Phase-contrast magnetic resonance angiography of foot at 5T ultra-high field strength 5T : Visualization of distal small vessels and enhancement by warm water immersion.

ABSTRACT:

Background

Ultra-high field strength magnetic resonance has been proven to offer improved visualization of the distal intracranial vessels and branches, but its effectiveness for visualization of the peripheral vasculature has not been investigated. We aimed to assess the visualization of distal lower-extremity vessels using three-dimensional phase-contrast magnetic resonance angiography (3D PC-MRA) at 5T field strength in combination with warm water immersion (WWI).

Methods

Participants were prospectively recruited and underwent 3T, and 5T 3D PC-MRA of the feet with and without WWI (water temperature between 40°C and 45°C for a duration of 10 minutes). Patients with suspected lower-extremity peripheral arterial disease underwent computed tomography angiography for lesion id
