Application of 64-Slice Spiral CT Imaging Technology Based on Smart Medical Augmented Reality in the Diagnosis of Foreign Bodies in the Respiratory Tract in Children

A foreign body in the respiratory tract is one of the common accidental injuries of children in our country, and is usually an important and serious event. Injuries caused by foreign substances in the respiratory tract seriously threaten the health and life of children in Korea and are a great challenge for parents as well. In the process of diagnosis of foreign bodies in the respiratory tract, there is often missed diagnosis or serious complications. Therefore, this article proposes the application of 64-slice spiral CT imaging technology based on smart medical augmented reality in the diagnosis of foreign bodies in the respiratory tract in order to improve the diagnosis of foreign bodies in the respiratory tract, provide help with treatment to improve the prognosis of foreign bodies in the respiratory tract, and reduce the incidence of foreign bodies in the respiratory tract. In this paper, 36 children underwent a 64-slice spiral CT scan of their lungs, and images were transferred to a workstation for multiplanar reconstruction, minimal density projection, three-dimensional volume reconstruction imaging, and CT virtual endoscopic reconstruction, the location, shape, size, and size of the foreign body in contrast with adjacent structural lesions and lesions seen during surgery. Experiments have shown that the left bronchial granulation accounted for 27.3%, the right bronchial granulation 18.75%, the main tracheal granulation 28.6%; there was no significant difference between the left and right bronchial granulation ( P > 0.05), while the main tracheal granulation and bilateral bronchial granulation there are significant differences between the shape distributions (P < 0.05). This shows that CT imaging technology has enabled more patients to avoid surgical operations and ensure that the spiral computer can bring the greatest benefits to children. A 64-slice spiral CT scan can diagnose foreign bodies in the child’s respiratory tract. The detection rate is high and the diagnostic failure rate is low. The diagnostic rationale provides a reference for early clinical treatment.

Study of estimation of coronary artery calcium by multi-slice spiral CT scan in post myocardial infarction cases

Background: Strong relationship has been demonstrated between the presence of occlusive CAD and coronary artery calcification (CAC) detected at autopsy, fluoroscopy and computed tomography (CT scan). CT scan quantifies the relative burden of CAC deposits as a marker of atherosclerosis. Study explored utility of multi-slice spiral CT scan for detection of CAC in post myocardial infarction cases.Methods: Fifty-one post myocardial infarction cases were enrolled in the study. Detailed clinical history was recorded in every case regarding age, sex, history of risk factors for CAD like systemic hypertension, diabetes mellitus, smoking and family history of CAD. Every case was evaluated for fasting and postprandial blood sugar and fasting lipid profile. Body mass index (BMI) was also calculated. Coronary artery calcium was estimated in each patient by multi -slice spiral CT scan. Conventional angiography was also undertaken in 18 patients. Co-relation of coronary calcium with different age groups, sex, risk factors, electrocardiography and angiography was drawn.Results: Out of 51 cases scanned, 40 cases (78.4%) had detectable CAC. In 30 cases (58.8%), CAC score ranged from 1 to 100 (mild score); 6 cases (11.8%) had score between 101-400 (moderate score) while in 4 cases (7.8%) CAC score was more than 400 (severe score %). For detection of angiographically detectable disease, the sensitivity of multi-slice CT was 100% and the specificity was 33.3%.Conclusions: CAC is a valid measure of atherosclerotic plaque burden and is recommended as a screening tool for demonstrating significant atherosclerosis in susceptible subjects.

Study of coronary artery calcium by multi-slice spiral CT as a tool for high risk cardiovascular screening

Background: Strong relationship has been demonstrated between the presence of occlusive CAD and coronary artery calcification (CAC) detected at autopsy, fluoroscopy and computed tomography (CT scan). CT scan quantifies the relative burden of CAC deposits as a marker of atherosclerosis. We explored utility of multi-slice spiral CT scan for detection of CAC as a tool for screening in asymptomatic high-risk cases above 40 years of age.Methods: Fifty-eight asymptomatic cardiovascular high-risk cases were included as per selection criteria. Detailed clinical history was recorded in every case regarding age, sex, history of risk factors for CAD like systemic hypertension, diabetes mellitus, smoking and family history of CAD. Every case was evaluated for fasting and postprandial blood sugar and fasting lipid profile. Body mass index (BMI) was calculated. An ECG was also recorded. Coronary artery calcium was estimated in each patient by multi -slice spiral CT scan. Fifty age and gender matched consenting participants were enrolled as controls and comparisons drawn.Results: Out of 58 cases scanned, 41 had no detectable CAC by multi-slice CT scan whereas in 17 cases (29.2%), calcium was detected. Mean CAC score was observed to increase as number of risk factors increased.Conclusions: Multi-slice CT scan is a useful tool for detection of coronary artery calcium (CAC) when utilised for high risk screening in older adults having one or more known cardiovascular risk factors.
