Particle Tracing Based on 4D Flow Magnetic Resonance Imaging: A Systematic Review into Methods, Applications, and Current Developments.

Background: Particle tracing based on 4D Flow MRI has been applied as a quantitative and qualitative postprocessing technique to study temporally evolving blood flow patterns.

Purpose: To systematically review the various methods to perform 4D Flow MRI-based particle tracing, as well as the clinical value, clinical applications, and current developments of the technique.

Study Type: The study type is systematic review.

Optical Navigation of the Drop-In γ-Probe as a Means to Strengthen the Connection Between Robot-Assisted and Radioguided Surgery.

With translation of the Drop-In γ-probe, radioguidance has advanced into laparoscopic robot-assisted surgery. Global-positioning-system-like navigation can further enhance the symbiosis between nuclear medicine and surgery. Therefore, we developed a fluorescence-video-based tracking method that integrates the Drop-In with navigated robotic surgery.

Prognostic value of handgrip strength in people aged 60 years and older: A systematic review and meta-analysis.

Aim: The aim of the present study was to systematically review the literature on the predictive value of handgrip strength as a marker for vulnerability. Furthermore, we aimed to update a recent systematic review on the association between handgrip strength and mortality.

Methods: Literature searches using Cochrane, PubMed and Embase databases, and searching reference lists of included studies.
