Percutaneous ablation of malignant and locally aggressive solid tumors in pediatric patients.

Image-guided percutaneous ablation is an accepted treatment modality for common adult cancers. Unfortunately, its use in patients younger than 18 years is rare. This retrospective review presents our series of pediatric patients treated with ablation at our institution.

Impact of Magnetic Resonance Imaging (MRI) Findings on Management of Symptomatic Patients Following Radiofrequency Ablation (RFA) of Osteoid Osteoma (OO).

Object: To assess the impact of MRI findings on management of symptomatic patients following RFA of OO.

Materials & Methods: Retrospective review of 43 patients with RFA for OO between June 2010 and June 2017 was performed. Patient, nidus and ablation data were reviewed.

Pathophysiology of right ventricular failure in acute pulmonary embolism and chronic thromboembolic pulmonary hypertension: a pictorial essay for the interventional radiologist.

Pulmonary embolus (PE) is the third most common cause of cardiovascular death with more than 600,000 cases occurring in the USA per year. About 45% of patients with acute PE will have acute right ventricular failure, and up to 3.8% of patients will develop chronic thromboembolic pulmonary hypertension (CTEPH) with progressive, severe, chronic heart failure.
