  PET is a procedure that is able to detect small cancerous tumors, and also subtle changes in the brain and heart. This enables physicians to treat these diseases earlier and more accurately than if they waited for the results from other detection modalities. A PET scan puts time on your side! The earlier the diagnosis, the better the chance for successful treatment. click here PET scans offer patients hope. PET can detect disease sooner and the earlier the detection, the more likely the cure! Prior to changes in structure that normally would show up on a CT or MRI scan, a PET scan can reveal metabolic changes in the body. Cancer is a metabolic process and PET is a metabolic imaging technique. PET shows the extent of disease – called staging – of lung cancer, colorectal cancer, melanoma, head and neck cancer, breast cancer, lymphoma and many other cancers. For patients whose cancer is newly diagnosed, it is important to determine if cancer has spread to other parts of the body so ...

  You may be interested in how   PET Scan   work and what the mechanism behind the images we get is. Before the scan, you will be given an injection called a radiopharmaceutical. It attaches to chemicals that are naturally used in the metabolic processes of organs and tissues. Therefore, the cells of your body usually pick up this color. Cancer cells consume more of this color because they are more metabolized than other cells. When cells take up this pigment, PET scans track this radioactive tracer in the body. It works with the help of a scanning device. The PET scanner slowly moves the part of the body or tissue to be examined. When this radioactive tracer breaks down to produce gamma rays, positrons are released. Computer scanners detect these gamma rays and use this information to create image maps of tissues or organs. The amount of radiotracer collected in the tissue determines how bright the tissue looks in the image, which indicates the level of function of the o...

  After completing all essential registration and consent formalities, you would be examined by our doctor. A detailed history of your illness and information relevant to the scan would be noted and all your previous medical records and reports would also be reviewed. You would be then directed to a room where a small dosage of  18  F – FDG / Sodium Fluoride will be injected into your vein. After injection, you would be asked to quietly relax and rest in a separate room at our Center for about an hour before you are taken up for the scan. During this resting period, unless recommended by our staff, no attendants or relatives would be permitted to stay with you in this separate waiting room. You are advised to stay calm, restrict physical movements and avoid talking to others while being present in the room. If in case you are feeling any vomiting sensation or giddiness, inform the staff immediately by pressing the call bell. You may be given oral contrast to drink. You wi...

1. Diagnosing a tumor: A biopsy is a procedure where tissue is removed from any part of the body to find the presence of a disease.  Conducting a biopsy is a delicate procedure and quite often doctors need a CT scan for proper guidance. The doctor will know or confirm if the tumor is present and the details of it- the size and the location. Also, the  CT scan  will reveal and give clarity about how the tumor is connected to the surrounding tissues.  Through CT scan the surgeon ensures that the surgery is conducted successfully and he/she knows what to expect when surgery becomes imperative to remove the tumor.  2. Examining blood tissues: When there is a blockage that needs to be checked or some other health challenge, a CT scan helps the doctor to examine blood vessels without the need to perform surgery to examine them. CT scan in such a case becomes vital to diagnose and decide the treatment for vascular diseases.  3. Examine body parts with small bones:...

  A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs. The   PET   scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity. A   PET   scan can often detect the atypical metabolism of the tracer in diseases before the disease shows up on other imaging tests, such as computerized tomography (CT) and magnetic resonance imaging (MRI). The tracer is most often injected into a vein within your hand or arm. The tracer will then collect into areas of your body that have higher levels of metabolic or biochemical activity. This often pinpoints the location of the disease. The  PET  images are typically combined with  CT  or  MRI  and are called  PET-CT  or  PET-MRI  scans.
