1. Put 1.5 cm3 of 1 % Xylocaine into a 3 cm3 syringe and change the needle to a fresh 27-gauge needle. 2. Squirt a few drops out of the…
Fig. 10.1 Hypoechoic nodules . (a) Transverse view of the thyroid demonstrates a nodule (long white arrow) that is hypoechoic or darker than the surrounding thyroid parenchyma (T) but slightly…
Fig. 11.1 Visual schematic of margin features applicable to thyroid nodules It is relevant at this point to clarify an important concept that particularly strikes novice sonographers and trainees in…
Fig. 6.1 This diagram illustrates the basic idea behind the Doppler effect which describes the situation in which a source of waves (“S”) and a receiver (“R1,” “R2,” “R3,” or…
