Figure 1.
The signal intensity of the transverse-mesocolon adipose tissue was uniform (white arrow) and consistent with the subcutaneous fat (black arrow) signal on the T2-weighted image.
Figure 2.
The middle colic artery showed on the axial enhancement image (A, long arrow) and on the coronal enhancement image (B, long arrow).
The middle colic vein was shown on the axial enhancement image (A, short arrow) and on the coronal enhancement image (B, short arrow).
Figure 3.
The gastrocolic trunk was shown on the axial enhancement image (A) and on the enhancement coronal image (B).
Figure 4.
The transverse-mesocolon vessels were shown on the coronal SSFSE T2-weighted image (A), enhancement on the coronal image (B), on the axial SSFSE T2-weighted image (C) and enhancement on the axial image (D).
Figure 5.
A 56-year-old female with moderate AP and TMI was Grade II.
The transverse mesocolon showed edema and thickening on a coronal SSFSE T2-weighted image (A), on an axial SSFSE T2-weighted image (B) and on an axial SSFSE T2-weighted image with fat suppression (C).
Figure 6.
A 47-year-old female with severe AP and TMI was Grade III.
The transverse mesocolon showed edema and thickening on a coronal SSFSE T2-weighted image (A). The transverse mesocolon showed effusions on an axial SSFSE T2-weighted image (B) and on an axial SSFSE T2-weighted image with fat suppression (C). The transverse-mesocolon-vessel involvement could be seen on the enhancement of the coronal image (D) and axial image (E).
Figure 7.
A 46-year-old male with mild AP and TMI was Grade I.
Transverse-mesocolon-vessel involvement could be seen on a coronal SSFSE T2-weighted image (A), on an axial SSFSE T2-weighted image (B) and on an axial SSFSE T2-weighted image with fat suppression (C). The transverse mesocolon vessels showed the vessel-lumen expansion and dilated and tortuous lateral-branch small vessels on enhancement of the coronal image (D) and axial image (E).
