Non-contrast Enhanced Magnetic Resonance Angiography (nc-mra) Is A Viable Diagnostic Alternative To Conventional Contrast Enhanced Mra (ce-mra) In Children

摘要

Background: In light of recent concerns about the safety of radiation associated with CT scans and MRI contrast agents, there is increasing need for non-contrast enhanced magnetic resonance angiography (NC-MRA), particularly for pediatric subjects. The aim of this study was to assess the quality and feasibility of NC-MRA. In 15 patients referred for thoracic angiography, we compared NC-MRA with conventional contrast enhanced MRA (CE-MRA). To assess feasibility of NC-MRA in children, we performed NC-MRA in 49 consecutive pediatric subjects. Methods: Fifteen patients (17-73 years old) underwent both NC-MRA and CE-MRArnfor comparison purposes.
