[The diagnosis of renal perfusion abnormalities by sequential CT (author's transl)].

Abstract

Abnormalities of renal perfusion can be recognised more readily by sequential CT than by a plain CT scan or after "static" enhancement with contrast medium. Haemodynamically significant stenoses of the renal arteries and total, or partial, infarct can be diagnosed in this way. Intrarenal and capsular collaterals can be recognised by slow contrast accumulation in the infarcted area, or by the development of contrast in the sub-capsular portion of the cortex. Renal cortical necrosis is very well demonstrated by the absence of cortical perfusion; this is seen, for instance, in the DIC syndrome or during rejection after renal transplant.
