The aim of this study is to investigate the role of [68 Ga]Ga-PSMA-11 PET radiomics for the prediction of post-surgical International Society of Urological Pathology (PS ISUP) grade in primary prostate cancer (PCa).Methods. This retrospective study included 47 PCa patients who underwent [68 Ga]Ga-PSMA-11 PET at IRCCS San … The singular values (in Σ) are the square roots of the eigenvalues of the matrix X X. Each eigenvalue is proportional to the portion of the "variance" (more correctly of the sum of the squared distances of the points from their multidimensional mean) that is associated with each eigenvector. The sum of all the eigenvalues is equal to the sum of the squared distances of the points from their multidimensional mean. PCA essentially rotates the set of points around their …
