Noninvasive assessment of tumor microenvironment using dynamic contrast-enhanced magnetic resonance imaging and 18F- fluoromisonidazole positron emission tomography imaging in neck nodal metastases
Carcinoma, Squamous Cell
Head and Neck Neoplasms
Magnetic Resonance Imaging
This initial evaluation of the preliminary results support the hypothesis that in metastatic neck lymph nodes, hypoxic nodes are poorly perfused (i.e., have significantly lower K(trans) and k(ep) values) compared with nonhypoxic nodes.
