Contrast-enhanced MR angiography

Der Radiologe, 1996
Despite many optimizations, the current limitations of plain MR angiography include: saturation that impairs the visualization of veins and arteries with slow flow and spin-dephasing signal voids in locations with turbulent flow. Recently, the use of contrast agents has been proposed to cope with these remaining problems.

Contrast-enhanced ultrasound fundamentals: the pharmacodynamics and pharmacokinetics of contrast. Basics of contrast-enhanced ultrasound imaging

Radiología (English Edition)
Contrast-enhanced ultrasound (CEUS) is a medical imaging technique that offers multiple advantages over other modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). These advantages include portability, no ionising radiation and no renal toxicity, with the great advantage of real-time imaging.

Contrast-Enhanced Ultrasound Ventriculography

Operative Neurosurgery, 2012
During external ventricular drainage (EVD) weaning, cranial computed tomography (cCT) is necessary to evaluate ventricle width. Because intrahospital transfer of critically ill patients is associated with higher mortality, bedside techniques are necessary to evaluate ventricle width.

Comparison of Contrast-Enhanced Mammography and Contrast-Enhanced Breast MR Imaging

Magnetic Resonance Imaging Clinics of North America, 2018
Contrast-enhanced mammography (CEM) is a contrast-enhanced modality for breast cancer detection that utilizes iodinated contrast and dual-energy imaging performed on a digital mammography unit with only slight modifications. It is approved by the US Food and Drug Administration, commercially available, and in routine clinical use at centers around the ...

A Histogram Adaptation for Contrast Enhancement

2011
Histogram equalization is the common methods used for improving contrast in image processing application. But this technique is not well suited for implementation in consumer electronics such as television as it introduces unnecessary visual deterioration such as the saturation effect. It causes changes in the brightness of the input image.

Contrast-Enhanced Ultrasound for the Prostate

2009
Imaging of the prostate can be performed using different imaging techniques and has several applications in the evaluation of benign and malignant prostate diseases. Many imaging techniques are used to detect and follow up abnormalities of the prostate such as prostatitis, abscesses, benign prostate hyperplasia, and prostate cancer, or to investigate ...

Contrast-Enhanced Computerized Tomography

Archives of Internal Medicine, 1978
In this issue of theArchives(p 628) Heath et al describe a patient in whom cerebral abscesses were eventually documented by computerized tomography (CT). Using this technique, which has been thoroughly described in the literature, they at first did not diagnose the lesion, then later they did identify at least one abscess after the patient had been ...
