Abstract
The present teaching aims to detect a lesion in tissue at a very early stage. The present teaching provides a magnetic resonance imaging apparatus including a transmission/reception module that receives a magnetic resonance signal from a subject after transmitting a high-frequency signal, a control module that controls the transmission/reception module such that scans are executed based on pulse sequences corresponding to a first imaging condition without application of an MT pulse and to a second imaging condition accompanied by the application of the MT pulse, a calculation module that calculates a lesion diagnostic rating index represented as a function of a signal intensity Mo of a first magnetic resonance signal received from the subject according to the first imaging condition and a signal intensity Ms of a second magnetic resonance signal received from the subject according to the second imaging condition, and a detection module that detects a lesion in living tissue or a presage thereof in the imaged region based on the lesion diagnostic rating index.
