Enhanced Transrectal Ultrasound, Real-Time Sonoelastography, and Contrast-Enhanced Transrectal Ultrasound in Heavily Prescreened Chinese Men With Naive and Repetitive Biopsy: A Comparison of Detection Rate of Prostate Cancer Per Man and Per Lesion
Multiparametric magnetic resonance imaging and targeted biopsy have been widely accepted as the most accurate technique to detect localize prostate cancer. It is a time-consuming and expensive option and may not be widely available in China, making ultrasound the first choice for the detection of prostate cancer. In this current retrospective study, the diagnostic values of enhanced transrectal ultrasound, contrast-enhanced transrectal ultrasound, and real-time sonoelastography were evaluated. Symptomatic 315 men older than 40 years with prostate-specific antigen level greater than 4.0 ng/mL, with abnormal digital rectal e...

Ultrasound of the Normal and Abnormal Vas Deferens
The extrapelvic portion of the vas deferens is readily visible with ultrasound but often overlooked. Several publications have described the scanning technique and the normal anatomy of the vas deferens. Sonographic evaluation of the vas deferens provides critical information in the workup of male infertility. Obstruction, inflammatory conditions, and neoplasms of the vas deferens can also be diagnosed with ultrasound. Knowledge of the normal and abnormal appearance of the vas deferens improves scans of the scrotum and expands the conditions that can be recognized and accurately diagnosed with ultrasound.

Polyorchidism: A Review of the Literature and Case Report of a Third Testicle Presenting as an Inguinal Hernia
Polyorchidism, a very rare congenital anomaly, refers to the presence of more than 2 testes. It is often associated with many other pathologies including cryptorchidism, varicocele, testicular malignancy, and inguinal hernias. (Source: Ultrasound Quarterly)

Pitfalls and Practical Challenges in Imaging of the Pediatric Scrotum
Ultrasound is the modality of choice for evaluation of the pediatric scrotum, as it provides excellent image quality without the use of radiation, need for sedation/anesthesia, or use of contrast material and can be used for serial examination. Ultrasound of the scrotum has proven to be useful for assessment of a wide gamut of congenital, infectious, inflammatory, endocrine, neoplastic, and traumatic abnormalities in pediatric patients of all ages from the tiniest premature infant to a fully grown young adult. This review article presents a varied spectrum of conditions that may affect the pediatric scrotum, what the radio...

Impact Factor JUMPS After the 2020 COVID-19 Pandemic: A Retrospective Study in: Radiology, Nuclear Medicine & Medical Imaging: Journals
In this study, we aimed to compare the growth rate of IF JUMPS in Radiology, Nuclear Medicine & Medical Imaging in the last 6 years. This retrospective study calculated the growth rate (JUMP) in IF from 2015 to 2020. We used the Friedman and Wilcoxon signed ranks tests to calculate the statistically significant difference in IF from 2015 to 2020 and the 2019 to 2020 difference. We classified JUMPS in negative growth rate, quartiles, and journals with>100%. Three journals had more than 100% IF growth rate during 2020 (Zeitschrift fur Medizinische Physik, Journal of the Belgian Society of Radiology, and Ultrasound Quarterly)...

Arrival-Time Parametric Imaging in Contrast-Enhanced Ultrasound for Diagnosing Fibrosis in Primary Biliary Cholangitis
Liver biopsy is usually required for diagnosing fibrosis in primary biliary cholangitis (PBC), but contrast-enhanced ultrasonography (CEUS) is a possible alternative. The aim of this study was to investigate arrival-time parametric imaging (At-PI) in for diagnosing fibrosis in PBC. Forty-eight patients (male/female, 8/40; mean age, 60 ± 13 years) with PBC diagnosed by liver biopsy underwent CEUS during 2009–2019. Of these, 27 who also underwent shear wave elastography (SWE) were further analyzed. Perflubutane was intravenously injected and CEUS performed. Contrast dynamics of hepatic segment V and the right kidney were ...

Transabdominal Ultrasound Evaluation of Pancreaticobiliary Maljunction in Children
The development of high-frequency ultrasound made the diagnosis of pancreaticobiliary maljunction (PBM) possible. However, no study has been performed to clarify the sensitivity and specificity of transabdominal ultrasound (TAUS) in the diagnosis of PBM. The purpose of this study was to evaluate the accuracy of TAUS in the diagnosis of pediatric PBM and to assess factors that may influence the accuracy of ultrasound. This was a prospective study and 43 patients with suspected PBM were enrolled. All of these patients underwent TAUS examination to detect the pancreaticobiliary ductal union. Final diagnoses were determined by...

Etiological Diagnosis of Linear-Array Endoscopic Ultrasonography in Distal Common Bile Duct Dilatation
The etiology of distal common bile duct (CBD) dilatation is complex. Linear-array endoscopic ultrasonography (EUS) can not only visualize the distal and surrounding structures of the bile duct closely but also obtain pathological specimens by fine-needle aspiration, which provides an important basis for the diagnosis and differential diagnosis. The purpose of this study was to evaluate the diagnostic value of linear-array EUS in the etiology of distal CBD dilatation. Patients with distal CBD dilatation underwent linear-array EUS in the endoscopic center of The Second Affiliated Hospital of Soochow University and Traditiona...

Preliminary Exploration on the Value of Shear Wave Elastography in Evaluating the Effectiveness of Microwave Ablation on Hepatic Malignancies
This study aimed to investigate the value of SWE in evaluating the effectiveness of microwave ablation in hepatic malignancies. A total of 24 patients (including 30 lesions) with liver malignancies receiving microwave ablation treatment at the Cancer Hospital of Guangzhou Medical University from April 2018 to January 2019 were enrolled. The elastography was performed within 1 week before and after ablation. The SWE values in the central zone, the marginal zone of the lesion, and peripheral liver parenchyma were collected and analyzed. Before ablation, the mean of SWE value was 65.80 ± 13.37 kPa for the central zone of the...

Can Location of Stiffness Measurement Impact Spleen 2-Dimensional Shear Wave Elastography Measurement?
Ultrasound-based spleen elastography is a promising surrogate to predict portal hypertension noninvasively. In contrast to defined standards for liver stiffness measurement, the standardized examination procedures for 2-dimensional (2D) shear wave elastography spleen elastography have not been established yet. The aim was to investigate the impact of location of stiffness measurement on 2D shear wave elastography spleen stiffness measurement (SSM). Patients with splenomegaly were enrolled. Both B-mode ultrasound and elastography of spleen were performed. For SSM, 3 regions were chosen for spleen measurement: lower pole reg...
