# Nuclear medicine in El Paso

Desert Imaging does nuclear medicine in El Paso at its Central center, 7812 Gateway Blvd. East. These scans show how an organ works, not just how it looks: bone, thyroid, kidney, gallbladder, stomach and heart studies, plus I-131 thyroid treatment.

## What it is

Nuclear medicine uses a tiny amount of a radioactive tracer, given by injection, capsule or breath, that travels to a particular organ. A gamma camera picks up the energy it gives off and turns it into pictures of how that organ is working.

Because it shows function, nuclear medicine often finds a problem early, before it changes the shape of an organ enough to show on other scans. Doctors order it for bone pain and infection, gallbladder and liver problems, kidney function, how fast the stomach empties, thyroid and parathyroid disease, and blood flow to the heart.

Some thyroid conditions are treated with nuclear medicine as well. Radioiodine, I-131, is given as a capsule and taken up by the thyroid.

**Good to know:** Nuclear medicine needs a doctor's order, and your insurance may need to approve it first.

## Where to get it

- [Central](https://desertimagingcenters.com/locations/central/nuclear-medicine): 7812 Gateway Blvd. East, Suite 120, El Paso, TX 79915. Monday to Friday, 7 a.m. to 10 p.m. Closed Saturday. Closed Sunday.

## What to expect

Wear loose clothing. Preparation depends on the scan. Bone, liver and spleen scans need none. Gallbladder, gastric emptying, thyroid uptake and stress tests need an empty stomach, and some need you to hold certain medications. We go over your list when you book.

Many scans happen in two visits on the same day, or on two days. For a bone scan you get the injection, leave, and come back in 2 to 3 hours for pictures. For thyroid uptake you swallow a capsule and return at 4 hours and at 24 hours. The camera itself is quiet, does not touch you and gives off no radiation of its own. You lie on a bed while it sits a few inches above you.

A board-certified radiologist reads the study. The report goes to your doctor and to your patient portal.

**How long it takes:** Depends on the scan, from 30 minutes to a full day in two visits.

## Common questions

### Is the tracer safe?

The amount is very small, a few drops, and the tracer is chosen to be safe and approved by the FDA. Reactions are rare. Tell us if you are pregnant or breastfeeding.

### Why do I have to come back for pictures?

The tracer needs time to collect in the organ being studied. For a bone scan that is 2 to 3 hours, for a thyroid uptake it is 4 hours and again at 24 hours. The wait is part of the exam.

### How long does a nuclear medicine scan take?

It depends on the scan, counting the wait for the tracer. A renal scan takes about 30 minutes and a liver and spleen scan about 45 minutes. A HIDA scan takes up to 2 hours and a gastric emptying study about 2 hours. A bone scan takes about 4 hours from injection to the last picture, and a nuclear stress test 4 to 5 hours. A parathyroid scan takes pictures at 10 minutes and at 3 hours, and a thyroid uptake at 4 hours and 24 hours.

### What do I bring for a gastric emptying study?

A meat burrito. The tracer goes in the food and the camera follows it through your stomach. Nothing else to eat or drink after midnight, and no Nexium or insulin that morning.

### Do I stop my thyroid medication?

For a thyroid uptake and scan, yes, for 4 to 6 weeks before, and no iodinated contrast for at least 2 weeks before. Nothing to eat for 6 hours. Do not stop any medication without talking to the doctor who prescribed it.
