Repeatability of Cerebral Perfusion Using Dynamic Susceptibility Contrast MRI in Glioblastoma Patients.
OBJECTIVES This study evaluates the repeatability of brain perfusion using dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) with a variety of post-processing methods. METHODS Thirty-two patients with newly diagnosed glioblastoma were recruited. On a 3-T MRI using a dual-echo, gradient-echo spin-echo DSC-MRI protocol, the patients were scanned twice 1 to 5 days apart. Perfu...

متن کاملDynamic susceptibility contrast perfusion MRI (with pitfalls)
Since the first studies in the late 1980s and early 1990s, dynamic susceptibility contrast MRI (DSC-MRI, also known as ‘bolus tracking’) has become a very powerful technique for the assessment of perfusion, and perfusion-related parameters (see (1,2) for recent reviews). Despite the need of an exogenous MR agent (cf. arterial spin labeling techniques), DSC-MRI is currently the most common MR pe...
متن کاملBayesian estimation of cerebral perfusion using reduced-contrast-dose dynamic susceptibility contrast perfusion at 3T.
BACKGROUND AND PURPOSE DSC perfusion has been increasingly used in conjunction with other contrast-enhanced MR applications and therefore there is need for contrast-dose reduction when feasible. The purpose of this study was to establish the feasibility of reduced-contrast-dose brain DSC perfusion by using a probabilistic Bayesian method and to compare the results with the commonly used singula...
متن کاملA Study of APOE and Cerebral Perfusion in Adult Offspring of Patients with Alzheimer's Dementia using Dynamic Susceptibility Contrast MRI
Blood flow is a candidate marker for detecting early stages of AD because a decrease in cerebral perfusion has already been observed with perfusion MRI in AD using Arterial Spin labeling (ASL) techniques. However, the ASL perfusion method does not provide complementary information on blood volume and transit time that can help distinguish reduced perfusion due to brain atrophy from vasoregulato...
