Diffusion tensor imaging beyond brains: Applications in abdominal and pelvic organs

Figure 1 Normal images of hepatic diffusion tensor imaging. A: Diffusion image (b value of 0), mainly presenting the anatomic profiles; B: Fractional anisotropy map of the liver, presenting as the pseudo-colored image; C: Apparent diffusion coefficient map of the liver, presenting as the pseudo-colored image as well (Li et al[10], 2015; open access from PlosOne, permission confirmed).

Figure 2 Normal images of pancreatic diffusion tensor imaging. Maps were overlaid on the corresponding T2 weighted image. The direction map presents in three colors the direction of the 1^st principal eigenvector; red: Left to right direction; green: Head to feet direction; and blue: Anterior to posterior direction. Vector map presents in white sticks the direction of the 1^st principal eigenvector (Nissan et al[17], 2014; open access from PlosOne, permission confirmed). FA: Fractional anisotropy; ADC: Apparent diffusion coefficient.

Figure 3 Normal images of renal diffusion tensor imaging. A: Diffusion image (b-value of 0), mainly presenting the anatomic profiles; B: Apparent diffusion coefficient map of the kidneys; C: Fractional anisotropy map of the kidneys, presenting as the pseudo-colored image.
