Seventy-eight-year-old woman with essential tremor. (A) Intraoperative axial 2D FRFSE T2-weighted sequence acquired after the last high-energy sonication using the dedicated two-channel FUS-Head coil well demonstrates the presence of zone I (hypointense) and zone II (hyperintense) in the left nucleus ventralis intermedius. (B) Intraoperative axial 2D FRFSE T2-weighted sequence acquired using body radiofrequency coil does not visualize any lesional zones. (C) Forty-eight-hour follow-up acquired with the eight-channel phased-array head coil demonstrates enlargement of zone I and zone II and development of peripheral vasogenic edema (zone III). Both readers agreed on the presence of these imaging findings.
