Advanced noise reduction technologies are present on all MAGNETOM® scanners. Nevertheless, we have continuously strived to develop technologies that will further lower noise without compromising imaging efficiency and quality. With Quiet Suite1, we have addressed the root source – sharp gradient switches – to take noise reduction to a new level. Quiet Suite includes QuietX sequences and the inaudible PETRA as well as optimized protocols for neurological and orthopedic examinations. Experience a broad range of benefits:
“The most common complaint we hear from our patients when having an MRI is the loudness of the acquisition techniques. Siemens Quiet Suite is an essential innovation in improving patient experience and outcomes by significantly reducing acoustic noise during complete MR exams.” 3

Complete, quiet exams for neurology and orthopedics
Experience significant sound reduction from the very first sequence - the localizer - and through an entire clinical examination with 2D and 3D clinical routine sequences. Quiet Suite reduces the need for sedation for certain groups of patients such as children and elderly people, leading to higher patient satisfaction. And at no expense of image quality.
Compare conventional examinations with Quiet Suite:
3D PETRA
Reduction in sound pressure: 97%2
"The realization of quiet MRI is truly exciting. It will improve clinical care for many pediatric, dementia and psychiatric patients, while providing a more comfortable experience for all patients. For the many patients scanned at our hospital, T1-weighted PETRA provided the same diagnostic information as MPRAGE. PETRA even provided diagnostic advantages in some cases; for example, paranasal sinuses could be imaged without susceptibility related distortion."3

“The PETRA sequence generates close to no acoustic noise and the QuietX SWI 20 dB less noise than conventional SWI. The quiet sequences are gentle for children and have been very useful in imaging pediatric patients. They provide a more comfortable scanning environment without compromising image quality.”3
