Overview
The traditional gold standard for diagnosing PE is contrast pulmonary angiography. However, invasiveness, its high costs, limited availability and need of an expert radiologist are some of its negative aspects. This chapter deals with the advantages of multidetector CT over CTPA.
Single Detector CT
Recent improvement in technology has changed the value of CT angiography for decision making in suspected PE patients. Wide variations regarding both sensitivity (53-100%) and specificity (73-100%) was reported in studies about single detector spiral CT in suspected PE cases.[1][2]
Two large multicentric robust clinical studies including more than 1000 patients reported a sensitivity around 70% and a specificity of 90% for single-detector CT.[3][4]
