Quantitative Assessment of Lower-limb Perfusion for Patients with Peripheral Artery Disease

Abstract

Diagnostic procedures of noninvasive assessment for patients with peripheral artery disease (PAD) have been advancing for decades. Among diagnostic imaging modalities, lower-limb perfusion (LLP) planar scintigraphy and SPECT/CT are exclusively used for diagnosing lower-limb ischemia, therapeutic efficacies, and risk stratification in PAD patients. Of these modalities, LLP SPECT/CT particularly shows more accuracy in providing quantitative assessment of LLP using innovative imaging devices and dedicated software.
