In part-solid GGNs, higher kurtosis and smaller mass are significant differentiators of preinvasive lesions from IPAs, and preinvasive lesions can be accurately differentiated from IPAs by using computerized texture analysis. Online supplemental material is available for this article.

sOHSS can occur by at least three different pathophysiological mechanisms.

Purpose To determine whether fat‐signal‐fraction (FF) map using a modified Dixon sequence could help differentiate benign from malignant bone lesions. Materials and Methods Spine magnetic resonance images (MRIs) of 120 consecutive patients were studied by using a 3T MRI with standard T 1 ‐weighted image ( T 1 WI) and modified‐Dixon sequence for FF measurement. There were three groups: a control group ( n = 51) with normal vertebrae; a benign group ( n = 40) with focal red marrow deposition, Schm

BACKGROUND: Myolysis is one of the procedures that is claimed to provide significant improvement in myoma status without hysterectomy. Myolysis procedures have been generally performed via laparoscopy, and there are limited data on transvaginal radiofrequency (RF) myolysis. This study investigated the feasibility, efficacy and safety of transvaginal ultrasound-guided RF myolysis. METHODS: Transvaginal ultrasound-guided RF myolysis was performed on 69 premenopausal women with symptomatic uterine

Our results suggest that luteal phase progesterone supplementation decreases miscarriage rate and improves live birth rate in natural FTET cycles.

<b>OBJECTIVE.</b> The objective of our study was to compare the sensitivity of a deep learning (DL) algorithm with the assessments by radiologists in diagnosing osteonecrosis of the femoral head (ONFH) using digital radiography. <b>MATERIALS AND METHODS.</b> We performed a two-center, retrospective, noninferiority study of consecutive patients (≥ 16 years old) with a diagnosis of ONFH based on MR images. We investigated the following four datasets of unilaterally cropped hip anteroposterior radi

Ultrasonography (US) has been considered image of choice for gallbladder (GB) polyp, however, it had limitations in differentiating between nonneoplastic polyps and neoplastic polyps. We developed and investigated the usefulness of a deep learning-based decision support system (DL-DSS) for the differential diagnosis of GB polyps on US. We retrospectively collected 535 patients, and they were divided into the development dataset (n = 437) and test dataset (n = 98). The binary classification convo

PROBLEM: Antiphospholipid antibodies (APA) are thought to be involved in recurrent pregnancy loss. Therefore, we investigated the impact of APA on pregnancy outcome in women undergoing in vitro fertilization and embryo transfer (IVF-ET). METHOD OF STUDY: Blood samples taken from 54 Korean women referred for IVF were tested for the presence of APA, anticardiolipin antibody IgG and IgM and lupus anticoagulant. The standard gonadotropin-releasing hormone agonist long protocol was used for ovarian s

AIMS: This study compared the clinical outcome of patients undergoing outside-in transobturator tape (TOT) or inside-out transobturator tape (TVT-O) procedures for female stress urinary incontinence (SUI). METHODS: The study examined the medical records of 615 patients who underwent TOT (376 patients) or TVT-O (239 patients) for SUI, and compared patient characteristics, operation time, duration of hospital stay, cure rates, and complication rates, by conducting a 1-year follow-up survey. RESULT

These preliminary results indicate that benign versus malignant gallbladder polyps might exhibit different spectral patterns on multispectral PA imaging.
