PET-CT Division

PET-CT and Cyclotron
NINMAS is running a state-of-art PET-CT service providing scans for patients with malignancy, inflammatory and infectious diseases and neurological disorders. PET-CT has been established recently in 2015 at NINMAS under the Ministry of Science and Technology (MOST) through an ADP project, “Establishment of Positron Emission Tomography-Computed Tomography (PET-CT) with Cyclotron facilities”. Installation of Cyclotron is under process. The most popular PET tracer 18F- fluorodeoxyglucose(FDG) is being produced by cyclotron and is being procured from the only Cyclotron center (privately owned) of the country.

PET- CT is an innovative nuclear medicine diagnostic technique combining functional and anatomical information. Radiation from a tracer is detected by a ring of detectors (PET: functional information) and fused with anatomical information from the CT. The most widely used tracer is fluorodeoxyglucose (FDG). It is an analogue of sugar and is taken up by cancer cells and inflammation. We work closely with the referring clinicians and provide a fast turnaround high quality service. We offer scans with FDG for patients with malignancy (lung, lymphoma, colorectal and others), inflammatory and infectious conditions (pyrexia of unknown origin, tuberculosis, large vessel vasculitis, infection) and neurological disorders (memory loss, cognitive impairment and dementia).

Plans have been taken to initiate FDG Cardiac PET Scan (for assessing myocardial viability). After establishment of in-house Cyclotron, 13N, 15O, 11C and other short half-lived isotope studies would be possible. Starting from the very first day PET-CT studies, quite a good number of patients have been benefited and resulted in reduction of numbers of patients going abroad for advanced medical management.

PET-CT Studies at NINMAS
 • Whole Body FDG PET-CT Scan (For Cancer, Infection, Fever of Unknown Origin, Occult  Malignancy)
 • FDG Brain PET (for Dementia, Epilepsy, Neuro-rehabilitation)
PET-CT studies are conducted through appointments of patients. Leaflets containing detailed information regarding the preparation of the studies and procedure are provided to the patients in these sessions, prior the tests.
PET-CT Imaging Procedure
For PET-CT imaging an IV channel is opened in patient’s hand to give FDG injection. After injection patient has to wait for 45-60 minutes. During this period patient has to take rest in lying condition closing his eyes and rest his voice also (talking is not allowed). Scanning time in machine bed is 20-25 minutes. Patient may need to stay total 4-5 hours at NINMAS to complete the procedures and waiting due to queue.
