LUNG CANCER DIAGNOSIS USING MAGNETIC RESONANCE IMAGING DATA OBTAINED AT THREE TIME POINTS

摘要

A malignancy classification method and medium for diagnosing a region of lung tissue based on MRI data are disclosed. The classifying includes: settting time points T₁ and T₂ measured from injection of a contrast agent. T₁ represents a wash-in time point for malignant lung tissue at which a first concentration value of the injected contrast agent is substantially equal to or near a peak for injected contrast agent concentration in the region of lung tissue. Patient concentration values of the contrast agent for the area of lung tissue at time points T₁ and T₂ are obtained, and a malignancy classification for the region of lung tissue is provided by comparing the obtained sample concentration values with a predetermined malignancy profile. A visual representation of the malignancy classification of the region of lung tissue is outputted.
