Multiple Myeloma Guidelines and Their Recent Updates: Implications for Imaging.
In 2014, the diagnostic criteria for multiple myeloma were updated, leading to revised recommendations for imaging modalities and definition of therapy response. This review provides an overview of the current definitions of monoclonal plasma cell disease, diagnostic options, and changes relevant to radiologists. ⋯ · Mosebach J, Thierjung H, Schlemmer H et al.

Computed tomography (CT) is a central modality in modern radiology contributing to diagnostic medicine in almost every medical subspecialty, but particularly in emergency services. To solve the inverse problem of reconstructing anatomical slice images from the raw output the scanner measures, several methods have been developed, with filtered back projection (FBP) and iterative reconstruction (IR) subsequently providing criterion standards. Currently there are new approaches to reconstruction in the field of artificial intelligence utilizing the upcoming possibilities of machine learning (ML), or more specifically, deep learning (DL). ⋯ · Arndt C, Güttler F, Heinrich A et al.

Comparative Study
Influence of Thrombus Composition on Thrombectomy: ADAPT vs. Balloon Guide Catheter and Stent Retriever in a Flow Model.
A first-pass, direct aspiration technique and stent retrieval with a balloon guide catheter represent advanced thrombectomy techniques that are increasingly being used in the clinical routine. The purpose of this experimental study was to evaluate whether the techniques' effectiveness depended on the clot composition and to visualize the interaction between the devices and the clot. ⋯ · Madjidyar J, Pineda Vidal L, Larsen N et al.
