Montage of representative contrast enhanced magnetic resonance venography (MRV) images obtained by 3D fast field echo sequence and displayed as maximum intensity projection inverted images. The upper left hand panel is a coronal plane through the neck and upper thorax. The lower left hand panel is a sagittal plane through the upper thorax. The right hand spliced panel shows images that span the thorax, abdominal and upper thigh regions. Labeled arrows point to the azygous vein, external and internal jugular veins (EJV, IJV), brachiocephalic vein (BCV), superior and inferior vena cava (SVC, IVC) among other vascular structures readily appreciated in these images.
