Functional imaging is possible only with PET camera, says RMC head Dr Narendran Nair. It studies body functions almost true to nature, he says. PET imaging is very accurate in differentiating malignant from benign growths, as well as showing the spread of malignant tumours. PET imaging can help detect recurrent brain tumours and tumours of the lung, colon, breast, lymph nodes, skin, and other organs. Information from PET imaging can be used to determine what combination of treatment is most likely to be successful in managing a patient's tumour.
PET imaging can provide information to pinpoint and evaluate diseases of the brain.
PET imaging can show the region of the brain that is causing a patient's seizures and is useful in evaluating degenerative brain diseases such as Alzheimer's, Huntington's, and Parkinson's. Within the first few hours of a stroke, PET imaging may be useful in determining treatment therapies. PET is an imaging technique that is used to visualize some of these processes that change. Even in diseases, such as Alzheimer's disease, where there is no gross structural abnormality, PET is able to show a biochemical change. PET is a very useful addition to the clinician's diagnostic toolbox, providing significant advances to traditional diagnostic methods.
