Eighteen cases with bladder tumors were examined by means of superconducting MRI. Sequences used were spin echo (TR/TE (msec) = 500/20 as T1WI (weighted image) and 1500/80 as T2WI) and serial "fast spin echo (fast SE)" pre/post Gd-DTPA administration. "Fast SE" was a new technique offering a distinct T1WI (TR/TE = 100/14, utilizing a 14 second breath hold).(More)
CT-perfusion (CTP) examination was performed in 30 cases of acute cerebral infarction (ACI) caused by middle cerebral artery (MCA) occlusion. Data were analyzed using cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT). The results of the affected side were compared with those of the other side in terms of relative value and(More)
Current magnetic resonance imaging techniques demonstrated MR findings of Dyke-Davidoff-Masson syndrome in a 44-year-old man. Statistical parametric mapping analysis of the T1-weighted images showed focal atrophy in the basal ganglia. Three-dimensional white matter fibers of corticospinal tracts, corpus callosum and cingulate bundle were demonstrated using(More)
