Prospective Comparison of DWI‐Derived Virtual MR Elastography and Conventional MR Elastography in Metabolic Dysfunction‐Associated Steatotic Liver Disease and Healthy Volunteers

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Virtual MR elastography (VMRE) and MRE have been proposed for liver fibrosis staging in metabolic dysfunction‐associated steatotic liver disease (MASLD), but VMRE's diagnostic performance remains debated. Purpose To assess the inter‐visit and inter‐reader reproducibility of fat‐uncorrected and fat‐corrected diffusion‐weighted ...

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Non‐Subtractive Arterial Spin Labeling‐Based (NSASL) Renal Magnetic Resonance Angiography (MRA): Development and Clinical Feasibility Evaluation

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Non‐contrast renal MR angiography (MRA) is valuable for patients who cannot receive contrast agents or when avoiding radiation is desired. However, the conventional inflow inversion recovery (IFIR) method is limited by incomplete background suppression, venous contamination, and motion sensitivity.

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

Comparison of Auto‐Contouring Tools for Delineation of Normal Organs at Risk in Paediatric Patients Undergoing Radiotherapy

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Contouring organs at risk (OARs) manually in paediatric patients undergoing cranial‐spinal radiation therapy (CSI) is a time‐consuming, labour‐intensive task. This study aims to assess the accuracy and clinical acceptability of auto‐contours produced by the Siemens DirectORGANS auto‐contouring software on paediatric patients receiving CSI treatment ...

Developmental outcomes after soybean oil vs mixed‐oil intravenous lipid emulsions in neonates: A secondary analysis of a clinical trial

open access: yesJournal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Fatty acids make up a significant portion of brain mass. The choice of lipid injectable emulsion alters a patient's fatty acid profile. In neonates with intestinal failure dependent on parenteral nutrition, this is particularly concerning given their rapid brain development. Methods We randomly assigned 24 infants to receive soy oil
