One Step Ahead

Helping You Achieve Success

IASNM provides a platform for Nuclear Medicine Professionals in India, USA and elsewhere to connect and collaborate. Originally conceived to promote and share knowledge of Nuclear Medicine to India through Nuclear Medicine Professionals of India origin in the US, IASNMs focus has evolved with changing times from sharing to networking and collaboration; a testimony to the significant strides India has made in the field of Nuclear Medicine.

Connect Nuclear Medicine Professionals of Indian origin (physicians, scientists, radiochemists, technologists and others) in US, India and across the world



IASNM was conceived in 1979 and incorporated as a non-profit tax-exempt organization in the State of Texas in 1984.



Members are primarily physicians, scientists, and technologists in nuclear medicine, with professionals from other fields also welcome.



Advance nuclear medicine through knowledge exchange among members and promote state-of-the-art practices in developing countries, especially India.

What is Nuclear Medicine & Molecular Imaging?

Molecular imaging is a type of medical imaging that provides detailed pictures of what is happening inside the body at the molecular and cellular level.

Nuclear Medicine is a branch of medicine that uses radioactivity for diagnosis and therapy. It started in the mid-1920s when German scientists experimented with radionuclides on rats.

Tracers (pharmaceuticals labelled with radiation emitting isotopes or radionuclides) are administered to patients (either intravenous, orally, inhalation, subcutaneously/subdermally) and the radiation emitted is detected by scintillation cameras (gamma cameras or PET cameras) and images are produced from this, depicting the distribution of the tracer within the body.

Radiopharmaceuticals are administered (usually intravenously) to treat disease with curative or palliative intent. They act by killing abnormal cells within the body by high but localized radiation exposure (akin to targeted internal radiation).

PET/CT, a hybrid imaging technique, combines functional/physiologic imaging with the more traditional anatomic/structural imaging. By providing the best of both worlds, it has played a pivotal role in ushering in the new era of Molecular Imaging, to go hand in hand with Molecular Medicine in the 21st century.
