Can an LCD TV be used as a PC monitor and vise versa?
And why is a 22" TV almost double the price of a 22" monitor?
Yes, they can be used vice versa:

No they can not be used vice versa
you can use LCD TV as PC monitor. but you can't use LCD monitor as TV, as it will not contain TV tuner, and more over the resolution on offer with the monitor makes it unsuitable for long distance viewing i.e., normal TV viewing is not that great on monitors. now a days some monitors are coming with inbuilt TV tuners.

and for the difference of price the TV contains Tuner and speakers and it is optimized for TV viewing and monitors are not.
With a set-top box, LCD monitor can be used as a TV. Set-top box contains tuner. Check that Instructibles link.
1. LCD tv comes with internal speakers and tuner whereas most of the monitirs dont have these
2. LCD monitor has only one input > VGA whereas LCD tv has many inputs > VGA, RF, AV, component etc
So lcd tv is costly
