Purpose: The purpose of this study is to investigate factors influencing strain
sonoelastography findings in evaluation of subcutaneous tumors.
Materials and Methods: Retrospective analysis of sonoelastography findings performed
by two radiologists in 38 consecutive patients with 38 pathologically confirmed
benign subcutaneous tumors was performed. Elastographic finding of the lesions was
graded from 1 (softer) to 3 (harder) according to stiffness. Analysis of correlations
between elastographic findings and height, width and depth of the lesion, and the distance
from bone was performed using the Kruskal-Wallis test.
Results: By reviewer 1, 11 lesions were grade 1 on sonoelastography, eight were
grade 2, and 19 were grade 3, respectively. By reviewer 2, 11 lesions were grade 1 on
sonoelastography, nine were grade 2, and 18 were grade 3, respectively. The distance
from bone differed significantly among the three grades groups for both reviewers;
grade 1, 2, and 3, 0.78 ± 0.75 cm, 1.56 ± 0.68 cm, and 1.77 ± 0.63 cm, for
reviewer 1 (P = .006) and 0.86 ± 0.79 cm, 1.55± 0.72 cm, and 1.74 ± 0.65 cm for
reviewer 2 (P = .016). No significant difference in height, width, and depth of the lesion
was observed among the three groups.
Conclusion: Distance from bone showed a significant association with strain
sonoelastographic findings of benign subcutaneous tumors. |
