Product FAQs

MAGNETOM Trio is suited for clinical or research MR of all organs, since effectively all types of applications will benefit from the increased SNR at 3T on the MAGNETOM Trio.

Through the availability of local coils, MAGNETOM Trio enables all body applications.
Combined with 3Tcare and iPAT, MAGNETOM Trio is the first generation of 3T whole-body machines providing real solutions to potential challenges at 3Twithout image quality compromises.

There are several sites worldwide using MAGNETOM Trios for paediatric imaging with particularly useful results. The higher SNR of the 3T can really make a difference for safer diagnosis of the much smaller anatomical structures in children.

There are more than 90 MAGNETOM Trio sold and 70 installed in the world in the last two years (last update May 2004). Installations are present all over the world, from Brazil, to China, while more than 50% of the installations are in the USA.

iPAT serves three important purposes at 3T.

First, iPAT in single-shot techniques reduces blurring and minimizes susceptibility artefacts – which are typically twice as large at 3T than 1.5T. Therefore, iPAT helps overcoming susceptibility artefacts, for example at the base of the skull and maximizes image quality.

Secondly, iPAT reduces the number of RF excitation pulses and therefore reduces SAR deposited in the patient. For example, iPAT enables increasing the number of slices in the same acquisition time without increased SAR.

Because SNR at 3T is twice SNR at 1.5T, the signal loss associated with iPAT is not so critical compared to 1.5T. This means you can use higher iPAT factors at 3T compared to 1.5T, therefore speeding up your acquisitions and improving image quality of single-shot techniques.

In summary, iPAT at 3T provides best image quality with low SAR and maximal number of slices and allows high acceleration factors while not compromising severely SNR.

Yes. IPAT is a standard feature of MAGNETOM Trio, with acceleration factors up to 4 in 2D imaging.

Leader in RF technology, Siemens offers 8 1 MHz – fully equivalent, RF channels since 1999, as an option on the MAGNETOM Harmony, Symphony and Sonata.
However, MAGNETOM Trio is equipped with 8-channels in standard. Within the context of the 3Tcare initiative, 8 RF channels enable to use the greatest iPAT factors, therefore providing best image quality with low SAR and maximal anatomical coverage.

Yes.

T₁ is longer, therefore necessitating particular optimization of the sequence protocols so that contrast similar to 1.5T is obtained.

In addition, Specific Absorption Rate (SAR – or the energy deposited in the body by the RadioFrequency Coils) increases by a factor of 4, when going from 1.5T to 3T. This means that SAR limits –set for patient safety - are more rapidly reached, needing alternative development to ensure fast imaging with great contrast, and best patient safety. This is the basis for the unique Siemens 3TCare program.

Susceptibility effects associated with fat, the frequency difference between 1H in water and fat, can make fat suppression difficult.

Cost is increased.

There are more than 130 MAGNETOM Trio and Allegra sold and more than 100 installed in the world (last update May 2004). Installations are present all over the world, from Jordan, to Japan, with more than 50% of the installations in the USA.

MAGNETOM Allegra and MAGNETOM Trio have different purposes, which are complimentary. MAGNETOM Allegra pushes the limit of technology to offer best advanced brain applications at an advantageous cost.
MAGNETOM Trio has been optimized for best whole-body applications at 3T.
