A fully automated rib fracture detection system on chest CT images and its impact on radiologist performance.

Objective: To compare rib fracture detection and classification by radiologists using CT images with and without a deep learning model.

Materials And Methods: A total of 8529 chest CT images were collected from multiple hospitals for training the deep learning model. The test dataset included 300 chest CT images acquired using a single CT scanner.

[Effects of cultivation patterns on wheat yield and soil fertility in dryland].

A field experiment was conducted to examine the effects of plastic film mulching (PM), straw retention (SR), and planting green manure (GM) on winter wheat grain yield and soil fertility. The results showed that PM did not have consistently positive effect on the grain yield, when compared to the traditional patterns (TP). No difference of average grain yield was observed between them over three years.

[Effects of cultivation patterns on wheat yield and grain nutrient concentration in dryland].

A field experiment was conducted to examine the effects of plastic film mulching (PM), straw retention (SR) and planting green manure (GM) on grain yield and nutrient concentrations of winter wheat. Compared to the traditional pattern (TP), plastic film mulching showed no significant effect on the average yield over the three years but increased the average phosphorus (P) uptake and concentration in grain by 8.4% and 13.

Quantitative evaluation of knee cartilage and meniscus destruction in patients with rheumatoid arthritis using T1ρ and T2 mapping.

Objective: To calculate T1ρ and T2 values of articular cartilage and menisci in knee joints of patients with RA, and compare the values between RA patients and healthy volunteers, to gain insight into the pathogenesis of cartilage and meniscus degradation in patients with RA.

Materials And Methods: Nine patients with RA and knee joints symptoms were enrolled in the study, twenty healthy volunteers without knee joint diseases were included as controls. Sagittal fat-saturated T1ρ and T2 mapping images were obtained on a 3T MR scanner (GE750, GE Healthcare, Waukesha, WI), using a dedicated 8-channel knee coil.

Mast cells or not? - CD117 positive cells in esophageal leiomyoma.

The presence of CD117 positive cells in esophageal leiomyoma may lead to a misdiagnosis of GIST. We reviewed 46 esophageal tumors which were smooth muscle tumors or GIST. Based on morphology, immunohistochemistry and mutation analysis, there were 44 (95.

Role of CT perfusion imaging in evaluating the effects of multiple burr hole surgery on adult ischemic Moyamoya disease.

Introduction: To evaluate the effects of the multiple burr hole (MBH) revascularization on ischemic type adult Moyamoya disease (MMD) by computed tomography perfusion (CTP).

Methods: Eighty-six ischemic MMD patients received CTP 1 week before and 3 weeks after MBH operation. Fifty-seven patients received it again at 6 month and underwent digital subtraction angiography (DSA) and mRS follow-up.

Anterior versus posterior approach for treatment of thoracolumbar burst fractures: a meta-analysis.

Purpose: To critically review and summarize the literature comparing the results of surgery via an anterior approach and that via a posterior approach for the treatment of thoracolumbar burst fractures to identify the better approach.

Methods: In this meta-analysis, we conducted electronic searches of MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and other databases using the search terms "thoracolumbar fractures", "anterior", "posterior", "controlled clinical trials". Relevant journals or conference proceedings were also searched manually.
