Objective: The objective was to evaluate outcomes of mammographic architectural distortion (AD) with and without MRI and US correlates.
Methods: A retrospective review of unexplained mammographic AD with subsequent MRI from January 1, 2007 to September 30, 2017 was performed using a reader-based study design. Mammographic, MRI, and US features and outcomes were documented. Truth was based on biopsy results or minimum two-year imaging follow-up. Measures of diagnostic accuracy were calculated.
Results: Fifty-six cases of AD were included: 29 (51.8%) detected on 2D mammogram and 27 (48.2%) detected on digital breast tomosynthesis. Of 35.7% (20/56) with MRI correlate, 40.0% (8/20) were enhancing masses, 55.0% (11/20) were non-mass enhancement (NME), and 5.0% (1/20) were nonenhancing AD. Of eight enhancing masses, 75.0% (6/8) were invasive cancers, and 25.0% (2/8) were high-risk lesions. Of 11 NME, 18.2% (2/11) were ductal carcinoma in situ, 36.4% (4/11) were high-risk lesions, and 45.4% (5/11) were benign. Of 64.3% (36/56) without MRI correlate, 94.4% (34/36) were benign by pathology or follow-up, one (2.8%, 1/36) was a 4-mm focus of invasive cancer with US correlate, and one (1/36, 2.8%) was a high-risk lesion. Of cases without MRI and US correlates, one (3.0%, 1/33) was a high-risk lesion and 97.0% (32/33) were benign. The negative predictive value of mammographic AD without MRI correlate was 97.2% (35/36) and without both MRI and US correlates was 100.0% (33/33).
Conclusion: Mammographic AD without MRI or US correlate was not cancer in our small cohort and follow-up could be considered, reducing interventions.

Generalized Anxiety Disorder (GAD) is characterized by excessive worry and physical symptoms of prolonged anxiety. Patients with subclinical GAD-states (sub-GAD) do not fulfill the diagnostic criteria of GAD, but they often show a disease burden similar to GAD, and the subclinical state may turn into a full syndrome. Neuroinflammation may contribute to changes in brain structures in sub-GAD, but direct evidence remains lacking.

Hemorrhagic stroke occurs due to a rupture of a blood vessel in the brain. This leads to initial mechanical damage at the site of injury and secondary injuries including axonal degeneration (AxD). Since axons are critical for all brain functions, we systematically reviewed studies that focused on axonal degeneration in two major types of hemorrhagic stroke, intracerebral hemorrhage and subarachnoid hemorrhage, to understand how and to what extent AxD develops and to interrogate underlying mechanisms and potential therapeutic targets.

Myelin and myelin water (MW) behavior is becoming increasingly relevant in their role in neurodegenerative diseases. Myelin proton fraction (MPF) and myelin water fraction (MWF) measured with short-TR adiabatic inversion-recovery (STAIR) sequences are potential biomarkers of myelin and MW, respectively, but their repeatabilities are unknown. This study aims to evaluate the repeatability of MPF and MWF measured with the STAIR ultrashort echo time (STAIR-UTE) and STAIR short echo time (STAIR-STE) sequences, respectively.

Background And Purpose: Several studies have shown changes in neurochemicals within the deep-brain nuclei of patients with psychosis. These alterations indicate a dysfunction in dopamine within subcortical regions affected by fluctuations in iron concentrations. Quantitative Susceptibility Mapping (QSM) is a method employed to measure iron concentration, offering a potential means to identify dopamine dysfunction in these subcortical areas.

Neonatal hypoxic-ischemic encephalopathy (HIE) is a significant cause of developmental disorders and permanent central nervous system damage, with functional recovery closely linked to myelin sheath integrity. This study aimed to analyze the expression of pH and the voltage-gated proton channel (Hv1) in the brains of neonatal pigs with HIE at various time points, alongside changes in myelin-related proteins. MRI was employed to localize the basal ganglia and assess pH changes post-hypoxia-ischemia, while immunofluorescence staining was used to evaluate Hv1, myelin basic protein (MBP), myelin oligodendrocyte glycoprotein (MOG), and myelin-associated glycoprotein (MAG).
