title: Comparison of ultrasound and CT images of liver metastases.
abstract: The US and CT images of liver metastases in 42 patients were systematically compared. Based on the US image the lesions were classified as non-echogenic, slightly echogenic, and markedly echogenic lesions, target lesions and lesions with diffuse alteration of structure. There was often discrepancy between the appearance of the US and CT images. The discrepancy was increased after contrast enhancement in non-echogenic and in slightly echogenic metastases and in metastases with diffuse alteration of echo structure and diminished in target lesions. The possible reasons for these differences are discussed.
