Best PET CT Scan Test by Ganesh Diagnostic Centre in Delhi

1. PET (Positron Emission Tomography) CT (Computed Tomography) Scan

2. The PET CT scan stands for Positron Emission Tomography which is used to detect early signs of cancer, heart diseases as well as rule out any possibility of brain disorders. It is an injectable radioactive tracer which uses advanced technology in order to identify the root cause of the disease cells and is also a combination of PET-CT scan producing 3D images of a more accurate diagnosis. It is a procedure of nuclear medicine that measures the metabolic activities of the cells of the body tissues. It collects the details of the three dimensional images inside of the body. The images show a clear part of the body being investigated and shows which function of the body is working or not. The clearer images can be seen as compared to the CT scan.

3. Ganeshdiagnostic The doctors get to perform the nuclear medicine exams on the outpatients and hospitalized patients who are made to lie down on the exam table. If it is considered necessary, the nurse or the technologist will insert an intravenous (IV) catheter into the vein of your arm or hand. PET scans only use radiotracer injections. It takes about 30-0 minutes to travel through the body and get absorbed in the area under the examination. One will be asked to rest and avoid any kind of talking and movement. It is also advised to drink some contrast material which localizes in the intestines and helps in the radiologist interpreting the examination. One will be moved into the PET/CT scanner in order to begin imaging. One will need to remain still during the imaging. The CT exam takes place first, followed by the PET scan. On one occasion, a second CT scan with intravenous contrast will follow the PET scan. The CT scan takes less than two minutes while the PET scan takes 20-30 minutes. Total scanning time is usually about 30 minutes and depends on which area is under examination, with additional tests involving other tracers or drugs which may be used. For example – if one is examined for heart disease, one may undergo a PET scan both before and after exercising or before and after receiving IV medication which increases blood flow to the heart. If you have an intravenous line for the procedure, your technologist will usually remove it and the technologist will leave it in place if you are to have another procedure the same day.
