Pulmonary Embolism Diagnosis and Mortality With Pulmonary CT Angiography Versus Ventilation-Perfusion Scintigraphy: Evidence of Overdiagnosis With CT?
American Journal of Roentgenology, 05/30/2012
Sheh SH et al. – The results of this study are evidence that the shift in imaging from V/Q scintigraphy to pulmonary CT angiography (CTA) resulted in increased diagnosis of a less fatal spectrum of pulmonary embolic disease, raising the possibility of overdiagnosis. Outcome–based clinical trials with long–term follow–up would be helpful to further guide management.
