Radiofrequency Ablation–Guided Venous Imaging With Intravenous Contrast
This imaging test uses intravenous contrast to visualize veins and assess changes in the area treated with radiofrequency ablation.
["The test helps show how veins and the treated area appear before and after contrast is given."]

What is this test?
This is an imaging study performed in connection with radiofrequency ablation, a treatment that uses heat to destroy abnormal tissue. Intravenous contrast may be used to make blood vessels easier to see and to evaluate changes in the treated area.
Why might I need this test?
Your clinician may use this study to guide a radiofrequency ablation procedure, examine nearby blood vessels, or compare the treated area with its baseline appearance. It can also help assess blood flow and detect complications such as bleeding or impaired venous drainage.
How is the test performed?
The test is usually performed with an imaging scanner. Contrast material is given through a vein, and images are obtained as the contrast moves through the bloodstream. Your care team may also collect baseline and follow-up images for comparison.
How do I prepare for the test?
Follow the instructions provided by your imaging center. Tell the care team if you have had a prior contrast reaction, kidney disease, or an allergy to contrast, and tell them if you are pregnant or breastfeeding. Fasting or medication changes may be required for radiofrequency ablation, depending on the procedure and anesthesia used.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
The images may show the location and extent of the treated tissue, the appearance of nearby veins, and how blood flow changes after the procedure. Abnormal findings can include unintended bleeding, vessel narrowing or blockage, poor drainage, or an incomplete treatment effect. Results should be interpreted by your clinician in the context of your symptoms, examination, and other tests.
