Digital breast tomosynthesis offers many clinical advantages, but it also creates enormous amounts of data. The size of an examination is significantly larger than with 2D mammography. This means that introducing tomo reading is about more than reading times, detection rates, and recall rates. It’s also about having the right IT infrastructure.
Is your IT ready for digital breast tomosynthesis?
So before introducing digital breast tomosynthesis, clinical facilities should take a closer look at their IT network first. For an efficient tomo workflow, a powerful IT is required with fast network protocols that quickly transports the large amounts of data from the scanner to the workstation as well as a special PACS solution that offers enough storage space.
Overview of storage space needed
The image below clearly depicts how much more storage space is needed for 3D tomosynthesis compared to 2D mammography. For the calculation example we estimated:
- 20 MB for a 1-view mammogram
- 10 MB for a single tomo slice and 50 slices for one view
This means for a 4-view study:
The data of the tomo studies can of course be compressed, for example with JPEG Lossless. This can result in about half the storage need.
Servers are not the only place to store data
Storing the images on site is not the only solution available. Cloud-based storage is another option to handle the massive increase in imaging data. But to efficiently send tomo studies into the cloud – or to peers for teleradiology – a high internet bandwidth speed is essential to upload and download the large data volume in a good speed.
