Abstract:
Ga-DOTATATE imaging for meningiomas is gaining clinical use for selecting patients that may benefit from targeted therapy (eg, Lu-DOTATATE). We present an image of a 67-year-old man with an intracranial WHO grade III anaplastic meningioma. He underwent tumor resection followed by intensity-modulated radiation therapy but experienced a recurrence 25 months later. He received an F-(FDG) and Ga-DOTATATE PET/MR to evaluate for the presence of somatostatin receptor expression and guide subsequent treatment. The scans showed both concordant and discordant regions of uptake, indicating that high somatostatin receptor (SSTR2) expression may not coincide with areas of increased metabolic rate.

Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
