What type of CT is used for pyelonephritis?

What does pyelonephritis look like on CT?
The type of emphysematous pyelonephritis can be easily and accurately defined on the basis of CT findings (,31). Findings include parenchymal enlargement and destruction, small bubbly or linear streaks of gas, fluid collections, gas-fluid levels, and focal tissue necrosis with or without abscess (,31,,32).

How is pyelonephritis imaging diagnosed?
Computed tomography (CT) of the abdomen and pelvis with contrast is considered the study of choice in complicated acute pyelonephritis. CT can detect focal parenchymal abnormalities, emphysematous changes, and anatomic anomalies, and can also define the extent of disease.
