Accuracy of X-ray with perfusion scan in young patients with suspected pulmonary embolism.
Thrombosis Research(2015)
Abstract
•Concerns have been raised regarding the risk of cancer following radiation with CTPA.•We directly compared X-ray plus Q-scanning and CTPA, using the PISAPED criteria.•We include 76 patients aged ≤50years with suspected PE.•The PPV was 71% (95% CI 50-86%), and NPV of 83% (95% CI 71-91%).•X-ray and perfusion scanning using the PISAPED criteria seem less safe than CTPA.
