Dual-, Multi-, and Mono-Energy CT & Iodine: Basic Concepts and Clinical Applications,graphy (DECT) implies the application of two different energies, adding to the classic single-energy multi-detector CT study, information yielded from material differentiation derived from the interaction between tissues and different energy levels. Multi-energy CT (spectral imaging) is a more speci

Renal Masses,ravenous contrast material. Pre-contrast images are used for baseline density measurements in both solid and complex cystic masses, but also provide information about morphological and structural features; post-contrast images are used to evaluate contrast-enhancement that do not necessarily indicat

Urinary Stones,erapeutic assessment of urinary tract stones. In addition to the direct visualization of a stone in the lumen of the ureter, the diagnosis of ureterolithiasis can be confirmed on the basis of several secondary signs as hydronephrosis, perinephric and periureteral stranding/edema, and unilateral rena

Adrenal Glands,amounts of intracytoplasmic lipid and are easily distinguished from non-adenomatous lesions on unenhanced multi-detector CT (MDCT). However, adenomas containing relatively small amounts of lipid account for approximately 30 % of all adenomas and cannot be distinguished from non-adenomatous lesions o

Pancreas,for patients suspected of having a pancreatic malignancy. A contrast-enhanced biphasic protocol consisting of pancreatic parenchymal and portal venous phase acquisitions is optimal for accurate detection and staging of pancreatic tumors. Spectral MDCT has the potential for improved tissue characteri
