Wlad T. Sobol and Joel K. Curé: Can in Vivo Assessment of Tissue Hemodynamics with Dynamic Contrast-enhanced CT Be Used in the Diagnosis of Tumors and Monitoring of Cancer Therapy Outcomes?
These results are robust enough to warrant an optimistic forecast that further refinements of this technique will produce a useful tool for improving the diagnosis of tumors and the monitoring of cancer therapy outcomes.

J. Anthony Seibert: Vertebroplasty and Kyphoplasty: Do Fluoroscopy Operators Know about Radiation Dose, and Should They Want to Know?
An increased awareness of the radiation dose and associated risks for all types of fluoroscopic procedures is certainly a good thing ... and, yes, fluoroscopy operators should want to know about radiation doses to the patient, as well as to themselves and their support staff.
