ABSTRACT

PURPOSE:

The purpose of our study was to characterize the enhancing patterns of hepatic metastasis from gastric adenocarinoma using multi-phase incremental bolus dynamic CT with obtained both in early and late phase contrast scan and to evaluate the its advantages. METHODS AND MATERIALS Of 33 cases of multi-phase incremental bolus dynamic CT with proved hepatic~metastasis from gastric adenocarinoma, we classified dynamic enhancement patterns as three types according to early phase contrast enhancement, and then analized the late phase contrast enhancement, more metastasis detection, segmental abnormal arterial perfusions and correlation between pathologic type.

RESULTS:

Type I (totally hypodense lesion) was in 18 patients(55%), type II (peripheral high density area) was seen in 13 patients (39%), and type III (near totally hyperdense lesion) was seen in two patients(6%). But in late phase, masses showed totally hypodense area in 26 patients(79%), central high with peripheral low density area(PLDA) in six patients(18%) and totally isodense in one patient(3%). More metastatic masses were detected with early phase in 11 patients(33%) as compared with late phase contrast. Segmental arterial hyperperfusion around the lesions, which could represent intrahepatic portal branch invasion, was seen in 10 patients(30%). There was no correlation between pathologic type and enhancement pattern of lesions.

CONCLUSION:

Multi-phase incremental bolus dynamic CT could represent variable hemodynamic changes of hepatic metastatic masses and was useful to evaluate the qualitative and quantitative analysis of hepatic metastases.
