Dynamic contrast enhancement (DCE) MRI is rarely used in lung lesions in previous studies, because of the influence of heart rate and respiratory motion. With the development of 3D non-rigid registration algorithm, high resolution dynamic enhanced MRI application in lung disease is increasing. After registration, the image is more clearer and the quantitative parameters are more accurate. The quantitative parameters Ktrans and Kep are capable of differentiating benign and malignant lung lesions, which has an important value in clinical work.
