Second, seven radiologists with varied experience performed US examinations and US-FNA, and interobserver variability among the radiologists may exist [34, 37]. Less commonly, a doctor may recommend a nuclear thyroid scan. The diagnostic performance of US assessments in the diagnosis of thyroid malignancy according to the underlying parenchymal echogenicity was compared using a logistic regression with the GEE (generalized estimating equation) method. Each US feature of malignant and benign thyroid nodules was analyzed according to underlying echogenicity to evaluate which feature affected the final diagnosis. In response, the thyroid becomes overstimulated and begins to release excess hormones, which causes hyperthyroidism. The mean size of the benign nodules were 16.610.5mm, which was significantly larger than that of the malignant nodules, 11.88.6mm (P<.001). Jin Young Kwak.

So, symmetric mild parenchymal heterogeneity could mean that both lobes of the thyroid are showing some heterogeneity, which could be an early indicator of thyroid inflammation, but since it is mild, I wouldn't assume anything is wrong at this point, unless you have had additional tests other than the ultrasound that indicate a thyroid problem. 1991;72:209213.

Even after excluding the nodules which were diagnosed with lymphocytic thyroditis, microlobulated or irregular margins were still more frequently observed in benign thyroid nodules with underlying heterogeneous thyroid echogenicity than in those with underlying homogeneous thyroid echogenicity. Heterogeneous echogenicity of the thyroid gland is a non-specific finding and is associated with conditions diffusely affecting the thyroid gland. Google Scholar. Iodine is essential for T4 and T3 hormone production. Blood tests can measure the levels of thyroid stimulating hormone and thyroxine, which can indicate if a person has hypothyroidism or hyperthyroidism (overactive thyroid). 1996, 51: 167-169. it says heterogeneous thyroid gland. sharing sensitive information, make sure youre on a federal AJR Am J Roentgenol.

Thyroid glands with heterogeneous echogenicity showed significantly lower specificity, PPV, and accuracy compared to thyroid glands with homogeneous echogenicity, 76.3% to 83.7%, 48.7% to 60.9%, and 77.6% to 84.4%, respectively (P=0.009, 0.02 and 0.005, respectively).
