Which of the following is NOT an indication of static cystography?
evaluating a probable bladder rupture
evaluating a probable colovesical or vesicovaginal fistulae
evaluating a probable intravesical pathology

Correct Answer :
B. evaluating a probable colovesical or vesicovaginal fistulae
evaluating a probable vesicovaginal fistula is better carried out by MRI.

What is false on comparing Tc-99m DTPA to Tc-99m MAG3?
DTPA provides better quality images with renal insufficiency

DTPA provides an excellent measurement of GFR
in pediatrics, MAG3 provides better quality images than DTPA
