Hybrid SPECT/CT augmented lung perfusion scintigraphy for diagnosis of pulmonary thromboembolism: Assessment of superiority over conventional planar imaging and comparative evaluation of interpretation criteria (Modified PIOPED II and PISAPED).

Conclusion: Hybrid SPECT/CT (Q) imaging has a high diagnostic accuracy for detecting PTE than planar (Q) scans interpreted with chest radiographs. In addition, low dose CT used in SPECT/CT was able to identify other non-embolic pathologies (eg: pneumonia, emphysematous bullae, tumor or lymphadenopathy) responsible for perfusion defects which could have been missed on chest radiography thereby increasing the specificity. Modified PIOPED II had a higher number of non-diagnostic results compared to PISAPED which increases the latter's clinical utility.
