Discrimination of metastatic cervical lymph nodes with diffusion-weighted MR imaging in patients with head and neck cancer.
BACKGROUND AND PURPOSE Metastasis to the regional cervical lymph nodes may be associated with alterations in water diffusivity and microcirculation of the node. We tested whether diffusion-weighted MR imaging could discriminate metastatic nodes. METHODS Diffusion-weighted echo-planar and T1- and T2-weighted MR imaging sequences were performed on histologically proved metastatic cervical lymph...
متن کاملPower Doppler sonography of cervical lymph nodes in patients with head and neck cancer.
PURPOSE The purpose of this preliminary study was to evaluate the usefulness of power Doppler sonography in differentiating metastatic from nonmetastatic cervical lymph nodes in patients with cancer. METHODS Histologically proved metastatic (n = 71) and nonmetastatic (n = 220) lymph nodes were examined with power Doppler sonography in 77 patients with head and neck cancer. Power Doppler sonog...
متن کاملsonographic evaluation of cervical lymphadenopathy; comparison of metastatic and reactive lymph nodes in patients with head and neck squamous cell carcinoma using gray scale and doppler techniques
conclusion gray scale sonography in combination with doppler sonography could be a trustworthy technique in differentiating metastatic lymph nodes from reactive ones. although, circulation pattern had a higher diagnostic accuracy in the present study, combination of sonographic characteristics could be more beneficial in differentiating metastatic cervical nodes from reactive ones. results the ...
متن کاملreview the appropriate approach for evaluation of metastatic cervical lymph nodes on cross-sectional neck imaging
the imaging assessment of nodal disease can be challenging for the radiologist because there are multiple sites to review and differing opinions about criteria for abnormal nodes. the ability to accurately detect nodal metastases is improved with knowledge of the criteria for abnormal nodes, the nodal drainage patterns, and common imaging pitfalls. in this article, we introduce these basic conc...
متن کاملImmunohistochemical detection of micrometastases in 580 cervical lymph nodes from patients with head and neck malignancies
Aims: Our study was designed to find out the incidence of micrometastases in 580 cervical lymph nodes using serial sectioning and by using immunohistochemical stains CK(cytokeratin) and EMA(epithelial membrane antigen). Settings and Design: study was conducted on 30 patients who were diagnosed with head and neck carcinomas and subsequently underwent neck dissections. Patients with head and neck...
