Viewer. (a) T1-weighted MR image demonstrates an enlarged left common iliac lymph node (arrow) that is isointense relative to blood vessels and muscles. Staging is based on the results of a physical exam, imaging scans, and biopsies. Figure 8b. 2, Reviews in Gynaecological Practice, Vol. Axial T2-weighted MR image shows a slightly hyperintense lymph node (arrow) that is well differentiated from muscles and blood vessels. A rising prevalence of unsuspected metastatic lymph nodes is found with each successive stage, ranging from 5% positive pelvic nodes in stage IA2 to 55% in stage IV (,2). Cervical carcinoma.

Viewer. However, there are significant inaccuracies in the FIGO staging system, and magnetic resonance (MR) imaging, although not included in that system, is now widely accepted as optimal for evaluation of important prognostic factors such as lesion volume and metastatic lymph node involvement that will help determine the treatment strategy. When treatment planning changes due to a suspicious increase in the volume of a lymph node, biopsy should be performed because the node may be falsely positive due to inflammation. 19, No. Figure 18.

The tumor should be measured in three orthogonal planes. Figure 4. T2-weighted imaging is preferred for evaluation of the lymph nodes, which are more clearly distinguished from the hypointense muscles and blood vessels with this sequence (,,,Fig 2). Sagittal T2-weighted MR image demonstrates hyperintense bullous thickening of the bladder wall (arrow). Ring flow artifact. Hyperintense thickening of the bladder mucosa at T2-weighted imaging indicates edema and is not a direct sign of invasion. Brachytherapy and external beam therapy are optimized with MR imaging evaluation of the shape and direction of lesion growth.

The best treatment modality for each patient (ie, surgery or radiation therapy) can be determined more accurately with MR imaging, which has been shown to influence treatment planning in one-half of patients (,2). Therefore, detection of nodal disease is crucial for treatment planning.
