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?
questionThe ACR "Manual on Contrast Media Version 6.0" addressed two specific situations:
  • Patients with Hyperthyroidism
  • Patients with Thyroid Cancer

Some patients with hyperthyroidism or other thyroid disease (especially those who live in iodine-deficient areas) may develop iodine-provoked delayed hyperthyroidism. This effect may appear 4 to 6 weeks after the intravascular contrast administration in some of these patients. This can occur after the administration of any iodinated contrast media. It is usually self-limited.

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?
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?
