Cancers, Vol. 12, Pages 1868: Development of Antibody Immuno-PET/SPECT Radiopharmaceuticals for Imaging of Oncological Disorders—An Update Cancers doi: 10.3390/cancers12071868 Authors: Jonatan Dewulf Karuna Adhikari Christel Vangestel Tim Van Den Wyngaert Filipe Elvas Positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are molecular imaging strategies that typically use radioactively labeled ligands to selectively visualize molecular targets. The nanomolar sensitivity of PET and SPECT combined with the high specificity and affinity of monoclonal antibodies have sh...

Conclusion: The high accumulation of activity in the tumor and fast clearance from background organs was a common favorable characteristic of PSMA radioligands modified with ibuprofen as albumin-binding entity. 177Lu-Ibu-DAB-PSMA emerged as the most promising candidate; hence, more detailed preclinical investigations with this radioligand are warranted in view of a clinical translation.

In this study, a PNA sequence that undergoes complementary binding to miR-155 was labeled with 99mTc to evaluate whether the tracer could visualize the expression of miR-155 in breast cancer. Both antisense PNA (anti-PNA, fully complementary bound to human mature miR-155, referred to as "anti-PNA-155") and mismatched PNA (referred to as "mis-PNA") single strands containing 23-mer were synthesized. The relative expression of miR-155 in MCF-7 cells and tumors was higher than that in MDA-MB-231 cells and tumors. Single-photon emission computed tomography (SPECT) scan showed that radioactivity mainly accumu...

AbstractMetabolic bone volume (MBV), standardized uptake value (SUV), and total bone uptake (TBU) are new imaging biomarkers for quantitative bone single-photon emission computed tomography/computed tomography. The purpose of this study was to validate the quantitative accuracy and utility of MBV, SUVmean, and TBU for the assessment of bone metastases in prostate cancer. We used a bone-specific phantom with four hot spheres (φ = 13, 17, 22, 28 mm) filled with different Tc-99 m activities to simulate uptake ratios of 3 and 7, corresponding to normal and metastatic values. We calculated the error ...

The past two decades have brought impressive advancements in immune modulation, particularly with the advent of both cancer immunotherapy and biologic therapeutics for inflammatory conditions. However, the dynamic nature of the immune response often complicates the assessment of therapeutic outcomes. Innovative imaging technologies are designed to bridge this gap and allow non-invasive visualization of immune cell presence and/or function in real time. A variety of anatomical and molecular imaging modalities have been applied for this purpose, with each option providing specific advantages and drawbacks. Anatomical methods...

Conclusions: All compound were successfully prepared. All final products exhibited high stability in human serum and saline, as well as selective uptake in cardiomyocyte cells in vitro. 18F-HX01 and 18F-HX06 display high and persistent cardiac uptake over 2 h with high myocardium-to-lung and myocardium-to-liver ratio in healthy mice in PET imaging, which were also observed in biodistribution studies. Advancement of these radiotracers for MPI imaging is currently underway.Fig 1. Synthesis route for the reference standards, precursors and radio-labeled products.Fig 2.
