Objectives:

Evaluate the diagnostic sensitivity of the triphasic helicoidal tomography, to differentiate benign hepatic tumoral lesions from the malignant.

Methods:

The study was performed in the tomography department of Centro de Diagnóstico Tecniscan de Guatemala, from January to July, 2012.  Triphasic helicoidal tomographies of 67 patients referred for hepatic tumoral lesions during the 6 month period were evaluated and related to the histopathologic diagnosis, determining the diagnostic sensitivity of the triphasic helicoidal tomography.

Results:

In the 67 patients evaluated, 88 lesions were characterized with help from the enhancement patterns in the different vascular phases; 39 being malignant lesions (44.3%) and 49 benign lesions (55.7%).    The results concurred 100% with the histopathology results.

Conclusion:

The triphasic helicoidal tomography is a good, non-invasive tool, to characterize and differentiate the benign hepatic lesions from the malignant.
