Advanced vascular imaging's Buerger disease diagnosis transformation — the application of high-resolution computed tomographic angiography, magnetic resonance angiography, digital subtraction angiography, and duplex ultrasonography to characterize the distinctive vascular occlusion patterns of thromboangiitis obliterans (Buerger disease) — enabling earlier, more precise diagnosis of this inflammatory non-atherosclerotic segmental arteritis affecting small and medium vessels of the extremities in young tobacco users, with the Buerger Disease Diagnosis Market commercially shaped by the diagnostic challenge that Buerger disease presents — where no specific biomarker exists, diagnosis relies on clinical criteria combined with characteristic angiographic findings, and the critical imperative of excluding atherosclerosis, autoimmune vasculitis, and hypercoagulable states that can mimic its clinical presentation.

Digital subtraction angiography's diagnostic gold standard role — conventional digital subtraction angiography (DSA) maintaining its position as the diagnostic gold standard for Buerger disease characterization — demonstrating the pathognomonic "corkscrew" collateral vessels, segmental occlusions of tibial and peroneal arteries, normal proximal vessels without atherosclerotic changes, and the distinctive distal small vessel involvement pattern that differentiates Buerger disease from peripheral artery disease attributable to atherosclerosis. DSA's continued clinical primacy in definitive Buerger disease diagnosis — despite its invasive nature requiring arterial catheterization, contrast administration, and radiation exposure — reflecting the diagnostic confidence that anatomical characterization of the distinctive angiographic pattern provides when the clinical diagnosis remains uncertain after non-invasive assessment.

CT angiography replacing conventional angiography — the progressive replacement of conventional DSA with multi-detector computed tomographic angiography for initial Buerger disease vascular characterization — achieving sufficient spatial resolution to demonstrate the characteristic segmental occlusions, distal small vessel involvement, and corkscrew collaterals that distinguish Buerger disease while providing non-invasive, rapid assessment. The CT angiography's additional capability — simultaneously evaluating arterial wall calcification (absent in Buerger disease unlike atherosclerotic PAD) and soft tissue structures — creating a comprehensive vascular assessment tool that efficiently differentiates Buerger disease from atherosclerotic mimics that represent the most important diagnostic alternative in the relevant patient population.

Duplex ultrasound's accessible screening role — high-resolution duplex ultrasonography's emerging role in Buerger disease evaluation — providing real-time assessment of vessel patency, flow characteristics, and wall morphology in distal extremity vessels — creating an accessible, radiation-free, and cost-effective first-line imaging modality that can identify characteristic distal occlusive patterns before progressing to definitive DSA or CTA characterization. The duplex ultrasound's particular value in disease monitoring — where serial assessment of disease progression, collateral development, and response to tobacco cessation interventions provides longitudinal vascular status information without the radiation burden or invasive access requirements of repeated DSA examinations.

As imaging technology continues advancing with higher-resolution CT angiography, MRA with blood pool contrast agents, and photoacoustic vascular imaging entering clinical evaluation, what clinical threshold of angiographic confidence should vascular medicine specialists adopt before committing to a definitive Buerger disease diagnosis — and should international vascular societies develop standardized diagnostic imaging protocols that define minimum angiographic criteria for definitive diagnosis to improve diagnostic consistency across treating institutions?
