[Diagnostic value of the cortico-medullary contrast on dynamic CT and MRI in chronic renal parenchymal diseases].
Correlation between cortico-medullary contrast (CMC) and dynamic CT or MRI for chronic renal parenchymal diseases was evaluated compared with serum creatinine level (Cr). Forty two kidneys of 23 patients were chronic glomerulonephritis (12), chronic pyelonephritis (12), chronic renal failure (4), and other diseases (14). Thirty two kidneys with low Cr (under 1.6) were demonstrated the good CMC by dynamic CT and T1-weighted image (IR) of 0.5 T. Six with middle of Cr (between 1.6 and 3.0) were showed a decrease in CMC and four with high Cr (over 3.0) had no CMC. CMC correlated with Cr.
