Liver biopsy remains the reference standard for the assessment of liver fibrosis, but this procedure is invasive and can lead to complications. Thus, studies to determine the optimal noninvasive test are warranted. This study compared several noninvasive tests and their combinations for evaluating liver fibrosis stages in patients with chronic hepatitis B. ⋯ The SWV, APRI, and FIB-4 were valid tests for evaluating substantial liver fibrosis and cirrhosis. The combination of these tests with several noninvasive indicators is expected to enhance the assessment of liver fibrosis stages.

In this series, we aimed to describe the sonographic findings of chondral avulsion fractures that develop concomitant with lateral ankle ligament injury in children. We performed stress sonography during a manual anterior drawer stress procedure of the ankle in 9 skeletally immature patients who had recently had a lateral ankle sprain. Echo videos were obtained through the course of treatment, and all videos were reviewed. ⋯ In contrast, the features of chondral fractures on stress sonography included abnormal motion of the chondral lesions and mobility/fluidity of hyperechoic spots along the chondral fracture site. The presence of hyperechoic spots around the chondral lesion is an important sonographic sign for diagnosing chondral fractures concomitant with ankle lateral ligament injury. Hence, we believe that stress sonography should be considered for the detection of chondral fractures concomitant with radiographically negative ankle lateral ligament injuries in skeletally immature patients with lateral ankle pain and ankle sprains, if hyperechoic spots are present in the cartilage of the distal fibula.

Transvaginal sonography is the first-line imaging modality used to evaluate acute female pelvic pain in the emergency setting because of its accessibility, lack of ionizing radiation, and excellent ability to identify reproductive tract disorders. Although the intent of transvaginal sonography is to evaluate the reproductive organs, imaging of adjacent pelvic structures is an important part of every transvaginal sonographic examination. Gastrointestinal, urologic, and vascular disorders incidentally scanned on transvaginal sonography may explain the pain for which the examination is being performed. In such cases, transvaginal sonography may play an important role in the diagnostic process if the clinician is aware of the transvaginal sonographic appearance of these entities.

Comparative Study
Greater Trochanteric Pain Syndrome: Percutaneous Tendon Fenestration Versus Platelet-Rich Plasma Injection for Treatment of Gluteal Tendinosis.
The purpose of this study was to compare ultrasound-guided percutaneous tendon fenestration to platelet-rich plasma (PRP) injection for treatment of greater trochanteric pain syndrome. ⋯ Our study shows that both ultrasound-guided tendon fenestration and PRP injection are effective for treatment of gluteal tendinosis, showing symptom improvement in both treatment groups.

The aim of this study was to explore the sonographic and elastographic properties of patellar and Achilles tendons in smoking and nonsmoking otherwise healthy adults. ⋯ Thickness and strain ratio measurements of patellar and Achilles tendons were reduced (thinner and harder tendons) in smokers. Clinical implications of these morphologic and elastographic changes should be investigated in future studies.
