(68)Ga-labeled TMTP1 radiotracer for PET imaging of cervical cancer.

Molecular imaging enables visualization and characterization of biological processes that influence tumor behavior and response to therapy. The TMTP1 (NVVRQ) peptide has shown remarkable affinity to highly metastatic tumors and and its potential receptor ...

Automated radiosynthesis of [(11)C]CPPC for in-human PET imaging applications.

The macrophage colony-stimulating factor 1 receptor (CSF1R) is almost exclusively expressed in microglia, representing a biomarker target for imaging of microglia availability. [[11] C]CPPC has specific binding affinity to CSF1R and suitable kinetic properties ...

Radiodifluoromethylation of well-functionalized molecules.

The strategic installation of a [[18] F]fluorine atom at the specific position of the lead molecule is a never-ending challenge for radiochemists in their endeavour to develop novel positron emission tomography (PET) imaging applications. Although the ...

Case report: [(18)F]FAPI-42 PET/CT visualize primary adenoid cystic carcinoma not detected by [(18)F]FDG.

Adenoid cystic carcinoma (ACC) is a rare salivary gland cancer. Still, its growth and invasion progress is slow, and its hematogenous metastasis is ACC’s most common distant metastasis. Because of the broad expression and low background uptake ...

Subregion-specific (18)F-FDG PET-CT radiomics for the pre-treatment prediction of EGFR mutation status in solid lung adenocarcinoma.

This study aimed to assess the efficacy of fluor-18 fluorodeoxyglucose ([18] F-FDG) PET/CT using sub-regional-based radiomics in predicting epidermal growth factor receptor (EGFR) mutation status in pretreatment patients with solid lung adenocarcinoma. ...

[(99m)Tc]Tc-labeled cyc-DX600-HYNIC as a SPECT probe for ACE2-specific pancreatic cancer imaging.

As a regulator in renin-angiotensin-aldosterone system, angiotensin-converting enzyme 2 (ACE2) closely correlated with tumor progression of pancreatic cancer, meantime, was easily affected by a variety of factors. [[99m] Tc]Tc-cyc-DX600 SPECT was established ...
