Radiation dose optimization in coronary CT angiography clinical application of absolute phase gating in patients with atrial fibrillation

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Atrial fibrillation (AF) poses significant challenges for coronary CT angiography (CCTA) due to R‐R interval variability, often necessitating high radiation dose protocols. Absolute phase gating, which uses fixed millisecond delays rather than percentage‐based cardiac cycle timing, may optimize image quality while reducing radiation

Explainable machine learning for patient‐specific quality assurance in intensity‐modulated radiotherapy based on anatomical structures

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Patient‐specific quality assurance (PSQA) plays a pivotal role in intensity‐modulated radiotherapy (IMRT) to ensure accurate dose delivery. However, conventional measurement‐based PSQA approaches are labor‐intensive and provide limited insight into the underlying factors contributing to variations in gamma passing rates (GPRs ...

Chronic Spontaneous Coronary Artery Dissection in a Young Woman Managed With Coronary Artery Bypass Grafting: A Case Report With Literature Review

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Spontaneous coronary artery dissection (SCAD) is an uncommon, non‐atherosclerotic cause of acute coronary syndrome, typically occurring in young to middle‐aged women. Although most cases resolve spontaneously with conservative therapy, a small proportion develop chronic dissections that require revascularization.

Advanced Uterine Carcinosarcoma With Fatal Suspected Pulmonary Embolism in a Resource‐Limited Setting: A Rare Case Report

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Uterine carcinosarcoma (UCS), also known as malignant mixed Müllerian tumor (MMMT), is a biphasic neoplasm characterized by the presence of carcinomatous (epithelial) and sarcomatous (stromal tissue) elements. It frequently presents at an advanced stage and can mimic primary ovarian carcinoma on clinical and radiological evaluation ...

Physical Adaptations to High‐Intensity Multimodal Training in Recreationally Active Adults: A Randomised Control Trial

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 7, July 2026.
ABSTRACT High‐intensity multimodal training (HIMT), combines aerobic and resistance exercise within a single session, offering a time‐efficient training mode. However, the efficacy of HIMT for physical adaptations compared to other combined training models (e.g., inter‐session concurrent training [ISCT]) remains unclear.
