Independent measurements were taken by 19 observers; 4 consultant vascular radiologists and 15 radiographers (mean post qualiﬁcation experience 10.4 years, range 1e20 years). Analysis of intra-observer variability was undertaken to determine the difference in AAA measurements between individual observers. Intra-observer variability was higher for radiologists 2.1 3.5 mm compared with 0.18 2.6 mm for radiographers. Although differences
existed between the two observer types and was maintained when categorising the paired differences (5 mm) this did not reach statistical signiﬁcance. Full results of the intra-observer analysis for each observer type are shown in Table 1 and Figs. 1 and 2.
Inter-observer variability within each observer group was calculated in order to allow the comparison of measurements made by observers of the same discipline (Table 2, Figs. 3 and 4). Mean paired differences were equivocal for both disciplines (radiologists 0.09 3.1 mm; radiographers 0.1 5.0 mm) but radiologists had increased consistency when paired differences were categorised. For radiologists 67% of paired measurements were within 2 mm and 91% were within 5 mm compared to 42% and 80% for radiographers, these results were not statistically signiﬁcant.
Direct comparisons of the consultant radiologists’ measurements with radiographers are displayed in Table 3 and Fig. 5. Inter-observer variability was good with 43% of paired measurements within 2 mm and 78% within 5 mm. Finally, radiologists and radiographers were compared on the slice selection chosen for each measurement, results
demonstrate that repeat slice selection was within 1 CT slice or less for 91% of radiologists and 88% of radiographer measurements (NS, PZ0.228; Table 4).

獨立測量採取了19觀察員; 4顧問血管放射科醫師和放射技師 15（平均10.4年工作經驗後，範圍 1e20年）。分析內變異進行了觀測，以確定測量值之間的差異在AAA個別觀察員。內部觀察員變異較高的放射科醫師 2.1 3.5毫米，而0.18 2.6公厘為技師。雖然分歧
之間存在著兩個觀察員類型，並分類配對時，保持差異（5毫米），這並沒有達到統計意義。全部結果的內部分析每一個觀察員，觀察員類型見表 1和圖。 1和2。
間內的每一個觀察員，觀察員可變性組計算，以便進行比較測量由同一學科觀察員（表2，圖。3和4）。平均配對差異模棱兩可兩個學科（放射0.09 3.1毫米;技師 0.1 5.0毫米），但增加了一致性放射配對差異歸類。對於放射科67％的配對測量均在2毫米和91％相比，均在5毫米至42％和80％的技師，這些結果並不顯著。
