The correct diagnosis rate of T staging results of MSCT, DCEUS, and combined diagnosis. Note: (1) comparison of correct diagnosis rate of MSCT and DCEUS in different T staging: T1 staging, χ² = 13.015, ; T2 staging, χ² = 6.132, ; T3 staging, χ² = 10.451, ; T4 staging, χ² = 5.177, ; summation, χ² = 7.152, . (2) Comparison of correct diagnosis rate of MSCT and the D&M method in different T staging: T1 staging, χ² = 16.541, ; T2 staging, χ² = 9.648, ; T3 staging, χ² = 15.224, ; T4 staging, χ² = 8.674, ; summation, χ² = 11.192, ; (3) Comparison of correct diagnosis rate of DCEUS and D&M method in different T staging: T1 staging, χ² = 4.482, ; T2 staging, χ² = 2.697, ; T3 staging, χ² = 4.847, ; T4 staging, χ² = 4.052, ; summation, χ² = 2.387, .
