Frequency and Pattern of MRI Diffusion Restrictions after Diagnostic Catheter Neuroangiography.

(1) Background: We investigated the frequency, location, and lesion size of diffusion restrictions (DR) in magnetic resonance imaging (MRI) of asymptomatic patients after diagnostic angiography and assessed risk factors for their occurrence. (2) Methods: We analyzed diffusion-weighted images (DWI) of 344 patients undergoing diagnostic angiographies in a neuroradiologic center. Only asymptomatic patients who received a magnetic resonance imaging (MRI) examination within seven days after the angiography were included.

Spectrum of Complications and Complication Rates After Diagnostic Catheter Angiography in Neuroradiology.

Purpose: To retrospectively evaluate the total complication rates and type of complications after diagnostic cerebral and spinal catheter angiography.

Methods: Data from 2340 patients undergoing diagnostic angiography over a period of 10 years in a neuroradiologic center were retrospectively evaluated. Local, systemic, neurological, and technical complications were analyzed.
