1. A method of automated diagnosis comprising: producing a first diagnostic image of a region of interest of a subject with a nuclear emission tomography scanner; determining an amount of tracer uptake in the region of interest in a subject; producing a second diagnostic image with a magnetic resonance scanner; determining an amount of blood inflow into the region of interest with the magnetic resonance scanner; aligning the first and second images; consulting a knowledge maintenance engine for data from past imaging scans and diagnoses, the knowledge maintenance engine including an acquisition protocol database, a geometric reference database, a control collective database, and a disease templates database and a quality control processor that ensures internal consistency of the knowledge maintenance engine; and analyzing the first diagnostic image, identifying areas of the first diagnostic image that appear different from images of an asymptomatic control collective.
