[Ultrasonography of thyroid cancer].
The diagnosis and management of follicular carcinoma of the thyroid gland remains a controversial topic. Color-Doppler (CD) imaging has been expected for the differential diagnosis between follicular adenoma and follicular carcinoma. CD imaging examination of follicular tumors has revealed that high-velocity pulsative blood flow penetrating the tumor is a characteristic finding of follicular carcinoma. Real-time tissue elastography (RTE), which enable to demonstrate the tissue elasticity, has begun to be applied for the thyroid disease. In follicular cancer, the difference of elasticity from core of the tumor and periphery is supposed to be depend on the difference of hypercellurality. RTE can provide new useful information for the differential diagnosis of thyroid follicular lesions.
