Abstract
- 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.
