NMT is a technique that involves the use of radioactive materials namely, radiopharmaceuticals. It is useful in analysing biological specimens, to obtain images of organs, treat disease and study body functions. The technique is a safe and effective way to use radionuclides to obtain results through diagnostic imaging and therapeutics. The process involves injecting the radiopharmaceuticals to patients or administering the same orally or by inhalation.
Nuclear medicine technologists play a vital role in the health care team. With the addition of new technologies like hybrid imaging combined with nuclear medicine and other advanced techniques, the field of NMT has grown leaps and bounds.
PET stands for positron emission tomography, which is an imaging test that enables your doctor to check for disease in your body. The process involves injecting of a special dye that has radioactive tracers, into a vein in your arm. Next, the tracers are absorbed by your organs and tissues and the PET scanner can now detect them. This in turn helps the doctor to assess the functioning of your organs and tissues. The test is efficient, in the sense that you can carry on with your routine chores after it’s finished.
This technique is commonly used to detect cancer, heart problems, brain disorders and problems with the central nervous system. PET also helps your doctor easily detect complex systemic disease such as brain tumours, coronary artery disease, memory disorders and seizures. Just like a few other procedures, this scan also requires a patient to be prepared in advance as per the doctor’s instructions.
