Important Risk and Safety Information About DaTscan

DaTscan™ (Ioflupane I 123 Injection) for Intravenous Use, CII

DaTscan™ is a radioactive drug that is injected into your bloodstream to help take pictures of areas of your brain using a special camera (called a SPECT). If you are an adult with a movement difficulty that may be a parkinsonian syndrome (PS), your doctor may decide to conduct a SPECT using DaTscan contrast, along with other medical tests, to help decide if your movement difficulties are due to PS or a similar condition known as essential tremor. Some types of PS are Parkinson’s disease, multiple system atrophy, and progressive supranuclear palsy.
