Application progresses of percutaneous imaging-guided cryoablation in oncotherapy / 中国介入影像与治疗学

ABSTRACT

Percutaneous imaging-guided cryoablation (PICA) is a recently developed technique,which applies extreme hypothermia to destroy tumors guided with CT,MRI or ultrasound images.Compared with other oncologic cryoablation therapies,PICA has some advantages,such as treating under local anesthesia,superior monitoring capability on multimodal imaging,less intraoperative and postoperative pain and preservation of tissue collagenous architecture.In recent years,PICA has been used in treatment of tumors in lung,liver,kidney,breast,prostate and so on.In this article,the principle of cryoablation and the application progresses of PICA in oncotherapy were reviewed.
