We demonstrate on the alignment of 250 nodules, that the algorithm is robust to changes caused by cancer progression and differences in breathing states, scanning procedures, and patient positioning.
Some people walk around with gray matter full of nodules or with cortical layers that are upside down.
The incidence of thyroid cancer among nodules with different calcifications patterns were 79%% of nodules with multiple punctate calcifications, 58%% of nodules with a single punctate calcification, 21%% of nodules with coarse calcification, and 22 % of nodules with peripheral calcification.
The number of nodules in each patient with multiple nodules ranged from 2 to 15.
Typical cases are characterised by the association of nodules, cavitary nodules and cystic lesions.
CAD was better in detecting most types of nodules, namely peripheral and non-peripheral nodules, solid nodules, intraparenchymal nodules, and spherical and non-spherical nodules.
Presence of nodules was also recorded.
Sixteen nodules (6.7% of nodules, 9.7% of subjects) grew: nine in subjects with a single nodule and seven in subjects with multiple nodules.
Consistently, the size of nodules mirrored the pattern of nodule abundance in each category.
Significant differences were found in age of patients, diameter of nodules, echogenicity of nodules, calcification of nodules, shape of nodules, halo sign, and vascularity pattern between benign and malignant nodules (all P < 0.05).
