Recent applications of magnetic iron oxide nanoparticles for cerebral blood volume quantification in functional magnetic resonance imaging

open access: yesIbrain, Volume 11, Issue 4, Page 439-456, Winter 2025.
This study explores the recent advances in the use of iron oxide nanoparticles (IONPs) in functional MRI (fMRI) for studying brain functions, specifically cerebral blood volume (CBV) measurements. It covers fMRI techniques, magnetic nanoparticle synthesis, coating methods, and their applications in CBV imaging, in comparison to other contrast agents in

Development of a method for preparing octreotide derivative for diagnosis of neuroendocrine tumors

open access: yesБюллетень сибирской медицины, 2019
Currently the development of technologies for labeling somatostatin with technetium-99m for diagnosing radionuclide neuroendocrine tumors is under way. Somatostatin analogues are binded with technetium99m only by the preliminary addition of a chelating ...

CTHRC1 promotes bone metastasis in prostate cancer

open access: yesInternational Journal of Cancer, Volume 157, Issue 11, Page 2399-2412, 1 December 2025.
What's New? The mechanisms driving bone metastasis in prostate cancer are still unclear, and predicting markers have not yet been identified. Based on the biological characterization of prostate cancer cell lines and integrated data analysis of clinical samples, the authors identified CTHRC1 as a candidate gene regulating prostate cancer bone ...

Measurement of renal cortex perfusion: A direct comparison of arterial spin labelling magnetic resonance imaging and [15O]H2O positron emission tomography

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 6, Page 2537-2549, December 2025.
Abstract Purpose Reliable information about renal blood supply is important to understand kidney physiology and diseases. Arterial spin labeling MR (ASL‐MR) imaging and [15O]H2O positron emission tomography (PET) can noninvasively measure tissue perfusion but have never been directly compared.

Hepatobiliary scintigraphy with SPET in the diagnosis of bronchobiliary fistula due to a hydatid cyst [PDF]

open access: yes, 2015
In this report, we present the application of hepatobiliary scintigraphy using Tc-99m mebrofenin in the diagnosis of bronchobiliary fistula caused by a liver hydatid cyst, which penetrated the diaphragm. Hepatobiliary scintigraphy noticeably depicted the

Synthesis and Biological Evaluation of Novel Mixed-Ligand 99mTc-Labeled Anthraquinone Complexes as Potential DNA-Targeted Imaging Agents

open access: yesInorganics
Anthraquinones are molecules with numerous biological properties that can act as DNA intercalators and topoisomerase IIa inhibitors. In this work, the development of technetium-99m radiotracers was pursued via the technetium-tricarbonyl “2 + 1” mixed ...
