Method, system and/or computer readable medium for improved magnetic resonance (MR) imaging-based tractography

A computer-implemented method, comprising:

• controlling gradient coils and RF transmit coil of an MR imaging system based on a first sequence that includes a PGSE acquisition and an OGSE acquisition;
• processing first MR signals generated in response to the PGSE and OGSE acquisitions and received by an RF receive coil of the MR imaging system to generate a first ADC map for the PGSE acquisition and a second ADC map for the OGSE acquisition;
• and
• generating a seed point map based on the first and second ADC maps, wherein the seed point map visually distinguishes tumor and vasogenic edema.

A computer readable storage medium encoded with computer executable instructions, which when executed by a processor, causes the processor to:

• control gradient coils and RF transmit coil of an MR imaging system based on a first sequence that includes a PGSE acquisition and an OGSE acquisition;
• process first MR signals generated in response to the PGSE and OGSE acquisitions and received by an RF receive coil of the MR imaging system to generate a first ADC map for the PGSE acquisition and a second ADC map for the OGSE acquisition;
• and
• generate a seed point map based on the first and second ADC maps, wherein the seed point map visually distinguishes tumor and vasogenic edema.
