Overview
In this session, the application of MRI to assess two important pulmonary topics will be addressed: vaping-associated lung injury and long term pulmonary sequelae of COVID-19 pneumonia.




Target Audience
Physicians and researchers interested in the development and application of advanced MRI methods to assess lung disease.



Educational Objectives
As a result of attending this course, participants should be able to:
- Identify the main MRI techniques used to assess lung disease;
- Describe the basic pathophysiology of vaping-associated lung injury; and
- Explain the use of hyperpolarized gas MRI to assess sequela of COVID-19 pneumonia.

07:00Exposing Vaping-Associated Lung Injury
Mark Schiebler

Keywords: Contrast mechanisms: Hyperpolarized MR (Gas), Body: Lung, Cross-organ: Inflammation

Electronic Vaping Associated Lung Injury (EVALI) and Electronic Nicotine Delivery Systems (ENDS) deliver addictive biologically active particulates (one micron in size) directly into the blood stream. This is accomplished by a battery powered heated filament that vaporizes the addictive agent along with one or more carrier substances. We are at the beginning stages of understanding the biological effects of these new delivery devices and if they will decrease the incidence of lung cancer in their users compared with cigarettes. Pilot data suggests that ENDS users have a disruption in their ability to match ventilation with perfusion at the arteriolar level.
07:30 Hyperpolarized Gas MRI helps explain long-covid
Grace Parraga

Keywords: Body: Respiratory, Contrast mechanisms: Hyperpolarization, Contrast mechanisms: fMRI

We will explore new fundings using pulmonary functional MRI using inhaled 129Xe gas that help explain long-COVID in patients.
