The types segmentation disaggregates diagnostic modalities into non‑invasive and invasive categories, each with distinct sub‑types that affect market dynamics. Non‑invasive methods include the ankle‑brachial index (ABI), duplex ultrasound, computed tomography angiography (CTA), and magnetic resonance angiography (MRA). ABI offers a low‑cost, point‑of‑care metric, sustaining high adoption in primary settings, while duplex ultrasound provides real‑time flow assessment, supporting both diagnosis and monitoring. CTA and MRA deliver high‑resolution vascular mapping, attracting specialist centers despite higher capital expenditure. Invasive diagnostics are limited to digital subtraction angiography (DSA), which remains essential for definitive anatomical delineation and therapeutic planning but incurs greater procedural risk and cost. The revenue contribution of each sub‑type aligns with its clinical utility, reimbursement profile, and equipment investment, thereby influencing the overall market size within the diagnostics of peripheral arterial disease segmentation framework.
