Determinants of image quality in respiratory triggered free breathing lung MRI at 0.55 T in adults.

ABSTRACT:

Background

Mid-field MRI scans (0.55 T) have gained attention for pulmonary imaging because of reduced susceptibility artifact, but image quality remains variable across patient populations, limiting its clinical adoption.

Purpose

To identify technical and clinical factors associated with poor image quality in 0.55 T lung MRI in adults with various pulmonary diseases.

Materials and methods

Adults with major pulmonary disease (eg, infection, pulmonary fibrosis, cancer) who were scheduled for chest CT or PET/CT at a single health care site were prospectively recruited from January to August 2023 to undergo same-day 0.55 T MRI scans. Exclusion criteria included inability to communicate in English, overlapping pulmonary diagnoses already represented, or declining consent.
