Synopsis

Keywords: Lung, Lung, Zero Echo Time

Motivation: MRI can detect pulmonary lesions, but its efficacy and the optimal method need further confirmation.

Goal(s): To evaluate the feasibility of MRI for different types of pulmonary lesions and optimize protocol selection.

Approach: Assess the diagnostic performance of various MRI protocols in detecting pulmonary lesions.

Results: Standard body MRI protocols are effective in detecting pulmonary lesions, with the respiratory-triggered 3D Zero Echo Time (Rtr 3D ZTE) sequence providing imaging most comparable to CT.

Impact: This study provides guidance on MRI scanning strategies for pulmonary lesions, recommending the respiratory-gated 3D ZTE sequence as the primary choice for subsolid lesions.
