| Abstract | ||
| Background: diagnosis of liver metastases is of essential importance in the staging of patients with a known primary tumor. Aim of the work: The study aimed to evaluate role of DWI in diagnosis of liver metastasis. Patients and methods: twenty patients were included in this study. The cases were evaluated over 6 months at Ain Shams University Hospital with a 1.5 Tesla Phillips (MR System Achieva) whole body imager. Results: in the sample of the study which was composed of 20 patients there were two patients who presented with negative lesion in DW MRI with sensitivity 100%, specificity 90% and accuracy 95%. Conclusion: DWI alone performs equally well as Gd-MRI in the diagnosis of liver metastases. In cases where gadolinium injection is not allowed, dynamic contrast-enhanced imaging can be replaced by a protocol based on unenhanced T1- and T2-weighted imaging combined with DWI. Recommendations: Further studies on larger scale of patients are needed to confirm the results of the study. | ||
