NCT04334902

Brief Summary

mPDia is a software that has been pre-learned based on a neurodegenerative parkinsonism diagnosis model using Nigrosome 1 MRI images, and clinical decision support system for diagnosing neurodegenerative parkinsonism by automatically analyzing Nigrosome 1 MRI images by assisting the medical team. The specific aims of this study are to evaluate efficacy of mPDia for neurodegenerative Parkinsonism compared to the sensitivity and specificity levels of 18F FP-CIT PET/CT which is currently used to diagnose neurodegenerative parkinsonism.

Outcome Measures

Primary Outcomes (2)

  • Sensitivity of mPDia for the Diagnosis of Neurodegenerative Parkinsonism

    Sensitivity of mPDia in diagnosing neurodegenerative parkinsonism, based on comparison with the golden standard (final clinical diagnosis determined by specialist groups). Sensitivity was calculated as TP/(TP+FN) Sensitivity: 100 x True positive(TP)/ \[True positive(TP) + False negative(FN)\] (%)

    At Visit 2 (within 4 weeks after Visit 1)

  • Specificity of mPDia for the Diagnosis of Neurodegenerative Parkinsonism

    Specificity of mPDia in diagnosing neurodegenerative parkinsonism, based on comparison with the golden standard (final clinical diagnosis determined by specialist groups). Specificity was calculated as True Negative / (True Negative + False Positive) Specificity: 100 x True negative(TN)/\[False positive(FP) + True negative(TN)\] (%)

    At Visit 2 (within 4 weeks after Visit 1)

Sampling MethodProbability Sample
Study Population

(1) Adults over 19 years old (2) 3T nigrosome 1 MRI acquired (3) 18F FP-CIT PET/CT are confirmed to be normal(normal cohort) or abnormal(abnormal cohort)

You may qualify if:

  • Adults over 19 years old
  • T nigrosome 1 MRI acquired
  • F FP-CIT PET/CT are confirmed to be normal
  • The person who visits parkinsonism symptoms but is not or is normal for neurodegenerative parkinsonism
  • Adults over 19 years old
  • T nigrosome 1 MRI acquired
  • F FP-CIT PET/CT are confirmed to be abnormal
  • The person who visits parkinsonism symptoms and has been diagnosed with neurodegenerative parkinsonism

You may not qualify if:

  • Patients with other brain diseases except parkinsonism
  • Who have anatomical abnormality in MRIs etc.
  • Who have other causes of tremor(e.g., thyroid disease)
  • Patients with lesion in basal ganglia(e.g., vascular parkinsonism, hydrocephalus and Wilson's disease)
