Dermatology

We studied images with the following features:
  • 10K images up to 100K images 
  • The images were taken with a dermatoscope (dermatoscopic)
  • The images of skin lesions
  • The images have a resolution of at least 1080p
  • Each image has an associated diagnosis that was obtained through histopathologic analysis
  • Each image is provided alongside the age and sex of the patient
  • Each image is provided alongside the location of the lesion on the body (e.g. lower left arm)
  • The country from which the image was collected provided
  • Each image is attached to an SOP that details how it was collected and any processing performed

The distribution of different diseases;
  • More than 5% of Melanoma 
  • More than 5% of Basal Cell Carcinoma
  • More than 5% of Squamous Cell Carcinoma
  • ​Less than 70% of Benign Nevus
Neurology

We studied images with the following features:
  • The patient diagnosed with amnestic mild cognitive impairment (aMCI)
  • The patient’s sex and date of birth
  • Mini-mental state exam (MMSE) total score, and exam date
  • Clinical dementia rating sum of boxes (CDR-SB), and exam date
  • T1-weighted brain MRI scan
    • Non-contrast
    • Field strength 1.5T or 3T
    • Resolution up to 1.31 mm acceptable, 1 mm preferred
    • Good GM-WM (gray/white matter) differentiation, no major mass lesion
    • No major image artifacts such as distortion, motion, susceptibility, or aliasing
  • Availability of clinical follow-up confirming either:
  • Diagnosis of Alzheimer’s dementia in any future follow-up visit but no later than 5 years from the time of the MRI scan. Or,
  • The patient remained non-demented for at least 5 years after the MRI scan
We also worked with a dataset of 210 patients which were not yet documented. MR coding, APOE genotype, and homocysteine are also available.
In addition to that a dementia dataset of 530 patients, all of whom were evaluated in at least 3 visits.
In total 2000 patients with various dementia diagnoses (mostly Alzheimer's disease) have their first or second visit.
