Hemodynamic Vascular Analysis
HVA is a non-invasive, low-cost method that measures and interprets a patient’s neurovascular hemodynamics and generates highly specific, actionable reports that can aid in diagnosis and treatment of neurovascular disease. It offers a dramatic advance over current technologies in its ability to deliver this richer information in near real time and can be used to track disease progression and/or response to therapy over time. It has enormous and validated potential for immediate application in both clinical and research settings.
NHSi’s proprietary HVA platform extracts and analyzes data from Transcranial Doppler Ultrasound (TCD), an FDA-approved technology that has been used for over twenty years. HVA reports provide patients, clinicians and researchers with the following:
- Precise measurements of the hemodynamic characteristics of 23 intracranial vessel segments individually and collectively.
- Comparison of those measurements with hemodynamic profiles from a proprietary reference database encompassing both asymptomatic and symptomatic data to determine the presence or risk of specific vascular disorders.
- A basis for monitoring and evaluating disease progression over time and/or response to therapy.
- A set of data interpretable by clinicians and researchers irrespective of their expertise in vascular physiology or hemodynamics.
Clinical data and pilot trials show that HVA aids in the diagnosis and treatment of several prevalent neurovascular conditions. NHSi has focused on these five, with an initial emphasis on the first two: Cognitive Impairment, Sleep Apnea, Carotid Artery Disease, Stroke, and Traumatic Brain Injury
“It (HVA) is safe, non-invasive and inexpensive to use - characteristics that suggest HVA will be seen by clinicians and researchers as a very cost effective and valuable addition to their diagnostic and disease management capabilities.”
