Deep Learning to Simulate Contrast-Enhanced MRI for Evaluating Suspected Prostate Cancer.

Background Multiparametric MRI, including contrast-enhanced sequences, is recommended for evaluating suspected prostate cancer, but concerns have been raised regarding potential contrast agent accumulation and toxicity. Purpose To evaluate the feasibility of generating simulated contrast-enhanced MRI from noncontrast MRI sequences using deep learning and to explore their potential value for assessing clinically significant prostate cancer using Prostate Imaging Reporting and Data System (PI-RADS) version 2.1.

Reductive Removal of Antimony from Wastewater by a UV/Sulfite Process: Targeted Recovery of Strategic Metalloid Antimony.

The removal of antimony from wastewater using traditional methods such as adsorption and membrane filtration generates large amounts of antimony-containing hazardous wastes, posing significant environmental threats. This study proposed a new treatment strategy to reductively remove and recover antimony from wastewater using an advanced UV/sulfite reduction process in the form of valuable strategic metalloid antimony (Sb(0)), thus preventing hazardous waste generation. The results indicated that more than 99.

Comprehensive Passivation of Surface and Bulk Defects in Perovskite for High Efficiency Carbon-Based CsPbI3 Solar Cells.

Carbon-based perovskite solar cells (C-PSCs) have the advantages of high stability and low cost, but their mean efficiency has become an obstacle to commercialization. Defects, which are widely distributed on the surface and bulk of films, are an important factor in C-PSCs for low efficiency. The conventional post-treatment method through forming a low-dimensional (LD) perovskite layer usually fails in manipulating the bulk defects.

Gastrin-Releasing Peptide Receptor Targeting PET/CT With 68Ga-NOTA-RM26 in the Assessment of Glioma and Combined Multiregional Biopsies.

Purpose: The aim of this study was to investigate the value of 68Ga-NOTA-RM26 (68Ga-RM26), a gastrin-releasing peptide receptor-targeting antagonist labeled with the radionuclide 68Ga, in the diagnosis of high-grade gliomas and in combination with multiregional biopsies using PET/CT.

Patients And Methods: After institutional review board approval and informed consent, a total of 35 patients with suspected glioma lesions were enrolled in this study. All patients underwent 68Ga-RM26 PET/CT scans within 2 weeks before surgery.
