Gamma Camera

Gamma Camera

Gamma camera is a nuclear medicine device that provides a detailed diagnosis of the functioning of the thyroid, heart, brain, lungs, liver, gall bladder, and many other parts of the body. It helps determine the severity of or treat a variety of diseases. Gamma camera is also known as scintillation camera.


Gamma camera detects gamma rays emitted by radiopharmaceutical molecules injected into a patient’s body. Once the molecule is fixed on the target organ/tissue, the emitted gamma rays are displayed on a TV monitor. Like an X-ray, the gamma camera produces a two-dimensional projection of a three-dimensional object.

DTPA Renal Scan

A DTPA renal scan is performed to evaluate the functioning of the kidneys. The test involves the intravenous administration of radiopharmaceutical material - Tc-99m DTPA - to find out any site of the blockage. It helps find out the blood supply and flow of urine from the kidneys.

Bone Scan (Whole Body) (99m Tc - MDP)

It is a nuclear medicine test that combines bone scan and SPECT (single photon emission computed tomography) to detect areas of abnormal bone growth due to fractures, tumors, and other bone diseases. A radioactive tracer is injected intravenously and a gamma camera detects gamma radiation to create a planar image of the bones.

Thyroid Scan Tc-99m

The Thyroid Scan Test is shorthand for 99mtc Pertechnetate Thyroid Scintigraphy Test is used to assess the thyroid uptake and scintigraphy using radioactive tracer – 99mTc-pertechnetate. The thyroid uptake is performed to determine the function of the gland.
