Abstract
Factors related to clinical history and physical examination (previous trauma or recent radionuclide studies), related to patient’s condition (age, body habitus, underlying diseases, medications, hydration status, lack of cooperation during scanning), related to radiopharmaceuticals (radiochemical impurities, introduction of air into vial during preparation), related to technique (intra-arterial injection, extravasation, suboptimal image due to inadequate count collection, full bladder), and related to interpretation (normal and abnormal pattern recognition) are well-known possible sources of diagnostic errors [1].
Recently, SPECT/CT has been introduced, and the additional role of SPECT/CT has been stressed: enabling accurate diagnosis through enhanced sensitivity of SPECT and additional anatomic information from CT.
In this section, clinical cases of some classical artifacts associated with technical and patient-related factors and clinical cases of whole-body bone scan with equivocal diagnosis at presentation, which were correctly diagnosed with additional SPECT/CT, will be presented.
