Systems and methods for magnetic resonance imaging calibration

A method, comprising:

• performing a first MRI scan of a patient while a biopsy needle is inserted into the patient;
• extracting a sample from the patient using the biopsy needle;
• tagging a first portion of the sample with a first MRI characterization obtained from the first MRI scan;
• tagging a second portion of the sample with a second MRI characterization obtained from the first MRI scan;
• tagging the first portion of the sample with a first histological characterization;
• tagging the second portion of the sample with a second histological characterization;
• performing a second MRI scan of the patient to obtain a third MRI characterization of a region of interest (ROI);
• and
• determining a third histological characterization for the ROI using at least one of:
• the first MRI characterization, the second MRI characterization, the third MRI characterization, the first histological characterization, or the second histological characterization.
