PURPOSE: To quantify the detectability of peripheral artery stenosis on hybrid CT angiography (CTA) reformations. METHODS: Hybrid reformations were developed by combining multipath curved planar reformations (mpCPR) and maximum intensity projections (MIP). Fifty peripheral CTAs were evaluated twice: either with MIP, mpCPR and axial images or with hybrid reformations only. Digital subtraction angiography served as gold standard. RESULTS: Using hybrid reformations, two independent readers detected 88.0% and 81.3% of significant stenosis, respectively. However, CTA including axial images detected statistically significant more lesions (98%). CONCLUSION: Peripheral CTA reading including axial images is still recommended. Further improvement of these hybrid reformations is necessary.
