AI Article Synopsis
- Intracranial abscesses are serious medical emergencies caused by pus buildup in the brain, and delays in diagnosis can lead to severe health issues or death.
- Imaging techniques like computed tomography (CT) and magnetic resonance imaging (MRI) are crucial for diagnosing these abscesses, but their typical appearance can be confused with conditions like necrotic tumors.
- This paper explores recent advancements in CT and MRI technology for detecting brain abscesses, focusing on techniques such as CT perfusion and various MRI sequences.
Article Abstract
Intracranial abscesses are life-threatening medical emergencies with pyogenic debris accumulating in the brain. Delay in the diagnosis can result in significant morbidity and mortality. Computed tomography and magnetic resonance imaging play an important role in the diagnosis of brain abscesses. However, the classic ring-enhancing appearance of an intracranial abscess can be mimicked by several other entities, most notably a necrotic tumor. This paper reviews new advances in CT and MR for imaging patients with suspected brain abscess. The role of computed tomography (CT) perfusion and new magnetic resonance sequences including DWI sequences, ADC map, MR spectroscopy, FLAIR and post-contrast enhanced T1 weighted images will also be discussed.

Background/objectives: Evidence suggests nasal airflow resistance reduces after rapid maxillary expansion (RME). However, the medium-term effects of RME on upper airway (UA) airflow characteristics when normal craniofacial development is considered are still unclear. This retrospective cohort study used computer fluid dynamics (CFD) to evaluate the medium-term changes in the UA airflow (pressure and velocity) after RME in two distinct age-based cohorts.

Introduction: The purpose of this study was to evaluate the association between body composition, overall survival, odds of receiving treatment, and patient-reported outcomes (PROs) in individuals living with metastatic non-small-cell lung cancer (mNSCLC).
Methods: This retrospective analysis was conducted in newly diagnosed patients with mNSCLC who had computed-tomography (CT) scans and completed PRO questionnaires close to metastatic diagnosis date. Cox proportional hazard models and logistic regression evaluated overall survival and odds of receiving treatment, respectively.

Background: Coronary computed tomography angiography (CCTA) is emerging as a valuable tool for noninvasive surveillance of cardiac allograft vasculopathy (CAV) in patients with heart transplant (HTx). We assessed the diagnostic performance of a comprehensive CCTA-based approach compared with the invasive reference, which includes invasive coronary angiography, intravascular ultrasound, and fractional flow reserve, for detecting CAV.
Methods: This was a multicenter prospective study including 37 patients with HTx who underwent CCTA, invasive coronary angiography, intravascular ultrasound, and fractional flow reserve.
