Operating beyond 3T: Is clinical use in reach?
VIENNA - The standard field strength of clinical MR units is still 1.5 tesla, but the past five years have seen a tremendous increase in the number of devices operating at 3.0 tesla. In addition, whole-body systems up to 9.4 tesla have become available in experimental settings and have already proved to be significantly beneficial in special purpose examinations.

EVT promising in patients with extracranial ICA occlusions
Images depict a 49-year-old female participant with cryptogenic cirrhosis who presented with a 3.2-cm liver lesion. This biopsy-confirmed hepatocellular carcinoma (HCC) with an initial categorization of Liver Imaging Reporting and Data System (LI-RADS) category LR-4 (probably HCC) at CT was upgraded to LR-5 (definitely HCC) at contrast-enhanced ultrasound (CEUS). (A) Precontrast CT images in the liver show vague hypoattenuation in the medial left hepatic lobe (arrows). (B) Arterial phase images demonstrate no definite arterial phase hyperenhancement (arrows). (C) Washout and an enhancing capsule (arrows) on a late-phase image resulted in an LR-4 categorization. (D) B-mode ultrasound shows a round hypoechoic nodule (arrows). (E) An early-phase CEUS image shows clear arterial-phase hyperenhancement (arrows); (F) No washout at one minute (arrows), and (G) late, mild washout at four minutes (arrows) resulted in a CEUS LR-5 categorization.
