Studie av hjärtats väggrörlighet och perfusion Application

The most commonly calculated parameter is k-trans . Arterial spin labeling (ASL) MR perfusion is an MR perfusion technique which does not require intravenous administration of contrast (unlike DSC perfusion and DCE perfusion ). Instead it exploits the ability of MRI to magnetically label arterial blood below the imaging slab. The parameter most commonly derived is cerebral blood flow (CBF) . MR perfusion imaging refers to several recently developed techniques used to non-invasively measure cerebral perfusion via assessment of various hemodynamic measurements such as cerebral blood volume, cerebral blood flow, and mean transit time.

MR-perfusion vid lungembolism Två huvudsakliga tekniker har använts för MR-perfusion av lungorna vid lungembolism. Bäst studerad är perfusion efter en intravenös bolusinjektion av Gd-KM [9]. Även tekniker där man kombinerar MR-angiografi med MR-perfusion vid ett undersökningstillfälle har beskrivits [8].

In most adult practices, an alternative technique is used called CT perfusion. MR perfusion and diffusion in acute ischemic stroke: human gray and white matter have different thresholds for infarction.

Contrast material-enhanced myocardial perfusion imaging by using cardiac magnetic resonance (MR) imaging has, during the past decade, evolved into an accurate technique for diagnosing coronary artery disease, with excellent prognostic value. Perfusion MR Imaging. Perfusion is a biological function that refers to the delivery of oxygen and nutrients to tissue by means of blood flow.

It also gives information about cerebral blood flow (CBF), relative cerebral blood volume (rCBV) etc. In most adult practices, an alternative technique is used called CT perfusion.

Crossref Medline Google Scholar; 19 Rose SE, Janke AL, Griffin M, Finnigan S, Chalk JB. 2021-04-08 · Arterial spin labelling (ASL) is a contrast-free MR perfusion technique that uses magnetically labelled water as a freely diffusible tracer to measure cerebral blood flow (CBF).7–9 Twenty-five years after its introduction and with significant advances in sequence design, hardware technology and postprocessing techniques, ASL has become readily available for routine clinical practice in MR Physics Group Our research group, situated in the expanding Öresund region in southern Sweden, is active in the field of medical magnetic resonance, and has its primary focus on development of new techniques for assessment of functional information related to perfusion, diffusion, cortical activation/fMRI and flow.

Perfusion analysis was performed with the Philips Neuro Perfusion package (Philips Extended MR Workspace R2.6.3.3). Based on DSA data, regions-of-interest (ROIs) were uniformly drawn on pre-operative CCA perfusion images representing ECA dural, ICA dural, and pial supplies.
