Molecular/Nuclear Radiology

Molecular imaging, also called Nuclear Medicine, uses small amounts of radioactive materials, or tracers, to examine organ function and structure. It is often used to help monitor, diagnose and treat abnormalities very early in the progression of a disease. Molecular imaging studies examine organ function and structure, whereas diagnostic radiology is based primarily on anatomy. It is a combination of several disciplines, including chemistry, physics, mathematics, computer technology and medicine.

Our Expertise


Molecular imaging studies assist the radiologist in diagnosing diseases. Tumors, infection and other disorders can be detected by evaluating organ function. The nuclear medicine camera takes pictures to show how and where the tracers travel through your body and measures the amount of tracer absorbed. These images show the function, size and shape of an organ, tissue, bone or body system.

The diagnostic capabilities of molecular imaging include:

  • Analyzing kidney function
  • Image perfusion and function of the heart & localizing ischemia and infarction
  • Screening lungs for respiratory and perfusion problems
  • Evaluating gallbladder and liver function
  • Evaluating bones for fracture, infection, arthritis or tumor
  • Determining the presence or spread of cancers
  • Identifying bleeding into the bowels
  • Locating the presence of infection
  • Evaluating thyroid function and thyroid nodules
  • Cardiac viability in advanced coronary artery disease

Molecular Imaging Procedures


Bone Scan

Used to detect arthritis, neoplasm, fractures and sports injuries, tumors and metastatic disease, as well as unexplained bone pain.

Procedure Prep

Gastric Emptying

A gastric emptying study is performed to evaluate the function of the stomach by measuring how quickly food empties from it.

Procedure Prep

Hepatobiliary Scan

Also called a gallbladder or HIDA scan, it is used to evaluate upper abdominal pain, find causes of jaundice and identify gallbladder obstruction.

Procedure Prep

MUGA

Uses a tracer and a special camera to take pictures of your heart as it pumps blood to measure how well it pumps with every heartbeat.

Procedure Prep

Parathyroid Scan

Used to detect abnormalities within the parathyroid glands, which regulate the amount of calcium in your body.

Procedure Prep

Renal Scan

Uses a small amount of radioactive material (radioisotope) to measure the function of the kidneys.

Procedure Prep

Thyroid Whole Body Scan

Used to discover residual tissue after the thyroid has been removed or if abnormal thyroid tissue exists in other areas of the body.

Procedure Prep

Thyroid Uptake and Scan

Provides information about the thyroid and determines if the gland is working properly and can detect abnormalities.

Nuclear Medicine and Radiation Safety


Nuclear medicine procedures are among the safest diagnostic exams available. Radiopharmaceuticals are formulated and ordered specifically for each patient and exam requested, resulting in minimal radiation exposure. The radiation risk is very low compared with the potential benefits.
