Figure 3: Axial T2-w (a), T1-w (b), DW (c), ADC (d), and T1-w DCE (e) images at the same level reveal a hyperperfused lesion with infiltrative edges along the mid and posterior third of the right lateral border of the oral tongue. Note the differences in the DOI measure in each sequence. Though DW (c) and T1-w DCE (e) provide the maximum contrast-to-noise ratio enabling the radiologist to differentiate the pathology from the native normal tissue, T1-w DCE provides the best depiction of the transition zone allowing for a more precise measurement of DOI. ADC: Apparent Diffusion Coefficient, DOI: Depth of Invasion, DCE: Dynamic contrast-enhanced, DW: Diffusion-weighted, T2-w: T2-weighted, T1-w: T1-weighted
