We offer a new method for characterizing the magnitude and dynamics of the vascular
response to changes in arterial gas tensions using non-invasive blood oxygenation level …

Stroke is a syndrome characterized by a sudden neurological deficit caused by intracranial
hemorrhage or ischemia. Computed tomography (CT) maintains a primary role in the …

Hemodynamic cardiac and respiratory-cycle fluctuations are a source of unwanted non-
neuronal signal components, often called physiologic noise, in resting state (rs-) fMRI …

Bolus tracking data obtained with paramagnetic intravascular tracers are commonly
analyzed and quantified by the direct measurement of properties of the tissue concentration …

Arterial spin labeling (ASL) is an MRI perfusion imaging method from which quantitative
cerebral blood flow (CBF) can be calculated. We present a multi-TI ASL method (multi-TI …

Patients follow-up in oncology is generally performed through the acquisition of dynamic
sequences of contrast-enhanced images. Estimating parameters of appropriate models of …

Background Computed tomography (CT) perfusion has been studied as a tool to predict
delayed cerebral ischemia (DCI) and clinical outcome in spontaneous subarachnoid …

BACKGROUND AND PURPOSE: A quantitative, easily obtained measure of cerebral
hemodynamics would be valuable in planning surgical or interventional therapy for patients …

Parameter-free assessment of the time-to-peak (TTP) histogram, termed 'TTP-distribution
curve'(TDC), of dynamic susceptibility contrast-enhanced magnetic resonance imaging …

Tracer methods for studying brain function have undergone unprecedented growth and
great success over the past decade. With the advance of imaging methodologies it is now …
