Respiratory level tracking with visual biofeedback for consistent breath-hold level with potential application in image-guided interventions

Apr 26, 2019

This study aimed to present and evaluate a new respiratory level biofeedback system that helps the patient to have a consistent breath-hold level. The results showed an increased reproducibility of breath-hold expiration level in healthy volunteers, indicating a...

Splenectomy for hypersplenism with or without preoperative splenic artery embolisation

Apr 23, 2019

Due to the fact that intraoperative blood loss is a common occurrence in splenectomy, the authors set out to compare the perioperative and clinical outcomes of splenic artery embolisation (SAE) prior to splenectomy versus splenectomy alone. On a total of 100 patients,...

Dual-layer spectral computed tomography: measuring relative electron density

Mar 28, 2019

The goal of this study was to examine the feasibility and accuracy of a novel dual-energy CT technique in measuring the electron density. By using dual-layer CT (DLCT), the authors investigated two approaches to obtain relative electron densities. The results showed...

DNA breaks induced by iodine-containing contrast medium in radiodiagnostics: a problem of tungsten?

Mar 14, 2019

Iodine-containing contrast media (ICM) are often used to improve image quality and information content in x-ray-based examinations. There is, hovewer, increasing evidence that the use of ICM during CT sessions is associated with deoxyribonucleic acid (DNA) breaks that...

Evaluation of two collagen conduits and autograft in rabbit sciatic nerve regeneration with quantitative magnetic resonance DTI, electrophysiology, and histology

Mar 7, 2019

The authors of this study set out to evaluate two nerve conduit types, Nerbridge™ and NeuraGen®. They also aimed to compare the effectiveness of nerve regeneration between autograft and those two nerve conduits by using DTI, electrodiagnostic testing, limb function,...

Augmented reality for interventional oncology: proof-of-concept study of a novel high-end guidance system platform

Feb 28, 2019

This study was conducted to assess the feasibility of an innovative system that uses augmented reality to guide interventional oncology procedures. By performing experiments on three models, the authors deduced that the augmented reality can assist with needle...
