Artificial intelligence in the diagnosis of gastro‐entero‐pancreatic neuroendocrine neoplasms: Potential benefits and current limitations

open access: yesJournal of Neuroendocrinology, Volume 37, Issue 11, November 2025.
Gastro‐entero‐pancreatic neuroendocrine neoplasms (GEP‐NENs) exhibit substantial clinical heterogeneity and necessitate a multidisciplinary, personalized approach. Artificial intelligence (AI), through advanced imaging analysis and predictive modeling, offers new opportunities to support diagnosis and guide management.

Triple‐energy photon‐counting x‐ray imaging for bone‐strontium estimation: A simulation study

open access: yesMedical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Strontium quantification in bone is clinically relevant but typically requires specialized stand‐alone systems. Photon‐counting detectors offer energy‐resolved imaging that may enable low‐dose estimation of both strontium concentration and bone mineral density in a single acquisition.

Photon Absorptiometry in Three Component Systems [PDF]

open access: yes, 1990
The non-invasive measurement of the mass of bone is a clinically relevant problem. The bone is one component of a composite system. At the spine it may include fat, lean and bone mineral.

ODIASP: An Open‐Source Software for Automated SMI Determination—Application to an Inpatient Population

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 4, August 2025.
ABSTRACT Background The diagnosis of malnutrition has evolved with the GLIM recommendations, which advocate for integrating phenotypic criteria, including muscle mass measurement. The GLIM framework specifically suggests using skeletal muscle index (SMI) assessed via CT scan at the third lumbar level (L3) as a first‐line approach.

Photon-photon interaction mediated by a virtual photon in a nonlinear microcavity

open access: yes, 2023
Interactions between single photons play a crucial role in both fundamental physics and quantum technologies. So far, only a few demonstrations of photon interactions have been accomplished using quantum emitters that are strongly coupled to optical ...

Reference Data and Predictors of HR‐pQCT‐Derived Muscle Density and Its Prediction of Physical Performance

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 4, August 2025.
ABSTRACT Background There is increasing awareness of a role for muscle composition in sarcopenia and cachexia. Computed tomography (CT)–based measures of muscle density (MusD) are commonly used to indicate composition, with a decrease in MusD reflecting an increase in muscle fat infiltration. The current study explored predictors of MusD acquired using

Body composition measures assessed by bioelectrical impedance analysis and dual-energy X-ray absorptiometry in a sample of Brazilian adults and older adults

open access: yesFrontiers in Nutrition
IntroductionBioelectrical impedance analysis (BIA) is a common technique for assessing body composition in clinical and epidemiological settings. However, its accuracy is limited compared to reference methods such as dual-energy X-ray absorptiometry (DXA)
