I am having an mri later today and i just smoked a ciggarette. will the doctor find out i smoke through the scan? i started smoking a month or two ago. i don't smoke alot. maybe one a day if that.

No, : No, though smoking dramatically increases your risk of developing cancers in the lung, esophagus, tongue, larynx, and pharynx and also your risk of getting arterial disease. Those things do show up in an mri. Stop now. Smoking has absolutely no redeeming social value, costs a lot of money, and makes you smell bad. It's addictive and, when used as directed, cigarettes have a good chance of killing you. You may only smoke a few now, but that is absolutley guaranteed to iincrease if you don't quit.

Smoking: No he won't find out, but you should tell him that you're smoking . You are obviously worried about it so get some help. This is our emotional response, a shame response to not wanting to tell your doctor everything , this is always dangerous tell him everything and if he doesn't like it find another doctor.
