Confidence in the vial and far beyond

DaTscan is a radiopharmaceutical used in a brain scan (SPECT) to visualize striatal dopamine transporters assisting in the evaluation of patients with suspected Parkinsonian syndromes (PSs) and suspected dementia with Lewy bodies (DLB). DaTscan does not replace the physician’s clinical diagnosis, but may help support clinical evaluation and improve diagnostic confidence.

DaTscan is a proven diagnostic tool for the evaluation of Parkinsonian syndromes and dementia with Lewy bodies.

While early detection can result in reduced treatment cost and improved clinical outcomes, providing an early and accurate diagnosis can be challenging.

Diagnosis through dopamine transporter (DaT) imaging

Combining clinical assessment with DaT SPECT imaging in the early part of the diagnostic process could reduce overdiagnosis, helping to avoid inappropriate therapy.9
Multiple studies have reported similarly high rates of change in diagnosis with DaTscan imaging.2,4,7 Patients with an abnormal DaTscan were more likely to receive a final diagnosis of PS, while patients with a normal DaTscan were more likely to receive a final diagnosis of non-PS.
Confidence inside the vial and far beyond

Reassurance of clinical value and diagnostic assistance established through multiple clinical trials

1,300+ publications on DaTscan are available, supporting effectiveness, utility and potential impact on patient management.15 Significant evidence base for the imaging results of DaTscan have contributed to its integration into key international guidelines.10,11
DLB diagnosis

The DaTscan difference in DLB diagnosis

Lewy body dementia (LBD) is the second most common neurodegenerative dementia after AD, estimated to affect 1.4 million adults in the US.12,13 LBD includes DLB (dementia with Lewy bodies) and PDD (Parkinson's disease dementia).12

A multicenter, randomized, open-label trial conducted by by Walker et al. in 2015 demonstrated the difference DaTscan can make in DLB diagnosis.14
In this study, only 25% of patients had parkinsonian features, but 43% had abnormal scans.14
  • • 170 people with a clinical diagnosis of possible DLB
  • • 114 received imaging with DaTscan, 56 were a control group
  • • Multicenter, randomized, open-label trial conducted in six European countries
  • • Patients who underwent imaging were far more likely to receive a change in diagnosis; 61% by week 8 and 71% by week 24 in comparison to 4% and 16% for the control group, respectively

IMPORTANT SAFETY INFORMATION for DaTscan (Ioflupane I 123 injection)


DATSCAN is indicated as an adjunct to other diagnostic evaluations for striatal dopamine transporter visualization using single photon emission computed tomography (SPECT) brain imaging in adult patients with:

  • • suspected Parkinsonian syndromes (PS) or
  • • suspected dementia with Lewy bodies (DLB).

Important Safety Information About DaTscan™ (ioflupane I 123 injection)


  • • DaTscan is contraindicated in patients with known serious hypersensitivity to ioflupane I 123


  • Hypersensitivity Reactions: Hypersensitivity reactions, including dyspnea, edema, rash, erythema, and pruritus, have been reported following DaTscan administration.
  • Thyroid Accumulation: DaTscan may contain up to 6% of free iodide (iodine-123). Thyroid uptake of iodine-123 may result in an increased long-term risk for thyroid neoplasia. To decrease thyroid accumulation of iodine-123, block the thyroid gland before administration of DaTscan.


  • • In clinical trials, headache, nausea, vertigo, dry mouth, or dizziness of mild to moderate severity were reported. In postmarketing experience, hypersensitivity reactions and injection-site pain have been reported.


  • • Drugs that bind to the dopamine transporter with high affinity may interfere with the DaTscan image. The impact of dopamine agonists and antagonists on DaTscan imaging results has not been established.


  • Pregnancy: Radioactive iodine products cross the placenta and can permanently impair fetal thyroid function. Administration of a thyroid blocking agent is recommended before the use of DaTscan in a pregnant woman. All radiopharmaceuticals have potential to cause fetal harm. There are no available data on DaTscan use in pregnant women to evaluate for a drug- associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Advise pregnant woman of the potential risks of fetal exposure to radiation with the administration of DaTscan.
  • Lactation: Iodine 123 (I 123), the radionuclide in DaTscan, is present in human milk. There is no information on the effects on breastfed infants or on milk. Advise a lactating woman to interrupt breastfeeding and pump and discard breast milk for at least 6 days after DaTscan administration to minimize radiation exposure to a breastfeeding infant.
  • Pediatric Use: The safety and efficacy of DaTscan have not been established in pediatric patients.
  • Geriatric Use: There were no differences in responses between elderly patients and younger patients that would require a dose adjustment observed in the parkinsonian syndrome studies.
  • Renal Impairment: DaTscan is excreted by the kidney and patients with severe renal impairment may have increased radiation exposure and altered DaTscan images.


  • • The risks of overdose relate predominantly to increased radiation exposure, with the long-term risks for neoplasia. In case of overdosage of radioactivity, frequent urination and defecation should be encouraged to minimize radiation exposure to the patient.

PROCEDURE — Radiation Safety

  • • DaTscan emits radiation and must be handled with safety measures to minimize radiation exposure to clinical personnel and patients.

Prior to DaTscan administration, please read the full Prescribing Information for additional Important Safety Information.
