Abstract:
Objective To evaluate hepatic enhancement technology with MRI and its clinical application.Methods 147 patients underwent enhanced MRI scanning and an automatic injector.Total dose of contrast agent for each patient was 10 to 15ml(0.2mmol/kg)at a rate of 2ml/s,Two-phase enhancement were performed at a delay of 30 and 70 seconds respectively after the initiation of bolus injection.Results Good visualization of two phases for both hepatic artery and portal vein were achieved in 147 patients in addition to branches of abdominal aorta,hepatic artery,splenic artery,portal vein,inferior vena cava and vasculatures in hepatic port.The 4 patients did not have ideal two-phase images for various reasons.Conclusion MRI with bolus injection using an automatic injector can satisfy the diagnosis for hepatic diseases.
