This will vary depending on the position of the lump.
The main thing is to have plenty of gel !!
Try to get the patient to sit or stand in a position that it can be easily felt.
Make sure the patient and the sonographer are comfortable.
Usually the patient knows where the lump is and can tell the sonographer how it is best felt. If the patient does not know where the lump is because they did not feel it only their Doctor did, then a phone call to the practitioner may need to be made if no lump can be located.
Basic Hardcopy Imaging
The lump must be shown in 2 planes at 90 degrees to each other.
It must have a colour Doppler box put over the entire region to assess for flow. Also a spectral waveform is helpful to check for arterial or venous flow.
An image close to an known organ or tissue plane, labelled with a body marker. Sometimes a measurement from a landmark is useful. EG from the umbilicus or sternal notch etc is helpful .
