Fig. 3From: Sononeoperfusion: a new therapeutic effect to enhance tumour blood perfusion using diagnostic ultrasound and microbubblesA: The percentage of tumour perfusion increased 4 hours after treatment compared with pre-treatment. In Group B, the incremental perfusion area was 21.42%. **P < 0.01.
