Nuclear technology is usually perceived as something associated with destructive weapons or power generation. What is not that known is that it has tremendous potential in the field of medicine. To put it in a simple fashion, it is a medical speciality that deals with the application of radioactive substances in the treatment of diseases.
What is nuclear medicine?
Nuclear medicine, medical specialty that involves the use of radioactive isotopes in the diagnosis and treatment of disease. Nuclear medicine began only after the discovery by Enrico Fermi in 1935 that stable elements could be made radioactive by bombarding them with neutrons. The atoms of the elements so bombarded capture these neutrons, thus assuming a different nuclear form while remaining the same elements. These radioisotopes have unstable nuclei, however, and dissipate excess energy by emitting radiation in the form of gamma and other rays.
In isotope scanning, a radioisotope is introduced into the body, usually by means of intravenous injection. The isotope is then taken up in different amounts by different organs. Its distribution can be determined by recording the radiation it emits, and through charting its concentration it is often possible to recognize the presence, size, and shape of various abnormalities in body organs. The radiation emitted is detected by a scintillation counter, which is moved back and forth over the organ being scanned; these messages can then be electronically recorded and studied by clinicians. The radioisotope usually has a short half-life and thus decays completely before its radioactivity can cause any damage to the patient’s body.
Different isotopes tend to concentrate in particular organs: for example, iodine-131 settles in the thyroid gland and can reveal a variety of defects in thyroid functioning. Another isotope, carbon-14, is useful in studying abnormalities of metabolism that underlie diabetes, gout, anemia, and acromegaly. Various scanning devices and techniques have been developed, including tomography and magnetic resonance imaging.

The emergence of complex ailments has created a huge demand for professionals in this field. “This discipline is fast experiencing growth in India due to its immense potential and contribution in the fields of cancer, cardiology and neurology. Currently India has 234 nuclear medicine centres and 20-30 new nuclear medicine facilities are added every year. Due to its rapid growth in last decade, there is shortage of trained manpower in the field,” says Dr. Anshu Rajnish Sharma, President, Society of Nuclear Medicine India, the body of nuclear medicine and molecular imaging professionals in India.

Many universities offer a BSc or MSc degree in nuclear medicine, while many medical colleges offer an MD in the subject. About 40 medical professionals are awarded with MD/DNB degrees in nuclear medicine every year across various centres of learning.
For admission to the BSc programme, the candidate must have scored at least 50% marks at 10+2 level with Physics and Chemistry as compulsory subjects and Biology or Mathematics as optional subjects. For MSc, candidates must have a BSc degree in Nuclear Medicine or Medical Imaging Technology. MBBS qualified candidates can apply for MD in nuclear medicine.
The curriculum for BSc students includes human anatomy and physiology, radiochemistry and radio pharmacy, medical ethics and computer applications. Postgraduate students pursuing MSc and MD degrees study nuclear physics, image processing techniques, statistical tools on nuclear medicine and high end computing related to nuclear medicine. Rigorous laboratory work and dissertations are compulsory for students. Students also have to pursue internships for hands-on experience towards the end of their courses.
Selected institutions offering courses in Nuclear Medicine
Tata Memorial Hospital, Mumbai
Radiation Medicine Center, Mumbai
Christian Medical College, Vellore
Amrita Institute of Medical Sciences, Kochi
Ram Manohar Lohia Hospital, Delhi
Kovai Medical Center & Hospital, Coimbatore
After completing a degree in nuclear medicine one has the option of working with government and private sector hospitals. “After doing BSc/MSc, candidates get the job of Nuclear Medicine Technical Officer or Medical Physicist in Department of Nuclear Medicine at various government or private hospitals or Diagnostic Centres in the country. These courses are approved by Atomic Energy Regulatory Board. Their job profile is to prepare Radiopharmaceuticals and operate on high end scanners like SPECT-CT, PET/CT and PET-MRI for acquiring images of patients. The remuneration of Nuclear Medicine Technologist may range from Rs.30000-40000 per month in government institutes,” adds Dr Sharma.
There is a massive requirement of nuclear medicine professionals in the industry. “With an exponential rise in the numbers of SPECT gamma cameras and PET scanners in recent years, there has been a visible presence of this speciality in the medical practice. Currently, for the functional evaluation of various organs like kidneys, and heart; and for the diagnosis and assessment of various cancers, a vital role is played by nuclear medicine. But, the availability of this service is far less than the demand,” states Dr Regi Oommen, the Head of Department of Nuclear Medicine at Vellore's Christian Medical College.

Professionals generally opt for corporate jobs or for academic careers. “I completed my BSc in Nuclear Medicine and Technology from Manipal University in 2009. After completing my DNMT and MSc degrees, I opted for an academic career. In the near future, I plan to pursue PhD in nuclear medicine,” says Ramandeep Bhalla, Assistant Professor, Department of Nuclear Medicine, School of Allied Health Sciences, Manipal University.
Research: The prospects and challenges
As nuclear medicine evolves, there is a huge room for research in this field. “At present, India lag behinds many western countries in nuclear medicine as the equipment required are very expensive and these are mainly available in tertiary care hospitals. However, it is expected that these would reach to more health centres. The R&D in the field can be given boost if the Govt. of India invests more in the field by providing special grants to departments involved in research in developing novel radiopharmaceuticals as it is very expensive and academic institutions cannot procure them out of their own resources,” says Dr Rajat Sandhir, Head of the Department, Centre for Nuclear Medicine, Panjab University.
