Overview

Preliminary study demonstrates dynamic imaging of histotripsy lesions in agar phantom, suggesting MRI can enhance monitoring during procedures.

Key Points

  • Dynamic imaging captured the progress of histotripsy lesions in an agar phantom, revealing distinct characteristics.
  • Intra-procedural monitoring used T2-weighted turbo spin echo imaging with 10-second updates for rapid assessments.
  • Pulsed focused ultrasound applied with a 2% duty factor delivered up to 2000 pulses in a 3T MRI scanner.
  • Mild thermal effects were observed, indicating phantom response while temperatures remained below hyperthermia levels.
