Administration and dosage of iohexol, a nonionic contrast medium, for dynamic renal computed tomography.
We investigated the optimal method of administering iohexol, which contains 300 mg iodine/ml (Omnipaque 300), a nonionic contrast medium, to maintain adequate renal contrast while reducing artifacts during dynamic CT scanning. In this study, 76 patients with renal disease received 10-50 ml of iohexol as follows: group I (14 patients), 20 ml injected as an intravenous bolus for 5 sec, followed b...
متن کاملStatistical iterative reconstruction algorithm for X-ray phase-contrast CT
Grating-based phase-contrast computed tomography (PCCT) is a promising imaging tool on the horizon for pre-clinical and clinical applications. Until now PCCT has been plagued by strong artifacts when dense materials like bones are present. In this paper, we present a new statistical iterative reconstruction algorithm which overcomes this limitation. It makes use of the fact that an X-ray interf...

متن کاملPhase contrast in laboratory-based X-ray CT
When scanning weakly attenuating samples using an X-ray tube with a very small focal spot size, the acquired projections not only contain absorption contrast, but also phase contrast due to refraction of the X-rays. Although the resulting edge enhancement can be beneficial in radiography, the tomographic reconstruction of such mixed projections using a conventional algorithm yields cross-sectio...
متن کاملBiotransformation of nonionic X-Ray contrast agents In vivo and In vitro.
Liposomes loaded with the nonionic iodinated contrast agent iodixanol were injected i.v. into monkeys, rats, and dogs, and liver samples were analyzed by HPLC and mass spectrometry. Two metabolites (M1 and M2), with UV spectra identical to those of the iodixanol isomers (exo and endo) and with a mass increase of 162 compared with iodixanol, were detected. Incubations of iodixanol-liposomes or i...
