PURPOSE/AIM

1) Review the spectrum of early and delayed normal cross sectional imaging findings after TACE of hepatic tumors 2) Discuss imaging in the immediate postprocedural time period, including pertinent findings of successful embolization, evaluation of tumoral necrosis, and predictors of recurrence. 3) Illustrate complications after TACE and follow up imaging preceding recurrences. 4) Demonstrate evolution of treated lesions and postprocedural liver changes over time.

CONTENT ORGANIZATION

1) Role of TACE in the treatment of primary and secondary liver tumors 2) Pre-TACE evaluation 3) Expected CT and MRI findings following TACE -Evaluation of tumoral necrosis and grading lipiodol staining -Normal post-treatment changes such as perfusion abnormality -Indicators for long term success 4) Complications -Immediate postprocedure complications -Delayed complications, including recurrence

SUMMARY

Major teaching points: 1) Postprocedure CT and MR should report absence of intratumor enhancement and findings supporting the presence of tumoral necrosis. 2) Nonenhancing lesions after TACE without findings supporting tumoral necrosis warrant close attention on follow-up imaging. 3) Hepatic complications of TACE include nontarget embolization, hepatic abscess, biloma, liver infarct and hepatic failure.
