Abstract: Based on the dynamic contrastenhanced MRI (DCEMRI) data routinely acquired from a clinical lung, a new method called FCMB RR was proposed for quantitative analysis. This method was based on the reference region model (RR), and combined with fuzzy Cmean (FCM) and BSpline curve fitting techniques. The proposed FCMB RR method not only solved the limitation of complex blood supply system, but also reduced the effect of noise on the quantitative analysis result. 5 patients with pathologically proven lung cancer were examined using the proposed FCMB RR method to demonstrate the feasibility and effectiveness. A significant difference (P<001) in Ktransbetween tumor tissue and normal tissue was found. It could be concluded that the proposed FCMB RR method could be used for quantitative analysis of typical clinical lung DCEMRI data, and the Ktrans information has reference value for treatment and assesses the lung cancer.
