Check out Unicornscan.  And while your at it look at Scanrand too.  
Unicornscan attempts to get around the issue with UDP scanning by 
pre-defining certain UDP payloads to send for each known service which 
can produce more accurate results.  It will help with 20 or so of the ports.

It's detailed in the first Q&A:
