Journal of Magnetic Resonance Imaging, 2013 MRI has become a reliable tool in medical imaging for assessing morphological and functional details of the human body in a noninvasive manner. Perfusion is an important parameter to assess status and functionality of tissue and organs. This review summarizes the different approaches to measure perfusion based on MRI.

Molecular diffusion and microcirculation in the capillary network result in a distribution of phases in a single voxel in the presence of magnetic field gradients. This distribution produces a spin-echo attenuation.

Current Opinion in Cardiology, 1994
The focus of the reports reviewed in the last year has shifted to "outcomes," perhaps in response to the pressures of national health care reform. With regards to the extracorporeal circulation requisite for complex cardiac repair, emphasis is placed on anticoagulation management, blood use and its systemic effects, cognitive outcome after cardiac ...

Separation of diffusion and perfusion in intravoxel incoherent motion MR imaging.
Radiology, 1988Intravoxel incoherent motion (IVIM) imaging is a method the authors developed to visualize microscopic motions of water. In biologic tissues, these motions include molecular diffusion and microcirculation of blood in the capillary network.

ABSTRACT Thyroid glands maintained by isolated perfusion have been used for studies in metabolism, micro-circulation and tumour angiogenesis. Recent work is described. Thyroid metabolism can be studied for brief periods of 4–5 hours, after which there is progressive parenchymal damage.

Brain dysfunction is a frequent complication of sepsis, usually defined as "sepsis-associated encephalopathy" (SAE). Its pathophysiology is complex and related to numerous processes and pathways, while the exact mechanisms producing neurological impairment in septic patients remain incompletely elucidated.

Effects of perfusate viscosity on the perfused rat kidney
Microvascular Research, 1976Elevation of blood hematocrit has been shown to result in little effect upon renal blood flow despite the resulting elevation in whole blood viscosity (L. Share, Amer. J. Physiol. 171, 159–163, 1952). Perfused rat kidneys were used to study the effects of doubling the perfusate viscosity from 0.858 to 1.768 cP.

THE ISOLATED BLOOD AND PERFUSION FLUID PERFUSED HEART
Pharmacological Research, 2000The isolated heart is deservedly one of the most popular experimental models in cardiovascular research, both in terms of cost and the quality and quantity of data it provides. However, it is a deceptively simple model, capable of throwing many problems in the path of the inexperienced or unwary perfuser.

Normothermic Renal Artery Perfusion: A Comparison of Perfusates
Annals of Vascular Surgery, 1996Hypothermia and preservative perfusates have been used to decrease ischemic renal injury. This study was performed to identify the preservative function of perfusates independent of the effects of hypothermia. Rats underwent 45 minutes of renal ischemia. Rectal and renal parenchyma temperatures were monitored and maintained within 1 degree C of normal.
