Early identification of PCa patients at risk for biochemical recurrence (BCR) post-therapy will potentially complement definitive therapy with either neo- or adjuvant therapy to improve prognosis. BCR post definitive therapy is often associated with disease progression that might cause a bulge in the prostate gland. In this work we explored if an atlas-based comparison approach reveals shape differences in the prostate capsule as observed on pre-treatment T2-weighted MRI between prostate cancer patients who do (BCR ) and do not (BCR ) have BCR following definitive therapy.

Purpose: Transjugular intrahepatic portosystemic shunts (TIPS) were historically placed using uncovered bare-metal stents. Current practice has now shifted toward the use of polytetrafluoroethylene (PTFE)-covered stents, given the improved primary patency seen with these stents. The aim of this study was to determine whether there is any added value, such as overall survival or stent patency, when using covered stents versus uncovered stents in TIPS placement in a large cohort.

The recognition of sacral insufficiency fractures continues to be poor, and diagnosis is often delayed resulting in significant morbidity. Percutaneous sacroplasty is an image guided procedure that is safe and potentially effective for treating the pain and disability related to these fractures. Several cohort studies reviewed here report successful outcomes using this procedure, with patients experiencing nearly full pain relief immediately and longitudinally.

Purpose: To evaluate the safety and effectiveness of percutaneous acetabuloplasty in treating the pain and disability related to metastatic lesions of the acetabulum.

Materials And Methods: This institutional review board approved retrospective study examined 11 patients who underwent percutaneous acetabuloplasty in our hospital from April 2007 to June 2010. All patients gave informed consent prior to the procedure, and all records were HIPAA compliant.
