  • Title: [The differential diagnosis of liver metastasis and regional fatty liver: a comparison of CT and MRT].
    Author: Schörner W, Neumann K, Langer M, Heim T, Keck H, Felix R.
    Journal: Rofo; 1991 Jun; 154(6):628-33. PubMed ID: 1648766.
    Abstract:
    Differentiation between liver metastases and local fat deposition may be difficult when using CT; the value of MRI was therefore investigated in 18 patients with metastases and ten patients with fat deposits. CT shows both lesions as similar hypodense areas. MRI, however, produces different appearances: T1- and 2-weighted images show marked differences in the signal arising from metastases, whereas local fat collections in both sequences differ little in their signal from normal liver. Quantitative MRI signal intensity of the two types of lesion were also different. Where the differentiation by CT may be difficult, it may be made with certainty by means of MRI.
