Dynamic Contrast-Enhanced MR Imaging in Head and Neck Cancer.

Dynamic contrast-enhanced (DCE) MR imaging uses rapid sequential MR image acquisition before, during, and after intravenous contrast administration to elucidate information on the microvascular biologic function of tissues. The derived pharmacokinetic parameters provide useful information on tissue perfusion and permeability that may help to evaluate entities that otherwise appear similar by conventional imaging. When specifically applied to the evaluation of head and neck cancer, DCE-MR imaging may provide valuable information to help predict treatment response, discriminate between posttreatment changes and residual tumor, and discriminate between various head and neck neoplasms.

Strategies for Improving the Value of the Radiology Report: A Retrospective Analysis of Errors in Formally Over-read Studies.

Purpose: The radiology report is a critical component of the Imaging Value Chain. Unfortunately, the quality of this aspect of a radiologist's work is often heterogeneous and fails to add significant value to the referring provider and, ultimately, the patient. Gauging what defines quality can be elusive; however, we elucidate techniques that can be employed to ensure that reports are more comprehensible, actionable, and useful to our customers.
