  1. This table presents the main characteristics of all lymph nodes (LN) depicted in 68Gallium-Prostate specific membrane antigen PET-CT including all benign and malignant LN. Count, area, long-axis diameter, short-axis diameter and size-ratio of the LN are presented in the columns. The size ratio is described as quotient of short-axis diameter divided through long-axis diameter. The rows show all LN together and fielded in the six defined anatomical regions iliac left and right, obturator left and right, presacral and inguinal region. Data are given in means and standard deviations.
  2. Abbreviations: LN = Lymph nodes, LAdm = Long-axis diameter, SAdm = Short-axis diameter, SD = Standard deviation.
