The diagnostic value of dual-energy CTA for visualising below the knee arteries in peripheral arterial disease: A systematic review.

ABSTRACT:

Background

Computed tomography angiography (CTA) of below the knee (BTK) arteries in patients with peripheral arterial disease (PAD) is often challenging due to reduced contrast enhancement and the presence of arterial wall calcifications. Several studies have been published using dual energy (DE) techniques to improve image quality and diagnostic performance of CTA. This systematic review aims to assess diagnostic performance of dual energy CTA (DECTA) in BTK arteries of patients with PAD.

Methods

A systematic literature search was conducted to identify studies reporting on DECTA of BTK arteries. Studies were included if they assessed imaging quality using qualitative or objective parameters, or provided data on diagnostic accuracy. The search was performed in Pubmed, Embas
