DNB (Nuclear Medicine)
Dr Sudatta Ray, has graduated from the prestigious Madras Medical College and Rajiv Gandhi Goverment General Hospital Chennai from the The Tamil Nadu Dr MGR Medical University, Chennai in 2010, one of the largest and oldest medical colleges in the country. He completed his post graduation DNB Nuclear Medicine from Narayana Hrudyalaya Hospitals, Bangalore in 2015 with special expertise in nuclear cardiology. He is certified radiation safety officer (RSO II) from Atomic energy regulatory board (AERB), Mumbai, Govt of India.
He worked as Consultant Nuclear Medicine at Utkal Hospital Bhubaneswar from 2015, the first nuclear medicine facility in the state which was the only PET CT centre for Odisha and few neighbouring states. He was instrumental in starting the first high dose radioiodine treatment facility for thyroid cancer in the state in 2016.
Advanced cancer imaging with Gallium 68 PSMA and Gallium 68 DOTANOC PET CT was started under his guidance for the first time in Odisha which enabled patients to avail modern technology based healthcare facilities near home. Advanced Lutetium PRRT therapy was started in 2019 in Bhubaneswar by him which is only available in handful of premier institutes in the country.
Now he is Consultant and Head of Department of Nuclear Medicine and PET CT at SUM ULTIMATE MEDICARE, Shiksha O Anusandhan University, Bhubaneswar which is multispecialty corporate hospital with dedicated comprehensive cancer care facility.
Nuclear medicine imaging provides functional information about pathological conditions helping to delineate accurate clinical condition. It deals with careful and expert utilization of medically approved radioactive isotopes for molecular imaging and therapy.
Evaluation of thyroid disease such as hyperthyroidism and thyroid cancer has been traditionally in the domain of nuclear medicine. However with advent of cutting edge technology and development of molecular biology, it is now possible to use radioactive isotopes to elicit functional information via various mechanisms at the molecular level. This has been particularly useful in field of oncology where PET CT scan has revolutionized the approach towards cancer imaging. FDG PET CT utilizes cellular glucose metabolism to identify, stage and prognosticate cancer.
Similarly PET based GA 68 imaging of prostate cancer and neuroendocrine tumors have provided simpler and accurate disease evaluation and facilitated proper monitoring and therapeutic intervention.
Nuclear medicine imaging is also useful in evaluation of kidney function by DTPA renograms and assessment of renal scarring by DMSA renograms. Myocardial perfusion imaging using 99mTc Sestamibi is extremely informative and noninvasive mechanism to evaluate coronary blood flow in patients with CAD. Along with FDG PET cardiac viability study, nuclear imaging of the heart provides crucial evidence regarding decision making for myocardial revascularization.
Nuclear medicine therapy using radioiodine has remained a mainstay in treatment of thyroid cancer and hyperthyroidism. Novel therapeutic isotopes like 153 Samarium, 177 Lutetium are now available for use in our country for cancer treatment.
Nuclear medicine is one of the most useful peaceful application of nuclear sciences helping millions of people worldwide.
