PET-CT Facility
The Department of Nuclear Medicine is equipped with the state-of-the-art 8 slice PET-CT scanner (Positron Emission Tomography - Computed Tomography), the first of its kind in the state of Kerala. It provides superior diagnostic information for patients with cancer, ischemic heart disease and certain neurologic conditions. In the three decades since its development, PET has been demonstrated to be a clinically proven and safe method for imaging a variety of disorders. The advantages of PET have been augmented by the addition of CT in the same gantry providing combined imaging in one sitting. PET-CT is a whole-body imaging procedure, is cost-effective and is used in the staging, and follow-up for most cancers, including lymphomas, lung, colorectal, gynaecological, head, neck and breast cancers. It is also used to evaluate treatment response after chemotherapy and radiotherapy. Mid cycle PET-CT is useful to ascertain if the patient is responding to chemotherapy, so that regimes can be modified. It is also used in Radiotherapy planning. PET is able to discover these changes in their earliest stages, often before any symptoms appear. With this information on early developing cancers, effective treatment plans can be initiated sooner. PET can sometimes eliminate the need for other invasive procedures and by correctly staging cancers, may prevent unnecessary surgical procedures.
Gamma Camera Facility
Nuclear Medicine imaging or Scintigraphy utilizes a dual head gamma camera to record the physiological activity of selected organs or body systems. This imaging is fundamentally different from magnetic resonance imaging (MRI) and computed tomography (CT), for these methods only convey anatomic information. In most diseases, physiological changes precede anatomic changes, so scintigraphic evidence of a disease process can be diagnosed at an earlier stage. On the other hand, the MRI and CT are useful for clinical diagnosis after the disease process causes significant anatomic alterations. The gamma camera images the gamma rays emitting from the patient who has been injected with minute quantities of a radioactive tracer bonded to various test specific pharmaceuticals.
