There may be considerable differences between sonologists in estimating the size of large goiters or nodules. (13A) One investigation has reported that curved-array transducers may avoid significant inter-observer variation that may occur when linear-array equipment is employed, especially when the gland is very large (14). The inter-observer variation may be almost 50% even among experienced ultrasonographers , because it is difficult to reproduce a two-dimensional image plane for multiple studies (15). Accuracy in volume estimation becomes most important when one uses ultrasound measurements to calculate an isotope dose or to compare changes over time in the size of a nodule or a goiter. Indeed, it has been suggested even for well-defined nodules, a change of less than 1 cm in size should not be accepted as a real change. (13A) The important thing is that the clinician must be guided by the constellation of risk factors, local anatomy, and intervening events, when making a management decision. Stability of size is one factor, but a major one.

Very gently massaging the area and applying heat may encourage blood flow and relieve pain according to the gate control theory of pain , although causing additional pain may indicate the massage is exacerbating the injury.  As for most injuries, these techniques should not be applied until at least three days following the initial damage to ensure all internal bleeding has stopped, because although increasing blood flow will allow more healing factors into the area and encourage drainage, if the injury is still bleeding this will allow more blood to seep out of the wound and cause the bruise to become worse.
