Sumario:The authors suggest an analysis of the degeneration of intervertebral disks on human cadavers using magnetic resonance imaging. Nine lumbar spines were collected from fresh human cadavers and resonance images were captured. The images were analyzed and classified according to the degeneration grades, with the authors proposing a subdivision of type IV into IV-a and IV-b. Forty-four intervertebral disks were analyzed and authors found the following distribution: 4,5% type I; 40,9% type II; 32% type III and 18% type IV-a. However, the investigators disagreed with the conclusions in 4,5% of the disks. The authors found that the progressive signal lost in the T2-weighted images may be correlated to disk degeneration. Changes found in the magnetic resonance images must be standardized and classified for providing a better understanding.
