Among patients who received peripheral vascular interventions, a fluoroscopy frame rate of 7.5 frames per second led to a reduced radiation dose and comparable success compared with the standard of 15 frames per second, leading researchers to conclude that the lower rate should be considered during these procedures.
The retrospective analysis, which was published in the journal Vascular, included data from 87 consecutive peripheral vascular interventions (PVIs) performed at two medical centers from 2011 to 2012. Using the fluoroscopy frame rate, researchers divided patients into two groups: 7.5 frames per second (group A; n = 44) and 15 frames per second (group B; n = 43). They compared radiation dose and demographic, clinical and procedural characteristics and outcomes.
