From: A retrospective analysis of the prognosis of prostate cancer patients with lymph node involvement on MR lymphography: who might be cured

Figure 1

Example of a negative (A) and a positive (B) MRL. Upper panel: T1 image, which provides good visualization of non-enlarged lymph nodes (arrows). Lower panel: T2* image. The positive lymph node ( B ) has a high signal intensity, because accumulation of the iron particles has been blocked. This in contrast to the low signal intensity of the negative lymph node ( A ). Modified from: Hanneke J.M. Meijer et al.; Magnetic resonance lymphography findings in patients with a biochemical recurrence after prostatectomy and the relation with the Stephenson nomogram. Int. J. Radiat. Oncol. Biol. Phys. 2012; 84(5): 1186–1191.
