Magnetic resonance lymphography.
OBJECTIVE
The current methods of noninvasively staging retroperitoneal lymph nodes are suboptimal. Magnetic resonance lymphography is a new technique that might offer an important new tool in this area. Although it is still in development, more and more studies show that it is highly effective in detecting nodal metastases of various tumors.


RESULTS
Magnetic resonance lymphography yields higher sensitivity than the reference methods for detecting malignant nodes in patients with prostate, bladder, or testicular cancer.


CONCLUSIONS
In certain groups of patients with urologic cancer, magnetic resonance lymphography may obviate the need for lymphadenectomy and replace the currently used computed tomography scanning or unenhanced magnetic resonance imaging that are based on insensitive size criteria.
