Cystic nodules more often result in a non-diagnostic FNAB due to higher fluid content than solid content in the sample obtained from the nodule. Thyroid Scanning The use of radioisotope scanning has nearly been abandoned in the initial workup of a thyroid nodule. This test is performed by a ...
Methods: Three physicians with varying levels of experience evaluated thyroid nodules on US images, focusing on nodule detection and estimating cystic and solid regions. The outcomes were compared to those obtained from a DSS for comparison. Metrics such as classification match...

One of the most difficult problems for the pathologist is to be confident that a follicular adenoma - usually a benign nodule - is not a follicular cell carcinomaor cancer. In these cases, it is up to the physician and the patient to weigh the option of surgery on a case-by-case basis...
10 Examiners also noted the intraglandular location of each nodule, its structure (solid, spongiform, cystic, mixed), the echogenicity of its solid component, margin characteristics, and the presence of intranodular echogenic foci and flow signals on color Doppler imaging. Thyroid function tests ...
Additionally, the output from the classification phase was also be used to determine the percentage of cystic and solid regions with a given thyroid nodule US image.
