顯影劑（Contrast dye）具有腎毒性。若病人服用二甲雙胍（Metformin），顯影劑可能誘發急性腎衰竭，進而導致致命的乳酸中毒（Lactic acidosis）。因此，常規指引要求在診斷測試前 24-48 小時停藥，並待腎功能恢復後才恢復用藥。這是糖尿病病人進行放射檢查時最關鍵的風險管理。
Contrast dye is nephrotoxic. In a client taking metformin, contrast may precipitate acute kidney injury and lead to fatal lactic acidosis. Standard guidelines require holding metformin 24-48 hours before and after contrast administration and resuming only after renal function returns to baseline. This is the most critical risk-management measure for diabetic clients undergoing imaging.
