Popis: Purpose : Wide angle tomography is used regularly during excretion urography to overcome the problem of bowel shadows obscuring the kidneys. Because Methods : A specially constructed renal phantom was used to establish radiation dose levels for tomography and zonography. Subjective analyses on su Results : Statistical analysis demonstrated that fewer exposuresper intravenous urography examination were necessary for zonography (1.6) compared w Conclusions : This investigation suggests zonography should replace tomography for routine excretion urography with potential benefits for patient d
