Regularly a patient’s creatinine level is an
important factor in determining whether a patient will receive IV
contrast with a CT because it is thought that contrast can harm the
kidneys and could worsen underlying kidney disease.
recent retrospective study compared the rates of worsening kidney
problems between patients who received a CT scan with contrast, a
CT without contrast, and no CT.
study even included patients with creatinines of up to 4 before
study suggested that there is no difference in the rate of
worsening kidney problems between the three groups.
