What is the difference between spect and pet?

SPECT (Single Photon Emission Computed Tomography) and PET (Positron Emission Tomography) are both medical imaging techniques used to study the anatomy and function of organs and tissues in the body. The main difference between the two lies in the type of radioactive tracers used. SPECT uses gamma-ray emitting radiotracers, whereas PET uses positron-emitting radiotracers. Additionally, PET provides more detailed and quantitative information about physiological processes as it measures the concentration and metabolism of the tracer, while SPECT primarily focuses on anatomical structures and blood flow. Despite these differences, both SPECT and PET are crucial in aiding the diagnosis and monitoring of various diseases, including cancer, heart disease, and neurological disorders.
