[The MRI of cervical lymph node metastasis with malignant tumor of the head and neck].
A prospective diagnostic study on cervical lymph node metastasis from malignant tumor of the head and neck using MRI was performed for 62 cases in order to assess the potential or limitation of MRI for demontrating the pathological cervical lymph node. The double blind method was used in the study. The result reveals MRI has obvious higher sensitivity (85.7%), higher specificity (94.8%) and higher accuracy (89.6%) than palpation. Besides changes in size and shape of the lymph nodes, the intensity of MRI inside lymph nodes was altered showing, mixed hypo-iso-intensity in T1WI and hyper intensity in T2WI. Thus, MRI will probably play an important role as a staging modality in the detection of malignant lymph nodes metastasis.
