Objective: This study investigated methods of evaluating the bone fracture healing process using superb microvascular imaging (SMI; two modes color SMI [cSMI] and monochromeSMI [mSMI]), and shear wave elastography (SWE), relative to X-ray, dual-energy X-ray absorptiometry (DXA), and platelet endothelial cell adhesion molecule 1 (PECAM-1) also know as cluster of differentiation 31 (CD-31) staining in a rabbit model.
Methods: This IACUC-approved study involved eight rabbits that underwent a bilateral fibula osteotomy and were followed for 7 or 21 days (Groups 1 and 2 with 4 rabbits in each). Ultrasound examinations using cSMI, mSMI, and SWE were performed on Days 0, 4, 7, 14, and 21 post-surgery.

Transcranial Doppler is an instrumental ultrasound method capable of providing data on various brain pathologies, in particular, the study of cerebral hemodynamics in stroke, quickly, economically, and with repeatability of the data themselves. However, literature reviews from clinical studies and clinical trials reported that it is an operator-dependent method, and the data can be influenced by external factors, such as noise, which may require greater standardization of the parameters. Artificial intelligence can be utilized on transcranial Doppler to increase the accuracy and precision of the data collected while decreasing operator dependencies.

Department of Ultrasound, China-Japan Friendship Hospital, National Center for Respiratory Medicine, National Clinical Research Center for Respiratory Diseases, Institute of Respiratory Medicine of Chinese Academy of Medical Sciences, Beijing, China.
Objectives: To establish and validate a dual-modal radiomics nomogram from grayscale ultrasound and color doppler flow imaging (CDFI) of cervical lymph nodes (LNs), aiming to improve the diagnostic accuracy of metastatic LNs in differentiated thyroid carcinoma (DTC).
Methods: DTC patients with suspected cervical LNs in two medical centers were retrospectively enrolled. Pathological results were set as gold standard.

Background: The purpose of the current study was to compare the color Doppler findings of uterine arteries and perinatal outcomes in pregnant women with and without previous cesarean section (C/S).
Methods: This cohort study enrolled 308 pregnant women aged 20-35 without underlying diseases, with at least one previous pregnancy and childbirth. The participants were divided into two groups: 154 women without C/S and 154 women with C/S.

Rationale And Objectives: Accurate distinguish malignant from benign renal masses remains a challenge for radiologists. The purpose of this study was to evaluate the value of Color Doppler Flow Imaging (CDFI), MicroFlow Imaging (MFI) and Contrast-enhanced Ultrasound (CEUS) in diagnosing solid renal tumors.
Materials And Methods: A total of 291 patients with 300 solid renal tumors pathologically confirmed were retrospectively analyzed between January 2020 and December 2022.
