Abstract:
E-cigarette or vaping, product associated lung injury is a rampant public health issue with a total of 2807 reported hospitalized patients in the United States as of February 18, 2020. Limited data, non-specific symptoms, non-responsiveness to antibiotics, and the lack of a specific biomarker, make it a diagnosis of exclusion. Overlap of clinical and imaging findings with other ongoing respiratory illness (MERS, SARS and COVID-19) poses a challenge in accurate diagnosis. We compiled 3 cases of patients hospitalized with confirmed vaping-associated lung injury and analyzed their imaging patterns, which revealed bilateral consolidation, ground-glass opacities and pleural effusions. We also reviewed the available literature on pathophysiology, imaging findings of EVALI and other respiratory illness.

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...

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...

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...
