologist can always see, hear and talk with him through the intercom.

For the first few checks, the table quickly moves through the scanner. The schedule will proceed slower for the rest of the scan. Neck scanning can take up to 15 minutes. Then the doctor looks at the pictures on the computer.

Some patients need a contrast study. Patients will receive a contrast (X-ray dye) during the scan. The difference makes the tissues and blood vessels more visible to the doctor's view to see them in CT images.
