Acoustic neuroma classification algorithm based on mask region convolution neural network J. Radiat. Res. Appl. Sci. (IF 1.7) Pub Date : 2024-01-14 Xiaojun Li, Cheng Li, Rong Zhou, Lijie Wei, Yanping Wang
Objective Acoustic neuroma has similarities with other intracranial tumors in imaging manifestations and location of incidence, and misdiagnosis often occurs in clinical practice. This paper uses a mask region convolution neural network (Mask RCNN) to classify acoustic neuromas. Methods The T1WI-SE sequence MRI images of 120 patients with acoustic neuroma in our hospital were collected. Based on preprocessing

Chest radiology report generation based on cross-modal multi-scale feature fusion J. Radiat. Res. Appl. Sci. (IF 1.7) Pub Date : 2024-01-13 Yu Pan, Li-Jun Liu, Xiao-Bing Yang, Wei Peng, Qing-Song Huang
Chest radiology imaging plays a crucial role in the early screening, diagnosis, and treatment of chest diseases. The accurate interpretation of radiological images and the automatic generation of radiology reports not only save the doctor's time but also mitigate the risk of errors in diagnosis. The core objective of automatic radiology report generation is to achieve precise mapping of visual features

NeXtResUNet: A neural network for industrial CT image denoising J. Radiat. Res. Appl. Sci. (IF 1.7) Pub Date : 2024-01-10 Guiling Song, Wei Xu, Yu Qin
Image denoising is a critical issue in industrial computed tomography (CT) inspection. Most existing noise reduction algorithms are based on synthetic data, resulting in the loss of fine details, local region distortions, and other problems that arise during application in practical scenarios. As such, a fusion network, combining ConvNeXt, ResNet, and UNet is proposed in this study to address these

Rehabilitation strategies and magnetic resonance imaging techniques for shoulder injuries in sports J. Radiat. Res. Appl. Sci. (IF 1.7) Pub Date : 2024-01-08 Shuang Liu, Bo Cui, ChengPan Liang
Objective Shoulder sleeve injuries are high-risk in men's tennis, with rehabilitation focusing on activating shoulder muscle groups to regain strength. Specific plans use electromyography and isokinetic instruments to compare muscle activity and torque pre- and post-rehabilitation. The goal is to explore training effects on rotator cuff injuries and assess routine MRI and MRI shoulder arthrography
