Flowchart of the study. Following the enrollment procedure, the selected patients were redirected to the study module (dashed square), where the endpoints (CNR comparison and visual evaluation) were reached in a fully anonymized manner. Although both normal and low-dose images were acquired during the examinations, only the normal dose DSA images were used for diagnostic purposes. DVA images were generated retrospectively from the raw unsubtracted series by using the Kinepict Medical Imaging Tool v.3.0 (Kinepict Health Ltd, Budapest). Both the CNR comparison and visual evaluation were performed retrospectively. PAD: Peripheral Artery Disease; DSA: Digital Subtraction Angiography; DVA: Digital Variance Angiography, PACS: Picture Archiving and Communication System; CNR: Contrast-to-Noise Ratio. OGYÉI: National Institute of Pharmacy and Nutrition.
