SPECT stands for which acronym?

SPECT stands for which acronym?

• A. single photon emission computed tomography
• B. spectral photon emission tomography
• C. scanned photon emission computed tomography
• D. simple photon emission computed tomography

Answer: (A)

The main idea is to know what SPECT stands for in nuclear medicine imaging. It expands to single photon emission computed tomography. Each word matches the acronym: S for single, P for photon, E for emission, C for computed, and T for tomography. This reflects how the technique works—detecting individual gamma photons emitted by a radiotracer and using computer reconstruction to create cross-sectional 3D images. The other options aren’t used because they don’t describe the standard terminology: spectral would imply a range of energies, scanned isn’t part of the acronym, and simple isn’t the established descriptor.
