Article Abstract
Purpose: This study aimed to explore the imaging value of 68 Ga-FAPI-04 PET/CT in synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome and compare it with that of 99m Tc-MDP bone scan.
Methods: Nineteen participants with SAPHO syndrome underwent 68 Ga-FAPI-04 PET/CT and 99m Tc-MDP bone scan. Demographic data and clinical features were recorded, SAPHO imaging features were analyzed, and the osteoarticular lesion detection rate in both methods was calculated.
Results: This prospective study recruited 4 men and 15 women aged 52.4 ± 8.6 years. The anterior chest wall was involved in all participants (100%). Palmoplantar pustulosis was the most common (36.8%) skin symptom. 99m Tc-MDP bone scan and 68 Ga-FAPI-04 PET/CT together detected 84 osteoarticular lesions, of which 91.7% (77/84) were detected by the former and 96.4% (81/84) by the latter. Furthermore, 68 Ga-FAPI-04 PET/CT detected 5 cases of knee and hip joint synovitis.
Conclusions: 68 Ga-FAPI-04 PET/CT was more sensitive than 99m Tc-MDP bone scan when evaluating osteoarticular lesions in SAPHO syndrome and could also evaluate synovial lesions. 68 Ga-FAPI-04 PET/CT could be a good imaging method for SAPHO syndrome but requires further verification in a more extensive research cohort.

Background: Bone metastases of lung cancer typically indicate disease progression and poor prognosis. Early and accurate detection is crucial for staging, treatment planning, and prognostic evaluation. This study aimed to compare the diagnostic value of gallium 68-labeled fibroblast-activation protein inhibitor-04 ([Ga]Ga-FAPI-04) and fluorine 18-labeled fluorodeoxyglucose ([F]FDG) positron-emission tomography/computed tomography (PET/CT) imaging in detecting bone metastases in lung cancer.

Background: The precise differentiation of recurrent glioma from treatment-related changes, such as pseudoprogression or radiation necrosis, is essential for treatment planning and remains a significant challenge. Fibroblast activation protein (FAP) expressed by cancer-associated fibroblasts can be targeted with PET tracers for in vivo visualization and quantification. This study aims to evaluate the diagnostic and prognostic effectiveness of FAP expression in patients with potential recurrent glioma by directly comparing [gallium-68] FAP inhibitor-04 and [fluorine-18] fluoroethyl-L-tyrosine PET/CT imaging.

Purpose: Radiation-induced injury to the salivary glands is a recognized complication of radiotherapy for head and neck cancer. However, comprehensive diagnosis of salivary gland dysfunction remains challenging. Therefore, we conducted a retrospective study to assess the effectiveness of [Ga]Ga-FAPI-04 PET/CT in diagnosing salivary gland radiation injury in patients with head and neck cancer.

Purpose: To assess the efficacy of [Ga]Ga-FAPI-04 PET/CT in detecting hepatic vascular-associated mesenchymal tumor (HVAMT), including hepatic hemangioma (HH), hepatic epithelioid hemangioendothelioma (HEHE), and hepatic perivascular epithelioid cell tumor (PEComa), and to compare its efficacy with that of [F]FDG PET/CT.
Methods: A retrospective analysis was conducted on 31 cases of HVAMTs from a prospective parent study (ChiCTR2000039099), including 25 cases of HH (35 lesions), 2 cases of HEHE (18 lesions), and 4 cases of PEComa (6 lesions). All patients underwent both [¹⁸F]FDG and [⁶⁸Ga]Ga-FAPI-04 PET/CT within one week of each other.

Fibroblast activation protein (FAP), highly overexpressed in cancer-associated fibroblasts (CAFs), is crucial in tumor pathogenesis and progression, making it an important target for diagnosis and therapy. This study presents the design of a series of FAP inhibitors (FAPIs) derived from UAMC-1110 derivative, modified with zwitterions and polyethylene glycol (PEG). The novel Ga-labeled tracers show improved pharmacokinetics compared to Ga-FAPI-04.
