Good exam. : CTA very accurate. CTA must be tailored to your problem to be the most accurate. Sometimes Doppler ultrasound, magnetic resonance angiography/ MRA, or conventional angiography are required instead. See radiologyinfo.org for details about these studies.

Depends.: For kidney stones we use no contrast, but we don't get as good a look at the solid organs. Contrast is usually helpful, but not always necessary.
