Usually CT scan Kidney Stone protocol does not need contrast. If a problem is discovered in the initial CT scan, one might need additional evaluation.
hi no you don’t .
If the doctor kniws you have a history of kidney stones - I would recommend CT without IV contrast .
Some stones will show up without contrast. However contrast is advised as the scan also looks at the ureters and bladder.
