Regadenoson, sold under the brand name Lexiscan among others, is an A 2A adenosine receptor agonist that is a coronary vasodilator that is commonly used in pharmacologic stress testing. It produces hyperemia quickly and maintains it for a duration that is useful for radionuclide myocardial perfusion imaging . [ 1 ]
Pharmacologic agents such as adenosine, regadenoson (Lexiscan), or dipyridamole is generally used when a patient cannot achieve adequate work level with treadmill exercise, or has poorly controlled hypertension or left bundle branch block. However, an exercise stress test may provide more information about exercise tolerance than a ...

Gait recognition is a type of behavioral biometric authentication that recognizes and verifies people by their walking style and pace. [ 25 ] [ 26 ] Advances in gait recognition have led to the development of techniques for forensics use since each person can have a gait defined by unique measurements such as the locations of ankle, knee, and hip.
The most basic way to use the START classifications is to transport victims in a fixed priority manner: immediate victims, followed by delayed victims, followed by the walking wounded. [2] More detailed secondary triage systems such as SAVE may also be used: in this case, the START classifications are used to determine the order in which ...
Perfusion is the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. [1] The practice of perfusion scanning is the process by which this perfusion can be observed, recorded and quantified. The term perfusion scanning encompasses a wide range of medical imaging modalities. [2]
