Of the sequences obtained during standard-of-care MRI, we analyzed T2 fluid-attenuated inversion recovery (FLAIR) sequences obtained after administration of a 0.1 mmol/kg gadobutrol (Gadovist; Bayer Healthcare) with the following image parameters: 4 mm slice thickness, no gap, 10 000 ms repetition time, 106 ms echo time, 2600 ms inversion time, and 130° flip angle. Images were obtained by using either 1.5-T (Avanto, Siemens Medical Solutions) or 3-T (Skyra or Prisma, Siemens Medical Solutions) MR systems.
