Table 5 Comparison of plain MR with coronal LAVA imaging versus final diagnosis in tumor invasion

From: Comparison of preoperative evaluation of malignant low-level biliary obstruction using plain magnetic resonance and coronal liver acquisition with volume acceleration technique alone and in combination

Adjacent organ infiltration 91 (30/33) 89 (17/19) 93 (13/14) 94 (17/18) 87 (13/15)
Vascular infiltration 88 (29/33) 67 (6/9) 96 (23/24) 86 (6/7) 88 (23/26)
Lymph node metastases 91 (30/33) 92 (12/13) 90 (18/20) 86 (12/14) 95 (18/19)
Liver metastases 97 (32/33) 100 (6/6) 96 (26/27) 86 (6/7) 100 (26/26)
