Quantitative Imaging in Medicine and Surgery

BackgroundShear wave elastography (SWE) can evaluate cervical function by measuring the stiffness of the cervix of pregnant women. The aim of this study was to investigate the value of transvaginal ultrasound real-time SWE for assessing cer…

BackgroundUterine leiomyoma is a prevalent benign tumor arising from the smooth muscle cells of the uterine wall, profoundly affecting women's reproductive health and overall quality of life. Despite extensive studies on hormonal and molecu…

BackgroundGynecological acute abdomen is a common emergency condition requiring rapid and accurate diagnostic imaging to guide timely clinical decision-making. This study evaluated the diagnostic value of transabdominal ultrasound (TA-US), …

BackgroundPelvic floor myofascial pain (PFMP) is an important yet often overlooked cause of chronic pelvic pain (CPP). The currently available diagnostic methods are limited due to issues such as insufficient efficacy and difficulties in pr…

BackgroundEndometrial receptivity (ER) is critical for embryo implantation, and its impairment is a major contributor to infertility. Current ER evaluation methods are invasive and poorly standardized. Shear wave elastography (SWE) offers a…

BackgroundInfertility affects many couples worldwide, and the accurate assessment of endometrial receptivity (ER) is critical. However, conventional ultrasound has limited predictive value. Multiparameter quantitative ultrasound is a promis…

BackgroundNumerous studies have suggested that assessing endometrial and subendometrial blood flow can contribute to the evaluation of endometrial receptivity. However, there remains a lack of unified expert consensus regarding the assessme…

BackgroundEndometrial fibrosis can disrupt the uterine junctional zone and lead to infertility. Accurate and noninvasive evaluation of junctional zone alterations is important to clinical treatment. Although conventional T2-weighted imaging…

BackgroundRobert's uterus (also known as Robert's uterine malformation) is a rare congenital anomaly characterized by a complete, asymmetric muscular septum that divides the uterine cavity into two separate hemi-cavities, one of which is of…

BackgroundAccurate diagnosis of rectal and perirectal lesions remains challenging, particularly for submucosal, necrotic, or anatomically complex masses where conventional endoscopic forceps biopsy (EFB) often yields insufficient tissue. Tr…

BackgroundThe Ovarian-Adnexal Reporting and Data System (O-RADS) ultrasound (US) is a standardized tool for assessing adult adnexal lesions, but its performance in the pediatric population has not been fully validated. This study aimed to v…

BackgroundPelvic floor myofascial pain (MFP) is a common yet often underdiagnosed condition, and the clinical significance of ultrasonographically identified myofascial trigger points (MTrPs) remains insufficiently understood. The aim of th…

BACKGROUND: Ultrasound-guided anhydrous ethanol sclerotherapy (UGAES) is an effective treatment option for ovarian endometrioma-related pain and infertility. However, its use is limited by the fact that alcohol can sometimes cause unbearabl…

BackgroundCesarean scar pregnancy (CSP) is a special form of ectopic pregnancy that lacks specific clinical manifestations. Artificially induced abortion may lead to severe complications such as massive bleeding and even uterine rupture, po…

BackgroundOvarian sex cord-stromal tumors (OSCSTs) are a rare and heterogeneous group of ovarian neoplasms, encompassing various subtypes such as ovarian thecoma, fibroma (including cellular fibroma), and ovarian granulosa cell tumors (OGCT…

BACKGROUND: Adenomyosis is a prevalent gynecological condition among women of reproductive age and is commonly associated with heavy menstrual bleeding, severe dysmenorrhea, and infertility. These symptoms impose a substantial burden on bot…

BACKGROUND: Cryoablation is a minimally invasive treatment, with limited research on uterine diseases. This paper provides a review of image-guided cryoablation for the treatment of gynecologic diseases, such as uterine myoma, abdominal wal…

BackgroundComprehensive sonographic evaluation of pre- and postmenopausal women with abnormal uterine bleeding is essential for accurate diagnosis and the optimization of curative outcomes for endometrial malignancy. Microvascular flow imag…

BackgroundPhysiologic hydronephrosis in pregnancy is usually asymptomatic, however, definitions of symptomatic hydronephrosis vary, pain being the only criterion in some cases. We found no literature validating physiologic hydronephrosis as…

BACKGROUND: Shear wave elastography (SWE) can be used to detect the stiffness of the myometrium and lesion of the uterus, shear wave dispersion (SWD) can be used to detect the viscoelasticity, and magnetic resonance imaging (MRI) can be use…

BackgroundIntravenous leiomyomatosis (IVL) is a rare benign smooth muscle tumor, for which the ultrasound features and diagnostic value have rarely been reported due to its infrequent presentation. This study aimed to analyze ultrasonograph…

BackgroundHigh rates of infertility and pregnancy complications in patients with intrauterine adhesion (IUA) even after surgical repair may be associated with poor endometrial receptivity (ER). In our previous study, we found that changes o…

BACKGROUND: Adenomyosis is characterized by ectopic endometrial tissue, which causes dysmenorrhea, menstruation, and infertility, significantly impairing quality of life. Current treatments-including medications, surgery, and interventional…
