Oh J, et al. - This study was undertaken to determine if black-blood imaging improves the diagnostic accuracy for leptomeningeal carcinomatosis vs contrast-enhanced gradient recalled-echo and contrast-enhanced spin-echo and if the grade of leptomeningeal carcinomatosis assessed on black-blood imaging significantly predicts progression-free survival. No significant differences were found among contrast-enhanced gradient recalled-echo, contrast-enhanced spin-echo, and black-blood imaging in terms of specificities. In patients with leptomeningeal carcinomatosis, black-blood imaging could improve diagnostic accuracy and predict progression-free survival.
