The purpose of this work was to implement a breath-hold
UTE acquisition based on an optimized 3D
stack-of-spirals acquisition, and to perform a
proof-of-concept evaluation of the method for detection
of small lung nodules in three subjects with COPD, who
had confirmed pulmonary nodules on CT. All nodules
detected with CT (ranging from approximately 3-mm to
1-cm) were apparent on MRI. Our results suggest that the
breath-hold UTE method may have potential for MR-based
detection of pulmonary nodules.
