Three experienced uroradiological readers were blinded from the previous CT reports. Weighted \u03ba was calculated to assess agreement, defined as: fair, 0.21\u20130.40; moderate, 0.41\u20130.60; good, 0.61\u20130.80; and very good, 0.81\u20131.00.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>For readers the distribution of correctly classified lesions were as follows: BI, 95\u2013100%; BII, 59\u201393%; BIIF, 54\u201392%; BIII, 58\u201395%; and B IV, 77\u2013100% for the first review.
