Viability of Oxygen-enhanced Ventilation Imaging of the Lungs Using Ultra-short Echo Time MRI
نویسندگان
چکیده
PURPOSE To assess the viability of oxygen-enhanced ventilation images using ultra-short echo time magnetic resonance imaging (UTE-MRI). METHODS We evaluated the oxygen enhancement of the pulmonary T2*, and pulmonary signals in each TE (0.2, 0.8, 1.4, 2.0 ms) in 21 nonsmokers. RESULTS The oxygen enhancement of pulmonary signals was the most significant (32%) at the 0.2 ms TE, the second in the pulmonary T2* (-18%). CONCLUSIONS Pulmonary images using UTE-MRI are useful for ventilation imaging.

Ventilation/Perfusion MR imaging of the lung using T1-weighted ultra-short echo time (UTE) imaging: animal experiment in a 3 T clinical MRI system
Introduction: Ultra-short TE (UTE) imaging in conjunction with projection acquisition of free induction decay (FID) can reduce TE to less than 100 μs thus minimizing signal decay caused by short transverse relaxation time (T2/T2*). This allows detection of endogenous MR signal of the lung parenchyma compared to a conventional short echo image sequence (1). Using an UTE sequence, we have demonst...
متن کاملLung imaging using oxygen-enhanced MRI in small animals
BACKGROUND Oxygen enhanced magnetic resonance imaging (OE-MRI) is a novel method of assessing regional ventilation and oxygen diffusion from the alveoli into the capillaries of the lung. The paramagnetic nature of oxygen and deoxyhemoglobin in blood shortens the T1 of the oxygenated tissues. MRI can visualize the effect by a signal increase on T1 weighted images acquired with subjects during br...

Background: There are various methods to read out responses of a polymer-gel dosimeter, among which the Magnetic Resonance Imaging (MRI) technique is the most common one. Optimizing imaging protocols can have significant effect on the sensitivity and the dose resolution of polymer gel dosimeters. This study has investigated the effects of the number of echoes (NOE) and the echo time spacing (ES...
متن کاملOxygen-enhanced MR imaging of mice lungs.
Inhaled molecular oxygen has been widely used in humans to evaluate pulmonary ventilation using MRI. MR imaging has recently played a greater role in examining the morphologic and physiologic characteristics of mouse models of lung disease where structural changes are highly correlated to abnormalities in respiratory function. The motivation of this work is to develop oxygen-enhanced MR imaging...
