Abstract
This study aimed at discussing deep learning-based dual-source spiral computed tomography (DSCT) image in the evaluation of the efficacy of statins in the treatment of coronary artery plaque. A convolutional neural network (CNN) algorithm was proposed in this study. On this basis, the model was improved, the Res-Net network was applied to reconstruct the computed tomography (CT) image, and the deep learning network model Mask R-CNN was constructed to enhance the ability of image reconstruction. Then, 80 patients with coronary artery disease who were treated in hospital were selected as the research objects and divided into a control group (n = 40) and an observation group (n = 40). There were 21 male patients and 19 female patients in the control group, with an average age of 52 ± 3.2 years; there were 24 male patients and 16 female patients in the observation group, with an average age of 51 ± 2.4 years. The observation group was reconstructed with the constructed model, and patients in the control group received traditional CT. The interval between two examinations was 6–12 months, with an average interval of 8 ± 1.78 months. During the interval, all patients received conservative treatment mainly with atorvastatin. The general data of the two groups were comparable without statistical significance ( P > 0.05 ). A network model was constructed to measure the coronary plaque and vascular volume of the patients, and the images were reconstructed on the Res-Net network. The loss value of Res-Net network was stable at the lowest level around 0.02, showing a very fast effect in the training process. After statin treatment, the vascular volume and coronary plaque volume of the patients were decreased obviously ( P < 0.05 ). The average time spent in the network model was 1.20 seconds. The average time spent in the measurement of each disc by doctors A, B, and C was 186 seconds, 158 seconds, and 142 seconds, respectively. The construction of network model markedly improved the speed of CT image diagnosis and treatment. In conclusion, the Res-Net network model proposed in this study had certain feasibility and effectiveness for dual-source CT (DSCT) image segmentation and could effectively improve the clinical information evaluation of CT images from patients with coronary artery disease, which had important reference value for the development of intelligent medical equipment. It could provide a new diagnostic method for clinical prediction and diagnosis of coronary artery disease (CAD).
Highlights
80 patients with coronary heart disease were selected as the research objects, who had undergone two multislice spiral computed tomography (CT) (MSCT) coronary artery imaging examinations and were treated in hospital from December 2017 to December 2020. is study was approved by the Medical Ethics Committee of the hospital, and the patients and their family members understood the situation of the study and signed the informed consent forms
Training and Verification of the Mask R-convolutional neural network (CNN) Model. e dataset was adopted to train and analyze the network model, and the results are shown in Figure 8. e other parts of the network were fixed first, the network iteratively learned 60 epochs, the initial learning rate was divided by 10, and the open network layer was used to learn 100 epochs
0 Control group the vascular volume and plaque volume of patients were measured before and after treatment, and the results showed that statins steeply reduced the plaque volume and vascular volume, indicating that the drugs had a reliable curative effect
Summary
80 patients with coronary heart disease were selected as the research objects, who had undergone two multislice spiral CT (MSCT) coronary artery imaging examinations and were treated in hospital from December 2017 to December 2020. E criteria for exclusion were defined to include patients who were combined with vascular dementia, Lewy body dementia, and other mental illnesses; had had coronary artery stent or bypass grafting; had major functional insufficiency; and suffered from diabetes and should stop the biguanide drugs for 48 hours before the examination. All the research objects were randomly divided into the control group (n 40) and the observation group (n 40). Patients in the control group received traditional CT images. The Boston ultrasound diagnostic instrument and the ultrasound imaging system were used for detection, and the vascular and plaque volumes were recorded
