    Article Snippet: Glypican-3 (GPC3) is markedly overexpressed in hepatocellular carcinoma (HCC) and not expressed in normal liver tissues.. In this study, a novel peptide PET imaging agent ([18F]AlF-NOTA-IPB-GPC3P) was developed to target GPC3 expressed in tumors.. The overall radiochemical yield of [18F]AlF-NOTA-IPB-GPC3P was 10–15 %, and its lipophilicity, expressed as the logD value at a pH of 7.4, was − 1.18 ± 0.06 (n = 3).

    Article Snippet: The development of fibrosis after injury to the brain or spinal cord limits the regeneration of the central nervous system in adult mammals.. However, the extent of fibrosis in the injured brain has not been systematically investigated in mammals in vivo.. This study aimed to assess whether [18F]AlF-FAPI-42-based cerebral positron emission tomography (PET) can be utilized to assess the extent of fibrosis in ischemic regions of the brain in vivo.

    Article Snippet: PD-L1 is expressed in many tumors but rarely in normal tissues, therefore, it can be a target of PET imaging.. In this work, we developed new peptide-based PET probes [18F]AlF-PAI-PDL1p and [68Ga]Ga-PAI-PDL1p with yields of 20–25 % and 40–55 %, respectively.. [18F]AlF-PAI-PDL1p and [68Ga]Ga-PAI-PDL1p were synthesized within 30 min with high molar activities.

    Article Title: Guidelines for the Diagnosis and Clinical Management of Cavernous Malformations of the Brain and Spinal Cord: Consensus Recommendations Based on a Systematic Literature Review by the Alliance to Cure Cavernous Malformation Clinical Advisory Board Experts Panel.
    Article Snippet: For suspected spinal CMs, a susceptibility-sensitive sequence such as 3-dimensional Multi-Echo Data Image Combination (Siemens) should be used in addition to standard T1-weighted and T2-weighted MRI sequences as this can help show small CMs similar to what SWI does in the brain.65,66 Although FCM cases often harbor spinal CMs, it is unclear if the diagnosis of occult lesions in asymptomatic cases will alter clinical management.66,67
