Abstract
AIM: To compare unidimensional, bidimensional computed tomography (CT), and volumetric techniques for evaluation of therapeutic response in patients with liver metastases from breast and colon carcinoma.
METHODS: Helical CT performed in 22 patients with liver metastases before and 3 mo after interventional treatment. All lesions were measured on transverse CT scans with electronic calipers according to both unidimensional and bidimensional criteria. Volumetric measurements were made by tracing individual lesions, and measurements of individual lesion were summed to obtain patient response, which were categorized as complete response, partial response, disease progression, and disease stabling (size response other than that of complete response, partial response, or disease progression) ......
