Method and system of computer-aided quantitative and qualitative analysis of medical images
First Claim
1. A method of acquiring and analyzing MRS medical image data from a region in an anatomy of a patient, the method comprising the steps of:
- obtaining a plurality of medical image data of the region;
identifying from the plurality of medical image data a set of data points representing a possible lesion in said region;
extracting from the plurality of medical image data features associated with said possible lesion;
computing an initial diagnostic assessment of said possible lesion from said features; and
upon said initial diagnostic assessment satisfying a pre-selected criteria, completing the steps of;
acquiring the MRS medical image data from a candidate region, selection of said candidate region being based on said initial diagnostic assessment and said candidate region being selected to include said possible lesion;
extracting biochemical characteristics from the MRS medical image data;
re-computing a consolidated assessment of said possible lesion further incorporating said biochemical characteristics in said re-computation; and
providing said consolidated assessment to a user for evaluation and modification.

Abstract
A system and method of computer aided analysis of medical images and detection of malignant lesions is described. Medical images obtained from multiple modalities are analyzed. Morphological features as well as temporal, i.e., kinetics features, are combined to compute a consolidated assessment of a possible lesion detected in the medical images. The system includes at least one kinetics module, which is capable of extracting kinetics features from a time sequence of MRI images or MRS data taken after administering a contrast enhancement agent to a patient. The consolidated assessment is presented to a user for confirmation or modification.
