Faster RCNN‐based detection of cervical spinal cord injury and disc degeneration

Abstract

Magnetic resonance imaging (MRI) can indirectly reflect microscopic changes in lesions on the spinal cord; however, the application of deep learning to MRI to classify and detect lesions for cervical spinal cord diseases has not been sufficiently explored. In this study, we implemented a deep neural network for MRI to detect lesions caused by cervical diseases. We retrospectively reviewed the MRI of 1,500 patients irrespective of whether they had cervical diseases. The patients were treated in our hospital from January 2013 to December 2018. We randomly divided the MRI data into three groups of datasets: disc group (800 datasets), injured group (200 datasets), and normal group (500 datasets). We designed the relevant parameters and used a faster‐region convolutional neural network (Faster R‐CNN) combined with a backbone convolutional feature extractor using the ResNet‐50 and VGG‐16 networks, to detect lesions during MRI. Experimental results showed that the prediction accuracy and speed of Faster R‐CNN with ResNet‐50 and VGG‐16 in detecting and recognizing lesions from a cervical spinal cord MRI were satisfactory. The mean average precisions (mAPs) for Faster R‐CNN with ResNet‐50 and VGG‐16 were 88.6 and 72.3%, respectively, and the testing times was 0.22 and 0.24 s/image, respectively. Faster R‐CNN can identify and detect lesions from cervical MRIs. To some extent, it may aid radiologists and spine surgeons in their diagnoses. The results of our study can provide motivation for future research to combine medical imaging and deep learning.

High-Resolution Computer Tomography Image Features of Lungs for Patients with Type 2 Diabetes under the Faster-Region Recurrent Convolutional Neural Network Algorithm

“…The faster-region convolutional neural network (Faster-RCNN) algorithm is widely used in medical imaging diagnosis. Based on the analysis of a large number of medical images and the extraction of image features, some researches build the Faster-RCNN intelligent recognition model, so as to achieve the goal of efficiently and accurately processing medical imaging data, and overcome the problem of different clinical doctors facing the same diagnostic difference in the same image, reducing the work intensity of imaging work physicians [ 28 , 29 ]. At present, the Faster-RCNN algorithm has achieved satisfactory results in the identification of clinical image feature information of prostate cancer, lung cancer, and rectal lymph nodes [ 30 , 31 ].…”

“…As used in the advanced setting for cervical disease measurement, combined with artificial intelligence (AI), MRI could serve as a precise and non-invasive diagnosis tool for healthy status detection in IVDs. MRI can detect physiological and morphological changes (such as swelling and asymmetry) based on variations in water molecules by measuring alterations in the intensity of tissue signals [ 33 ]. More importantly, diagnosis is a crucial step in treating and controlling soft tissue lesions, and MRI could provide better diagnostic tools when there is uncertainty regarding diagnosis.…”

Deep Learning-Based CT Imaging in Diagnosing Myeloma and Its Prognosis Evaluation

“…In order to realize the intelligent detection of myeloma using CT images, the Faster RCNN model is used to detect the lesion area. The Faster RCNN model mainly consists of two parts, namely, the region proposal network (RPN) and the region convolutional neural network (RCNN) [ 15 ]. The specific image processing steps using this model are as follows: First, the network classification model is used to extract the feature map, and then, the RPN is used to generate the region of interest (RoI), followed by the pooling operation.…”
