Percutaneous CT-Guided Cryoablation of the Salivary Glands in a Porcine Model.

Purpose: To evaluate the imaging, histologic changes and safety of computed tomography (CT)-guided cryoablation of the parotid glands in a porcine model.

Materials And Methods: Unilateral CT-guided parotid gland cryoablation was performed in 5 juvenile miniature pigs. The ablated parotid glands underwent 2 cycles of 10-minute freeze and 5-minute thaw using three 17-g cryoprobes.
