Endocare cryoablation can be guided by ultrasound (US), CT, X-ray, DSA, simulator, etc. Good intraoperative imaging monitoring ensures accurate control of ablation zones.
CT Guidance In CT imaging, ice ball produces a 40 Hounsfield unit drop in attenuation8 which is shown as low-density shadow. CT allows for complete visual monitoring and verification of the ice ablation zone.
Ultrasound Guidance In US imaging, ice ball is clearly visible. The ice is in low echo field (dark) while its periphery is a strong echo field (bright). |
