Exploratory Assessment of K-means Clustering to Classify 18F-Flutemetamol Brain PET as Positive or Negative
Zukotynski, Katherine; Black, Sandra E.; Kuo, Phillip H.; Bhan, Aparna; Adamo, Sabrina; Scott, Christopher J.M.; Lam, Benjamin; Masellis, Mario; Kumar, Sanjeev; Fischer, Corinne E.; Tartaglia, Maria Carmela; Lang, Anthony E.; Tang-Wai, David F.; Freedman, Morris; Vasdev, Neil; Gaudet, Vincent C. (Wolters Kluwer Health, 2021)Rationale: We evaluated K-means clustering to classify amyloid brain PETs as positive or negative. Patients and Methods: Sixty-six participants (31 men, 35 women; age range, 52–81 years) were recruited through a multicenter ... -

The Use of Random Forests to Identify Brain Regions on Amyloid and FDG PET Associated With MoCA Score
Zukotynski, Katherine; Gaudet, Vincent C.; Kuo, Phillip H.; Adamo, Sabrina; Goubran, Maged; Scott, Christopher J.M.; Bocti, Christian; Borrie, Michael; Chertkow, Howard; Frayne, Richard; Hsiung, Robin; Laforce, Robert Jr; Noseworthy, Michael D.; Prato, Frank S.; Sahlas, Demetrios J.; Smith, Eric E.; Sossi, Vesna; Thiel, Alexander; Soucy, Jean-Paul; Tardif, Jean-Claude; Black, Sandra E. (Wolters Kluwer Health, 2020-06)Purpose: The aim of this study was to evaluate random forests (RFs) to identify ROIs on 18F-florbetapir and 18F-FDG PET associated with Montreal Cognitive Assessment (MoCA) score. Materials and Methods: Fifty-seven subjects ...
