Studies of cerebral circulation time in man: 1 Normal values and alterations with cerebral vascular disease and tumour in arm-to-retina circulation times

Effect of dexmedetomidine vs. acepromazine–methadone premedication on limb to lung circulation time in dogs

“…For the management of IV anaesthesia induction, the CT from the peripheral vein to brain (very probably the main effector site for rapid loss of consciousness during anaesthesia induction) is of primary importance but the information is technically difficult to obtain (Gotham et al, 1962;Brown et al, 1991). The simple technique used in the present study measures CT, which is a determinant of the subsequent drug uptake into both the lungs and other well-perfused organs as the brain (Upton and Huang, 1993).…”

“…The CT from a peripheral vein to the brain would provide more relevant information regarding induction of anaesthesia but is difficult to measure (Gotham et al, 1962;Brown et al, 1991). In contrast, the CT from a peripheral vein to the lung can be measured easily if an appropriate marker and detection method is used (Okamoto et al, 1995).…”

Feasibility of a silicone vascular phantom replicating real arterial contrast filling dynamics on cerebral angiography: An in-vitro pilot study

“…Each cerebral disease is associated with various patterns of angiographic cerebral circulation time. Based on extensive investigations of cerebral arteriography for diseases, such as atherosclerosis and thrombotic cerebral vascular disease, we observed a considerable delay in contrast opacification of small cerebral arteries [ 18 ]. A prior study on an occlusive ICA lesion suggested that angiographic cerebral circulation time and cerebral vasoreactivity are well-correlated [ 19 ].…”

Fluorescence Angiography and Experimental Carotid Occlusion

“…Also, in two patients they found a delay in the interval between the arterial and venous phases in the eye on the side of an internal Submitted for publication April 3,1968 This study was undertaken to determine the effects of acute common carotid occlu¬ sion on the retinal fluorescence angiography pattern in the rhesus monkey.…”
