Which organs are commonly studied with SPECT?

Which organs are commonly studied with SPECT?

• A. Brain, Liver, Bone Studies, Cardiac Perfusion
• B. Brain only
• C. Heart only
• D. Lungs only

Answer: (A)

SPECT imaging uses radiotracers to visualize how organs are functioning, not just their structure. It’s commonly applied to several key areas: brain perfusion imaging helps evaluate conditions like epilepsy, dementia, and stroke; bone scans reveal metabolic activity in the skeleton for fractures, infections, or metastatic disease; liver imaging can assess hepatic function and lesions; and cardiac perfusion imaging evaluates blood flow to the heart muscle to detect ischemia or infarction. Because these four areas represent routine, widely used SPECT applications, this combination best matches what SPECT is commonly used to study. While the lungs can be imaged in some SPECT protocols, the listed organs cover the major, standard uses of SPECT, making other choices limited to a single organ.
