High resolution Raman microscopy and imaging to propose a jarosite formation process in the MIL 090030 Martian Meteorite.

Jarosite is an iron sulphate that has been found in different Martian meteorites as well as on the Martian surface. In most of the cases, this mineral was detected related to olivine grains. In this work the Miller Range 090,030 Martian Nakhlite (MIL 090030) has been analysed by high resolution Raman microscopy and imaging in areas where jarosite was present.

Characterization of atmospheric aerosols in the Antarctic region using Raman Spectroscopy and Scanning Electron Microscopy.

The non-destructive spectroscopic characterization of airborne particulate matter (PM) was performed to gain better knowledge of the internal structures of atmospheric aerosols at the particle level in the Antarctic region, along with their potential sources. PM and soil samples were collected during the 2016-2017 austral summer season at the surroundings of the Spanish Antarctic Research Station "Gabriel de Castilla" (Deception Island, South Shetland Islands). PM was deposited in a low-volume sampler air filter.

Deep-Learning-Based Artificial Intelligence for PI-RADS Classification to Assist Multiparametric Prostate MRI Interpretation: A Development Study.

Background: The Prostate Imaging Reporting and Data System (PI-RADS) provides guidelines for risk stratification of lesions detected on multiparametric MRI (mpMRI) of the prostate but suffers from high intra/interreader variability.

Purpose: To develop an artificial intelligence (AI) solution for PI-RADS classification and compare its performance with an expert radiologist using targeted biopsy results.

Study Type: Retrospective study including data from our institution and the publicly available ProstateX dataset.

Quality of Prostate MRI: Is the PI-RADS Standard Sufficient?

Rationale And Objective: The Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) published a set of minimum technical standards (MTS) to improve image quality and reduce variability in multiparametric prostate MRI. The effect of PIRADSv2 MTS on image quality has not been validated. We aimed to determine whether adherence to PI-RADSv2 MTS improves study adequacy and perceived quality.
