 Siemens MR is named by Series, Generation, Major Version and Minor Version. Prior to the Siemens Vida, all contemporary Siemens MRI systems (Trio, Prisma, Skyra, etc) were part of the V series. So a Trio might be on VB17, and a Prisma on VE11 (series 'V', generation 'E', major version '1', minor version '1'). The 3T Vida and 1.5T Sola introduce the X-series (XA10, XA11, XA20). Since the V-series was dominant for so long, most users simply omit the series, e.g. referring to a system as `B19`. However, Siemens has recently introduced a new X-series.
 
-The DICOM images exported by the X-series is radically different than the V-series. The images lack the proprietary CSA header with its rich meta data.  
+The DICOM images exported by the X-series is [radically different](https://wikis.utexas.edu/display/IRC/New+Enhanced+DICOM+format) than the V-series. The images lack the proprietary CSA header with its rich meta data.
 
 X-series users are strongly encouraged to export data using the "Enhanced" format and to not use any of the "Anonymize" features on the console. The consequences of these options is discussed in detail in [issue 236](https://github.com/rordenlab/dcm2niix/issues/236). Siemens notes `We highly recommend that the Enhanced DICOM format be used. This is because this format retains far more information in the header`. Failure to export data in this format has led to catastrophic data loss for numerous users (for publicly reported details see issues [203](https://github.com/rordenlab/dcm2niix/issues/203), [236](https://github.com/rordenlab/dcm2niix/issues/236), [240](https://github.com/rordenlab/dcm2niix/issues/240), [274](https://github.com/rordenlab/dcm2niix/issues/274), [303](https://github.com/rordenlab/dcm2niix/issues/303), [370](https://github.com/rordenlab/dcm2niix/issues/370), [394](https://github.com/rordenlab/dcm2niix/issues/394)). This reflects limitations of the DICOM data, not dcm2niix.
