Figure 24.11 A 14-year-old female DSH presented for uncontrolled diabetes of nine months duration. (a,b) All portions of the
pancreas (arrows) are enlarged and hypoechoic with ill-defined hypoechoic nodules. The adjacent omentum is reactive. Fine needle
aspiration of the pancreas revealed mild to moderate suppurative inflammation consistent with pancreatitis.

ill-defined hypoechoic nodules. (b) Several hypoechoic nodules are more clearly identified within the pancreatic parenchyma.

ultrasound contrast administration, the pancreas was eval-
uated using color and power Doppler to determine if the
vascularity was altered in cats with pancreatitis. Power
Doppler was more sensitive than color Doppler for determi-
nation of vascularity of the pancreas without contrast. In
those cats with pancreatitis, increased vascularity was
noted in the postcontrast power and color Doppler images
of the pancreas compared to the precontrast images [13].

24.6.1.4 Computed Tomography (CT)
A CT study was done comparing ultrasound and fPLI with
histologic samples from 21 cats suspected to have pancrea-
titis and eight normal controls. CT studies were found to
be insensitive for the diagnosis of pancreatitis in feline

appears reactive. The pancreas (measured between cursors) is enlarged pancreatitis but sensitivity was significantly lower with
