The sonographic changes occurring during post transplant acute tubular necrosis and rejection are discussed. Seven patients with proven ATN are shown to maintain normal sonographic features and exhibit normal hypertrophy. In contrast during acute rejection the findings in 21 patients included in order of frequency the following 1) sudden increase in renal volume, 2) prominent medullary pyramids, 3) abnormal echogenicity, 4) decreased amplitude of the central sinus echoes, 5) increased cortical thickness, 6) crescent shaped fluid collections and 7) indistinct corticomedullary boundary.

Clinical Features and Ultrasonographic Manifestations of Retroperitoneal Nerve Sheath Tumors.
Curr Med Imaging
January 2025
Department of Ultrasound, Peking University International Hospital, Beijing, China.
Article Synopsis
- Retroperitoneal nerve sheath tumors are rare, and distinguishing between benign and malignant types is crucial for treating patients effectively.
- A study analyzed 49 patients with benign tumors using ultrasound imaging, applying Adler's grading system to assess tumor characteristics and perform statistical analyses.
- The findings highlight key differences between benign and malignant tumors, such as size and shape, with a maximum diameter of 9.9 cm being a significant indicator of malignancy, suggesting that ultrasonography can enhance diagnostic accuracy and inform treatment approaches.
Nomogram for predicting the efficacy of high-intensity focused ultrasound ablation for uterine fibroids based on oxytocin experimentation and ultrasonographic features: a retrospective single-center study.

State Key Laboratory of Ultrasound in Medicine and Engineering, College of Biomedical Engineering, Chongqing Medical Unibersity, Chongqing, China.
Article Synopsis
- Developed a nomogram to predict the effectiveness of high-intensity focused ultrasound (HIFU) for treating uterine fibroids by analyzing oxytocin levels and sonographic features of fibroids.
- Conducted a retrospective study of 60 patients, utilizing logistic regression to identify key predictive factors like myoma type, blood flow, and oxytocin classification, resulting in a model assessed using R language.
- The model demonstrated strong predictive ability with an area under the curve of 0.887 and good calibration, suggesting it can effectively guide clinicians in selecting appropriate patients for HIFU treatment.

Department of Radiology, University of Lahore Teaching Hospital, Lahore, Pakistan.
Introduction: Monitoring the morphological features of the gestational sac (GS) and measuring the mean sac diameter (MSD) during early pregnancy are essential for predicting spontaneous miscarriage and estimating gestational age (GA). However, the manual process is labor-intensive and highly dependent on the sonographer's expertise. This study aims to develop an automated pipeline to assist sonographers in accurately segmenting the GS and estimating GA.

Background/aim: Cesarean section (CS) is a widely performed operation worldwide but data about uterine closure are lacking. We aimed to evaluate scar niches and compare single-layer and double-layer uterine closure at 6 months following CS.
Materials And Methods: This prospective randomized trial assessed 56 women undergoing single- or double-layer uterine closure.
