周围型小肺癌动态增强MRI与18F FDG PET/CT的相关性初探
A Preliminary Study of Correlation between Dynamic Contrast Enhancement MRI and 18F-FDG PET/CT in Small Peripheral Lung Cancer
摘要
Abstract
Objective: To investigate the correlations of the dynamic contrast enhancement MRI (DCE-MRI) and glucose metabolism determined by the maximum standardized uptake value (SUVmax) at 18F-FDG PET/CT in small peripheral cell lung cancer. Methods: 18F-FDG PET/CT and DCE-MRI wereperformed in 27 consecutive patients with histologically verifiedsmall peripherallung cancer (maximal diameter ≤ 3 cm). The quantitative MR pharmaeokineticparameters including Ktrans, Kep, Ve and SUVmax were measured. Pearson's correlations were conducted between the three MR parameters and SUVmax.Results: Positive correlations were found between Ktrans and SUVmax, Kep and SUVmax (P < 0.05). No significant correlation was found for thecomparison of Ve and SUVmax (P>0.05). Conclusions: Positive correlationswere found between Ktrans and SUVmax, Kep and SUVmax. Combination of three parameters can reflect the malignant feature of lung cancer.关键词
