Benign Thyroid Nodule. A) B-mode US of a patient’s thyroid shows a large solid nodule measuring 47×27 mm in the x - z dimensions on left lobe with a small cystic component, B) Ultrasound C-scan at 2.0 cm depth measuring about 44.2 mm x 30.5 mm in the x-y dimensions, and C) In vivo VA image of thyroid (with 7 L array probe, f 1 = 3.64 MHz and Δf = 54.27 kHz) at 2.0 cm depth which correlates to the one of C-scan plane, measuring more than 47 mm in the x-direction and 30.5 mm in the y-direction and the star shows the dimensions. The VA image is 47 ×50 mm.
