RadiAnt DICOM Viewer - Discussion Forum

I have tried several kinds of workstation, unfortunately, there is no one could do subtraction of DSA files. Can your workstation do it?
Kind regards

Currently there is no subtraction feature in RadiAnt. However, I am sure that in the future we will add the DSA functionality.

I find subtraction useful in MR studies as well...
sometimes I need to subtract pre-contrast and post-contrast images in cases of T1 hyperintense lesions. Only subtraction really tells you if it takes gadolinium or not.

DSA and MR subtraction are slightly different in implementation, yet both deserve to be featured in RadiAnt.

probably MR subtraction will be easier to implement than DSA subtraction.

do you think that the fusion feature could in some way modified to obtain a subtraction feature or this must be created by scratch.

Tommy, both MR and DSA subtraction modes are not very hard to implement (they do require some time, though). The fusion feature implementation is quite different, so the subtraction has to be created almost from scratch.

No, there's no subtraction available yet in RadiAnt.

Kind regards,

Is DSA still in development? I am retired now but I used it extensively in congenital heart disease to the extent that I used to turn off the automatic dose control in order to optimize it. It is still very useful if the AGC is on and even if respiration is not suspended.

Yes, there are still plans to develop the DSA feature. There is no time frame set, however. Surely not before 2017.

I would like to again add to the conversation that this feature (XA subtraction mostly for me) woulde be a real killer feature for Radiant. It's the only thing stopping me from giving up Osirix/Horos for Radiant. Please add!

Still no time frame for this feature. We would like to see it happen this year, anyway...
