Cancer and PET CT Scan

Everyone who has suffered from cancer knows the importance of early diagnosis and effective treatment. However, the situation in the country is absurd: there is not enough money for medicine, and modern treatment with effective medicines is paid for by the patient or depends on the availability of public donations, therefore high-tech diagnostics are mostly available in private medical institutions.

PET / CT allows you to assess the extent of the tumor lesion of the patient and correctly determine the stage of the disease. Information on how far malignant cells have spread is extremely important for the choice of treatment tactics. Examination of patients undergoing radiotherapy and chemotherapy, or undergoing surgery, is necessary to monitor the results of prescribed treatment - PET / CT scan will show how the tumor changes, will allow to see new foci and relapses.

A full-body PET / CT scan is performed for:

  • Detection of metastases and primary tumor foci;
  • Determine the extent of the tumor process;
  • Evaluation of the effectiveness of treatment;
  • Differentiation of benign and malignant tumors;
  • Planning tactics of therapy.

In PET-Technology, diagnostics with 18-FDG is carried out for the following diseases: malignant skeletal tumors, melanoma, Hodgkin's disease and non-Hodgkin's lymphomas, soft tissue sarcomas, thyroid cancer, breast, cervix, thymus, testicles, lung glands, ovaries, stomach and intestines.

The test scan takes place in two stages:

The introduction of the drug. The patient is given an intravenous injection. The procedure is painless, sometimes accompanied by a sensation of heat. The drug is distributed in all cells within an hour. Important: After the introduction of the drug you need to lie quietly, do not move, do not talk, do not read - 18-FDG accumulates in actively working muscles, which can affect the results. Drink clean water to improve cell imaging.

PET/CT scan. The patient is placed in a tomograph, where a computed tomography of the whole body is first performed, followed by a positron emission tomography of the whole body. In some cases, a contrast agent is additionally introduced, which improves the visualization of the hollow organs - the intestines and vessels. The software of the device superimposes CT scans on PET scans, as a result, structural, physiological and metabolic changes in the tissues can be assessed.

PET / CT does not last more than an hour, but in the center you will spend from 2 to 5 hours - this includes preliminary preparation, documentation, and rest after the procedure. Before the examination, you need to change into comfortable clothes and remove all products containing metal.

During the rest period it is important to maintain immobility, this contributes to the correct distribution of the radiopharmaceutical and, as a result, to a qualitative display of the pathological focus. To obtain a good quality of the study, it is necessary to remain stationary during the entire scan time (the study can last from 20 to 40 minutes).

After completing the procedures, do not leave the territory of the diagnostic lab in Delhi without the permission of the medical staff, as it may sometimes be necessary to repeat the scan.

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.

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.
