Evaluation of Sonographic Muscle Measurement Using Established Muscle Markers.

Objectives: Loss of muscle quantity and function is associated with frailty and reduced quality of life. Sonography is a simple option to quantify muscle mass, which could be included into routine diagnostic workup. This study was designed to prospectively evaluate sonographic measurement and to compare it with established measurements of muscle quantity and function.

Structured reporting for efficient epidemiological and in-hospital prevalence analysis of pulmonary embolisms.

Structured reporting (SR) not only offers advantages regarding report quality but, as an IT-based method, also the opportunity to aggregate and analyze large, highly structured datasets (data mining). In this study, a data mining algorithm was used to calculate epidemiological data and in-hospital prevalence statistics of pulmonary embolism (PE) by analyzing structured CT reports.All structured reports for PE CT scans from the last 5 years (n = 2790) were extracted from the SR database and analyzed.

Photon-Counting Detector CT Virtual Monoenergetic Images for Coronary Artery Stenosis Quantification: Phantom and In Vivo Evaluation.

Calcium blooming causes stenosis overestimation on coronary CTA. The purpose of this article was to evaluate the impact of virtual monoenergetic imaging (VMI) reconstruction level on coronary artery stenosis quantification using photon-counting detector (PCD) CT. A phantom containing two custom-made vessels (representing 25% and 50% stenosis) underwent PCD CT acquisitions without and with simulated cardiac motion.

Minimal invasive aortic arch repair with suture-mediated closure system.

Port implantation can be associated with an array of serious vascular complications, typically involving the subclavian artery. We report a case in which implantation of a port resulted in iatrogenic perforation of the aortic arch at the level of the left subclavian artery, which was sealed off using a percutaneous vascular closure device.
