Appearance of capillary telangiectasias in diffusion-weighted MRI

Ziele: Objective: To evaluate the appearance of capillary telangiectasias in the brain stem in diffusion-weighted MRI. Methode: 18 patients with infratentorial capillary telangiectasias in the pons were examined using a 1.5 T whole boldy system (Magnetom Symphony, Siemens, Erlangen, Germany) with the standard head coil. The imaging protocol included T2-w turbo spin-echo, T1-weighted conventional spin-echo, diffusion-weighted gradient-echo (b-values=0, 500, 1000), all acquired in the transverse orientation before and T1-w conventional spin-echo in transverse and sagittal orientation, as well as T1-w gradient-echo…
