Conversion from Point to Raster

I am new to ArcMap and I would really appreciate some help. I want to create a new raster using a value in a column of a point shapefile.
I had a 8bands raster image and used the 'raster to point' tool to extract all points from the raster, in this way I obtained a point shapefile with a number of points equal to the number of pixels in the raster and with the points placed in the center of each pixel.
I extracted the values from the 8band raster and run (with other software) some analysis on each point (= each pixel) and joined it to the point table in a new column.
Now I want to create a raster with the same resolution of the original 8band raster but using as value the new column in the table. How can I do that?

I tried running 'Point to raster' but it's not doing what I am looking for.
Thank you for your help!
