K-edge ratio method for identification of multiple nanoparticulate contrast agents by spectral CT imaging.
OBJECTIVE Recently introduced energy-sensitive X-ray CT makes it feasible to discriminate different nanoparticulate contrast materials. The purpose of this work is to present a K-edge ratio method for differentiating multiple simultaneous contrast agents using spectral CT. METHODS The ratio of two images relevant to energy bins straddling the K-edge of the materials is calculated using an ana...
متن کاملmagnetic resonance imaging contrast agents: a review of literature
magnetic resonance imaging (mri) contrast agents most commonly agents used in diagnosing different diseases. several agents have been ever introduced with different peculiar characteristics. they vary in potency, adverse reaction and other specification, so it is important to select the proper agent in different situations. we conducted a systematic literature search in medline/pubmed, web of s...
متن کاملLiver-specific contrast agents
In the patient with cancer, magnetic resonance imaging is increasingly used as a diagnostic tool for disease detection, lesion characterization, as well as the assessment of treatment response. Although non-contrast T1-weighted and T2-weighted imaging, together with low molecular weight extracellular gadolinium contrast-enhanced T1-weighted magnetic resonance imaging remain the cornerstone for ...
متن کاملStrategies for Target-Specific Contrast Agents for Magnetic Resonance Imaging.
This review describes recent research efforts focused on increasing the specificity of contrast agents for proton magnetic resonance imaging (MRI). Contrast agents play an indispensable role in MRI by enhancing the inherent contrast of images; however, the non-specific nature of current clinical contrast agents limits their usefulness. This limitation can be addressed by conjugating contrast ag...
متن کاملNo Association between Gadolinium-Based Contrast Agents and Development of Nephrogenic Systemic Fibrosis: a Case Study
Nephrogenic systemic fibrosis (NSF), previously known as nephrogenic fibrosing dermopathy, is an emerging systemic fibrosing disorder that develops in the setting of renal insufficiency. Nephrogenic fibrosing dermopathy (NFD) is a fibrosing condition of the skin which shows an increased number of dendritic cells, fibroblasts and thickened collagen fibers resembling scleromyxedema. It is charact...
