Optimizing detectability of renal pathology with MDCT: protocols, pearls, and pitfalls

AJR Am J Roentgenol. 2010 Apr;194(4):1001-12. doi: 10.2214/AJR.09.3049.


Objective: The purpose of this article is to review MDCT acquisition protocol parameters and interpretative practices for evaluating genitourinary lesions other than classic renal cell carcinoma, to optimize lesion detectability and accurately characterize pathologic abnormalities.

Conclusion: With the goal of refining interpretative performance, this pictorial essay shows the patterns of conspicuity unique to each genitourinary pathologic abnormality, presents experience-based recommendations to improve detection and characterization using multiphasic MDCT, and describes pitfalls to be avoided.
