From: 68Ga-PSMA-PET/CT for the evaluation of liver metastases in patients with prostate cancer
Example of 68Ga-PSMA-positive liver metastases in a PC patient with a recurrent acinar adenocarcinoma. a, b: 68Ga-PSMA-PET/CT of a 68-year-old patient with a recurrent acinar adenocarcinoma of the prostate. At initial diagnosis in 2007, the GS was 5 + 5. The patient received primary radiotherapy and undergone chemotherapy as well as androgen-deprivation therapy. The serum PSA was 606 ng/ml at the time of examination. Besides disseminated osseous metastases (such as in a vertebral body, blue arrows) and a singular lymph node metastasis in the axilla, the PET/CT (a) revealed small-nodular, PSMA-positive liver metastases in all segments, with SUVmax-values up to 26.3 (exemplary in segments VII/VIII, green arrows). In contrast-enhanced CT (b), liver metastases appear ill-defined and hypodense compared to the liver, typical for hypovascular metastases.
