Figure 19a. Suprasternal approach with semicoronal scanning. (a) Axial CT scan shows a bilobular retrosternal mediastinal mass (M) between the right brachiocephalic vein (V) and artery (A). (b) Semicoronal CT scan, obtained by placing a pillow under the patient’s shoulders and tilting the CT gantry craniocaudally, shows a direct suprasternal access window, which allows safe placement of a biopsy needle (arrow) into the mass (M). A = brachiocephalic artery, V = right brachiocephalic vein.
