| No APHE | 40.4 (19/47) | 95.7 (89/93) | 77.1 (108/140) | 82.6 (19/23) | 76.1 (89/117) |
| Vascular invasion | 87.2 (41/47) | 55.9 (52/93) | 66.4 (93/140) | 50.0 (41/82) | 89.7 (52/58) |
| Any two or more | 59.6 (28/47) | 95.7 (89/93) | 83.6 (117/140) | 87.5 (28/32) | 82.4 (89/108) |
| Any three | 23.4 (11/47) | 100.0 (93/93) | 74.3 (104/140) | 100.0 (11/11) | 72.1 (93/129) |
Data are presented as percentages. Data in parentheses are the number of subjects used to calculate the percentage. PPV, positive predictive value; NPV, negative predictive value; APHE, arterial phase hyperenhancement.
