Any other relevant particulars

  • In a nuclear medicine test, small amounts of radiopharmaceuticals are introduced into the body by injection, swallowing, or inhalation.
  • Radiopharmaceuticals are substances that are attracted to specific organs, bones, or tissues.

  • The amount of radiopharmaceutical used is carefully selected to provide the least amount of radiation exposure to the patient but ensure an accurate test

    Nuclear Medicine studies involve the use of small amount of radioactive isotopes administered into the body.

    It is mainly used to detect the spread of cancer to the bones especially in cancer of breast, prostate, thyroid & lung.

    The functions of organs like kidney, liver and brain are also being studied by the isotopes.

    We also use similar isotopes for studying the function of thyroid gland.

    Radioactive iodine is used to detect the spread of cancer into other organs.

    We also use such isotopes for the treatment of the similar spread to other organs.

    Advantages Of Nuclear Medicine

    Cost effective.

  • Nearly 100 different imaging procedures are available today

  • Provides information about the function of virtually every major organ system.

  • The safest diagnostic imaging tests available.

  • The amount of radiation in a nuclear medicine procedure is comparable to that received during a diagnostic x-ray.

  • Children can commonly undergo nuclear medicine.

  • Nuclear medicine procedures are painless and do not require anesthesia.

  • Nuclear medicine is practiced only by

  • Licensed physicians

  • Certified technologists

  • Physicists

  • Radiation safety officers and Pharmacists.

  • Nuclear medicine combines chemistry, physics, mathematics, computer technology, and medicine in using radioactivity to diagnose and treat disease.

  • Nuclear imaging detects functional (vs. anatomical) properties of the human tissue.

  • The imaging is done by tracing the distribution of radiopharmaceuticals within the body with a suitable instruments.

  • The various types of NM images can be classified as

  • Static planar scintigraphy

  • Dynamic planar scintigraphy

  • Whole-body scintigraphy

  • Single photon emission computerized tomography

  • Multi gated acquisition

  • Radiation safety

  • Although we don't think much about radiation, everyone is continually exposed to radiation from natural and manmade sources.

  • Most nuclear medicine procedures expose patients to about the same amount of radiation as they receive in a few months of normal living.


    CMEs are conducted by the department. Invited speakers from reputed institutions in the country and from abroad participate.
