Clinical performance of sFlt‐1/PlGF ratio triage in suspected pre‐eclampsia: A prospective, observational multicenter diagnostic‐triage study in South Africa (TsHEPPO study)

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To evaluate the diagnostic and short‐term predictive performance of the soluble fms‐like tyrosine kinase‐1/placental growth factor (sFlt‐1/PlGF ratio) in South African women with suspected pre‐eclampsia (PE), comparing thresholds of ≥ 33 and ≥ 38 in a predominantly African population.

Doppler Frequency Shift Prediction and Acquisition Method for High-Speed Aircraft Relative to Low Orbit Satellites

天地一体化信息网络
The rapid relative displacement between high-speed aircraft and low-Earth orbit (LEO) satellites causes Doppler frequency shifts, affecting signal synchronization, acquisition, and demodulation performance.

Study of Risk Factors and Image Findings of Isolated Abdominal Incidentally Detected Aortic Dissection

Journal of Clinical Ultrasound, Volume 53, Issue 3, Page 429-435, March/April 2025.
We detect the risk factors and image characteristics of incidentally detected IAAD. Independent risk factors of IAAD included fatty liver and smoking. In the ultrasound findings of IAAD, an intimal flap was frequently observed. In the CT scan, displacement of intimal calcifications was frequently observed. For suspected IAAD, the abdominal aorta should

Point‐Of‐Care Ultrasound for the Assessment of the Cerebroplacental Ratio in Near‐Term Pregnancies: An Agreement Study With Conventional Ultrasound

Journal of Clinical Ultrasound, EarlyView.
In 80 singleton pregnancies at term, handheld point‐of‐care ultrasound (POCUS) was compared with conventional ultrasound for fetal Doppler assessment. Umbilical artery PI, middle cerebral artery PI, and cerebroplacental ratio showed agreement between devices. Between‐device variability was comparable to intra‐observer repeatability, supporting handheld

When the Number Matters: Contextualising Australian Reference Values for 99ᵐTc‐Pertechnetate Thyroid Uptake

Journal of Medical Radiation Sciences, EarlyView.
Are the historical 1%–4% thyroid uptake reference values still valid in modern practice? This editorial examines why contemporary Australian and international data suggest otherwise and situates the new reference range reported by Wornes (https://doi.org/10.1002/jmrs.70078) and colleagues within the broader international literature.

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 ...
