Dynamic 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 کاملReproducibility of Dynamic Contrast-Enhanced MRI in Renal Cell Carcinoma
The objective of this study was to investigate the intra- and interobserver as well as scan-rescan reproducibility of quantitative parameters of renal cell carcinomas (RCCs) with dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). A total of 21 patients with clear cell RCCs (17 men, 4 woman; age 37-69 years, mean age 54.6 years, mean size, 5.0 ± 2.2 cm) were prospectively recruited ...
متن کاملFDG-avid portal vein tumor thrombosis from hepatocellular carcinoma in contrast-enhanced FDG PET/CT
Objective(s): In this study, we aimed to describe the characteristics of portal vein tumor thrombosis (PVTT), complicating hepatocellular carcinoma (HCC) in contrast-enhanced FDG PET/CT scan. Methods: In this retrospective study, 9 HCC patients with FDG-avid PVTT were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), which is a comb...
متن کاملQuantification of cerebral perfusion with "Real-Time" contrast-enhanced ultrasound.
BACKGROUND No noninvasive technique is currently capable of "real-time" assessment and monitoring of cerebral blood flow (CBF). We hypothesized that cerebral perfusion could be accurately measured and monitored in "real time" with contrast-enhanced ultrasound (CEU). METHODS AND RESULTS Cerebral perfusion was assessed in 9 dogs through a craniotomy with CEU at baseline and during hypercapnia a...
متن کاملDynamic Contrast Enhanced T1-weighted Perfusion MRI for Measuring Cerebral Perfusion Increase after Visual Stimulation
Introduction: Being able to measure cerebral perfusion and cerebral blood volume quantitatively is of great importance when it comes to diagnosing and treating various cerebrovascular diseases and other brain disorders. In a clinical setting, MR perfusion imaging is normally performed using dynamic susceptibility contrast imaging. When it comes to absolute quantification, this method has severa...
