From: Digital variance angiography allows about 70% decrease of DSA-related radiation exposure in lower limb X-ray angiography

Figure 4

Comparison of representative normal dose (1.2 µGy/frame) DSA100 (left column) and low-dose (0.36 µGy/frame) DVA30 (right column) images obtained in the abdominal (upper row), femoral (middle row) and crural (lower row) region. The corresponding Image pairs were taken from the same patient and same direction in two consecutive runs, but the different regions belong to different patients. Brightness/contrast adjustments and pixel shift were applied to DSA and DVA images using the Siemens Syngo and the Kinepict workstation, respectively. Abbreviations: DSA: Digital Subtraction Angiography; DVA: Digital Variance Angiography.
