Renal cell carcinoma is a relatively common tumor, with an estimated 63,000 new cases being diagnosed in the United States in 2016. Surgery, be it with partial or total nephrectomy, is considered the mainstay of treatment for many patients. However, those patients with small renal masses, typically less than 3 to 4 cm in size who are deemed unsuitable for surgery, may be suitable for percutaneous thermal ablation. We review the various treatment modalities, including radiofrequency ablation, microwave ablation, and cryoablation; discuss the advantages and disadvantages of each method; and review the latest data concerning the performance of the various ablative modalities compared with each other, and compared with surgery.

Purpose: To develop and evaluate a volumetric proton resonance frequency shift (PRF)-based thermometry method for monitoring thermal ablation in moving tissues.
Methods: A golden-angle-ordered 3D stack-of-radial MRI sequence was combined with an image-navigated multi-baseline (iNAV-MB) PRF method to reconstruct motion-compensated 3D temperature maps with high spatiotemporal resolution and volumetric coverage. Two radial MRI reconstruction techniques, k-space weighted image contrast filter (KWIC) and golden-angle radial sparse parallel (GRASP) MRI, were implemented and compared within a sliding window reconstruction framework.

ObjectiveRecurrent varicose veins (RVVs) following open surgical procedures are common and present significant treatment challenges. Redo open surgery (rOS) presents risks leading to a need for alternative treatment options. This study compares the safety and efficacy of ultrasound-guided foam sclerotherapy (UGFS), used to treat recurrent reflux and remove neovascular and tributary venous networks in the thigh, to redo open surgery (rOS) for the treatment of C2r.

Background: In catheter-based radiofrequency ablation (RFA), energy is delivered to heterogeneous thin-walled tissues to induce therapeutic heating. Variations in electrical and mechanical properties of tissue contents have a great effect on outcomes.
Purpose: The objective of this study is to develop models that replicate tissue heterogeneity and visualize ablation zones for effective evaluation and optimization.

ObjectiveLower extremity varicose veins are a common chronic venous disorder, affecting approximately 23% of adults globally. Although endovenous thermal ablation, particularly radiofrequency ablation (RFA), has become the preferred treatment, post-procedural deep vein thrombosis (DVT) remains a concern. The necessity of pharmacologic prophylaxis following RFA remains controversial.
