Abstract
Dynamic contrast enhanced MRI data and dynamic susceptibility contrast MRI data for a volume of the patient's body including a tumor are used in order to identify the risk of lymph node metastasis. A volume of interest enclosing the tumor is identified and the MRI data for the volume of interest is processed in order to identify one or more parameters relating to the transverse relaxation rate and/or to dynamic changes in the transverse relaxation rate. A comparison is made to previously obtained similar parameters for other patients having similar tumors that are either known to exhibit lymph node metastasis or are known not to exhibit lymph node metastasis in order to determine if the MRI data indicates that the patient has a tumor at greater risk of exhibiting lymph node metastasis or a tumor with a lesser risk of exhibiting lymph node metastasis.
