This work evaluates optical microangiography (OMAG) as a 3D, in vivo imaging tool for quantifying microvascular blood flow in preclinical models where traditional methods lack capillary‑level resolution. OMAG scanning and analysis protocols were optimized across models of cerebral trauma, stroke, meningeal thrombosis, and diabetic peripheral neuropathy to measure perfusion metrics such as blood volume, vessel density, and flow velocity. Results show that OMAG reliably visualizes and quantifies microcirculatory changes, supporting its use as a noninvasive standard for studying vascular pathology. 000000538 540__ $$fCC BY 000000538 542__ $$fIn copyright - single owner 000000538 650__ $$aWounds and Injuries$$028003 000000538 650__ $$aStroke$$032460 000000538 650__ $$aAngiography$$014747 000000538 650__ $$aMicrocirculation$$022263 000000538 650__ $$aCerebrovascular Circulation$$016382 000000538 650__ $$aDiabetic Neuropathies$$017680 000000538 650__ $$aoptical microangiography 000000538 6531_ $$acerebral circulation 000000538 6531_ $$atrauma 000000538 6531_ $$aperipheral blood flow 000000538 691__ $$aSchool of Medicine$$041369 000000538 692__ $$aDepartment of Biomedical Engineering$$041397 000000538 7001_ $$aJia, Yali$$uOregon Health and Science University$$041354 000000538 8564_ $$97b17f3aa-9f25-4b5a-84af-ad67d52fb9fa$$s3477476$$uhttps://digitalcollections.ohsu.edu/record/538/files/539_etd.pdf$$ePublic$$21192088992f68da8aae65d7a837099c3$$31 000000538 905__ $$a/rest/prod/tb/09/j5/67/tb09j567x 000000538 909CO $$ooai:digitalcollections.ohsu.edu:538$$pstudent-work 000000538 956__ $$aGet Accessible Copy$$uhttps://ohsu.libwizard.com/f/requestaccessibledocument 000000538 980__ $$aTheses and Dissertations
