Using multimodal ultrasound including full-time-series contrast-enhanced ultrasound cines for identifying the nature of thyroid nodules.

Background: Based on the conventional ultrasound images of thyroid nodules, contrast-enhanced ultrasound (CEUS) videos were analyzed to investigate whether CEUS improves the classification accuracy of benign and malignant thyroid nodules using machine learning (ML) radiomics and compared with radiologists.

Materials And Methods: The B-mode ultrasound (B-US), real-time elastography (RTE), color doppler flow images (CDFI) and CEUS cines of patients from two centers were retrospectively gathered. Then, the region of interest (ROI) was delineated to extract the radiomics features.

Predicting non-small-volume central lymph node metastases (>5 or ≥2 mm) preoperatively in cN0 papillary thyroid microcarcinoma without extrathyroidal extension.

The ability to identify patients with aggressive papillary thyroid microcarcinoma (PTMC) from the low-risk patients is critical to planning proper management of PTMC. Lymph node metastases showed association with recurrence and low survival rate, especially in patients with >5 or ≥2 mm metastatic lymph nodes. Therefore, this study aimed to investigate the preoperatively predictive factors of non-small-volume (metastatic lymph nodes >5 or ≥2 mm in size) central lymph node metastases (NSVCLNM) in PTMC patients.

Anatomical localization of normal parathyroid glands before thyroidectomy through ultrasonography reduces postoperative hypoparathyroidism.

Postoperative hypoparathyroidism due to dysfunction of the parathyroid gland is the most common complication after thyroidectomy. Our objective was to introduce the method of anatomical localization of normal parathyroid glands before thyroidectomy through ultrasonography and to evaluate its efficiency. The study group included 52 patients subjected to anatomical localization of the parathyroid gland prethyroidectomy through ultrasonography.

[The value of thyroglobulin measurement in fine-needle aspiration for diagnosis of suspicious lymph nodes in patients with thyroid carcinoma after thyroidectomy].

Objective: To investigate the value of thyroglobulin measurement in ultrasound guided fine-needle aspiration(FNA-Tg)for detecting neck node metastasis in patients with papillary thyroid carcinoma(PTC)after thyroidectomy.

Methods: A total of 128 suspicious metastatic lymph nodes in 112 patients were retrospectively analyzed. Postoperative pathologic results were taken as the gold standard.

[Application value of contrast-enhanced ultrasonography for assessing the high-risk population of hepatic malignant tumor].

Objective: To investigate the clinical value of contrast-enhanced ultrasonography (CEUS) in assessing the high-risk population of hepatic malignant tumor (HMT).

Methods: Three hundred patients with high-risk of HMT were enrolled and examined by CEUS. The clinical data of these patients were collected.

[Sonographic features and diagnostic analysis of breast granulomatous diseases: a report of 32 cases].

Objective: To evaluate the sonographic features of different pathological types of breast granulomatous diseases and analyze the feasibility of ultrasonic diagnosis.

Methods: A total of 32 patients with different pathological types of breast granulomatous diseases were recruited. Their clinical and sonographic findings were retrospectively reviewed.

[Application of fetal echocardiography in detection of fetal arrhythmia and its clinical significance].

Objective: To investigate application of fetal echocardiography in diagnosis of fetal arrhythmia and its clinical significance.

Methods: Fetal echocardiography was performed on 725 fetuses for evaluation of fetal heart structures and arrhythmias. Two-dimensional, M-mode, Color M-mode and pulsed Doppler echocardiography were used.

Comparison study of harmonic imaging (HI) and fundamental imaging (FI) in fetal echocardiography.

Objectives: To directly compare the quality of harmonic imaging (HI) and fundamental imaging (FI) in fetal echocardiography and to determine any differences in image quality between the two modalities.

Methods: Fetal echocardiograms were performed with the use of FI and HI in 58 fetuses, image quality and visualization of left and right atria, left and right ventricles, mitral and tricuspid valves, aortic and pulmonary valves, left and right ventricular outflow tracts were evaluated and compared between FI and HI.

Results: Mean HI scores were higher than mean FI scores (2.
