Pediatrician Int 41:538-541. doi.org/10.1046/j.1442-200x.1999.01124.x US AAA over 5 years old were analyzed retrospectively. Landlocked patients had aneurysms of ≥5 cm on US followed by a CT scan within 2 months (n = 123). Based on maximum U.S. diameters, 44 patients had aneurysms between 5 and 5.4 cm (group I) and 79 patients ≥5.5 cm (group II). Results were reported cross-sectionally. Correlation and match limits were calculated. Two radiologists again measured 44 pairs of CT/US scans and Inter-Observer biases to determine the differences between the calculated imaging modalities.
