Hybrid contrast-enhanced CT (with iodinated contrast bolus timed to maximize pulmonary arterial visualization) and F-18 DCFPyL PSMA-PET images. Contrast CT images (A, B) show an eccentric filling defect in the superior lingula segmental artery of the left lung upper lobe (red arrow). This is concordant with moderately intense PSMA radiotracer expression (black arrows on axial PET-only images, C, and on whole-body maximum intensity projection image, E). Fused PET and contrast-enhanced CT axial image (D) also confirm the lesion (red arrow). No other site of PSMA expressing metastasis is evident on whole-body imaging (E).
Is Pylarify better than Ga-68 PSMA-11 for prostate cancer imaging?

Images of a 69-year-old woman with endometrial cancer, grade 1 endometrioid adenocarcinoma, T1aN0M0, stage IA. Sagittal (a) and axial (b) T2-weighted MRI show an endometrial tumor (arrow), without deep myometrial invasion. The tumor (arrow) is hyperintense on diffusion-weighted imaging (c) and hypointense on the ADC map (d). The ADCmin of the tumor was 0.45 × 10−3 mm2/s, and the ADCmean was 0.58 × 10−3 mm2/s. PET (e) and PET/MRI fusion images (f) show intense FDG uptake of the tumor (arrow). The SUVmax of the tumor was 12.5, MTV was 3.9 mL, and TLG was 29 g.
