How can I correct the noise in my 3d model?

Hello 3Dslicer support team
I hope this massage finds you well.

As you can see my 3D model and coronal and sagittal views in 3D slicer has noise like these. but there is high quality images in axial view. I tried to rescale or reslice this Dicom file but I couldn’t get the result. Also I couldn’t get the corrected results when I was trying to segment model just using axial view.
So I will appreciate if you help me to get a good 3D model
