5. Fractal dimensions of enhanced thyroid rumor.

Abstract

The enhanced CT patterns of the thyroid glands in patient with malignant thyroid tumor were compared with those of benign by measuring the fractal dimensions which were estimated using the box-counting method. The mean fractal dimension was 1.404 ± 0.038 for the malignant tumor and 1.268 ± 0.023 for the benign (P<.001). Concequently, the fractal dimension is useful as a numeric grading of the complexity of the enhanced pattern of thyroid tumor.
