Value of angiography, sonography, and CT in renal infarction

The value of angiography, sonography, and computed tomography as diagnostic methods for renal infarction is discussed. In all cases the infarct could be demonstrated angiographically, but not by sonography. In the case of a former infarct, the involved area appeared as a tumour mass by sonography and enhanced CT-scan showed contrast enhancement of the mass.
