I have diabetes . I am 59 years old. I have a slightly elevated creatinine level of 1.6, and I would like to check if it is safe for me to undergo a chest contrast test? As I had done CT scan and some white  patch is shown in chest and Diagnostic center suggest me to go for contrast so, are there any precautions that I should take? Alternatively, based on my specific condition, what would be the safest and most effective way to proceed with imaging? Are there any non-contrast imaging alternatives that could provide similar information for my diagnosis?
