BACKGROUND AND OBJECTIVES: The ideal method for screening investigations is one
which is as free as possible from side effects, is easily learnt, and can
therefore be broadly used to detect abdominal aortic aneurysms (AAA) with a high
degree of certainty. Although ultrasonography fulfils these criteria, the
measurement method is not standardized. Different measurement methods are used in
ultrasonography as well as in computed tomography (CT) studies and the
measurement method is actually described sufficiently in only 57?% of cases.
METHODS: This article provides a critical review of the current literature on
measurement methods and the validity of ultrasonography for the determination of
aortic diameter, particularly in AAA, and presents the measurement principles for
making measurements as precisely as possible. RESULTS AND CONCLUSION: The most
precise determination of aortic diameter is carried out by electrocardiogram
(ECG) gating according to the leading-edge method with orthogonal slicing. Within
the framework of screening investigations, sufficient measurement precision can
be achieved by adherence to orthogonal slicing. Using these standardized
measurement methods, ultrasonography shows valid and reproducible results even
compared with CT and is the method of choice in screening investigations for AAA.
