Extravasated contrast volumetric assessment on computed tomography angiography in gastrointestinal bleeding: A useful predictor of positive angiographic findings

Figure 2 Bland-Altman plot for inter-reader agreement of volumetric analyses. A: Arterial phase volumes: 2/35 (5.71%) outside "agreement" limits. Mean difference, -0.05; upper agreement limit, 0.98; lower agreement limit, -1.98; B: Venous phase volumes: 1/35 (2.86%) outside the agreement limits. Mean difference, -0.56; upper agreement limit, 5.03; lower agreement limit, -6.15.
