Background: The human body contains of different tissues and cavities with different physical and radiological properties. Most important among these are tissues and cavities that are radiologically different from water, including lungs, sinuses and bones. Gel dosimetry provides a unique feature to display dose distributions occurring in clinical radiation therapy in three dimensions. Materials...

OBJECTIVES The purpose of this study was to evaluate the image quality and diagnostic accuracy of very low-dose, dual-source computed tomography (DSCT) angiography for the evaluation of coronary stents. BACKGROUND Iterative reconstruction (IR) leads to substantial reduction of image noise and hence permits the use of very low-dose data acquisition protocols in coronary computed tomography ang...
Adrenal masses that are found incidentally should be evaluated with both imaging and hormonal studies. The attenuation coefficient on noncontrast computed tomography (CT), expressed in Hounsfield units (HU), is better than tumor size in differentiating adrenal adenomas and hyperplastic lesions from nonadenomas. All patients should undergo hormonal evaluation for Cushing syndrome and pheochromoc...
