DaTscan


IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS: DaTscan is contraindicated in patients with known hypersensitivity to the active substance, any of the excipients, or iodine.

PRODUCT INDICATIONS AND USE: 
DaTscan is a radiopharmaceutical indicated for striatal dopamine transporter visualization using single-photon emission computed tomography (SPECT) brain imaging to assist in the evaluation of adult patients with suspected parkinsonian syndromes (PSs). DaTscan may be used to help differentiate essential tremor from tremor due to PS (idiopathic Parkinson’s disease [PD], multiple system atrophy [MSA], and progressive supranuclear palsy [PSP]). DaTscan is an adjunct to other diagnostic evaluations. DaTscan was not designed to distinguish among PD, MSA, and PSP. The effectiveness of DaTscan as a screening or confirmatory test and for monitoring disease progression or response to therapy has not been established.

CONTRAINDICATONS: DaTscan is contraindicated in patients with known hypersensitivity to the active subsctance, any of the excipients, or iodine.

 

DaTscan Provides Visual Clarity

Visualization of striatal DaT distribution can aid in the clinical diagnosis of PS, including1,2:

Important Risk and Safety Information About DaTscan: In clinical trials, reported adverse events consisted of headache, nausea, vertigo, dry mouth, or dizziness. These reactions were of mild to moderate severity. In postmarketing experience, hypersensitivity reactions have been reported, generally consisting of skin erythema and pruritus. Injection-site pain also has been reported. To decrease thyroid accumulation of iodine 123, block the thyroid gland at least one hour before administration of DaTscan; failure to do so may result in an increased long-term risk for thyroid neoplasia.

How It Works

  • Motor symptoms of parkinsonian syndromes are associated with striatal dopaminergic neuron loss1-3,7
  • DaTscan binds presynaptically to striatal DaT and, when used with SPECT, may identify dopaminergic integrity2,4,5,8
  • Differentiation between normal and abnormal scans is assessed by the extent (as indicated by shape) and intensity of the striatal signal following DaTscan administration and SPECT scanning2,6,7,9
