Heart-rate sensitive optical coherence angiography for measuring vascular changes due to posttraumatic brain injury in micecal coherence tomography findings in Parkinson’s disease

Traumatic brain injury (TBI) results in direct vascular disruption, triggering edema, and reduction in cerebral blood flow. Therefore, understanding the pathophysiology of brain microcirculation following TBI is important for the development of effective therapies. Optical coherence angiography (OCA) is a …

Coronary dissection or a recanalized thrombus? Optical coherence tomography has the answer

Intra-luminal coronary haziness during coronary angiography can be secondary to ulcerated plaque, spontaneous coronary dissection or a thrombus. During percutaneous coronary intervention, management may differ depending upon the etiology of haziness. Intravascular ultrasound and optical coherence tomography have greatly enhanced …
