We aimed to plot the growth curve of the fetal clavicle, identify gestational date-independent parameters. Using 2-dimensional ultrasonography, we obtained the clavicle lengths (CLs) from 601 normal fetuses between 12 and 40 gestational age (GA). The CL/fetal growth parameters ratio was calculated. Moreover, 27 cases of fetal growth restriction (FGR) and 9 cases of small for GA (SGA) were detected. In normal fetuses, the mean CL (mm) = -68.2 + 29.80 × ln(GA) ± Z × (1.07 + 0.02 × GA). A linear relationship was detected between CL and head circumference (HC), biparietal diameter, abdominal circumference and femoral length with R2 values of 0...

Pelvic pain may be caused by disorders of the reproductive, urinary, or gastrointestinal systems. In the pediatric population, pelvic pain is often first evaluated with ultrasonography, with other imaging modalities reserved for further workup or specific indications. Radiologists must be aware of the findings associated with common pelvic emergencies to allow prompt diagnosis and prevention of life-threatening complications. Although the range of pelvic pathology is extensive, this pictorial review presents ultrasound examples of common nontraumatic causes of pelvic pain encountered in the pediatric population, with a brief discussion about multimodality imaging features...

Tumor angiogenesis is an essential factor for tumor growth and antiangiogenic therapy. To simulate the blood perfusion characteristics of human renal cell carcinoma (RCC) longitudinally in the process of tumor growth, multimodal ultrasound examination was performed on 40 orthotopic xenograft RCC mouse models. According to tumor maximum diameter ( d ), tumor growth progress was divided into 3 steps: d ≤ 5 mm, 5 mm < d ≤ 10 mm, and d > 10 mm. Color Doppler flow imaging (CDFI), superb microvascular imaging (SMI), and contrast-enhanced ultrasound were administered to monitor tumor perfusion characteristics...

Midurethral sling (MUS) surgical procedures, in which a polypropylene synthetic mesh graft is transvaginally placed to support the urethra and manage stress urinary incontinence (SUI), is commonly performed (Urology. 2013;82(1):38-41; Radiology. 2018;289(3):728-729). Within 10 years of sling placement, about 1 in 20 women undergo subsequent surgery to revise their mesh, in which the mesh is cut or partially excised (Obstet Gynecol. 2019;133:1099-1108). Translabial ultrasound (TLUS) has been described as a sensitive technique for viewing MUS, although few studies have evaluated its ability to view surgically revised MUS (Radiology...
