Contrast-enhanced MRI versus myelography and contrast-enhanced CT in postdiskectomy problems
European Spine Journal, 1992The differentiation between scar tissue and disk herniation is essential in postdiskectomy problems of the lumbar spine, since reoperation on scar tissue alone is often unfavourable. Epidural scar is a vascularized tissue, and enhancement can be seen after intravenous contrast injection, allowing differentiation from avascular disk material.

Multiphase contrast-enhanced CT of the liver with a multislice CT scanner
European Radiology, 2003Our objective was to assess the effects of the injection rate of contrast material and of a 5% dextrose flush on enhancement in multiphase hepatic CT using a multislice CT scanner. Most patients had chronic hepatitis and/or liver cirrhosis. One hundred eighty examinations, in which two sequential acquisitions were performed during a single breath-hold ...

Efficacy of Contrast-Enhanced CT in Assessing the Endometrium
American Journal of Roentgenology, 2008The purpose of our study was to determine the efficacy of contrast-enhanced CT in detecting a thickened endometrium. We used transvaginal sonography as the reference standard.Between March 2005 and January 2007, data from 259 patients (mean age, 47 years; age range, 18-90 years) who underwent transvaginal sonography and contrast-enhanced CT of the ...

Preparative Fasting for Contrast-enhanced CT: Reconsideration
Radiology, 2012To evaluate the evidence on the value of preparative fluid fasting for patients undergoing elective computed tomography (CT) with intravenous administration of contrast material and to survey leading institutions in a number of countries on their current policies in this regard.This study qualified for exempt status by the institutional review board ...

Calcium Scoring and Contrast-Enhanced CT Angiography
Current Molecular Medicine, 2006Computed tomography (CT) technology has emerged as the most promising imaging modality for the noninvasive evaluation of the coronary circulation. Of the CT-based approaches, multidetector-row computed tomography (MDCT) and to a lesser extent electron beam computed tomography offer the potential of providing not only data on the spatial extent and ...

Contrast-enhanced CT findings of intravenous leiomyomatosis
Clinical Radiology, 2018To characterise the contrast-enhanced computed tomography (CT) imaging findings of nine patients with intravenous leiomyomatosis (IVL).The contrast-enhanced CT imaging findings of nine patients with histopathologically proven IVL were examined. The location, morphology, extension pathway, adhesion, and degree and pattern of enhancement of the tumour ...

Nihon rinsho. Japanese journal of clinical medicine, 1996
Although CT is one of major diagnostic imaging methods, the role of CT in the detection and diagnosis of early carcinomas depends on the organ and character of the tumors. Because difference in attenuation between lung parenchyma and carcinomas is large, contrast enhanced CT is not effective to diagnose early lung carcinoma.

Investigative Radiology, 1983
The commonly used contrast medium metrizoate (Isopaque Cerebral) or the new nonionic iohexol were injected intravenously for enhancement of cranial CT in a randomized double blind study. Each group consisted of 105 patients. No serious reactions occurred.

The British Journal of Radiology, 2008
The aim of this study was to compare the enhancement pattern of intrahepatic cholangiocarcinoma (ICC) on contrast-enhanced ultrasound (CEUS) with that on contrast-enhanced computed tomography (CECT). 40 pathologically proven ICC lesions in 40 patients were evaluated retrospectively with both CEUS and CECT.

Multi-slice CT contrast enhancement regimens
Clinical Radiology, 2004Historically, the development of progressively faster Computed Tomography (CT) technology has dictated a recurrent need to re-examine intravenous contrast agent enhancement regimens. The most recently introduced development, the very fast, multi-slice helical/spiral systems, have raised the same issue yet again.
