Purpose: Occipital condyle fractures (OCFs) are classified by the Anderson and Montesano system into Type I (comminuted, minimally displaced), Type II (stable, associated with basilar skull fractures), and Type III (unstable avulsion fractures). We retrospectively analyzed 24,986 cervical spine CT examinations of emergency department patients over five years to determine the incidence and characteristics of OCFs, mechanism of injury, and associated intracranial and cervical spine injuries.
Methods And Materials: The study was IRB-approved and HIPAA compliant.
The Canadian Cervical Spine Rule, a clinical decision-making tool for patients post-trauma is often interpreted as recommending cervical spine computed tomography in patients ≥ 65 years old, who sustain a dangerous mechanism of injury, and/or have extremity paresthesias. We retrospectively reviewed 6 years' of emergency department cervical spine computed tomography reports to determine fracture rates in patients ≥ 65, symptomatic or not, who did and did not have a dangerous mechanism. Of those ≥ 65 years old, 240/13925 (1.

Signals are an indicator of strong interest that an applicant can transmit to a limited number of programs. This study assessed the impact of program signaling on interview invitations, how applicants strategically used signals based on their application's competitiveness, and applicants' attitudes toward the current signaling system.

Hypoperfusion intensity ratio has been previously validated as an indirect noninvasive pretreatment imaging biomarker of CS. In addition to imaging, derangements in admission laboratory findings can also influence outcomes in patients with AIS-LVO.

Purpose: The purpose of this study is to conduct a systematic review and meta-analysis on the diagnostic performance of ASL MRI in patients with FTD and compare it with that of [F]-FDG-PET.
Data Sources: A systematic search of PubMed, Scopus, and Embase was conducted until March 13, 2024.
Purpose: Radiology faculty across various specialties have been reported to receive an average of 20.7 invitations to submit manuscripts to bogus journals and 4.1 invitations to speak at unsuitable events over a two-week span.

The aim of this study was to collect experiences related to discrimination among US radiology residents, including type and source, as well as the residents' perception on lectures about discrimination and harassment. We also explored the barriers to reporting, and suggested strategies to overcome them.

Modified Thrombolysis in Cerebral Infarction (mTICI) grades of 2b, 2c, and 3 are all considered successful reperfusion; however, recent studies have shown achieving mTICI 2c/3 leads to better outcomes than mTICI 2b. This study aims to investigate whether any baseline preprocedural or periprocedural parameters are predictive of achieving mTICI 2c/3 in successfully recanalized LVO patients.

In this regard, this study aimed to elucidate the relation between hypothalamic-pituitary adrenal-axis (HPA-axis), toll-like receptors (TLRs), as well as M1/M2 macrophage ratio and pre-atherosclerotic changes in social isolation stress (SIS) in mice. We used small interfering RNA against the glucocorticoid receptor (GR) to evaluate the relation between HPA-axis and TLRs.

In the current study, we evaluated the role of opioid receptors (OPRs) agonists and antagonists in pro-conversant effects of SIS and the common pathway between delta-opioid receptors (DORs) and nitric oxide (NO) in stress-induced seizure. For reaching to this goal, we used pentylenetetrazol (PTZ) model of clonic-seizure to measure seizure threshold and administrated selective and non-selective OPRs agonists and antagonists in both social condition (SC) and isolated condition (IC) animals.
