While the exact mechanism remains unknown, it is likely that microvascular ischemic insults lead to intrinsic changes of the third nerve that may result in enhancement and persistent T2 signal. Additional workup for inflammatory causes of 3NP may not be required when enhancement of the ...
螖R2鈥撐擱2*-MRI-derived vessel size index (VSI) and density indices (Q and MVD) mapped morphological changes of microvessels occurring in subcortical ischemic edema lesions. In cortical ischemic edema lesions, significantly dilated pial veins (p鈥鈥051) and thinned pial arteries (p鈥鈥096) ...

DWMH arises from ischemic changes disorders in the brain [37]; it is linked with neuropathological changes caused by disruptions in nerve fibers which result in ischemic changes [38]. OCTA reports on dementia patients showed reduced SVC and DVC densities and enlarged FAZ area, which are ...
In this animal cardiac arrest study, we applied a CHS hemometabolic model to assess cerebral hemodynamics and metabolism during CA and CPR, with a particular focus on microvascular-level physiological changes. Our main conclusion is that the CHS hemometabolic model could explain the observed changes...
Structural pathologies such as tumors or cysts of the cerebellopontine angle, and demyelination or ischemic lesions of the brainstem should also be considered in the differential diagnosis. Secondary causes of trigeminal neuralgia should be sought if any of the foll...
The remaining 2 cases had CFR of 1.9 and 2.0 with stress perfusion of 2.0 ml/min/g, well above the ischemic threshold of 0.83 ml/min/g associated in other patients with angina and ST-segment changes (FDA 510(k) number 171393). All 7 cases had ≥70% of the LV with high CFC, no ...
The contribution of microvascular injury in causing anatomic myocardial “no-reflow” was first described in the 1970’s[1–3]. At that time, it had already been recognized in other organs that despite recanalization or restoration of arterial flow to an ischemic tissue bed, perfusion at the ti...
The primary outcome (extent of microvascular obstruction on MRI within days 2 through 7, as % of left ventricular mass) was compared between groups using a stratified Wilcoxon test (van Elteren test), stratified by the location of the MI. Ninety-five percent confidence intervals for between-gro...
