From: Thyroid nodule ultrasound: technical advances and future horizons
Transverse images of a 1-cm thyroid isthmus nodule using standard thyroid ultrasound (left) and modified grey-scale map/dynamic range presets (right). Macro- (block arrow) and microcalcifications (arrow) are much more conspicuous with the modified preset, originally designed to detect calcification in breast lesions. A follicular variant papillary thyroid carcinoma containing dystrophic and psammomatoid calcification was confirmed on resection
