查询词典 echo-location

Some of them with visual loss, optic papilledema and orbital mass. B-scan ultrasonography revealed a cyctic tumor and a strong echo spot with spontaneous movement. On CT scanning, found was a well-defined hyperdensity mass in which there was a low density area. On MRI, the signal intensity of T1WI of cystic fluid was low or moderate and of T2WI was high, while the signal intensity of T1WI and T2WI of surounding scar tissue was still low.
