From: The image quality and feasibility of solitary delayed [68 Ga]Ga-PSMA-11 PET/CT using long field-of-view scanning in patients with prostate cancer

Fig. 3

Delayed images showed additional lesion detection in prostate region. [68 Ga]Ga-PSMA LFOV PET/CT in a 78-year-old primary PCa patient after TURP (tiles A–F). The high radioactivity within the bladder and enlarged prostatic urethra impeded the detection of PSMA-avid lesions in early images (tiles B and E). A locally lesion at the left lobe of prostate gland was discernible in delayed image, with a SUVmax value of 9.6 (tile C). In addition, late scan detected invasion of left seminal vesicle (tile F), which was not distinguishable in the early scan, the SUVmax value was 1.7 in the early image, while the delayed image showed a SUVmax value up to 15.0. [68 Ga]Ga-PSMA LFOV PET/CT in a 70-year-old BCR patient (tiles G–I). A locally recurrent lesion at the prostate bed was detected at the delayed images, with a SUVmax value of 25.8 (tile I), which was unclear in early image due to the high radioactivity within the bladder (tile H)
