| Abstract: | Purpose:To study the mechanism and clinical diagnostic value of low signal on T 2WI.Materials and methods: 122cases were examined by philips 1.0T MR scanner. TR1800-2000ms/TE80-150ms.Results: Acute hemorrhage 30 cases.Chronic hemorrhage 60 cases. Melanoma 2 cases.Liver cirrhosis nodes.Retinoblastoma 5 cases.Others 15 cases. Conclusion: Low signals on T 2WI is important for diagnosis and differential diagnosis of the disease. |
