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 ...

Exploring the Dynamics of Ischemia and Reactive Hyperemia With Skeletal Muscle Blood Oxygen Level Dependent MRI in Patients With Peripheral Artery Disease, Age‐Matched Controls, and Young Healthy Subjects

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Skeletal muscle blood oxygen level dependent (BOLD) MRI is a technique for assessing vascular function in peripheral limbs. In patients, however, an increased frequency of atypical response patterns has been observed, warranting investigation into its underlying causes.

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).

The Importance of Patient Positioning in Radiography When Utilising Automatic Exposure Control

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study highlights the impact of inaccurate patient positioning on dose and image quality when utilising the automatic exposure control (AEC) for radiographic examinations. While the AEC serves to optimise radiation dose to patients, the results here demonstrate that poor positioning can lead to significant dose implications for patients.
