Frequently, the SLN technique detected bilateral LN (56, 61, 62). Common imaging tests used to check lymph nodes include CT scans, MRI scans, X-rays, and ultrasound. doi: 10.1016/j.eururo.2012.08.003, 17. Amino acid transport and metabolism is upregulated in malignant cells, including PCa cells. Updated nomogram predicting lymph node invasion in patients with prostate cancer undergoing extended pelvic lymph node dissection: the essential importance of percentage of positive cores. In contrast to other imaging modalities, such as CT, which primarily rely on size criteria to diagnose malignant invasion, ultrasonography also permits analysis of various echo features of the visualized lymph nodes to predict malignant invasion. Jeschke et al. The ability of MR to demonstrate normal-size (less than 10 mm) lymph nodes in the chest was comparable to that of CT. 2004;45 (9): 1509-18. (2014) 65:1162–8. As such, this PSMA-labeled radiotracer could facilitate lymphadenectomy in patients with very high-risk and oligometastatic PCa, in which metastatic LNs have initially been detected by PSMA imaging. The literature is limited on the diagnostic accuracy of FDG PET in LN staging for PCa, but it still probably have a place in the staging for advanced PCa with high Gleason score or undifferentiated PCa.

Second, the false negative rate may be due to an obliteration or obstruction of lymphovascular vessels and nodes by metastatic cells. Lymph nodes can often be adequately localized with planar imaging alone (62,63). Quantitative [Fe]MRI of PSMA-targeted SPIONs specifically discriminates among prostate tumor cell types based on their PSMA expression levels. So if you have a large, swollen area but you’re not feeling sick and you didn’t recently have a cold, flu, upper respiratory infection or skin infection, you’ll need further tests, like blood work, imaging … 18F-Fluoroethylcholine PET/CT identifies lymph node metastasis in patients with prostate-specific antigen failure after radical prostatectomy but underestimates its extent.
