Purpose: We surveyed ordering physician attitudes, knowledge, and behavior with regard to computed tomography (CT)-related radiation exposure at a large medical center.
Methods: Sixteen questions were sent via electronic survey to 350 physicians.
Results And Conclusion: The ability to quickly rule in or rule out conditions effectively strongly influenced the decision to order CT (85%-99%).
Purpose: To evaluate the safety and efficacy of percutaneous ablation methods for the treatment of metastatic pheochromocytomas (PCCs) and paragangliomas (PGLs).
Materials And Methods: From May 2001 to November 2009, 10 patients (mean age 45 years) with metastatic PCCs and PGLs were identified and treated with percutaneous ablation. All patients were given appropriate medication before the ablation procedure.
Purpose: To compare transarterial chemoembolization (CE) versus yttrium-90 ((90)Y) radioembolization (RE) for liver-dominant metastatic colorectal adenocarcinoma as salvage therapy.
Materials And Methods: Of 36 patients, 21 underwent CE (37 procedures; 11 men; mean age, 67 years; 16 with Child-Pugh class A disease) and 15 underwent (90)Y RE (19 procedures; 11 men; mean age, 64 years; 13 with Child-Pugh class A disease) for liver-dominant colorectal adenocarcinoma. Mean index dominant lesion sizes were 9.
The Comet assay (single cell gel electrophoresis assay) measures DNA strand breaks in individual cells. In the assay cells are embedded in agarose, lysed, and electrophoresed under low voltage, allowing migration of damaged DNA. The DNA is stained and subsequently viewed with an epifluorescent microscope.
