Implementation and Performance of First‐Trimester Referral Ultrasound Scan Following the Introduction of National Guidelines

Journal of Clinical Ultrasound, EarlyView.
The expert assessment of fetal anatomy before 14 weeks is feasible when adopting a standardized protocol and allows an early diagnosis in most cases at risk for fetal anomaly following first trimester screening ultrasound. ABSTRACT Background To report the implementation across Fetal Medicine units and the agreement between first and second trimester ...

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

Journal 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 ...

Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...

Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

Journal of Raman Spectroscopy, EarlyView.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...
