Outline of Final Research Achievements

Black-blood imaging is widely used in magnetic resonance imaging to suppress signals arising from blood flow. It could contribute to improving the conspicuity of lesions within the areas adjacent to blood vessels. The results of our volunteer study suggested that peripheral pulse gating is a feasible method for black-blood lung MR imaging. Systolic phase should be selected to obtain a strong and uniform black-blood effect.
In the clinical study, black-blood lung MR imaging provided an acceptable detection rate for nodular lung lesions compared with CT examination. MR could be a feasible and promising imaging modality in detecting lung nodules.
