ReviewIntraosseous Vascular Access in Radiology: Review of Clinical Status.
Paramedics and hospital-based providers occasionally need to place intraosseous devices to obtain vascular access in critically ill patients. Diagnostic radiologists must be prepared for the emergent administration of iodinated contrast media via the intraosseous route, and interventional radiologists should be familiar with the potential clinical uses of such access. ⋯ We present a protocol for the administration of iodinated contrast media through the intraosseous route. We also highlight the clinical and radiologic aspects of intraosseous access.

Distinguishing Untreated Osteoblastic Metastases From Enostoses Using CT Attenuation Measurements.
The purpose of this study was to determine whether CT attenuation thresholds can be used to distinguish untreated osteoblastic metastases from enostoses. ⋯ CT attenuation measurements can be used to distinguish untreated osteoblastic metastases from enostoses. A mean attenuation of 885 HU and a maximum attenuation of 1060 HU provide reliable thresholds below which a metastatic lesion is the favored diagnosis.
