This frontal x-ray of the urinary bladder (pink) from an intravenous pyelogram (IVP) was obtained 20 minutes after the intravenous injection of iodinated contrast. It shows a beautifully normal appearance of the bladder. This test is being performed less frequently because of the widespread use of the spiral CT technique.
