Early detection with MRI of incomplete treatment of spine metastases after percutaneous cryoablation

To evaluate post-ablation MRI for the detection of incompletely treated spinal osseous metastases (SOM) after cryoablation and to propose a post-ablation imaging classification. After IRB consent, all patients treated with cryoablation of SOM between 2011 and 2017 having at least 1-year minimum follow-up and a spine MRI within 4 months after cryoablation were retrospectively included. A classification of MRI images into four types was set up....
