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

Comparison of the SMI Technique and CEUS for the Assessment of Microvasculature in Leiomyosarcoma and Its Clinical Value for Application

Journal of Clinical Ultrasound, EarlyView.
SMI and CEUS can clearly reflect the microvascular situation in fibroids and effectively guide the clinical treatment of patients with uterine fibroids, but the effect of SMI is better than that of CEUS in guiding the treatment of patients, which can provide a reference for the selection of clinical treatment programs.

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 ...

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 ...
