Zevalin Study

What is a Zevalin study?

The main purpose of the In-111 Zevalin study is to determine based on its biodistribution, if you may proceed to treatment with Y-90 Zevalin. This treatment is for patients with relapsed or refractory low-grade, follicular or transformed B-cell non- Hodgkin’s lymphoma.

How should I prepare for a Zevalin study?

You must have received a Rituxan infusion within 4 hrs prior to the In-111 Zevalin injection.

How long does the test take?

When you arrive to the Nuclear Medicine Department a technologist will place an intravenous catheter into a vein in your arm. Through this IV you will be given a 10 minute infusion of the radioactive isotope In-111 Zevalin. You will then be able to leave the department, returning 2 -3 days later for imaging. When you return for imaging, the technologist will have you lie on our imaging table and scan your body from head to toe. This scan takes about 30 minutes. The information gained from the imaging is used in determining candidacy forY-90 Zevalin therapy

How soon will the scan results be available?

A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.

It is essential to tell your doctor if you are pregnant or think you might be pregnant before undergoing this scan because of radiation exposure.
