MR can be used to predict the efficacy of targeted
drugs before operation of renal carcinoma with tumor thrombi. Tumor and thrombi with more abundant
blood supply tend to be more sensitive to drugs. It is
helpful to evaluate the range of tumor thrombus invading IVC wall more
accurately.
The axial contrast-enhancement image shows the
tumor thrombus after using targeted drugs (figure 4)shrinking compared with before medication(figure
3) and invading the right side wall of IVC.
