For the most part, a system of component coding is used in these cases, in order to accurately describe the separately identifiable surgical and imaging services performed by the radiologist. In this way, the Current Procedural Terminology (CPT) code structure recognizes that there can be variations in the services performed during diagnostic angiography and vascular transcatheter therapies, wh...

Energy imparted is a measure of the total ionizing energy deposited in the patient during a radiologic examination and may be used to quantify the patient dose in diagnostic radiology. Values of the energy imparted per unit exposure-area product, omega (z), absorbed by a semi-infinite water phantom with a thickness z, were computed for x-ray spectra with peak x-ray tube voltages ranging from 50...

A new edition of the international standard IEC 60627 of anti-scatter grids will be published within some months. The presentation deals with the most important characteristics of anti-scatter grids according to the standard. Introduction During imaging in diagnostic radiology, X-ray beam is scattered on all media between X-ray source and X-ray image receptor. The most important one from these ...

Diagnostic and interventional radiology play major roles in the evaluation and management of liver transplant patients. This article begins with a discussion of imaging techniques used in the preoperative evaluation of transplant candidates. Surgical approaches and normal posttransplant anatomy are presented. An in-depth discussion of the radiologic evaluation of posttransplantation complicatio...
