Healthcare organizations are increasingly using medical imaging and imaging analytics to improve COVID-19 detection and prevention.
FREMONT, CA: An epidemic of coronavirus infection has started to emerge and spread rapidly worldwide. Due to its low sensitivity, a chest radiograph is not advised as a first-line imaging modality for COVID-19 disease, particularly in the initial stages of infection. Chest CT imaging has been confirmed to be a more dependable, rapid, and practical method for diagnosing COVID-19, and it can evaluate disease severity and track disease progression.
Ultrasound is portable and does not require radiation, so it could be used in critically ill patients to evaluate the cardiorespiratory function, lead mechanical ventilation, and detect deep venous thrombosis and secondary pulmonary thromboembolism.
PET/CT can provide additional information. During the absence of COVID-19 vaccines and medications, timely diagnosis and treatment are critical. As a result, it is essential to benefit from the advantages of various imaging modalities in the fight against COVID-19.
During this pandemic, the most common method for detecting the disease is nucleic acid testing. This efficient method is appropriate for large-scale collective testing, but it is easily interfered with by various factors, making it more challenging to ensure the precision of the test results.
If there is a suspicious item, a lung CT examination is required to diagnose the condition further. In general, CT images depend on radiologists' experience to make decisions, and there is no objective diagnostic standard.
In the diagnosis of COVID-19, a method of combining artificial intelligence and image diagnosis is used.
COVID-19 imaging manifestations typically consist of multiple ground-glass shadows with thickened interlobular or grid shadows. If lesions form, there is a good chance that bronchial inflation and blood vessel thickening will happen. A few patients may also have bronchial tube wall thickening. The lesions are mostly found under the pleura at the lungs' periphery, primarily in the back and lower lungs.
A CT scan can determine the extent of the impact of COVID-19 lesions on the lungs. Previously, some researchers attempted to investigate the degree of involvement of lung lesions using a CT semi-quantitative scoring system. It is now known as the "CT image lung involvement score" method.
The application process of image diagnosis technology in medical diagnosis
Image diagnosis technology is becoming more widely used in medicine as medical technology advances. The advancement of information technology has created a suitable environment that is favorable for imaging technology. The use of informed imaging data to diagnose and analyze the patient's condition is at the heart of medical imaging technology.
