Pulmonary embolism
Deep venous thrombosis Multi detector-row CT
Thirty-two consecutive patients suspected of having pulmonary embolism underwent multi detector-row CT and were prospectively randomized to one of two intravenous contrast injection protocols. Protocol A (370 mg I/ml, total volume of 100 ml, and injection rate of 3.0 ml/sec) was applied in 15 patients, and protocol B (300 mg I/ml, 150 ml, and 3.0 ml/sec) in 17 patients. In early phase, CT values of the pulmonary artery and left atrium of protocol A were significantly higher than protocol B (P < 0.05). In delayed phase, CT values of the descending aorta, abdominal aorta, and inferior vena cava of protocol B were significantly higher than protocol A (P < 0.05). Venous enhancement of the lower extremities was equal between protocols. Our data suggest that protocol A is superior to protocol B in the diagnosis of pulmonary embolus, but inferior to protocol B in the diagnosis of inferior vena caval thrombus.
