RADIOLOGY: VASCULAR: Case# 46: DIED DURING SCAN. 84 year old female involved in an MVA resulting in massive subarachnoidhemorrhage, subdural hematoma, and cerebral edema. Abdominal CTperformed immediately after head CT. Femoral venous access was usedfor contrast injection. Extremely dense intravenous contrast is seen within the IVC, renalveins, hepatic veins, and right atrium. No intra-arterial contrast or organenhancement is present. The patient arrested just as the injection began and the first few images were acquired. The contrast is seen in the IVC and its branches due to the femoral access used. There was no cardiac output to flush the contrast out of the venous system resulting in the extremely high density.
