Comparing the Diagnostic Power of Chest CT Scan and RT-PCR in Diagnosis of COVID-19
Background and purpose: Proper diagnosis of patients with COVID-19 is one of the challenges in medical centers. RT-PCR is the standard and reference test in diagnosis of patients with COVID-19. This study aimed at accelerating the correct diagnosis of COVID-19 and the diagnostic power of chest CT scan and RT-PCR. Materials and methods: This study was performed in 569 patients with COVID-19 adm...
متن کاملInsufficient evidence for chest CT scan in TB outbreak investigation.
Correspondence result that FRC TLC and RV TLC ratios are disproportionately elevated. We have speculated about the infl uence of erroneously elevated volume ratios on the interpretation of published COPD outcome studies. For example, Fessler et al 2 developed a model in which plethysmographically measured RV TLC ratios predicted improvement in FEV 1 following lung volume reduction surgery (LVRS...
متن کاملUsefulness of nanoparticles to making shield and protection of sensitive organs in chest CT scan test
Introduction: Recently, the use of nanoparticles has increased for many purpose in medicine. One of these is using the nano particles in shields structure to protect sensitive organs such as breast which placed inside the field of chest CT scan and receives high dose. The aim of this study was the use of nano Bi2O3 to making shield for protection breast in chest CT examination ...
متن کاملClinical Value of Low Dose CT- Scan in Pediatric Chest Diseases: Adequacy Assessment
Background Radiation dose about 400 times that of standard thoracic computed tomography (CT) in comparison with chest X- ray resulting in different approaches to decrease radiation dose have been established in the last few years to prevent possible side effects especially in children, such as low dose protocols. The aim of this study was assessment of clinical v...
متن کاملAnteroposterior chest radiograph vs. chest CT scan in early detection of pneumothorax in trauma patients
Pneumothorax is a common complication following blunt chest wall trauma. In these patients, because of the restrictions regarding immobilization of the cervical spine, Anteroposterior (AP) chest radiograph is usually the most feasible initial study which is not as sensitive as the erect chest X-ray or CT chest for detection of a pneumothorax. We will present 3 case reports which serve for bette...
