The regional distribution of myocardial clearances of Rb86 has been determined in dogs with intact coronary circulation, as well as in those with acute occlusions of the anterior descending or right coronary artery.

The world's first wiki where authorship really matters. Due credit and reputation for authors. Imagine a global collaborative knowledge base for original thoughts. ... Collateral circulation was detected in 23 of 29 (79%) regions with a positive thallium reinjection effect but in only 1 of the other 7 regions (P < .01) [8].

Blood flows at rest were 1.05 +/- 0.14 and 1.13 +/- 0.15 ml.min-1.g-1 in the subendocardium of the collateral and control regions, We suggest that this limited coronary collateral circulation, which develops in response to gradual coronary occlusion in swine, serves as a model for the human collateral circulation for...

Blood supply to regions of the brain through the collateral circulation occurs with increasing severity of ICA stenosis and occlusion. To what extent collaterals modify the risk of stroke, independently of increasing stenoses, is unknown.

By exclusively labeling the spins within individual intracranial arteries, we can selectively measure the regions of the brain perfused by each artery, including the territories supplied by collateral circulation.11,12 This process of individual labeling is conceptually similar to x-ray angiography,

SUMMARY: We applied regional perfusion imaging (RPI), a new arterial spin-labeling MR imaging method that selectively studies regions of the brain perfused by individual carotid and basilar arteries. ... RPI may be useful to study functional collateral circulation and hence guide therapy in ischemic disease.

Despite decades of study, the functional role of the coronary collateral circulation remains controversial (1–3). Although myocardium supplied by ... The MPS defects were predominantly reversible, suggesting that coronary collaterals preserved myocardial viability in the regions subtended by a total coronary occlusion.

Myocardial Perfusion in Patients With a Totally Occluded Left Anterior Descending Coronary Artery Reinjected by a Normal Right Coronary Artery: The Role of Collateral Circulation; Angiology, August 1, 2008; 59(4): 464 - 468. [Abstract] [PDF];

There is limited and conflicting information about the effect of physical exercise on the coronary collateral circulation in humans, partly because previous studies lacked a quantitative means of assessing collateral channels.
