Proper preparation is essential to ensure a smooth procedure. Follow these steps before your appointment:

• Stop taking blood thinners.
• Arrange for a driver. 

Positioning is important for a successful procedure:

• After the area is cleansed, the radiologist inserts a needle and injects the contrast dye. You may feel pressure or fullness in the joint, but it is not usually painful. You will then be taken to CT or MRI for your scan.

• Medications: Inform your physician about any medications you're taking. You will be instructed to avoid blood thinners (e.g., aspirin, Bayer Back & Body, Excedrin) prior to the exam.
• Post-Procedure Care: You will need a driver after the procedure due to potential numbness/tingling, discomfort, or other effects that could impair your ability to drive.

While complications are rare, risks include infection, nerve injury, or an allergic reaction to the contrast material.

Mild discomfort is normal. You may take over-the-counter pain medication or prescription medication if provided by your provider. You should plan to take it easy for the rest of the day.
