Objective: To analyze the cases of thyroid carcinoma with special sonographic features, so as to increase the accuracy of sonographic diagnosis for thyroid carcinoma.
Methods: The sonographic characteristics of 9 patients with special sonographic appearance were analyzed. According to the sonographic features, they were divided into two kinds: 8 cases suffered from thyroid diffuse malignant lesions, and one case showed cystic lesion sticking out of the thyroid. The sonographic appearance of gray scale and color Doppler characteristics of the lesions were recorded.
Result: In the first kind of lesions, the dimensional ultrasound appearance of gray scale had an apparent feature, however, its color Doppler characteristics had no apparent feature, and all of the 8 cases were diagnosed correctly by ultrasound. In the second kind of lesion, the sonographic appearance of gray scale and color Doppler had no special features, so the case was diagnosed as benign disease wrongly by ultrasound.
Conclusion: The first kind of lesions has apparent sonographic features, sonographic diagnosis can serve as the first choice. However, the second kind of lesion had no apparent sonographic feature.

Introduction: To correlate the direct and indirect morphological uterus sonographic assessment (MUSA) features of adenomyosis with clinical symptoms severity.
Material And Methods: This observational prospective study was conducted at a tertiary care institute from April 2023 to March 2024, involving 254 women aged 18 to 45 years with a regular menstrual cycle and ultrasound-confirmed diagnosis of adenomyosis. Detailed clinicodemographic data were collected, including symptoms such as painful menses, heavy menstrual bleeding (HMB), chronic pelvic pain (CPP), and bowel/bladder symptoms.
Advancements in Ultrasound Diagnosis of Superficial Endometriosis: Current Challenges and Emerging Techniques.
Gynecol Obstet Invest
January 2025
Background: Endometriosis is a chronic disease characterized by endometrial-like tissue outside the uterus. Superficial endometriosis (SE) is the most prevalent form, yet it remains underdiagnosed due to subtle clinical and imaging presentations. Traditionally, diagnosis relies on laparoscopy, which is relatively invasive and often contributes to diagnostic delay.

To determine the cancer risk in thyroid nodules using ACR TI-RADS. A retrospective analysis of all thyroid biopsies was performed over a 3-year period (2021 to 2023). Variables including gender, age, history of thyroid cancer or neck irradiation, nodule size and location, TR level, and sonographic features such as punctate echogenic foci (PEF), a very hypoechoic appearance, taller-than-wide shape, and suspected extrathyroidal extension were analyzed.

Article Synopsis
- Retroperitoneal nerve sheath tumors are rare, and distinguishing between benign and malignant types is crucial for treating patients effectively.
- A study analyzed 49 patients with benign tumors using ultrasound imaging, applying Adler's grading system to assess tumor characteristics and perform statistical analyses.
- The findings highlight key differences between benign and malignant tumors, such as size and shape, with a maximum diameter of 9.9 cm being a significant indicator of malignancy, suggesting that ultrasonography can enhance diagnostic accuracy and inform treatment approaches.
Nomogram for predicting the efficacy of high-intensity focused ultrasound ablation for uterine fibroids based on oxytocin experimentation and ultrasonographic features: a retrospective single-center study.

Article Synopsis
- Developed a nomogram to predict the effectiveness of high-intensity focused ultrasound (HIFU) for treating uterine fibroids by analyzing oxytocin levels and sonographic features of fibroids.
- Conducted a retrospective study of 60 patients, utilizing logistic regression to identify key predictive factors like myoma type, blood flow, and oxytocin classification, resulting in a model assessed using R language.
- The model demonstrated strong predictive ability with an area under the curve of 0.887 and good calibration, suggesting it can effectively guide clinicians in selecting appropriate patients for HIFU treatment.
