Nuclear Medicine

The department of nuclear medicine and PET-CT at Aster Medcity is a state-of-the-art facility that offers a wide range of diagnostic and therapeutic nuclear medicine procedures to several specialities including cardiology, neurology and oncology. A highly sophisticated domain in medicine that uses radioactive isotopes for non-invasive imaging and therapeutic procedures, images obtained through nuclear medicine provide functional information at the molecular and cellular level, facilitating accurate diagnosis of diseases in both adults and children. The therapeutic applications of nuclear medicine include advanced procedures like radioIodine therapy of Graves’ disease and bone pain palliation therapy. The department, which is managed by highly trained doctors and technologists, is the first nuclear medicine facility in Kerala to offer a PET- CT machine with Time of flight technology, along with cutting-edge features like Hybrid SPECT-CT gamma camera and dedicated high-dose radioiodine therapy isolation rooms.

Outpatient department functions from 8am to 4.30 pm

Philips Astonish True Flight Select PET-CT With TOF

Equipped with revolutionary Time Of Flight (TOF) technology which increases PET performance, the Philips Astonish True flight select PET CT system operates fully in 3D mode and is exceptionally sensitive for faster scans, which means better lesion detectability, precise anatomical details and minimal PET radiation dose as the FDG dose injected is considerably less.


The GE SPECT-CT OPTIMA NM 640 gamma camera can provide exceptionally clear images at a very high speed, facilitating high-precision diagnosis. Low on radiation dose and examination time, it also allows hybrid by integrating the most advanced general purpose camera with a newly developed four-slice CT.
