[ RadSafe ] Th-201 and portal monitors

[Borisky, Michael (Civ, ARL/ADLO)]

On a somewhat related subject, there is apparently a CAT scan procedure
that is sometimes used in conjunction with the standard cardiac stress
test or even in place of it.  Apparently they can scan the coronary
arteries with CAT and get an idea of the extent of blockage. 

Can someone tell me how the dose from a standard stress test compares to
the dose from the alternative CAT scan procedure.

Thanks

Michael,
Good proof reading. Obviously, Tl-201 is the isotope involved, since it 
would seem that Th-201 might be a bit too unstable to manufacture and 
distribute :-)
