Examples of improved lesion detection of echo 2. A, A 56-year-old man status post posterior fossa tumor resection. Right cerebellar injury is more conspicuous on echo 2 and was confirmed to have reduced diffusion based on ADC. B, A 39-year-old man with known Moyamoya disease status post right superficial temporal artery to middle cerebral artery anastomosis presented with acute strokelike symptoms. Superficial temporal cortical lesion (closed arrow) and a punctate putaminal lesion (arrowhead) are confirmed with reduced diffusivity based on the ADC map. Also note improved delineation of a small subdural hematoma on echo 2 (open arrow).
