  • Patent number: 7567832
    Abstract: One or two sets of time course NMR data are acquired using an EPI pulse sequence in which either or both gradient recalled echo NMR signals and spin-echo NMR signals are acquired after bolus injection of a contrast agent. T2* relaxation rates for GE and T2 relaxation rates for SE are calculated from the acquired NMR signals and are corrected for extravasation of contrast agent into surrounding tissues. The gradient-echo signals and spin-echo NMR signals are employed along with the T2* and T2 relaxation rates to calculate hemodynamic parameter maps which are used as a measure of tumor angiogenesis.
