An Activity Tracker-Guided Physical Activity Program for Patients Undergoing Radiotherapy: Protocol for a Prospective Phase III Trial (OnkoFit I and II Trials).

Background: The positive impact that physical activity has on patients with cancer has been shown in several studies over recent years. However, supervised physical activity programs have several limitations, including costs and availability. Therefore, our study proposes a novel approach for the implementation of a patient-executed, activity tracker-guided exercise program to bridge this gap.

Acquisition-weighted chemical shift imaging improves SLOOP quantification of human cardiac phosphorus metabolites.

Purpose: Phosphorous metabolite ratios in human myocardium were determined by a combination of acquisition weighted CSI and a SLOOP evaluation and the results were compared to corresponding SLOOP experiments using standard CSI.

Materials And Methods: 10 healthy subjects were examined at 1.5 T using both standard CSI and acquisition weighted CSI.
