Unrestricted | Published by Siemens Healthineers AG | © Siemens Healthineers AG, 2024 syngo BLADE & SMS BLADE SIEMENS Healthineers What is BLADE? syngo BLADE reduces the motion sensitivity of MR examinations. It’s a technique that incorporates a radial k-space trajectory in the images for all slice orientations. Key benefits: • Improves image quality by reducing motion effects during an MR sequence. This helps to visualize small lesions in non- cooperative patients (e.g., pediatric*, critical, elderly) • Allows scanning under suboptimal conditions due to involuntary motion like pulsation, respiration, etc. • Applicable in all body regions like head, spine, liver, knee Conventional BLADE 3 * The safety of imaging fetuses and infants under two years of age hasn’t been established. You have to decide about the Job Aid Effective Date: 20 Sep 2024 | QR700013568 benefit of the MRI examination compared to other imaging procedures.

The separation of slices is achieved by using different coil sensitivities along the slice direction (as with PAT). To improve the g-factor, use the blipped CAIPIRINHA. Please note: SMS is supported by BLADE Diffusion since > XA50A and for non-diffusion imaging since > XA70A. Key benefits: • More slices • Increase the number of slices with the same scan time using the same TR compared to a standard sequence • Reduced acquisition time • TR decreases or Turbo Factor increases when using the given number of slices compared to a standard sequence 13 Job Aid Effective Date: 20 Sep 2024 | QR700013568 Unrestricted | Published by Siemens Healthineers AG | © Siemens Healthineers AG, 2024 syngo BLADE & SMS BLADE SIEMENS Healthineers SMS BLADE parameter settings > XA70A To activate SMS for non-diffusion imaging from syngo MR XA70A upwards, select SMS in Resolution > Acceleration > Acceleration mode.
