Thyroid Ultrasound - THANC Guide
Echogenic Foci. Echogenic foci refer to the presence of “bright spots” within the thyroid nodule, which can be seen on ultrasound. The presence of these dot-shaped bright spots or calcifications is indicative of a higher risk of malignancy.
Malignancy risk stratification of thyroid nodules according to ...
2022年10月5日 · In the 2021 K-TIRADS, punctate echogenic foci were defined as punctate (≤ 1 mm) hyperechoic foci within the solid component of a nodule, nonparallel orientation as the anteroposterior diameter ...
TI-RADS - Thyroid Imaging Reporting and Data System
The five ultrasound features of thyroid nodules used in TI-RADS are: composition, echogenicity, shape, margin and punctate echogenic foci. Each item is given points. The points are added from all categories to determine the TI-RADS level, each with a recommendation.
Frontiers | Role of echogenic foci in ultrasonographic risk ...
2022年8月28日 · The patterns of echogenic foci on ultrasonography were classified into the following four categories: punctate echogenic foci, macrocalcification, peripheral calcification, and multiple different types of echogenic foci.
ACR Thyroid Imaging, Reporting and Data System (TI-RADS): …
2017年3月31日 · Punctate echogenic foci are smaller than macrocalcifications and are nonshadowing. In the solid components of thyroid nodules, they may correspond to the psammomatous calcifications associated with papillary cancers and are therefore considered highly suspicious, particularly in combination with other suspicious features.
Tips for improving consistency of thyroid nodule interpretation …
Punctate echogenic foci (PEF) are round and ≤1 mm, while echogenic interfaces havea linear or tram like appearance . Large echogenic foci >1 mm associated with comet-tail artifacts (+0 points) denote colloids, and are benign.
Patterns of Sonographically Detectable Echogenic Foci in …
2017年4月24日 · Our study shows that sonographically detectable echogenic foci in malignant pediatric thyroid nodules can be reliably classified into morphologic patterns on the basis of ACR TI-RADS descriptions, with punctate echogenic foci being the most common subtype.
