  • organ
  • Retrograde perfusion (retroperfusion) is an artificial method of providing blood supply to an organ by delivering oxygenated blood through the veins. (wikipedia.org)
  • tissue
  • Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue , usually referring to the delivery of blood to a capillary bed in tissue. (wikipedia.org)
  • Perfusion is measured as the rate at which blood is delivered to tissue, or volume of blood per unit time (blood flow ) per unit tissue mass. (wikipedia.org)
  • Measuring tissue perfusion is valuable for diagnosis and treatment monitoring in numerous diseases. (tue.nl)
  • The first part of the perfusion study ( Maarten Heres ) is to examine the feasibility of Photo-acoustic (PA) imaging as a tool for quantitative measurements on tissue perfusion. (tue.nl)
  • : measuring muscle perfusion This technique is very sensitive for the detection of moving blood in deeper lying tissue, such as the skeletal muscles. (tue.nl)
  • The difference between diffusion and perfusion abnormalities provides a measure of the ischemic penumbra or the brain tissue that has been injured but has reversible ischemia. (springer.com)
  • Predicting tissue outcome in acute human cerebral ischemia using combined diffusion- and perfusion-weighted MR imaging. (springer.com)
  • Absolute tissue perfusion, as well as tissue temperature, is displayed graphically as a function of time throughout the measurement sequence. (bio-medicine.org)
  • About 85% of lungs made available for donation are not used due to tissue damage that potentially could be repaired with perfusion or other techniques. (latimes.com)
  • In practical implementation, we develop global fiber tracking that exploits diffusion MRI for reconstructing macroscopic tracts with microscopic properties of the tissue compartments, dynamic measurements of cerebral perfusion and vessel size imaging. (uniklinik-freiburg.de)
  • Prestroke perfusion levels, however, may not be regained in all regions of the brain, leaving uninfarcted tissue hypoperfused well past the acute stage. (hindawi.com)
  • Every increase of ICP can cause a change in tissue perfusion and an increase in stroke events. (wikipedia.org)
  • Minusheet perfusion culture system is used for advanced cell culture experiments in combination with adherent cells and to generate specialized tissues in combination with selected biomaterials, special tissue carriers and compatible perfusion culture containers. (wikipedia.org)
  • Moreover, to always offer fresh nutrition including respiratory gas and to simulate a tissue-specific fluid environment, the tissue carriers can be inserted into compatible perfusion culture containers. (wikipedia.org)
  • SPECT
  • Perfusion of various tissues can be readily measured in vivo with nuclear medicine methods which are mainly positron emission tomography (PET) and single photon emission computed tomography (SPECT). (wikipedia.org)
  • In contrast to the nuclear imaging modalities (PET and SPECT), CMR perfusion does not involve the use of ionising radiation and can therefore be used multiple times without the risk to the patient of exposure to radiation. (wikipedia.org)
  • acute
  • Perfusion imaging is positive immediately following an acute stroke. (springer.com)
  • A settling of these events (e.g., lesion stabilization, reduced inflammation) contributes to recovery of function in acute stroke-induced aphasia, when perfusion is most likely to reverse to prestroke levels, either spontaneously or through pharmacological interventions [ 9 , 10 ]. (hindawi.com)
  • clinical
  • The clinical question that we want to answer is whether the muscle perfusion might be the limiting factor in exercise tolerance for heart failure patients. (tue.nl)
  • Percutaneous hepatic perfusion (PHP) is a regionalized, minimally-invasive approach to cancer treatment currently undergoing Phase II and Phase III clinical testing. (wikipedia.org)
  • measurements
  • Perfusion measurements are taken by comparing the radioactivity of selected regions within the body to radioactivity of blood samples withdrawn at the time of microsphere injection. (wikipedia.org)
  • assessment
  • Tests verifying that adequate perfusion exists are a part of a patient's assessment process that are performed by medical or emergency personnel. (wikipedia.org)
  • The second track of this study is the assessment of skeletal muscle perfusion during exercise, using PD ultrasound. (tue.nl)
  • relate
  • Overperfuson and underperfusion should not be confused with hypoperfusion and hyperperfusion, which relate to the perfusion level relative to a tissue's current need to meet its metabolic needs. (wikipedia.org)
  • With this data, we can track the kinetics of muscle perfusion and relate them to the exercise intensity. (tue.nl)
  • refers
  • Malperfusion can refer to any type of incorrect perfusion though it usually refers to hypoperfusion. (wikipedia.org)
  • sometimes the latter term refers to zero perfusion, but often it refers to any hypoperfusion that is bad enough to cause necrosis . (wikipedia.org)
  • technique
  • The perfusion technique essentially repairs damage caused by swelling or inflammation in the lung, Dark said. (latimes.com)
  • Limb perfusion is a medical technique that is used to deliver drugs locally directly to a site of interest. (wikipedia.org)
  • The main purpose of the isolated limb perfusion technique is to deliver a very high dose of chemotherapy, at elevated temperature, to tumour sites without causing overwhelming systemic damage. (wikipedia.org)
