During (CNO 4cm) sag and trv ultrasound screening last year left lobe nodule measured 6x5x5mm and was solid,however this year meausered by the same machine(CNO 5cm) sag and trv measurement of the same nodule is 3x3mm and again solid.With CNO 4cm measurement nodule picture was enlarged while with CNO 5cm decreased.1.When measuring the length of nodule which ultrasound method is the best(sag or trv)? 2. Is the above nodule measurement from this year decreased,increased or the same compared to one from last year? 3. Which nodule(s) are more dangerous (eventhough there is no significant change in both in the first 5-6 months) and therefore should be followed up more closely either with thyroid ultrasound or biopsy: cystic nodule measuring 10--11 mm in length or solid nodule measuring 5--6 mm in length?Thank you

any nodule/cyst above 10mm (1cm) needs to be considered for FNA biopsy. Solids are more likely cancer than cysts however. The sagital plane is the only way to measure length -- transverse measures width and height - but the measurment looked at is the longest/greatest of any of these 3 dimensions (length, width, height).
Different machines should not vary with regard to accuracy of measuring size of a nodule.
