Ischemia

Poor perfusion (malperfusion), that is, ischemia, causes health problems, as seen in cardiovascular disease, including coronary artery disease, cerebrovascular disease, peripheral artery disease, and many other conditions.
Ischemia can be partial (poor perfusion) or total.

Blood

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.

Cardiac output

Cardiac inputoutputoutput of the heart
In equations, the symbol Q is sometimes used to represent perfusion when referring to cardiac output.
Because cardiac output is related to the quantity of blood delivered to various parts of the body, it is an important indicator of how efficiently the heart can meet the body's demands for perfusion.

Skin

The most common methods include evaluating a body's skin color, temperature, condition (dry/soft/firm/swollen/sunken/etc), and capillary refill.

Arterial spin labelling

arterial spin labelingArterial spin labeling MRI
Arterial spin labeling (ASL), also known as arterial spin tagging, is a magnetic resonance imaging technique used to quantify cerebral blood perfusion by labelling blood water as it flows throughout the brain.

Myocardial perfusion imaging

myocardial perfusionMyocardial perfusion scanmyocardial imaging
The diagnostic information is generated by provoking controlled regional ischemia in the heart with variable perfusion.

Positron emission tomography

PETPET scanPET scans
This limitation restricts clinical PET primarily to the use of tracers labelled with fluorine-18, which has a half-life of 110 minutes and can be transported a reasonable distance before use, or to rubidium-82 (used as rubidium-82 chloride) with a half-life of 1.27 minutes, which is created in a portable generator and is used for myocardial perfusion studies.

Rubidium-82 chloride

82 Rb-chlorideCardiogen-82radioactive isotope
It is rapidly taken up by heart muscle cells, and therefore can be used to identify regions of heart muscle that are receiving poor blood flow in a technique called PET perfusion imaging.

Cerebral circulation

rCBF is usually measured continuously in time.
This equates to an average perfusion of 50 to 54 millilitres of blood per 100 grams of brain tissue per minute.

Volumetric flow rate

flow rateflowvolume flow rate
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. The SI unit is m 3 /(s·kg), although for human organs perfusion is typically reported in ml/min/g.
