Hospital 3D printing: Part 2 -- A clear path to value capture
A key part of starting a 3D printing service or lab is demonstrating its value capture. Bill O'Connell of Materialise and Edward Stefanowicz of Geisinger Health System describe 12 potential value-capture areas associated with hospital 3D printing in part 2 of their series.

EVT promising in patients with extracranial ICA occlusions
Endovascular thrombectomy (EVT) and best medical treatment are both effective and safe options for patients with acute extracranial internal carotid artery 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.
