Sacral Nerve Stimulator Imaging Tips

 

This imaging tips sheet for Sacral Nerve Stimulaor (SNS) insertion was produced following reports of variable iamge quality during this procedure. The problem occurrs mainly on the lateral view because the sacrum is so posterior that when centred in the image there is too much air in the field. This confuses the automatic exposure on older machines and causes 'Flare' or 'White Out' with analogue image intensifiers. Centring lower (less posterior) and use of round collimation help greatly as detailed in the tips sheet below. Click on the link below to download the tips sheet in Powerpoint format.
