Study challenges night call ban for first-year residents
February 8th 2008The decision may have been made, but the war of words surrounding the Resident Review Committee for Radiology's resolution to change call eligibility requirements from six to 12 month of residency training wages on. A study presented at the RSNA meeting finding no statistically significant difference in diagnostic accuracy between the two groups of residents is the latest salvo in the battle. The retrospective study reviewed 1464 emergency room exams by residents in the seventh and the 13th month of trai
Fusion imaging gains ground in RFA
July 6th 2005Fusion imaging is making inroads as an imaging strategy for RFA and other tumor ablation techniques. The sophisticated melding of functional and structural imaging modalities allows physicians to more accurately map out the procedure beforehand and monitor the results afterward. A few software packages allow physicians to check their real-time progress against preprocedural images, and new products and procedures to automate the process are being developed.
State of the art: Treatable tumor size increases; RFA versus cryoablation question emerges
June 7th 2005The case for radiofrequency ablation and other forms of tumor ablation has been made: Use of the technique is established for treating bone lesions and tumors of the liver, lung, kidney, and other organs. Now the focus turns to expanding the realm of treatment and pushing the limits of the technology. Two areas taking center stage are tumor size and the choice between RFA and cryoablation.
