Institute of Nuclear Medicine and Allied Sciences (INMAS) has established the NMR, PET-Cyclotron facility for enhancing combat efficiency besides providing clinical research to the Armed forces. The institute also pursues a strong research programme with application in various stress-related disorders using NMR techniques including metabolomics, in vivo spectroscopy and functional MRI (fMRI). INMAS has established several non-invasive and innovative nuclear medicine methods. For soldiers working at high altitudes, a method for diagnosis, prevention and treatment of various ailments including cold injuries (frostbite) has been developed. The institute is now working in biological radioprotection (radiation countermeasures); management of thyroid disorders; nuclear and medical imaging; combat casualty management; CBRNe medical management.
