Key result
Three-dimensional fusion imaging without contrast medium is described as a useful technique for preoperative evaluation in patients undergoing carotid endarterectomy.
Case Report
Three-dimensional fusion imaging combining MRA and non-contrast CT provides a potential alternative for pre-operative planning in carotid endarterectomy patients who cannot receive contrast medium.

May offer contrast-free preoperative imaging for CEA; hypothesis-generating and requires prospective validation before adoption.
Carotid endarterectomy (CEA) is a popular surgical procedure for patients with carotid artery stenosis. Before performing CEA, radiologic information about carotid artery stenosis must be obtained using three-dimensional (3D) computed tomography angiography (CTA). However, it is difficult to perform 3D-CTA in patients with renal dysfunction and an allergy to contrast medium. To solve this problem, 3D fusion images (3D-FI) with magnetic resonance angiography and 3D computed tomography are created. In this report, we describe the utility of 3D-FI.

Mizutani et al. (2017) conducted a case report in Carotid artery stenosis. 3D fusion images (3D-FI) with magnetic resonance angiography and 3D computed tomography was evaluated. Three-dimensional fusion imaging without contrast medium is described as a useful technique for preoperative evaluation in patients undergoing carotid endarterectomy.
