can anyone help me please
You can use Segment Editor to segment the aneurysm sack and compute volume using Segment statistics module.
You can measure height and width by using annotation ruler (available in the toolbar). To find a good slice to measure in, you can show slice intersections (using dropdown menu of crosshair button in the toolbar) and rotate it using Reformat module or (if you use a recent Slicer Preview Release) then you may also rotate it using Ctrl+Alt+Left-click-and-drag.
