Colorectal Cancer: A Landscape of New Potential Radiopharmaceuticals

In recent years, advancements in imaging techniques have contributed to a gradual yet promising reduction in colorectal cancer-related mortality. Among these, positron emission tomography (PET), particularly in combination with computed tomography using 2-deoxy-2-[fluorine-18]fluoro-d-glucose ([18F]FDG), has emerged as a valuable non-invasive diagnostic tool. However, the application of [18F]FDG-PET in colorectal cancer remains limited because of the radiotracer’s pharmacokinetics and metabol...

Euclid preparation LXXVIII. Full-shape modelling of two-point and three-point correlation functions in real space

We investigated the accuracy and range of validity of the perturbative model for the two-point (2PCF) and three-point (3PCF) correlation functions in real space in view of the forthcoming analysis of the Euclid mission spectroscopic sample. We took advantage of clustering measurements from four snapshots of the Flagship I N-body simulations at z = {0.9,1.2,1.5,1.8}, which mimic the expected galaxy population in the ideal case, i.e. in the absence of observational effects such as purity and co...

The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes

We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027, the SO Small Aperture Telescope (SAT) complement will be doubled from three to six telescopes, including a doubling of the detector count in the 93 GHz and 145 GHz channels to 48,160 detectors. Combined with a planned extension of the survey duration to 2035, this expansion will significantly enhance SO's...

Incidental CT findings on PET/SPECT with clinical and potential future risks

Coregistration CT in PET/CT and SPECT/CT is a transmissive imaging technique performed immediately before the emission study with the patient in the same position, eliminating temporal mismatches typical of software-based image fusion. Its primary purposes are attenuation correction through a densitometric map and anatomical localization of PET or SPECT abnormalities. Although coregistration CT can improve the specificity of nuclear medicine findings, it is not a full diagnostic CT because it...

Euclid preparation - LXXXVIII. 3D reconstruction of the cosmic web with Euclid Deep spectroscopic samples

The ongoing Euclid mission is aimed at measuring spectroscopic redshifts for approximately two million galaxies using the H alpha line emission detected in near-infrared slitless spectroscopic data from the Euclid Deep Fields, leveraging both the red and blue grisms. These measurements will reach a flux limit of 5 x 10(-17) erg cm(-2) s(-1) in the redshift range 0.4 < z < 1 .8, paving the way to numerous scientific investigations involving galaxy evolution, extending well beyond the mis...
