The damage caused by glaucoma has been extensively evaluated at the level of the retina and optic nerve head. Many advances have been shown in this field in the last decades. Recent studies have also proved degenerative changes in the brain involving the intracranial optic nerve, lateral geniculate nucleus, and visual cortex. Moreover, these brain abnormalities are also correlated with clinical, optic nerve head, and visual field findings. In this review, we critically evaluate the existing literature studying the use of magnetic resonance imaging in glaucoma, and we discuss issues related to how magnetic resonance imaging results should be incorporated into our clinical practice.

Introduction: Alzheimer's disease (AD) in Down syndrome (DS) is associated with changes in brain structure. It is unknown if thickness and volumetric changes can identify AD stages and if they are similar to other genetic forms of AD.
Methods: Magnetic resonance imaging scans were collected for 178 DS adults (106 nonclinical, 45 preclinical, and 27 symptomatic).
Usefulness of Myelin Quantification Using Synthetic Magnetic Resonance Imaging for Predicting Outcomes in Patients With Acute Ischemic Stroke.
Stroke

Department of Clinical Neuroscience and Therapeutics, Graduate School of Biomedical and Health Sciences, Hiroshima University, Japan (M.T., T.N., S.A., H.M.).
Background: Synthetic magnetic resonance imaging (MRI) is an innovative MRI technology that enables the acquisition of multiple quantitative values, including T1 and T2 values, proton density, and myelin volume, in a single scan. Although the usefulness of myelin measurement with synthetic MRI has been reported for assessing several diseases, investigations in patients with stroke have not been reported. We aimed to explore the utility of myelin quantification using synthetic MRI in predicting outcomes in patients with acute ischemic stroke.

The ZSM-5 zeolite is the key active component in high-severity fluid catalytic cracking (FCC) catalysts and is routinely activated by phosphorus compounds in industrial production. To date, however, the detailed structure and function of the introduced phosphorus still remain ambiguous, which hampers the rational design of highly efficient catalysts. In this work, using advanced solid-state NMR techniques, we have quantitatively identified a total of seven types of P-containing complexes in P-modified ZSM-5 zeolite and clearly revealed their structure, location, and catalytic role.

Department of Radiology, University of Medicine and Pharmacy of Craiova, Craiova, ROU.
Background: Cervical cancer is considered one of the most common gynecological malignancies with an increased incidence in developing countries. Magnetic resonance imaging (MRI) plays a valuable role in staging cervical cancer and providing valuable information necessary for selecting the appropriate treatment plan, while closely correlating with the prognosis of the patient.
Objective: The aim of this study is to assess the diagnostic value of diffusion-weighted imaging (DWI) in the preoperative loco-regional staging of cervical carcinoma.
Significance of Diagnostic Findings of Placenta Percreta by Magnetic Resonance Imaging and Pathological Correlation.

Placenta percreta is a rare form of disorder found in the spectrum of placenta accreta and represents a considerable cause of maternal complications with an increase in mortality. The radiologist's role is essential due to the support of images acquired by magnetic resonance imaging, given their high sensitivity and specificity to predict the degree of placental invasion in substitution or accompaniment of the ultrasound study between 28 and 32 weeks of gestation. We present the case of a 29-year-old patient who was in her third pregnancy with a history of two cesarean sections at the ISSSTE Regional Hospital in Monterrey, Nuevo León.
