General Nuclear Medicine

Nuclear Medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose or treat a variety of diseases, including many types of cancers, heart disease, and certain other abnormalities within the body.

Common Reasons for Nuclear Medicine Scans

  • Analyze kidney function
  • Scan lungs for respiratory and blood clot problems
  • Identify blockage in the gallbladder
  • Evaluate bones for fracture, infection, arthritis, and tumors
  • Determine the presence or spread of cancer
  • Identify bleeding into the bowel
  • Locate the presence of infection
  • Measure thyroid function to detect an overactive or under-active thyroid
  • Investigate abnormalities in the brain

General Nuclear Medicine Procedures

We offer more than 40 procedures within Nuclear Medicine at Danbury Hospital, many of which are not commonly performed at other hospitals in the area.  Procedures we offer include:

Quantitative Tomographic Brain Imaging (SPECT)

SPECT scans are 3D diagnostic tool that let your doctor analyze how your organs are functioning, such as how your blood flows to the brain and metabolism of the brain.

Quantitative Renal Scintigraphy

Quantitative Renal Scintigraphy is a valuable tool in the evaluation of kidney (renal) function. The tracers used have no toxic effects on the kidneys.

Tumor Imaging

Tumor imaging is a diagnostic imaging tool that uses molecular imaging technology to diagnose, manage, and treat many types of cancer, including:

  • Prostascint scanning
  • Octreotide Scan

Tomographic Bone Imaging

Tomographic images allow more detailed imaging of bone abnormalities compared to standard planar images. This is particularly useful with spinal fractures.

Hepatobiliary Imino-Diacetic Acid Scan (HIDA)

Hepatobiliary Imino-Diacetic Acid scanning evaluates the function of the liver to create and excrete bile, and the drainage system (bile ducts) and gallbladder for possible blockage, malfunction, or leak. This will frequently be done together with gallbladder ultrasound for a more complete evaluation.


Lymphoscintigraphy is a type of nuclear medicine imaging that provides pictures of the lymphatic system. It allows surgeons to precisely locate lymph nodes for biopsy.
