A Qualitative Review of Clinical Decision‐Making Using [99mTc]Tc‐Mercaptoacetyltriglycine Renal Scintigraphy in Patients With Malignant Ureteral Obstruction

Journal of Medical Radiation Sciences
Introduction Urinary drainage (ureteral stenting or percutaneous nephrostomy) is commonly used for malignant ureteral obstruction (MUO), but optimal indications remain unclear. [99mTc]Tc‐mercaptoacetyltriglycine (MAG3) renal scintigraphy assesses urinary

Hair radioactivity as a measure of exposure to radioisotopes [PDF]

, 1972
Since many radioisotopes accumulate in hair, this tropism was investigated by comparing the radioactivity of shaved with plucked hair collected from rats at various time intervals up to 24 hrs after intravenous injection of the ecologically important ...

Multi‐fidelity Monte Carlo fusion for BNCT dose calculation using a dual‐branch network

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background Boron neutron capture therapy (BNCT) is a binary radiotherapy that selectively kills tumor cells. Its clinical implementation relies on Monte Carlo (MC)‐based treatment planning systems, which are time‐consuming and limit clinical workflow efficiency.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

A Multicenter Non‐Inferiority Randomized Controlled Trial of Sentinel Lymph Node Biopsy in Early Breast Cancer: Conventional Dual Tracer Versus Superparamagnetic Iron Oxide

World Journal of Surgery, Volume 50, Issue 9, Page 2531-2538, September 2026.
The gold standard for detecting sentinel lymph node (SLN) in early breast cancer is combined use of radioisotope and blue dye. A newer agent, superparamagnetic iron oxide (SPIO), was developed to address the challenges faced with the traditional method.

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, Volume 55, Issue 5, Page 721-729, September/October 2026.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244 Cm sources, and come with severe concerns on radiation safety and isotope availability.
