The use of CTM CT scans for outpatients (OCTCs) is completely consistent with clinical knowledge and global practices. It is also an effective tool for diagnosing COVID-19 coronavirus infection
In April, Moscow clinics had noticed an increase in the number of patients suspected of COVID-19, adding those in critical condition. There is a desire to use mass detection techniques to facilitate early diagnosis of COVID-19 infection.
To do this, Moscow’s outpatient clinics have been changed to 48 OCTC. In this way, the clinics have joined the fight opposite the coronavirus so that the remedy can be initiated as soon as possible.
To reduce the hospital burden, it was suggested that patients with mild symptoms be isolated at home.
General practitioners referred patients to a series of tests, such as PCR (chain reaction through polymerosis), blood tests to evaluate symptoms of inflammation, pulse oximetry to evaluate blood oxygen saturation and ECG (electrocardiography). Symptomatic patients were referred for CT exams.
Early diagnosis has contributed to the immediate isolation of asymptomatic carriers and greater adaptation of therapeutic regimens to critical patients.
In total, more than 175,000 CT scans have been performed on CT scans to date. However, there was never any doubt about sending each patient suspected of COVID-19 for a CT scan.
In order to diagnose clinical symptoms, doctors must first have access to reliable and targeted data. Worldwide, this component is called a learning curve. “Each country has reacted differently to the emergence of the new coronavirus infection.”
The UK has relied on GPS, South Korea has deployed cellular laboratories in car parks, while China has established stadium hospitals to house asymptomatic patients. “
“Doctors were unaware of the etiology, pathogenesis, clinical symptoms, diagnosis or remedy of the new coronavirus infection,” said Sergey Morozov, a leading specialist in radiation and instrumental diagnosis from Moscow and the Central Federal District of Russia, and director of Moscow. Diagnostic and Telemedicine Center.
The World Health Organization (WHO) has developed its diagnostic rules based on the two emergency medical codes of ICD-10. The first code U07.1 required confirmation of coronavirus disease by laboratory testing. Under the time code U07.2, the diagnosis is intended to be based on clinical symptoms.
All patients with coronavirus symptoms and positive PCR tests have ct scans of their lungs “
However, to monitor lung settings, doctors use another classification that divides patients into 4 groups: 25%; 25-50%; 50-75%; 75-100% lung damage. The broken domain can be decided through X-rays and CT scans.
99% of patients with severe lung injury (CT 3 50-75%) (CT four 75-100%) are treated in a hospital. Patients with mild to moderate lung injuries (CT 2 25-50%) are referred to the hospital in cases of hypoxemia.
The Moscow Diagnostic and Telemedicine Center, with leading experts in radiological diagnostics, anesthesiology, intensive care and infectious diseases, has published rules for COVID-19 radiation diagnosis.
The document includes a detailed description of the semiotics of viral lung lesions, a differential diagnosis and a protocol of interpretation of chest CT. The standards have been developed to assist radiation specialists and are intended for the protection and effectiveness of diagnostic units.
The instrumental, laboratory and radiological diagnostic box uses the concept of diagnostic accuracy to reveal the typical symptoms of conditions. This is also true for COVID-19.
The accuracy of computed tomography strategies for the diagnosis of coronavirus infection amounts to 97-98% and is based on 3 indicators: sensitivity, specificity and dominance under the curve of the operational characteristics of the receiver (the ROC curve) International studies offer extensive evidence for the sensitivity of computed tomography: 98% (Radiology, Fang et al.), 97.2% (European Journal of Radiology of Long Radiology Array: 98% (Radiology, Fang et al.), 97.2% (European Journal of Radiology of Long Radiology Array: 98% (Radiology, Fang et al.), 97.2% (European Journal of Radiology of Long Radiology Array) , et al.), 97% (Radiology, Ai et al., Caruso et al.), 67-97% (Radiology, Bai et al.), 80% (Invest Radiol, Li et al.) Computed tomography is highly specific: 93-100% (Radiology, Bai et al.), 82.8% (Invest Radiol, Li et al. Array) The domain under curve H and D is 0.77 to 0.92 (Japanese Journal of Radiology, Himoto, et al.)
According to publications from China, Italy and Japan, 91 to 100 percent of patients with positive PCR effects have typical CT effects such as frosted glass opacity, 93% of patients have multilobular lesions and subsequent injuries, while bilateral involvement has been recorded in 80 to 91% of patients.
This is a clinical trend of coronavirus pneumonia (Radiology, Caruso D et al., Bai HX et al.; Japanese Journal of Radiology, Himoto Y, et al.; European Radiology, Ye Z et al., Canadian Association of Radiologists Journal, Dai et al.)
The CT test is for patients with typical clinical and epidemiological symptoms, even if they have negative PCR control effects (Radiology: Fang Y et al., Ai T et al.) The CT effects of 60-93% in COVID-19 appear before PCR control is positive (Radiology: Ai T et al.) Computed tomography is capable of presenting typical abnormalities in 83% of the asymptomatic disease (subclinical) phase (Inui S et al.)
It should be noted that, regardless of the condition, diagnosis is never made on the basis of images, tools or laboratory results.
In other words, CT scans are a diagnostic tool rather than a remedy method. Health organizations around the world are taking full advantage of COVID’s outpatient and home remedy.
The US formula was largely based on home care with remote patient follow-up: (Reviews in cardiovascular medicine, McCullough et al.), China (Investigative Radiology, Li et al.), Italy (Giornale Italiano di Cardiologia, Tarantini et al.; Head NeckArray Vaira et al.), United Kingdom (Clin Radiol, Nair A.), Canada (CMAJ, Glauser), India (Indian Journal of Pediatrics, Singhal T.), South African Family Practice (Mash) in the Other hand, South Korea has focused on the creation of committed outpatient centers (Journal of Korean Medical Science, Park et al.)
