Perfusion is a fundamental biological function that refers to the delivery of oxygen and
nutrients to tissue by means of blood flow. Perfusion MRI is sensitive to microvasculature …

Cerebral perfusion, also referred to as cerebral blood flow (CBF), is one of the most
important parameters related to brain physiology and function. The technique of dynamic …

BACKGROUND AND PURPOSE: Relative cerebral blood volume (rCBV) estimates for high-
grade gliomas computed with dynamic susceptibility contrast MR imaging are artificially …

MR perfusion imaging is becoming an increasingly common means of evaluating a variety of
cerebral pathologies, including tumors and ischemia. In particular, there has been great …

The principles of cerebral perfusion imaging by the method of dynamic susceptibility contrast
magnetic resonance imaging (DSC‐MRI)(bolus tracking) are described. The MRI signals …

Background—MR techniques have been very powerful in providing indicators of tissue
perfusion, particularly in studies of cerebral ischemia. There is considerable interest in …

The acetazolamide (ACZ) challenge test is a useful clinical tool and a reliable predictor of
critically reduced perfusion. In patients with chronic steno-occlusive disease, the ability to …

Gradient‐echo sequences are widely used in magnetic resonance imaging (MRI) for
numerous applications ranging from angiography to perfusion to functional MRI. Compared …

Since the invention of arterial spin labeling (ASL) it has been acknowledged that ASL does
not allow reliable detection of a white matter (WM) perfusion signal. However, recent …

BACKGROUND AND PURPOSE: Blood vessels are usually conspicuous on dynamic CT
perfusion images. The presence of large vessels may lead to overestimation of the …
