Twenty-six patients with prostate cancer status post-radical prostatectomy who were candidates for salvage radiation therapy (SRT) underwent lymphotropic nanoparticle enhanced MRI (LNMRI) using superparamagnetic nanoparticle ferumoxtran-10. LNMRI was well tolerated, with only two adverse events, both Grade 2. Six (23%) of the 26 patients, previously believed to be node negative, tested lymph node positive by LNMRI. A total of nine positive lymph nodes were identified in these six patients, none of which were enlarged based on size criteria.
