Purpose: To assess the predictive value of an ultrasound-based radiomics-clinical nomogram for grading residual cancer burden (RCB) in breast cancer patients.
Methods: This retrospective study of breast cancer patients who underwent neoadjuvant therapy (NAC) and ultrasound scanning between November 2020 and July 2023. First, a radiomics model was established based on ultrasound images.
Article Synopsis
- The study investigates how contrast-enhanced ultrasound (CEUS) can be used to diagnose and grade bladder urothelial carcinoma (BUC) by analyzing data from 173 patients with bladder lesions.
- Results showed clear differences in blood flow and CEUS enhancement between BUC and benign lesions, with specific metrics (like the H/T ratio) effectively distinguishing between high and low grades of BUC.
- The findings suggest that using CEUS along with time-intensity curve analysis significantly enhances the diagnostic precision for identifying BUC and its severity.
Article Synopsis
- The study assessed the effectiveness of combining real-time contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT) for identifying three types of kidney cancer: clear cell renal cell carcinoma (CCRCC), papillary renal cell carcinoma (PRCC), and chromophobe renal cell carcinoma (CRCC).
- Out of 125 patients evaluated, the diagnostic accuracy was highest for CCRCC (87.8%), followed by PRCC (83.3%) and CRCC (73.7%), with no significant accuracy difference between CEUS and CECT (P>0.05).
- The study found distinct enhancement patterns using CEUS across the different cancer types, suggesting CEUS
Introduction: This study aims to evaluate the predictive value of color Doppler ultrasound for the diagnosis of aberrant right subclavian artery (ARSA) with a co-occurring non-recurrent right laryngeal nerve (NRLN).
Material And Methods: In the present study, 58 patients with ARSA (ARSA group) and 1,280 patients without ARSA (controls) were diagnosed by ultrasonography. In addition, 32 patients with ARSA (ARSA operation group) and controls underwent thyroidectomy with surgical exploration with or without NRLN.
Objective: To compare the impact of unilateral acute testicular ischemia on the hemodynamics and histology of the contralateral testis of the rabbits under consistent anesthesia with that of the rabbits in the conscious state.
Methods: Forty-two healthy male white rabbits were randomly divided into an anesthetic group (Group A) to receive injection of sodium pentobarbital (PS) and a non-anesthetic group (Group B), each including a control group of 5 animals (A0 and B0), an incomplete testicular ischemia group of 8 (A1 and B1), and a complete testicular ischemia group of 8 (A2 and B2). Testicular ischemia models were constructed by color Doppler ultrasonography.

Objective: To investigate the protective effect of ischemic postconditioning (IP) against different degrees of testicular ischemia-reperfusion (IR) injury in rabbits.
Methods: Forty-two white male rabbits were equally randomized into 7 groups: a control, 3 IR (R1, R2 and R3), and 3 IP (P1, P2 and P3) groups. Testicular models of different degrees of ischemia were established in the IR and IP groups.
Objective: To investigate the correlation of the ultrasonographic appearance of different degrees of experimentally induced acute unilateral testicular ischemia with the protective effect of allopurinol.
Methods: Forty-two male white rabbits were equally randomized into 7 groups: sham-operation control, ischemic A, B and C, and treatment D, E and F. Models of different degrees of unilateral testicular ischemia were established in the ischemic and treatment groups under the dynamic observation by color Doppler ultrasound.
Objective: To discuss the correlation between sonographic appearance of different degrees of acute unilateral testicular ischemia and histological changes of the testis after reperfusion.
Methods: Thirty-two male rabbits were equally divided into a control (sham operation) group and 3 ischemia groups. Unilateral testicular ischemia models were established under the color Doppler ultrasound (CDU) observation and allocated according to different degrees of ischemia to Group A (with homogeneous echoes and slightly decreased flow signals), B (with heterogeneous echoes and obviously decreased flow signals) and C (with radial or small-shredded low echoes and absence of flow signals).
Objective: To discuss the correlation of ultrasonographic grading of varicocele (VC) with the changes of seminal parameters after varicocelectomy.
Methods: A total of 129 cases of VC were diagnosed by scrotal color Doppler ultrasonography (CDU) and graded into 3 groups: VC I, VC II and VC III, according to three different grading indexes: the regurgitant volume of pampiniform plexus veins (PPV), the maximum diameter of PPV and the combination of the regurgitant volume and the maximum diameter of PPV. All the patients underwent high ligation of the spermatic vein and semen analysis was performed before and after varicocelectomy according to the WHO guidelines.
