Address the cause,not the effects.The main source of MRI acoustic noise is thegradient coils. Rapid switching of the gradientsgenerates significant mechanical vibrations, akinto a jackhammer or a loudspeaker at a rock concert.To effectively reduce noise beyond what can beachieved by conventional methods (gradientinsulation, force compensation), the cause of thenoise – sharp gradient switching – must beaddressed directly. The challenge lies in developinga solution that is effective and intelligent and doesnot compromise image quality or scan time.Conventional MRI examinations are accompaniedby sharp gradient switches, producingmechanical vibrations that translate into loud,QuietX1, a unique Siemens innovation, is a smartalgorithm for optimizing gradient switching.QuietX works to provide the best possible gradienttrajectory through intelligent summation ofgradients and reduction of the slew rate, whilemaintaining timing parameters in the same range.The results include significant reductions in acousticnoise and smoother, more pleasant sounds –with no impact on image quality and scan time.unpleasant sounds. QuietX overcomes these soundpeaks by optimizing and smoothing the gradienttrajectory and consequently lowering the noise.Schematic illustration: Conventional and QuietXGradientQuietXConventional

The realization of quiet MRI istruly exciting. It will improveclinical care for many pediatric,dementia and psychiatricpatients, while providing a morecomfortable experience for allpatients. For the many patientsscanned at our hospital, T1weighted PETRA provided thesame diagnostic informationas MPRAGE. PETRA even provideddiagnostic advantages in somecases; for example, paranasalsinuses could be imaged withoutsusceptibility-related distortion.3, 4Dr. Masahiro Ida,Tokyo Metropolitan Ebara Hospital,Tokyo, Japan
