We propose a simple but novel data acquisition technique for whole-heart coronary magnetic resonance angiography (CMRA). In this technique, the breath-hold chasing MRA, data are collected during breath-hold intervals, with the navigation window manually adjusted to the diaphragmatic level. Compared with the conventional free breathing MRA, this method provided 33% reduction of acquisition time and improved visibility of right coronary artery in 18 normal subjects without any additional software or hardware requirements.

Introduction: Thermal ablative therapies (laser, radiofrequency ablation, electrocautery, argon plasma coagulation) are often used during rigid bronchoscopy for the treatment of central airway obstructions (CAO). An airway fire is a feared complication that can occur during endobronchial thermal ablation.

Materials And Methods: This was a single-center, retrospective, observational study.

Breathing Inhibited When Seizures Spread to the Amygdala and upon Amygdala Stimulation.

J Neurosci

July 2015

Molecular Physiology and Biophysics, Neurology, and Interdisciplinary Graduate Program in Neuroscience, University of Iowa, Iowa City, Iowa 52242, Department of Veterans Affairs Medical Center, Iowa City, Iowa 52242.

Unlabelled: Sudden unexpected death in epilepsy (SUDEP) is increasingly recognized as a common and devastating problem. Because impaired breathing is thought to play a critical role in these deaths, we sought to identify forebrain sites underlying seizure-evoked hypoventilation in humans. We took advantage of an extraordinary clinical opportunity to study a research participant with medically intractable epilepsy who had extensive bilateral frontotemporal electrode coverage while breathing was monitored during seizures recorded by intracranial electrodes and mapped by high-resolution brain imaging.

Exercise at depth alters bradycardia and incidence of cardiac anomalies in deep-diving marine mammals.

Nat Commun

Department of Marine Biology, Texas A&M University, 200 Seawolf Parkway, Ocean and Coastal Sciences Building, Galveston, Texas 77554, USA.

Unlike their terrestrial ancestors, marine mammals routinely confront extreme physiological and physical challenges while breath-holding and pursuing prey at depth. To determine how cetaceans and pinnipeds accomplish deep-sea chases, we deployed animal-borne instruments that recorded high-resolution electrocardiograms, behaviour and flipper accelerations of bottlenose dolphins (Tursiops truncatus) and Weddell seals (Leptonychotes weddellii) diving from the surface to >200 m. Here we report that both exercise and depth alter the bradycardia associated with the dive response, with the greatest impacts at depths inducing lung collapse.

Purpose: To investigate the dosimetric impact of using 4D CT and multiphase (helical) CT images for treatment planning target definition and the daily target coverage in hypofractionated stereotactic body radiotherapy (SBRT) of lung cancer.

Materials And Methods: For 10 consecutive patients treated with SBRT, a set of 4D CT images and three sets of multiphase helical CT scans, taken during free-breathing, end-inspiration and end-expiration breath-hold, were obtained. Three separate planning target volumes (PTVs) were created from these image sets.
