Late gadolinium enhancement in mitochondrial myopathy: a systematic review and meta-analysis of cardiovascular magnetic resonance studies
Sep 22, 2026
The authors aimed to determine the prevalence and distribution of late gadolinium enhancement (LGE) in patients with mitochondrial myopathy (MM) using cardiac magnetic resonance (CMR) imaging. Their systematic review and meta-analysis of five studies revealed that approximately 20.72% of MM patients exhibited LGE, predominantly in the inferolateral region of the myocardium. These findings highlight the potential of CMR to detect subclinical cardiac involvement in MM, although further research is needed to understand the prognostic implications of LGE in this patient population.
Prospective study to evaluate radiation dose and image quality in two-dimensional (2D) lower limb angiographic images acquired with a novel contrast-to-noise ratio (CNR)-driven exposure control protocol
Sep 19, 2026
The authors aimed to evaluate the effectiveness of a novel contrast-to-noise ratio (CNR)-driven exposure control protocol (OPTIQ) in reducing radiation dose during lower limb angioplasty while maintaining image quality compared to a conventional dose protocol (CDP). The study found that OPTIQ significantly reduced radiation exposure for patients and operators by approximately 60%, without compromising the diagnostic quality of the images. This suggests that OPTIQ aligns with the principles of minimizing radiation exposure in medical procedures.
Medical image sharing 2026 best practice laws, legislation and regional variance
Sep 18, 2026
The authors investigate the evolving legal and ethical landscape surrounding the sharing of medical imaging for educational purposes, particularly in light of updates to the UK GDPR. They aim to determine whether anonymisation alone is sufficient for legal compliance and explore the implications of recent regulatory changes on healthcare professionals' practices. The article concludes that a comprehensive approach, combining thorough de-identification, informed consent, and appropriate sharing methodologies, is essential to balance educational benefits with patient confidentiality.
Development and validation of a model combining bowel ultrasound and inflammatory biomarkers for evaluating disease activity in ulcerative colitis: a dual centre retrospective study
Sep 18, 2026
The authors aimed to develop and validate a model that combines bowel ultrasound and inflammatory biomarkers to assess disease activity in patients with ulcerative colitis. Their study demonstrated that specific ultrasound parameters and biomarkers could effectively predict disease activity, achieving a high diagnostic accuracy in both the derivation and external validation cohorts. The resulting nomogram offers a clinically practical tool for noninvasive patient management.
A formal neuroradiology second opinion service changes management in one in five cases: a retrospective cohort study of discrepancies and types of errors
Sep 18, 2026
The authors aimed to quantify the discrepancy rates between referring reports and subspecialist neuroradiology second-opinion reports, as well as to assess the clinical impact of these discrepancies. Their retrospective study found that over 42% of cases had discrepancies, with nearly 21% being major discrepancies that often led to significant changes in diagnosis and treatment. The study highlighted faulty reasoning as the predominant error type, suggesting the need for targeted quality improvement in neuroradiology interpretations.
Value of kinetic parameters of ultra-fast dynamic contrast-enhanced magnetic resonance inaging (MRI) for differentiating malignant and benign breast lesions: a retrospective study
Sep 11, 2026
The authors aimed to evaluate the diagnostic value of kinetic parameters from ultra-fast dynamic contrast-enhanced magnetic resonance imaging (UF DCE-MRI) in distinguishing between benign and malignant breast lesions. Their retrospective study found that parameters such as maximum slope, area under the curve, and maximum peak of the curve effectively differentiated the two types of lesions, particularly in mass enhancement cases, while time to enhancement showed limited diagnostic efficacy. Overall, the study suggests that UF DCE-MRI kinetic parameters hold promise for improving breast lesion characterization.
Testicular shear-wave elastography in adult varicocele: associations with semen quality and clinical parameters
Sep 10, 2026
This study aimed to investigate the relationship between testicular shear-wave elastography (SWE) and semen quality in adult men with left-sided varicocele. The findings revealed that SWE-derived testicular stiffness was significantly associated with semen abnormalities, particularly on the left side, suggesting that while SWE can provide valuable functional insights, it should be interpreted alongside traditional clinical assessments rather than used as a standalone marker of varicocele severity.
Endometrial imaging
Sep 9, 2026
The authors aim to summarize the role of various imaging modalities in the diagnosis and management of endometrial disorders, including normal appearances and abnormalities such as polyps, hyperplasia, and endometrial cancer. They highlight the importance of transvaginal ultrasound as the first-line imaging technique, with additional insights on the use of MRI and CT for staging and follow-up. This review provides a comprehensive overview of endometrial imaging practices in the UK.
Effect of cardiac myosin inhibitors on cardiac structure and myocardial fibrosis in obstructive hypertrophic cardiomyopathy: a meta-analysis of cardiac magnetic resonance outcomes
Sep 9, 2026
This meta-analysis investigates the effects of cardiac myosin inhibitors (CMIs) on cardiac structure and myocardial fibrosis in patients with obstructive hypertrophic cardiomyopathy (oHCM) using cardiac magnetic resonance (CMR) outcomes. The findings indicate that CMIs significantly reduce left ventricular mass index, maximal left ventricular wall thickness, and left atrial volume index, but do not demonstrate a clear impact on myocardial fibrosis as measured by late gadolinium enhancement or extracellular volume fraction. Thus, while CMIs improve certain cardiac structural parameters in oHCM, their effect on myocardial fibrosis remains uncertain.
Assessment of image quality and radiation dose in low-dose, low-contrast computed tomography coronary angiogram: a systematic review and meta-analysis
Aug 29, 2026
The authors aimed to evaluate the image quality and radiation dose associated with low-dose, low-contrast computed tomography coronary angiography (CTCA). Their systematic review and meta-analysis of five studies demonstrated that using an 80 kV setting significantly reduces radiation exposure by 54-56% while maintaining comparable image quality to 100 kV, suggesting its potential for safer use in selected patients.
