Secondary Aortoduodenal Fistula Diagnosed after Repeated Gastrointestinal Bleeding Episodes in a Patient With Prior Aortic Graft Surgery

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Secondary aortoduodenal fistula (sADF) is a rare but life‐threatening complication after aortic graft surgery. Diagnosis is often challenging, particularly when contrast‐enhanced computed tomography (CT) and endoscopy results are inconclusive. We report a case in which diagnosis was challenging due to contrast media allergy and non‐diagnostic ...

^99mTc Labelling Strategies for the Development of Potential Nitroimidazolic Hypoxia Imaging Agents

Inorganics, 2019
Technetium-99m has a rich coordination chemistry that offers many possibilities in terms of oxidation states and donor atom sets. Modifications in the structure of the technetium complexes could be very useful for fine tuning the physicochemical and ...

CTHRC1 promotes bone metastasis in prostate cancer

International 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 ...

Effects of radiofrequency ablation on individual renal function: assessment by technetium-99m mercaptoacetyltriglycine renal scintigraphy. [PDF]

, 2006
We quantitatively evaluated total and individual renal function by technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) renal scintigraphy before and after radiofrequency ablation (RFA) of renal tumors.

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

Magnetic 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.
