Figure 2. Typical T2* weighted dynamic contrast-enhanced MRI study in invasive ductal breast cancer. Same patient illustrated in Figures 3–6. 40 ml of intravenous contrast Gd-DTPA was given after the 10th data point. Signal intensity changes for three regions of interest are shown. First pass T2* susceptibility effects cause marked darkening of the tumour with no alteration in signal intensity of normal parenchymal tissue or fat. The first pass and recirculation phases are indicated. Anatomical T2 weighted image and subtraction image of the nadir point for the tumour regions of interest are shown.
