Preoperative prognostic value of dynamic contrast-enhanced MRI-derived contrast transfer coefficient and plasma volume in patients with cerebral gliomas.
BACKGROUND AND PURPOSE The prognostic value of dynamic contrast-enhanced MR imaging-derived plasma volume obtained in tumor and the contrast transfer coefficient has not been well-established in patients with gliomas. We determined whether plasma volume and contrast transfer coefficient in tumor correlated with survival in patients with gliomas in addition to other factors such as age, type of ...
متن کاملAutomatic Prostate Cancer Segmentation Using Kinetic Analysis in Dynamic Contrast-Enhanced MRI
Background: Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) provides functional information on the microcirculation in tissues by analyzing the enhancement kinetics which can be used as biomarkers for prostate lesions detection and characterization.Objective: The purpose of this study is to investigate spatiotemporal patterns of tumors by extracting semi-quantitative as well as w...
متن کاملDynamic contrast - enhanced MRI in cancer REVIEW
Dynamic contrast-enhanced MRI has been proven to be a valuable technique in cancer imaging. The poorly formed and leaky vessels formed during angiogenesis to supply tumors facilitate an increased uptake of intravenously administered contrast agents in comparison to normal vasculature. The use of mathematical modeling techniques on the change in tumor signal intensity as a function of time provi...
متن کاملA novel MRI contrast agent synthesized by ion exchange method
Objective: In this study, the zeolite-coated iron oxide nanoparticles were evaluated as MRI contrast agent and effect of the nanocomposite synthesis method on MRI contrast was tested. Materials and Methods: Ion exchange method was used for synthesis of iron oxide-zeolite and the as prepared nanocomposite was characterized by XRD, FESEM and TEM. The nanocomposite toxicity in the cell culture, a...
متن کاملQuantification of blood-brain-barrier permeability dysregulation and inflammatory activity in MS lesions by dynamic-contrast enhanced MR imaging
Objective: Measurement of blood-brain permeability dysfunction in active and chronic MS lesions with T1-weighted dynamic contrast-enhanced MRI to show variation in inflammatory activity Background: blood-brain-barrier perfusion characterization impaired in MS as some studies have shown recently buta comparison between perfusion parameters in contrast-enhanced and non-enhanced lesions not have ...
