What are the two main types of imaging performed in nuclear medicine?

The correct answer identifies the two main types of imaging performed in nuclear medicine as planar imaging and SPECT (Single Photon Emission Computed Tomography).

Planar imaging is a fundamental technique in nuclear medicine where a two-dimensional image is obtained, usually through the use of a gamma camera. This method allows for the visualization of radiotracer distribution in the body, helping in various diagnostic scenarios. It provides critical information regarding organ function and pathology.

SPECT, on the other hand, is a more advanced imaging modality that provides three-dimensional images by detecting gamma rays emitted from the radiotracer during its decay. SPECT offers enhanced spatial resolution and can provide more detailed information about physiological processes, making it a powerful tool in diagnosing and monitoring various diseases, including cardiac and neurological conditions.

The distinction between these two modalities is significant in the field of nuclear medicine, as they each serve unique roles in the assessment of patient health. Together, planar imaging and SPECT represent the core imaging techniques utilized by nuclear medicine professionals to diagnose and understand complex medical conditions.
