Dynamic oxygen-enhanced MRI in patients with pulmonary arterial hypertension
Introduction: Oxygen-enhanced MRI (O2-MRI) of the lung is based on the T1-shortening effect of oxygen (O2) inhalation and provides combined information about pulmonary ventilation, perfusion, and diffusion [1–9]. Dynamic O2-MRI acquires (in each pixel) the signal time course influenced by the alternating administration of room air and O2. By fitting a model function (pixelwise) to the acquired ...
متن کاملQuantitative and O2 Enhanced MRI of the Pathologic Lung: Findings in Emphysema, Fibrosis, and Cystic Fibrosis
PURPOSE beyond the pure morphological visual representation, MR imaging offers the possibility to quantify parameters in the healthy, as well as, in pathologic lung parenchyma. Gas exchange is the primary function of the lung and the transport of oxygen plays a key role in pulmonary physiology and pathophysiology. The purpose of this review is to present a short overview of the relaxation mecha...
متن کاملOxygen-enhanced MRI of the Lung
Highlights • Molecular oxygen is paramagnetic and lowers the T1 of nearby protons • Altering the concentration of inhaled O2 changes lung T1-weighted signal • Potential tool for assessing lung function with widespread availability • While usually considered a measure of regional lung ventilation, likely also a function of regional perfusion • Emerging methods address inherently low SNR and impr...
متن کاملDynamic Oxygen-Enhanced MRI of Cerebrospinal Fluid
Oxygen causes an increase in the longitudinal relaxation rate of tissues through its T1-shortening effect owing to its paramagnetic properties. Due to such effects, MRI has been used to study oxygen-related signal intensity changes in various body parts including cerebrospinal fluid (CSF) space. Oxygen enhancement of CSF has been mainly studied using MRI sequences with relatively longer time re...
متن کاملThe Correlation of Brody High Resolution Computed Tomography Scoring System with Clinical Status and Pulmonary Function Test in Patients with Cystic Fibrosis
Background: To reduce the mortality and morbidity rates of cystic fibrosis (CF) patients, and to have an effective clinical management, it is important to monitor the progression of the disease. The aim of this study was to evaluate the progression of lung disease in CF patients by means of assessing the correlation of the CT scoring system with clinical status and pulmonary function test at th...
