Hello all,

I’m new to using Slicer and have run into a couple issues regarding displaying MRI data. So I have multiple datasets I am working with, some of which are anatomical, taking cross sections over different sagittal planes. These frames display very readily in 3D Slicer, and I have had not issue with them. My issue arises when I attempt to display MRI data in the same plane, that has been taken over time. I tend to get a rhombus-shaped cross section that slides from left to right for a single time-point. See the attachment for an example. How can I have Slicer display the entire 300-frame set?  
 ![cross section MRI](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/2/8/288ef84d3a41ffef0d1ed090cb2bbe8265ebe2de.png)

ALSO, in the past I have used ImageJ for these analyses, but learned about Slicer and was hoping it had some capabilities I need for research. The first is, I want to determine changes in a very specific area of an MRI over time. Specifically, I want to draw a line through an organ and have it take the same line from all 300 frames in a data set and display them side-by-side. Is anything like that possible?

Thank you in advance!

Best,  
D

In Slicer-4.11 and earlier, slice views are aligned to anatomical axes by default and you need to click [“Rotate to volume plane” button](https://slicer.readthedocs.io/en/latest/user_guide/user_interface.html#slice-view) to make it snap to the image slice’s orientation. In Slicer-4.13 (recent Slicer Preview Releases), when you click on the eye icon of a volume in Data module, the slice view is rotated to the image plane by default. You can also [drag-and-drop a volume into a slice view](https://slicer.readthedocs.io/en/latest/user_guide/user_interface.html#selecting-displayed-data) to make that volume show up in that view, with the slice view orientation aligned with the image axis.

Thank you, Dr. Lasso, much appreciated!
