What is Datscan (Ioflupane I 123 Injection)?
DaTscan is a radioactive drug that is injected into your bloodstream to highlight areas of your brain so that images can be taken with a special camera (called a single-photon emission computed tomography [SPECT] camera). If you are an adult with a movement difficulty, your doctor may decide to order this imaging test, along with other medical tests, to help decide if your movement difficulties are due to a parkinsonian syndrome or a similar condition such as essential tremor.
Types of parkinsonian syndromes are Parkinson’s disease, multiple system atrophy, and progressive supranuclear palsy. DaTscan cannot tell the difference between these parkinsonian syndromes.
DaTscan is available only by prescription and must be ordered by your doctor.

If you have any symptoms of a serious allergic nature, including low blood pressure; trouble breathing; throat tightness; swelling of your face, lips, or tongue; or rash and itching, inform your doctor or go to your nearest emergency room right away
- To help decrease the amount of thyroid accumulation of iodine: Your doctor will give you a medication at least one hour before giving you DaTscan. The purpose of this medication is to minimize the amount of radioactive iodine going into your thyroid gland

- If your are a nursing mother, your doctor will decide whether you should interrupt nursing and pump and discard breast milk for six days after DaTscan administration to reduce the risks to your nursing infant
- If you have kidney and/or liver problems: The effects of kidney and /or liver damage from the use of DaTscan are not certain. DaTscan is removed by the kidney, and patients with severe kidney problems may have increased radiation exposure that could change DaTscan images
- Children: DaTscan should not be given to children
- In clinical studies performed, the most common side effects included headache, nausea and upset stomach, a sensation of motion, dry mouth, or dizziness in less than 1% of patients (1 in 100 patients)
Some drugs may interfere with DaTscan. Be sure to tell your doctor what drugs you are taking so that he or she can decide whether you should stop any of them for a period of time before using DaTscan
Always talk to your doctor if you have any questions about the SPECT imaging procedure or the use of DaTscan
Increase your level of hydration (fluids) prior to and after receiving DaTscan, and to empty your bladder frequently for the first 48 hours following DaTscan administration
