Dynamic Contrast Enhanced Imaging After Canine Prostate Cryoablation
Liu E, Butts Pauly K, Bouley D, Daniel B
MR-guided cryoablation is a promising minimally invasive therapy for prostate tumors that are solitary and unilateral. The roles of imaging are targetting, monitoring, and post-therapy evaluation. The purpose of this work was to evaluate previously frozen prostate tissue with dynamic and 3D contrast enhanced imaging. Three canine prostates were frozen under MRI guidance. After complete thaw to normal body temperature, dynamic CE and 3D CE images were acquired. The enhancement patterns and timecourses are evaluated and compared to TTC stained sections.
