From Breath‐Hold to Free‐Breathing: Possibilities in High‐Resolution Quantitative Susceptibility Mapping (QSM) of the Kidney With Respiratory Gating

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aimed to assess the feasibility of QSM in the human kidney during free‐breathing using respiratory gating for motion compensation. Methods Renal imaging of 15 healthy volunteers was performed using an axial multi‐echo GRE sequence on a 3 T MRI scanner.

Independent Component Analysis for Non‐Contrast‐Enhanced Free‐Breathing Pulmonary Ventilation and Perfusion MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To introduce a robust approach for non‐contrast‐enhanced free‐breathing functional lung MRI based on independent component analysis (ICA), addressing key limitations of standard methods such as sensitivity to irregular breathing or irregular heartbeat.

Emergencies in Amyotrophic Lateral Sclerosis

Muscle &Nerve, EarlyView.
ABSTRACT Emergencies are frequent in people living with amyotrophic lateral sclerosis (pALS), especially as the disease progresses, and can necessitate urgent evaluation and intervention. Progressive weakness in ALS inevitably increases fall risk, making discussion of fall prevention strategies integral to caring for pALS.

Efficacy of Exhalation Delivery System With Fluticasone in Chronic Rhinosinusitis With Versus Without Polyps

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective To evaluate whether treatment responses to the exhalation delivery system with fluticasone (EDS‐FLU; XHANCE®) differ between patients with CRS with nasal polyps (CRSwNP) and patients without nasal polyps (CRSsNP). Study Design Post hoc analysis of the ReOpen clinical trials conducted between November 2018 and November 2021 for a 24 ...

Association of Nasal Anatomy, Airflow, and Surgery With Olfactory Outcomes: A State‐of‐the‐Art Review

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Olfactory function is influenced by nasal airflow dynamics and anatomical variations within the nasal cavity. This narrative review evaluates how nasal anatomy and airflow relate to olfactory outcomes, with a particular focus on olfactory changes following functional nasal surgery. Data Sources PubMed.
