Improve patient outcomes. Increase practice revenue.
Mobile TCD diagnostics that help practices improve patient care, retain referrals, and generate additional in-house revenue.
Advanced Neurovascular Diagnostics Without Sending Patients Elsewhere
Offer advanced cerebral blood flow assessment directly within your practice while improving continuity of care and retaining reimbursable diagnostic services.
What Is TCD Testing?
Transcranial Doppler (TCD) is a non-invasive ultrasound study that measures blood flow velocity within the brain's major arteries. Using Doppler technology, physicians can evaluate cerebral circulation in real time without radiation, contrast agents, or hospital admission.
TCD is commonly used to assess stroke risk, intracranial stenosis, vasospasm, embolic signals, and right-to-left cardiac shunts associated with cryptogenic stroke.
Non-Invasive
No radiation, contrast dye, sedation, or recovery period required.
Clinical Value
Provides real-time hemodynamic data that supports neurovascular decision-making.
Fast & Efficient
Studies are typically completed in 30–45 minutes with rapid reporting available.
Physician Interpreted
Every report is reviewed and signed by a board-certified interpreting physician.
Stroke & TIA
Evaluate cerebrovascular disease and embolic risk.
PFO Detection
Assess right-to-left shunts associated with cryptogenic stroke.
Vasospasm
Monitor cerebral artery narrowing after hemorrhage.
Intracranial Stenosis
Identify abnormal flow velocities suggesting arterial narrowing.
Why Practices Bring TCD In-House
Instead of referring patients to hospitals or outside imaging centers, practices can provide advanced neurovascular diagnostics directly within their office while improving continuity of care and retaining reimbursable services.
Retain Diagnostic Revenue
Keep reimbursable TCD studies within your practice instead of sending patients to outside facilities.
No Capital Investment
Vohanix provides the equipment, certified technician, scheduling support, and operational infrastructure.
Improve Patient Retention
Patients receive testing within your practice, creating a more seamless experience and strengthening long-term continuity of care.
