  • Processing MRI data for analysis of tumors
    Patent number: 11138729
    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.

  • Dynamic MR imaging of patients with breast cancer—establishment and comparison of different analytical methods for tissue perfusion and capillary permeability
    Patent number: 9046589
    Abstract: The present invention encompasses methods, apparatus, and computer based systems for identifying benign and malignant tumors in tissues such as soft tissues and particularly breast tissue using dynamic contrast-enhanced magnetic resonance imagining (DCE-MRI) and dynamic susceptibility contrast-enhanced magnetic resonance (DSC) imagining of the tumors.
