Yep you can use either the shout or the spell. There is a spell tome for it, as well as a scroll and the shout for those who dont want to use alteration magic. http://www.uesp.net/wiki/Skyrim:Detect_Life
Apparently the spell uses different colors to identify enemies (red) as well as friends (blue). Apparently the shout does not do this and will show any life in red.
