Digital variance angiography enables up to 80% reduction in stationary acquisition radiation dose during prostatic artery embolization: a prospective randomized trial - European Radiology Objectives Digital variance angiography (DVA) has demonstrated superior image quality compared to digital subtraction angiography (DSA), but its potential remains underexplored for complex…

They demonstrated that DVA significantly improves image quality compared to DSA, particularly in the acquisition using ultra low dose protocol, which can reduction up to 80% of radiation burden to patients and interventionists. #InterventionalRadiology #RadiationSafety #DoseReduction #InnovationInIR
