Contrast-enhanced magnetic resonance image segmentation based on improved U-Net and Inception-ResNet in the diagnosis of spinal metastases.

Objective: The objective of this study was to investigate the use of contrast-enhanced magnetic resonance imaging (CE-MRI) combined with radiomics and deep learning technology for the identification of spinal metastases and primary malignant spinal bone tumor.

Methods: The region growing algorithm was utilized to segment the lesions, and two parameters were defined based on the region of interest (ROI). Deep learning algorithms were employed: improved U-Net, which utilized CE-MRI parameter maps as input, and used 10 layers of CE images as input.

Automated meniscus segmentation and tear detection of knee MRI with a 3D mask-RCNN.

Background: The diagnostic results of magnetic resonance imaging (MRI) are essential references for arthroscopy as an invasive procedure. A deviation between medical imaging diagnosis and arthroscopy results may cause irreversible damage to patients and lead to excessive medical treatment. To improve the accurate diagnosis of meniscus injury, it is urgent to develop auxiliary diagnosis algorithms to improve the accuracy of radiological diagnosis.

Treatment of irreducible femoral intertrochanteric fractures using a wire-guided device.

Purpose: Treatment of irreducible femoral intertrochanteric fractures often requires open reduction. However, the technique unavoidably causes patients to suffer greater trauma. As such, minimally invasive techniques should be employed to reduce the surgical-related trauma on these patients and maintain a stable reduction of the fractures.

Effect of Melatonin and Calmodulin in an Idiopathic Scoliosis Model.

[Case-control study on suture-assisted locking plate for the treatment of proximal humeral fractures in elderly].

Objective: To explore clinical effects of suturing-assisted locking plate in treating elderly proximal humeral fractures.

Methods: From January 2005 to January 2013, 55 elderly patients with three- and four-part fractures of proximal humeral fractures were divided into treatment group and control group. In treatment group, there were 31 patients including 12 males, and 19 females aged from 65 to 85 with an average of (74.

[Anterior operative approach for the treatment of old inferior-cervical fracture-dislocation].

Objective: To explore the choice of operative approach for old inferior-cervical fracture-dislocation and analyze the clinical effects of anterior operative approach.

Methods: From January 2003 to May 2010, 17 patients with inferior-cervical fracture-dislocation delayed for more than 4 weeks were treated with continued closed skull traction and anterior decompression, bone graft and internal fixation with steel plate. Among the patients, 11 patients were male and 6 patients were female with an average age of 41 years (ranged from 24 to 56 years).
