1. A medical image processing apparatus, comprising:
processing circuitry configured to
obtain a medical image;
calculate a first blood flow direction based on a structure of a region of interest rendered in the medical image;
calculate a second blood flow direction based on a structure of a region surrounding the region of interest, the region surrounding the region of interest being different from the region of interest;
determine an angle formed between the first blood flow direction and the second blood flow direction; and
identify information related to a disease risk in the region of interest, based on the determined angle.
