Magnetic resonance imaging (MRI) scans of orthotopic AsPC-1 tumors. (a) A T2W coronal scan was used to determine tumor position and align axial slice markers for tumor slices of interest. The bold dashed line (white) is the “tumor origin” and the smaller dashed lines (red) are a representation of the 1-mm image slices, not drawn to scale. The axial image slices are used for analysis, and a single slice is shown for each scan type: (b) T1W pre-gadolinium (Gd) administration, (c) T1W post-Gd, (d) T1W contrast difference, and (e) T2W.
