Blood velocity pulse quantification in the human conjunctival pre-capillary arterioles
Koutsiaris, A. G.; Tachmitzi, S. V.; Papavasileiou, P.; Batis, N.; Kotoula, M. G.; Giannoukas, A. D.; Tsironi, E. (2010)Axial red blood cell velocity pulse was quantified throughout its period by high speed video microcinematography in the human eye. In 30 conjunctival precapillary arterioles (6 to 12 mu m in diameter) from 15 healthy humans, ... -
Elimination of motion, pulsatile flow and cross-talk artifacts using blade sequences in lumbar spine MR imaging
Lavdas, E.; Mavroidis, P.; Kostopoulos, S.; Glotsos, D.; Roka, V.; Koutsiaris, A. G.; Batsikas, G.; Sakkas, G. K.; Tsagkalis, A.; Notaras, I.; Stathakis, S.; Papanikolaou, N.; Vassiou, K. (2013)The purpose of this study is to evaluate the ability of T2 turbo spin echo (TSE) axial and sagittal BLADE sequences in reducing or even eliminating motion, pulsatile flow and cross-talk artifacts in lumbar spine MRI ... -
The importance of ophthalmic artery hemodynamics in patients with atheromatous carotid artery disease
Drakou, A. A.; Koutsiaris, A. G.; Tachmitzi, S. V.; Roussas, N.; Tsironi, E.; Giannoukas, A. D. (2011)Aim. The aim of this paper was to provide an insight on the role of the ophthalmic artery blood flow changes due to significant carotid stenosis and the effects of carotid revascularization on the eye and cerebral circulation. ... -
A slit lamp based imaging system for measuring blood velocity in the conjunctival microcirculation of the human eye
Koutsiaris, A. G.; Tachmitzi, S. V.; Kotoula, M. G.; Karabatsas, C. H.; Tsironi, E.; Batis, N.; Chatzoulis, D. Z. (2006) -
A velocity profile equation for blood flow in small arterioles and venules of small mammals in vivo and an evaluation based on literature data
Koutsiaris, A. G. (2009)An empirical parametric equation with 2 bluntness parameters was introduced for describing the velocity profile of blood in the small arterioles and venules of small mammals, in vivo, with the basic approximations of the ... -
Volume flow and wall shear stress quantification in the human conjunctival capillaries and post-capillary venules in vivo
Koutsiaris, A. G.; Tachmitzi, S. V.; Batis, N.; Kotoula, M. G.; Karabatsas, C. H.; Tsironi, E.; Chatzoulis, D. Z. (2007)Understanding the mathematical relationships of volume blood flow and wall shear stress with respect to microvessel diameter is necessary for the study of vascular design. Here, for the first time, volume flow and wall ...
