World-class technologies. For impeccable care.

Nuclear medical procedures are some of the most commonly performed procedures worldwide.Nuclear Medicine has both diagnostic and as well as therapeutic applications. The division of Nuclear Medicine at MMHRC was commissioned on 12th April 1996 after getting approval from Atomic Energy Regulatory Board (AERB), Mumbai. This division is the first of its kind in southern Tamilnadu and is equipped with state-of-the-art imaging facilities.

Positron emission tomography (PET-CT) is indispensable in the evaluation of oncology patients. It is also utilized in evaluation of myocardial viability and in evaluation of neurological conditions.



Facilities Available:
GE Discovery NM 630 : Dual head gamma camera
GE Discovery IQ 3 ring PET-CT - BGO crystal full ring PET scanner with 16 slice diagnostic CT and Q suite
Equipments required for measurement of radiation and radiation safety equipments are also available.

Services Offered:
Gamma Camera - All diagnostic nuclear medicine techniques are routinely performed in the department.

Renal studies (DTPA, DMSA, EC, DRCG), Skeletal survey (MDP bone scintigraphy), Myocardial perfusion imaging for myocardial ischemia and viability, Lymphoscintigraphy, Endocrine evaluation (Thyroid, Parathyroid) are routinely performed with prior appointments. Serotonin receptor imaging, GI bleed imaging, Meckels scan and special procedures are available at request. The department has performed more than 30,000 nuclear medicine studies since inception.

PET/CT - Oncology PET, Cardiac and neurology PET studies, Fluoride PET for skeletal evaluation are done routinely. PET-CT scans are performed with prior appointment. The department has performed more than 1,800 PET-CT scans since inception.

Radionuclide therapy - Low dose radioiodine therapy for benign thyroid diseases, bone pain palliation are routinely performed. Imaging, treatment advice and follow up thyroid cancer patients are available.

Outpatient services for thyroid diseases and thyroid cancer are available on all working days.
