Multiparametric MRI (mpMRI) is currently the test of choice for imaging sites of prostate cancer located within the pelvis. However, molecular imaging with PET radiotracers that bind to prostate-specific membrane antigen is increasingly being used for this purpose and may compliment mpMRI findings. We present a case of a 59-year-old man with elevated postprostatectomy serum prostate-specific antigen level who was found on both mpMRI and prostate-specific membrane antigen-targeted PET to harbor residual prostate cancer in the corpus spongiosum along the proximal urethra.
多参数 MRI(mpMRI)目前是用于成像骨盆内前列腺癌部位的首选检查方法。然而,与前列腺特异性膜抗原结合的 PET 放射性示踪剂的分子成像也越来越多地用于此目的,并且可以补充 mpMRI 的发现。我们报告了一例 59 岁男性,前列腺切除术后血清前列腺特异性抗原水平升高,mpMRI 和前列腺特异性膜抗原靶向 PET 均显示在近端尿道的海绵体部有残留的前列腺癌。
