Simultaneous Luminal and Hemodynamic Evaluation of the Cervical Arteries Using Nonenhanced 3D Quantitative Quiescent-Interval Slice-Selective Magnetic Resonance Angiography.
J Magn Reson Imaging
January 2025
Department of Radiology, Endeavor Health, Evanston, Illinois, USA.
Background: Luminal and hemodynamic evaluations of the cervical arteries inform the diagnosis and management of patients with cervical arterial disease.
Purpose: To demonstrate a 3D nonenhanced quantitative quiescent interval slice-selective (qQISS) magnetic resonance angiographic (MRA) strategy that provides simultaneous hemodynamic and luminal evaluation of the cervical arteries.
Study Type: Prospective.

Introduction: Previous research on the visual processing of threats has largely overlooked the Q8 distinct effects of various types of threats, despite evidence suggesting unique brain activation patterns for specific fears. Our study examines the differential effects of threat types on attentional processes, focusing on snakes and blood-injury-injection (BII) stimuli. We sought to test whether these two types of threat stimuli, as taskirrelevant distractors, would lead to similar effects in a visual search task.

Department of Oral and Maxillofacial Surgery, Goa Dental College and Hospital, Bambolim, Goa 403202, India.
Background: Immunoglobulin G4 related disease (IgG4-RD) is an immune-mediated, multifocal, fibroinflammatory disease with varied clinical manifestations. The involvement of head and neck region is infrequent. The objective was to report a case of localized IgG4-RD of mandible that clinically mimicked a lytic lesion.

Robust CD8 T cell responses are critical for the control of HIV infection in both adults and children. Our understanding of the mechanisms driving these responses is based largely on studies of cells circulating in peripheral blood in adults, but the regulation of CD8 T cell responses in tissue sites is poorly understood, particularly in pediatric infections. DNA methylation is an epigenetic modification that regulates gene transcription.

Department of Radiology, Obstetrics and Gynecology Hospital, Fudan University, PR China.
Objectives: To clarify the prenatal magnetic resonance (MR) imaging characteristics of fetal intracranial haemorrhages (ICHs) in a large cohort and correlate them with birth outcomes.
Methods: We retrospectively reviewed MR images of fetuses with ICH on screening ultrasound (US) on picture archiving communication system (PACS) servers within a nearly ten-year period from two medical tertiary centres. The indications, main abnormal findings and coexistent anomalies were recorded by two experienced radiologists with census readings.
