I have installed slicer 4.6.2 and now experience very slow loading of DICOM files (minutes rather than a few seconds as with version 4.3). is there a way to fix this?

Hi Steven,

Please, download the latest nightly build available at [http://download.slicer.org](http://download.slicer.org)

We recently improved the loading of DICOM (5 to 10 times faster). See [Slicer DICOM import performance](https://discourse.slicer.org/t/slicer-dicom-import-performance/922)

If you still experience slow loading, let us know and we will have an other look.
