Everything you need to know about Computed Tomography (CT) & CT Scanning


Unique Clinical Scenarios

question1. The patient has sickle cell disease. Can they get IV contrast?
question2. The patient has multiple myeloma. Can they get IV contrast material?
question3. If a patient has thyroid disease is iodinated contrast contraindicated?
question4. If a patient has thyroid cancer is iodinated contrast contraindicated?
question5. If a patient has myathenia gravis should iodinated contrast be used for a chest CT?
question6. If a patient is on glucophage (or other oral diabetes medications) is there an issue with iodinated contrast agents? What is the current rule with oral diabetes drugs? (glucophage)
question7. What patients take glucophage (metformin)?
question8. What is the danger of Metformin and iodinated contrast?
question9. What are the other names for metformin?
question10. What are the current guidelines for patients taking metformin and needing a contrast study?
question11. Is there any problem with using iodinated contrast for CT if a patient is on the cardiac drug Amiodarone?
question12. Can you use iodinated contrast on a patient with suspected or known pheochromocytoma?
question13. If a patient is nursing can she receive IV contrast?
question14. What is our policy for scanning a pregnant patient?
answerAs with any radiology study that uses ionizing radiation, we try to avoid scanning the pregnant patient. The fetus is especially vulnerable in the first trimester. That said, we will scan the pregnant patient if the clinical situation warrants it. Two applications that come to mind include trauma and to rule out pulmonary embolism.
In cases like suspected appendicitis ultrasound should be used first and CT only done when ultrasound does not provide the necessary information.
question15. If a CT is done on a pregnant patient and iodinated contrast is used can that affect the fetus?
question16. Who should get baseline serum creatinine levels before CT?
