    Abstract A 46-year-old man with end-stage renal disease and renal cell carcinoma underwent F-FDG PET/CT for initial staging followed by F-PSMA-1007 PET/CT. Unlike F-FDG, which undergoes renal clearance, F-PSMA-1007 undergoes hepatobiliary clearance and thus generates superior quality images. F-PSMA-1007 PET/CT showed intense tracer-avid left renal mass lesion (FDG nonavid); lytic bone lesions (FDG avid) and single liver lesion (FDG nonavid). This case highlights the superiority of F-PSMA-1007 over F-FDG PET/CT in identifying primary lesion as well as metastatic sites in case of renal cell carcinoma even in the presence of end-stage renal disease.

    Abstract A 72-year-old man, who is known with a case of metastatic carcinoma of the breast, was referred for F-PMSA 1007 PET/CT with clinical suspicion of synchronous prostate cancer. F-PSMA 1007 PET/CT scan detected no abnormal tracer concentrating lesion in the prostate gland; however, abnormal tracer concentration was noted in soft tissue lesions in left breast, metastatic lymph nodes, and skeletal lesions. Compared with F-FDG PET/CT, more bone lesions were detected on F-PSMA 1007 imaging. The findings of our case open the possibility of imaging metastatic breast cancer with F-PSMA 1007 in men.

    Abstract Abstract: We describe a case of 68Ga-prostate-specific membrane antigen PET/CT scan with focal tracer concentration in the lung without any abnormalities in the CT part. 18F-FDG focal uptake in lungs without corresponding CT lesions is described. Two possible mechanisms proposed to explain this finding in FDG PET/CT scans are iatrogenic pulmonary microembolism and 18F-FDG-avid infection or inflammation that precedes structural findings. Logically, these proposed mechanisms seem to be applicable to 68Ga-prostate-specific membrane antigen as well. In our case, there were no features of any lung infection/inflammation, and the most plausible explanation would be iatrogenic microembolism.

    Abstract A 64-year-old man with a known case of right parietal lobe glioblastoma multiforme operated on in August 2018 was referred for F-FDG PET/CT with a clinical suspicion of recurrence. He underwent F-FDG and F-PSMA 1007 scans. Both the scans showed intense tracer uptake in right parietal lobe lesion, which concurred with MRI findings of recurrent disease and was later proven on histopathologic examination as recurrence. Our case highlights the feasibility of F-PSMA 1007 PET/CT imaging of suspected glioblastoma recurrence. Considering its similarity to PSMA-617, it may be used as a surrogate imaging tracer for potential theranostic application using alpha or beta emitters.

    Abstract A 64-year-old woman with metastatic breast cancer on follow-up had suspicious recurrent brain metastases. She underwent F-FDG PET/CT, F-PSMA 1007 brain PET/CT, and brain MRI. F-PSMA 1007 showed intense tracer localization in the suspected recurrent brain metastasis in right parietal lobe and also picked up 2 more metastatic brain lesions, which had concurrent findings of metastasis in subsequent MRI. Our case highlights the feasibility of F-PSMA 1007 PET/CT imaging of brain metastases from nonprostate cancers. It may be used as surrogate imaging tracer for potential theranostic application using alpha or beta emitters considering its similarity to PSMA-617.

    Abstract A 60-year-old man with suspected right renal cell carcinoma underwent F-FDG PET/CT and F prostate-specific membrane antigen (PSMA) 1007 PET/CT scan. Compared with the F-FDG PET/CT scan, F-PSMA 1007 PET/CT showed intense tracer concentration in the primary tumor in the right kidney and intense tracer concentration consistently in all lung nodules. Unlike noted in previous pilot studies with Ga-PSMA, we observed that the primary renal tumor also showed intense tracer avidity with F-PSMA 1007. F-PSMA 1007 PET/CT may provide preoperative insight into possible etiology, histopathological probability of tumor type, staging information, and theranostic potentials in evaluation of suspected renal cell carcinoma.

    Abstract A 74-year-old man with suspected prostate cancer and a previously negative transrectal ultrasound-guided prostate biopsy underwent Ga-PSMA PET/CT. Scan showed no abnormal tracer concentration in enlarged prostate gland to suggest prostate cancer. Note was made of an incidentally detected well defined soft tissue lesion in the greater curvature of the stomach with moderate tracer concentration in its intraluminal portion. Biopsy of the lesion revealed gastrointestinal stromal tumor.
