Susceptibility-weighted image (SWI) is a T* gradient echo sequence, which is highly sensitive to substances that have magnetic properties. The phase and magnitude of SWI can play an important role in the diagnosis of several diseases. The phase data is highly affected by spatial variations in the main magnetic field of the magnetic resonance imaging (MRI) scanner. The axial acquisition is the frequent plane alignment while acquiring SWI in diagnostic imaging. Clinical requirements often lead to changing of the alignment angles due to variability in patient positioning and anatomy. For many patients undergoing brain MRI, the line of the anterior and posterior commissure AC-PC can vary in direction with respect to the transverse plane of the MRI system. We investigated whether there exist significant effect on phase data of SWI, and this is due to oblique orientation. The obtained results showed significant differences in phase values between axial and anatomically alignments.
Objectives: Pregnant women had a large demand for diagnosis and treatment, but the clinical research was not sufficient, and there were many barriers for pregnant women to participate in clinical research. This study aimed to systematically identify these barriers and facilitators, map them with Theoretical Domains Framework (TDF) and Behavior Change Techniques (BCTs) to inform the development of interventions promoting pregnant women's involvement in clinical research.
Methods: This was a mixed-methods systematic review.
Background: Increased ribosome biogenesis is required for tumor growth. In this study, we investigated the function and underlying molecular mechanism of ribosome biogenesis factor (RBIS) in the progression of non-small cell lung cancer (NSCLC).
Methods: In our study, we conducted a comprehensive analysis to identify key genes implicated in ribosome biogenesis by leveraging a Gene Set Enrichment Analysis (GSEA) dataset.
Background: The national malaria control programmes in Cambodia, Nepal, and Bhutan aim to achieve malaria elimination by 2025-2030. While the vivax malaria burden remains challenging, the consistent decline in falciparum malaria in these countries over the last five years suggests that the goal is achievable. However, unexpected cases in previously falciparum malaria-free districts continue to occur.
In keeping with the historical focus of this special issue of Hippocampus, this paper reviews the history of my development of the SPEAR model. The SPEAR model proposes that separate phases of encoding and retrieval (SPEAR) allow effective storage of multiple overlapping associative memories in the hippocampal formation and other cortical structures. The separate phases for encoding and retrieval are proposed to occur within different phases of theta rhythm with a cycle time on the order of 125 ms.
Rationale And Objectives: To improve the diagnostic recognition of papillary renal neoplasm with reverse polarity (PRNRP) through comprehensive analysis of computed tomography (CT) and magnetic resonance imaging (MRI) findings.
Materials And Methods: A retrospective multi-center study was conducted on patients with pathologically confirmed PRNRPs from 2019 to 2024, encompassing six institutions. Clinical and pathological data were meticulously documented.
