Single-phase bilateral low dose contrast medium injection for diagnosing occlusions of the thoracic venous system: a case report


Svensson, Anders; Brismar, Torkel B; Morsbach, Fabian (2018). Single-phase bilateral low dose contrast medium injection for diagnosing occlusions of the thoracic venous system: a case report. Acta Radiologica Open, 7(6):2058460118778060.

Abstract

Occlusion of the thoracic venous system and/or occlusion of central venous catheters (CVC) of unknown cause can, in selected cases, require advanced imaging. Here, we describe a case study of a patient with a failing central dialysis catheter (CDC) which was diagnosed by computed tomography (CT) in connection with a single-phase bilateral low-dose contrast medium (CM) injection using only 3.6 g of iodine. By injecting a low CM dose, the risk of streak artifacts from first-pass of high intravascular concentrations of CM can be avoided. Therefore, the technique described here should be beneficial also to patients with normal renal function.
