Question

An indication for IV contrast injection is to rule out:

1) mastoiditis
2) sinusitis
3) meningioma
4) Grave's disease

Answer 1

IV contrast injection is commonly used in medical imaging to enhance the visualization of tumors like meningiomas, which is the correct answer for the condition that may require contrast to help in its diagnosis.

Step-by-step explanation:

An injection of IV contrast is often used in medical imaging to enhance the visualization of certain structures or abnormalities within the body. One of the conditions that may require an injection of IV contrast to help in its diagnosis is a meningioma. A meningioma is a type of tumor that arises from the meninges, the membranes that surround the brain and spinal cord. While other conditions listed such as mastoiditis, sinusitis, and Grave's disease may have indications for different diagnostic procedures, the use of IV contrast injection is particularly useful for identifying and evaluating tumors like meningiomas on imaging studies.
