本篇EAU报道纳入了3个欧洲三级中心的数据,结果显示,在首次生化复发患者中,PSMA PET阳性与阴性患者的3年无生化复发生存率和无影像学进展生存率类似;在既往挽救性治疗后生化复发患者中,PSMA PET阳性患者的3年无影像学进展生存率和无CRPC生存率显著低...

UPDATE: Now Performing PSMA PET SCANS - Schedule with us today, The #1 HIGHEST Rated PET scan service provider nationwide.
The PSMA PET scan is an emerging imaging modality with improved sensitivity and specificity over conventional imaging for prostate cancer staging. It uses PET in conjunction with a tracer that is highly effective in detecting prostate cancer throughout the body so the precise location of the...
英国药品和保健产品管理局已批准前列腺癌PET显像剂TLX591-CDx (Illuccix)的上市许可申请,用于制备镓-68 gozetotide注射液。该试剂盒现已被批准用于使用PET对成年前列腺癌患者的PSMA阳性病变进行检测和定位,将在英国和爱尔兰上市。 “scan在过去的12个月里,随着需求的增加,英国和欧洲的PET供应短缺已经升级,这导致了急需...
图1. 从头骨到大腿中部获取的全身[68Ga]Ga-PSMA PET扫描示例。左图(A)展示了未进行任何分割的冠状视图,中间图(B)展示了手动分割,右图(C)展示了自动分割。结果显示,在体素级分割中,CNN的性能良好,Dice分数为85%,阳性预测值(PPV)为85%。 Fig. 2 An example of a whole body [68Ga]Ga-PSMA PET scan ac...
As PSMA-PET/CT is routinely used for prostate cancer diagnosis due to its improved accuracy over traditional imaging techniques, an increasing number of non-prostate lesions are also being identified. Here, we report a patient with prostate adenocarcinoma, who was diagnosed with a synchronous atypica...
We still get a piece of tissue from that primary prostate if it does look like it's recurred. But it's starting to be to the point where, when you have an MRI lesion, say, post-radiation, with a rising PSA, and it correlates with the PET scan, then that disease is, for the ...
Aim: The optimal management for early recurrent prostate cancer following radical prostatectomy (RP) in patients with negative prostate-specific membrane antigen positron-emission tomography (PSMA-PET) scan is an ongoing subject of debate. The aim of this study was to evaluate the outcome of salvage...
多项回顾性研究指出,与常规影像相比,PSMA配体前列腺癌PET/CT显像具有较高的检测效能,前列腺癌生化复发已被世界多个地区确立为PSMA配体前列腺癌PET/CT显像的临床适应证。对于高危原发前列腺癌,越来越多的证据表明该显像方式有助于探测隐匿性淋巴结和前列腺癌骨转移;对于原发和复发性前列腺癌的临床适应证,初步研究证实其...
