Differences Sonata vs Symphony in routine scans

April 04, 2014 04:14

Good day to all colleagues.

I'd like to know main practical differences between Siemens Symphony and Sonata in terms of daily routine use (i.e. heads and spines, no research).
Does Sonata really require more power when used with same image requirements?
Does smaller FOV restrict daily use somehow?
Are any stimulation issues observed in patients?

Best regards, Fedor.

Hi,

Smaller Sonata FOV only could affect with spine studies.
Only on a whole spine or "PET" whole body studies smaller Sonata's FOV affects your work flow.
Even on symphony could be any stimulation. More risk of stimulation with special Sonata sequences.
Sonata was very impresive with advanced cardio application and 3D mouse.
more power???. Planning guide asks/says more power requirements because sonata gradient, it means more power is used with special studies like cardio, neuronal.
Sonata is really more noisy than Avanto with SQ gradients.
your Sonata would be 4 or 8 channels?

Best regards

Sonata is for cardiac so higher gradient is required for thinner slices and faster scan. But the fov is less in z direction is compared to symphony.
Normal imaging it take almost same power if your protocols are same.
when you do spine of a big patient the coverage of fov will be less. For that normally sonata is sold with the option automatic extended table movement. So you can make it two pieces and scan. Otherwise it dont affect much in routine scans. Sonata can make very beautiful scans.
these are application points. For thin slice scans also it give good results.

Sonata can make beautiful diffusion studies. Epi sequences are better.
