CCI RVS Review 2025/2026 – 100+ Correct Questions with Rationales | Doppler Physics, Carotid Duplex, Venous Disorders, ABI, Portal Hypertension & Vascular Anatomy

This advanced exam prep guide provides over 100 accurate and up-to-date questions with explanations aligned to the 2025/2026 CCI RVS (Registered Vascular Specialist) credential. It focuses on real-world clinical reasoning and board-style multiple-choice questions, equipping sonographers with practical insight into non-invasive vascular testing and ultrasound interpretation. Key areas covered include: Doppler Ultrasound Principles: Frequency shift, blood cell velocity, absorption vs. penetration, lateral resolution, and Doppler signal changes with respiration Cerebrovascular Testing: Vertebrobasilar insufficiency symptoms, carotid duplex ICA/CCA ratios, bruit localization, intima-media thickness Peripheral Arterial Disease (PAD): ABI interpretation, claudication, rest pain physiology, exercise testing, and resistance mechanisms Venous Insufficiency & DVT: Trendelenburg positioning, Valsalva effects, venous valve function, post-thrombotic syndrome, subclavian vein limitations Portal & Hepatic Circulation: Signs of portal hypertension, splenic/mesenteric rerouting, TIPS, and hepatic venous flow Vascular Pathologies & Syndromes: Aneurysms, embolism, Marfan syndrome, thoracic outlet syndrome, Budd-Chiari, and ischemic stroke causes Ultrasound Instrumentation & Artifacts: PPG application, spectral waveform changes, compression techniques, CW Doppler hemodynamics This resource is especially valuable for students in vascular technology programs, diagnostic medical sonography training, and practicing sonographers preparing to sit for the CCI RVS board exam. Relevant for: Courses: Vascular Sonography, Non-Invasive Vascular Imaging, Advanced Doppler Techniques Programs: CCI RVS Certification, ARDMS RVT Exam Prep, Cardiovascular Technology Students and Professionals: Vascular sonographers, ultrasound techs, clinical interns, vascular lab trainees, board exam candidates Keywords: CCI RVS 2025, vascular ultrasound, Doppler physics, ABI testing, carotid duplex, venous insufficiency, portal hypertension, ICA CCA ratio, rest pain, arterial resistance, waveforms, PPG, Marfan syndrome, spectral Doppler, thrombosis, subclavian artery, thoracic outlet syndrome, venous reflux, blood flow dynamics, diagnostic sonography, compression ultrasound
