Clinical TrialPrognostic value of 18f-fluorodeoxyglucose positron emission tomography-computed tomography in predicting survival in patients with unresectable metastatic melanoma to the liver undergoing yttrium-90 radioembolization.
To investigate the prognostic value of (18)F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) in predicting survival in patients with unresectable metastatic melanoma to the liver undergoing yttrium-90 ((90)Y) radioembolization. ⋯ MTB based on (18)F-FDG PET-CT performed before treatment was found to be a negative prognostic factor for patient survival after (90)Y radioembolization for unresectable metastatic melanoma to liver.

Indirect computed tomography venography of the lower extremities using single-source dual-energy computed tomography: advantage of low-kiloelectron volt monochromatic images.
To study the performance of dual-energy indirect computed tomography (CT) venography from single-source dual-energy CT in the assessment of lower extremity deep venous thrombosis (DVT). ⋯ Optimal image quality with substantially higher venous attenuation is provided by 50-keV monochromatic images from dual-energy CT venography acquisition compared with 70-keV images. The 50-keV monochromatic images increase the confidence in the image interpretation of DVT and decrease the number of indeterminate studies.

Clinical TrialAMPLATZER Vascular Plug 4 for proximal splenic artery embolization in blunt trauma.
A consecutive case series was conducted evaluating proximal splenic artery embolization (SAE) with the AMPLATZER Vascular Plug 4 (AVP4) (St. Jude Medical, Inc, St. Paul, Minnesota) in eight patients with high-grade splenic trauma. ⋯ There were no immediate complications. One patient developed a perisplenic abscess requiring percutaneous drainage and antibiotics. Results of this initial study show the suitability of the AVP4, with its ease of deployment without a guiding sheath and accurate placement, as a viable adjunct to nonoperative management of blunt splenic injury.

Interventional radiologists' involvement in evaluation and management services and association with practice characteristics.
To characterize the current state and level of interventional radiology evaluation and management (E&M) services provided to the Medicare population and to investigate the relationship between the level of E&M services provided by an individual provider and volumes, charges, and types of procedures performed. ⋯ This study found significant differences between practice characteristics of IRs providing high and low levels of E&M services. The results suggest that greater involvement in E&M is associated with higher-reimbursement procedural work.
