Abstract:
The present study aimed to evaluate the radiological findings of coronavirus patients who had positive computed tomography of the lung following real-time reverse transcriptase-polymerase chain reaction testing. The data of 1727 patients who had reverse-transcriptase-polymerase chain reaction (RT-PCR) testing between May 2020 and August 2021 and had thoracic computed tomography (CT) on Days 7th to 8th were analyzed retrospectively. The Radiological Society of North America's recommended reporting system was used to categorize CT findings. Of the 1727 patients who underwent RT-PCR testing, there were 1417 patients with positive CT results. Of these 1417 patients, 679 (47.9%) were female. When patients with high blood values were evaluated, the number of CT-positive patients was significantly higher than CT-negative patients (P < .05). The number of patients with low lymphocyte and albumin values was significantly higher (P < .05). In 75.7% of those who had positive CT results, the PCR result was positive. Thoracic CT is a critical diagnostic tool in Coronavirus Disease 2019 patients with RT-PCR negative. It also depicts the progression of lung involvement in RT-PCR-positive patients. Performing it late in the disease's progression may increase the risk of contracting the disease.

Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
