Retrospective Analysis of Survival and Adverse Effects Associated With Stereotactic Body Radiation Therapy in 12 Dogs With Hepatocellular Carcinoma

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT This retrospective analysis evaluated 12 dogs with hepatocellular carcinoma (HCC) who received stereotactic body radiation therapy (SBRT). Dogs received between 6 and 25 Grey (Gy) per fraction for 1–5 fractions for a total dose of 13–30 Gy. Eleven patients (92%) experienced acute adverse effects (AE), with the majority being VRTOG grade 2–3 ...

Dual‐scan conformal cone‐beam CT for targeted image‐quality improvement using dynamic collimation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is routinely used for image guidance in radiation therapy, but conventional full‐field CBCT acquisition may expose anatomically irrelevant regions and generate substantial scatter, which degrades soft‐tissue contrast and limits the accuracy of target localization and adaptive radiotherapy ...

The study of characteristics of flat panel detectors without semiconductor conversion layers for therapeutic high-energy X-ray radiation

Nuclear Engineering and Technology
We evaluated a novel 2-D flat-panel detector (FPD) adapting it for megavoltage (MV) therapeutic imaging and radiation QA. The prototype uses a thick dielectric layer to create a semi-transmissive structure, changing and eliminating structure conventional

Risk Factors for Small‐for‐Size Syndrome Grade B/C After Simultaneous Splenectomy in Adult Living‐Donor Liver Transplantation

Annals of Gastroenterological Surgery, Volume 10, Issue 4, Page 1165-1173, July 2026.
In a single‐center cohort of 577 adult LDLT recipients who underwent simultaneous splenectomy, clinically significant SFSS grade B/C (ILTS‐iLDLT‐LTSI 2023) occurred in 18.2% and was associated with inferior graft survival. Multivariate analysis identified MELD ≥ 30, NLR ≥ 4.5, and donor age ≥ 50 years as independent risk factors, which risk rising ...
