Ultrasound-based scoring system for differential diagnosis of polypoid lesions of the gallbladder.

Background And Aim: Polypoid lesions of the gallbladder may be neoplastic or non-neoplastic. Correct diagnosis would help reduce unnecessary cholecystectomies. This study aimed to determine the predictive value of individual ultrasound characteristics for diagnosis of neoplastic polyps and to build a scoring system based on these characteristics.

Influence of serum prostate-specific antigen (PSA) level, prostate volume, and PSA density on prostate cancer detection with contrast-enhanced sonography using contrast-tuned imaging technology.

Objectives: The purpose of this study was to evaluate the influence of the serum prostate-specific antigen (PSA) level, prostate volume, and PSA density on prostate cancer detection with contrast-enhanced sonography using contrast-tuned imaging technology compared with baseline imaging (combination of grayscale and power Doppler imaging).

Methods: In all, 161 patients were evaluated with grayscale, power Doppler, and contrast-tuned imaging. Biopsy was performed at 10 sites in each patient.

Value of contrast-enhanced sonographic micro flow imaging for prostate cancer detection with t-PSA level of 4-10 ng/mL.

Objectives: To compare the efficiency of contrast-enhanced ultrasonographic micro flow imaging (MFI) with conventional transrectal ultrasound (TRUS) in detecting prostate cancer with serum total prostate-specific antigen (t-PSA) of 4.0-10.0 ng/mL.

Contrast-enhanced ultrasonography with contrast-tuned imaging technology for the detection of prostate cancer: comparison with conventional ultrasonography.

Unlabelled: Study Type - Diagnostic (exploratory cohort) Level of Evidence 2b What's known on the subject? and What does the study add? The present study was to perform contrast-tuned imaging (CnTI) technology to detect prostate cancer and compare the use of CnTI technology for the detection of prostate cancer with conventional ultrasonography. The preliminary data from our study suggested that targeted biopsy of the prostate with CnTI technology could improve the cancer detection and detect higher grade prostate cancers.

Objectives: To perform contrast-enhanced ultrasonography (CEUS) using contrast-tuned imaging (CnTI) technology to detect prostate cancer.

Differential diagnosis of azoospermia and etiologic classification of obstructive azoospermia: role of scrotal and transrectal US.

Purpose: To evaluate the usefulness of scrotal and transrectal ultrasonography (US) in the differential diagnosis of azoospermia and the etiologic classification of obstructive azoospermia.

Materials And Methods: This study was approved by the institutional ethics committee, and all patients provided written informed consent. Between April 2006 and November 2008, 100 infertile men (mean age, 32 years; range, 22-51 years) with azoospermia were evaluated at scrotal and transrectal US, with an emphasis on abnormal US findings of the seminal tract and measurement of testicular volume.
