Color Doppler Ultrasound - any successes, false negatives ?

There is a lot of talk on these groups about Color Doppler UltraSound,
and CDUS-guided biopsy. I am wondering, has anybody actually beed
diagnosed with a PCa using CDUS when other diagnostics before it
failed ? And the other way around - has anybody had a negative CDUS
(or CDUS-guided biopsy) just to have a PCa diagnosed later ?
