Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Summary of Sensitivity of the Blinded Visual PET Image Interpretations Without Anatomic Images. [ Time Frame: Post flutemetamol administration ]
    Statistical analysis of summary of the blinded visual PET Image Interpretations without Anatomic Images. This data consists of image interpretations by 5 Readers and No subjects were dosed in this study. These Readers examined the PET images for evidence of amyloid plaque.

  2. Summary of Specificity of Blinded Visual PET Image Interpretations Without Anatomic Images. [ Time Frame: Post flutemetamol administration ]
    Statistical analysis of summary of sensitivity of blinded visual PET image interpretations without anatomic images. This data consists of image interpretations by 5 Readers and No subjects were dosed in this study.These Readers examined the PET images for evidence of amyloid plaque.


Secondary Outcome Measures :
  1. Inter-Reader Agreement of PET Images Without Anatomic Images [ Time Frame: Post Flutemetamol Injection ]
    Statistical analysis of Inter-Reader Agreement of PET Images without anatomic Images. This data consists of image interpretations by investigators and No subjects were dosed in this study.
