This material collects mostly in the liver. It will then flow with bile into the gallbladder and then through the common bile duct to the duodenum or small intestine.</p><p>For the test:</p><ul><li>You lie face up on a table under a scanner called a gamma camera. The scanner detects the rays coming from the tracer. A computer displays images of where the tracer is found in the organs.</li><li>Images are taken every 5 to 15 minutes. Most of the time, the test takes about 1 hour. At times, it can take up to 4 hours.</li></ul><p>If the provider cannot see the gallbladder after certain amount of time, you may be given a small amount of morphine. This can help the radioactive material get into the gallbladder. The morphine may cause you to feel tired after the exam.</p><p>In some cases, you may be given a medicine during this test to see how well your gallbladder squeezes (contracts). The medicine may be injected into the vein. Otherwise, you may be asked to drink a high-density drink like Boost which will help your gallbladder contract.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>How to Prepare for the Test</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
