A total of 139 patients underwent Ga-68-PSMA-11 PET imaging for prostate cancer: 47 non-time-of-flight (non-TOF) PET/computed tomography, 51 PET/magnetic resonance imaging (MRI) using the standard TOF scatter correction algorithm, and 41 PET/MRI using an improved TOF scatter correction algorithm.
The typical and predictable patterns of spread in prostate cancer are still more prevalent, such as spread to pelvic lymph nodes and bone metastasis, but different patterns of disease spread are becoming more commonly recognized with higher reliability because PSMA imaging allows detection of more typical and atypical lesions than conventional imaging.
These novel PSMA scFv-loaded NBs have proven to be an excellent US contrast agent for imaging PSMA-expressing PCa and have the potential to not only enable efficient and safe molecular imaging but also to serve as a delivery system for targeted PCa therapies.
<b>Methods:</b> In an Institutional Review Board-approved pilot study, initial clinical utility of PET/CT imaging with <sup>18</sup>F-JK-PSMA-7 was directly compared to <sup>68</sup>Ga-PSMA-11 PET/CT in a group of 10 patients with prostate cancer.
In 2017, we used the following scanning protocol for <sup>68</sup>Ga-PSMA-11 PET/CT in patients with recurrent PC: acquisition at 1 h p.i. without further preparations.
Dual-time point PET/CT scanning with [<sup>68</sup>Ga]Ga-PSMA-11 in the diagnosis of prostate cancer (PC) has been advanced as a method to increase detection of PC lesions, particularly at early stages of biochemical recurrence and as a potential means to aid the discrimination between benign and pathological prostate-specific membrane antigen (PSMA) uptake.
A 75-year-old man referred for a second episode of biochemical recurrence of prostate cancer presented an isolated intense prostate-specific membrane antigen-11 uptake from a right lung abnormality.
Prostate-specific membrane antigen (PSMA) continues to be the hallmark biomarker for prostate cancer as it is expressed on nearly all prostatic tumors.
Ga-PSMA PET-CT allows accurate detection of lymphnodal metastases in patients with intermediate-risk and high-risk prostate cancer prior to definitive surgical treatment.
To review the literature to determine the sensitivity and specificity of gallium-68 prostate-specific membrane antigen (<sup>68</sup> Ga-PSMA) positron-emission tomography (PET) for detecting pelvic lymph node metastases in patients with primary prostate cancer (PCa), and the positive predictive value in patients with biochemical recurrence (BCR) after initial curative treatment, and, in addition, to determine the detection rate and management impact of <sup>68</sup> Ga-PSMA PET in patients with BCR after radical prostatectomy (RP).
We undertook a head-to-head comparison of PSMA-targeted <sup>18</sup>F-DCFPyL PET to Na<sup>18</sup>F PET to determine which modality was more sensitive for the detection of lesions suspicious for bone metastases in a group of patients with metastatic PCa.
We developed prostate-specific membrane antigen (PSMA)-targeted low-molecular-weight (LMW) agents for <sup>212</sup>Pb-based TRT of patients with prostate cancer (PC) by evaluating the matching γ-emitting surrogate, <sup>203</sup>Pb.
To compare the diagnostic efficiency of ⁶⁸Gallium labelled prostate-specific membrane antigen positron emission tomography (⁶⁸Ga-PSMA PET) and magnetic resonance imaging (MRI) for staging the lymph node metastases (LNMs) in the prostate cancer.
To assess the performance of [<sup>68</sup>Ga] Ga-prostate-specific membrane antigen conjugate 11 positron emission tomography (PSMA-PET) in detecting PCa lymph node metastasis using pathologic confirmation through sLND.
The aim of this study was to assess the added value of <sup>68</sup>Ga-PSMA-11 PET in predicting lymph node metastasis in men with intermediate- or high-risk prostate cancer.
PSMA PET/CT should be considered to monitor PCa response to chemotherapy to detect early relapse, regardless of prostate-specific antigen levels, increasing the chances of finding low-volume oligoprogressive disease.
A total of 63 patients diagnosed with PCa who underwent (<sup>68</sup>Ga)PSMA 11 PET/CT between April 2019 and June 2019 and who had 5th minute and 1st and 2nd hour images were included in the study.
