Evaluation of the epididymis and measurement of testicular volume with scrotal US are important in distinguishing obstructive azoospermia from nonobstructive azoospermia in infertile men.

There is a difference in NBL scanned at 11-14 weeks' gestation between the Korean and the Caucasian/African-American populations, and so racial adjustment is needed in the evaluation of the fetal nasal bone for current first-trimester screening.

We have provided reference values for the in-utero development of the fetal anal sphincter throughout gestation.

Thickened pedicles with ancillary findings including a whirl sign, a navel sign, and uterine deviation facing thickened pedicles could be helpful for the diagnosis of adnexal torsion.

Sonographic findings of ovarian GCTs included solid and cystic masses, solid masses with a sponge form appearance, and entirely solid masses, and the sonographic findings correlated well with the histopathologic findings.

We have provided reference values for the fetal gall bladder throughout the gestation period in the Korean population.

On the three-vessel view of the fetal heart, the interpretation of the size discrepancy of the great vessels needs to be adjusted according to fetal growth.

The chorionicity of diamniotic twin pregnancies with a single placental mass can be reliably predicted by transvaginal US depiction of the amnion and chorion at 11 to 14 weeks of gestation.

Measurement of the serum beta-hCG level and evaluation of the transvaginal sonographic appearance of tubal pregnancy are helpful for predicting treatment outcomes in women who receive intramuscular methotrexate therapy for tubal pregnancy.

3D US-based virtual cystoscopy may have diagnostic potential in the detection of polypoid bladder tumors.

Our study showed that nasal bone abnormality at 11-14 weeks of gestation had a high association with DS in the Korean population. This suggests that nasal bone assessment can be used to supplement the current first-trimester screening for DS in the Korean population.

Single-phase acquisition may be a better option for CE MRI in women with endometrial cancer than dynamic acquisition.

This study is aimed to explore the performance of texture-based machine learning and image-based deep-learning for enhancing detection of Transitional-zone prostate cancer (TZPCa) in the background of benign prostatic hyperplasia (BPH), using a one-to-one correlation between prostatectomy-based pathologically proven lesion and MRI. Seventy patients confirmed as TZPCa and twenty-nine patients confirmed as BPH without TZPCa by radical prostatectomy. For texture analysis, a radiologist drew the reg

Preoperative diagnosis of borderline ovarian tumors (BOTs) is of increasing concern. This study aimed to determine computed tomography (CT) features in differentiating stage 1 BOTs from stage I malignant epithelial ovarian tumors (MEOTs). A total of 170 ovarian masses (97 BOTs and 73 MEOTs) from 141 consecutive patients who underwent preoperative CT imaging were retrospectively analyzed. Two readers independently and retrospectively reviewed quantitative and qualitative CT features. Multivariate
