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.

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.
