Background:
It has been shown that cavitary lesions on CT scans of patients with COVID-19 may be related to their clinical symptoms and mortality rate.
Materials And Methods:
The study population included patients diagnosed with COVID-19 based on RT-PCR results from throat samples or typical clinical and chest CT scan findings who were hospitalized at Sina Hospital in Tehran in 2020 and underwent chest CT scans. Chest CT scans were examined for the severity of pulmonary opacities and the presence, number, size, wall thickness, and distribution of cavitary lung lesions.
Results:
Oxygen saturation was lower in patients with cavitary lesions in the initial state and after treatment than those without cavitation, and a statistically significant relationship was observed (p < 0.05). In terms of gender, a significant correlation was observed, and the prevalence of cavitary lesions was higher in men (p < 0.05). Also, the in-hospital mortality rate was higher in patients with cavitary lesions (p < 0.05).
Conclusion:
Based on our results, the presence of cavitary lung lesions in COVID-19 patients is related to the mortality rate, severity of pulmonary involvement, and patients' gender.

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...
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...

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...
