Eksperimentell: Focused Ultrasound Combined with Neoadjuvant Therapy
|
Participants will undergo six cycles of focused ultrasound-mediated targeted drug delivery combined with neoadjuvant therapy. The ultrasound parameters are set as follows: ultrasound power 9 W (acoustic pressure 3 MPa), frequency 1 MHz, pulse duration 100 μs, pulse repetition frequency 100 Hz, with 5 treatment cycles per single point. During each treatment session, 2.5 mL of SonoVue® ultrasound contrast agent microbubbles is injected via the cubital vein, followed by a 5 mL normal saline flush. Subsequently, 2.5 mL of SonoVue® microbubbles are administered every 2 minutes, with a total injection volume of 15 mL throughout the procedure. |
