Imaging of the urinary tract: the role of CT and MRI.

Hiorns MP - Pediatr. Nephrol. (2010)

Bottom Line: Computed tomography (CT) and magnetic resonance imaging (MRI) are increasingly valuable tools for assessing the urinary tract in adults and children.The use of CT and MRI should therefore be tailored to the patient and the clinical question.For the scope of this article, the advantages and disadvantages of these techniques in children will be considered; different considerations will apply in adult practice.

ABSTRACT
Computed tomography (CT) and magnetic resonance imaging (MRI) are increasingly valuable tools for assessing the urinary tract in adults and children. However, their imaging capabilities, while overlapping in some respects, should be considered as complementary, as each technique offers specific advantages and disadvantages both in actual inherent qualities of the technique and in specific patients and with a specific diagnostic question. The use of CT and MRI should therefore be tailored to the patient and the clinical question. For the scope of this article, the advantages and disadvantages of these techniques in children will be considered; different considerations will apply in adult practice.

Mentions: CT arteriography (CTA) is sometimes performed in instances of known horseshoe kidney when surgery is being planned. This is to optimally delineate the multiple vessels that often supply these kidneys before surgery is undertaken. Pelviureteric junction obstruction can usually be diagnosed adequately on US, but a crossing vessel may be demonstrated by MRI (Fig. 3) [14], which cannot be visualized by US; in very gross hydronephrosis, MRI may give a better demonstration of the anatomy (Fig. 4).Fig. 3
