Abstract No. 295: Pictorial assay on MR guided cryoablation

Abstract

PurposePercutaneous cryoablation under MR guidance has been shown to be an effective alternative for treatment of solid renal malignancies. This is a pictorial essay detailing challenging cases in which MR percutaneous cryoablation has been successfully performed. The aim is to aid in planning the most optimal approach and technique in difficult cases.Materials and MethodsThe pictorial essay reveals multiple solid renal tumors divided by location whether the lesion is exophytic, intraparenchymal or central as well as whether it is in the anterior or posterior portion of the kidney.ResultsMultiple approaches are detailed corresponding to the location as well as the most appropriate recommended course of action in order to minimize the chances of complications. The complicated process of MR imaging has a complicated set of artifacts that need to be understood. The essay also details how to minimize these artifactual distortions.Conclusion1) MR guided percutaneous cryoablation can be performed with a reduced rate of complication by selecting the most optimal approach depending on the location of the solid mass which is explained by this pictorial essay. 2) MR guided cryoablation is different from the other image-guided modalities because of the artifacts such as susceptibility due to the nonferromagnetic metal used in cryoablation. A planned approach as noted in this essay would help minimize such artifacts.
