Diagnostic Consideration

Thoracic CT scans may be performed with or without the intravenous injection of iodinated contrast. Contrast-enhanced thoracic CT scanning is usually performed following injection into an upper extremity vein, with imaging started at 30 to 40 seconds after the injection is begun, depending on the specific application. In this patient, contrast was injected via the right upper extremity, resulting in dense enhancement of the right subclavian vein (and the right brachiocephalic vein on Axial 5 and subsequent images); the left subclavian vein (and left brachiocephalic vein on Axial 5 and subsequent images) remains unenhanced in this patient because imaging was begun before injected contrast had sufficient time to circulate throughout the body and reach the left subclavian vein.
