Synopsis

Shorter examination time might miss the appropriate timing for depicting the “delayed-enhanced” lesions, such as brain metastasis and multiple sclerosis plaques. We focused on the CENTRA-PLUS view-ordering framework and tried to modify the k-space profile ordering to enable completely timing-reversed (SLUP-ARTNEC). The purpose of this study is to demonstrate the feasibility of SULP-ARTNEC in the patients with brain metastasis. SLUP-ARTNEC is the unique approach in the post compressed sensing era that can improve the image contrast between delayed-enhanced brain metastasis lesions and background tissues in the contrast-enhanced studies without having the extra-waiting time, resulting in maintain the shorter examination time.
