Fig. 3. —Graph shows number of radiologists (maximum of 10) who visually detected lower attenuation in obstructed kidney versus actual percentage of difference in attenuation between acutely obstructed renal parenchyma and unobstructed side in three patients, A, B, and C. When difference in attenuation is great enough for most or all radiologists to detect visually, actual difference is more than two standard deviations (SD) above normal and, thus, a statistically significant finding; 1 SD and 2 SD indicate above-average attenuation difference between normal kidneys.
