Objective: Lymphovascular invasion (LVI) is critical for the effective treatment and prognosis of breast cancer (BC). This study aimed to investigate the value of eight machine learning models based on MRI radiomic features for the preoperative prediction of LVI status in BC.
Methods: A total of 454 patients with BC with known LVI status who underwent breast MRI were enrolled and randomly assigned to the training and validation sets at a ratio of 7:3.
To construct a nomogram based on clinical factors and paraspinal muscle features to predict vertebral fractures occurring after acute osteoporotic vertebral compression fracture (OVCF). We retrospectively enrolled 307 patients with acute OVCF between January 2013 and August 2022, and performed magnetic resonance imaging of the L3/4 and L4/5 intervertebral discs (IVDs) to estimate the cross-sectional area (CSA) and degree of fatty infiltration (FI) of the paraspinal muscles. We also collected clinical and radiographic data.

Meanwhile, tumor-derived EVs can carry long non-coding RNAs to activate pro-angiogenic signaling in endothelial cells. Here, we investigated the role of long non-coding RNA MCM3AP-AS1 carried by cervical cancer (CC) cell-derived EVs in the angiogenesis and the resultant tumor growth in CC, as well as the potential molecular mechanisms.

However, 18F-FDG PET/MRI may be superior to PET/CT for the diagnosis of distant metastases in patients with advanced-stage. Therefore, it is timely and important to systematically determine the diagnostic accuracy of 18F-FDG PET/MRI compared with that of 18F-FDG PET/CT for the diagnosis of distant metastases.

The present study assessed correlations between preoperative breast MRI, clinical features, and LVI in patients with invasive ductal carcinoma (IDC) and identified risk factors based on these correlation factors.
Materials And Methods: Patients confirmed with IDC between 01/2012 and 12/2021 were retrospectively reviewed at our hospital.
To investigate overuse wrist injuries in adolescent divers using magnetic resonance imaging (MRI). The bilateral wrists (76 wrists) of 38 professional divers were examined by MRI; 42 wrists with pain were placed in the symptomatic group, and 34 wrists without pain were placed in the asymptomatic group. Two experienced radiologists assessed the wrist injuries.

Methods: Patients who were treated with PVP for single vertebral compression fractures (VCFs) and met this study's inclusion criteria were retrospectively reviewed from January 2012 to January 2019. The follow-up period was at least 2 years.

Methods: Twelve healthy athletes (24 patellar tendons) and 31 volleyball athletes with PT (48 tendons) were included. All were examined by US and received VISA-P scores before the start of the study.
Objective: To investigate the effects of long-term diving on the morphology and growth of the distal radial epiphyseal plate in young divers.
Study Design: Cohort study.
Setting: Guangzhou Sport University.
Objective: To explore the different influences of walking, running and stair activity on knee articular cartilage with T1 rho and T2 mapping sequences.
Materials And Methods: MRI (3.0-T) scans of the right knee were performed in twenty-three young healthy adults immediately after 30 minutes of rest, walking, running and stair activity respectively.
