Overview
SPECT CT merges functional SPECT images with CT anatomy to enhance localization and diagnostic specificity.
Technique
CT can be low dose for localization or diagnostic quality. SPECT reconstruction and attenuation correction improve quantification.
Clinical Uses
Bone SPECT CT for occult fractures infection localization and parathyroid imaging.
Limitations and Safety
Radiation from both components. Careful protocol selection minimizes dose while preserving diagnostic value.
