Dynamic Arterial and Valsalva-Augmented Venous Phase Multidetector CT for Orbital Vascular Lesions

Abstract

To describe the value and purpose of a new method of dynamic arterial and Valsalva-augmented venous phase CT angiographic assessment of vascular orbital lesions. Description of a dynamic arterial and Valsalva-augmented venous phase multidetector CT protocol currently being used at the institution of the authors for investigation of orbital vascular lesions. Research ethics approval was not required by the institution because this is a 1-case report, with a pictorial review of imaging findings in various representative orbital vascular lesions. One case of a distensible venous malformation depicts the clinical application of the imaging protocol. Key features of the malformation were demonstrated by arterial and venous phases of imaging. This technique is of value in diagnosis and management of vascular malformations of the orbit.
