Purpose To implement and assess the performance of three‐dimensional (3D) ultra‐short
echo (UTE) time for evaluating lung tissue density changes induced by gravity dependence …

Nonuniform disruption of lung architecture is usually assessed by CT, which carries potential
radiation risk. Here we report our use of a three‐dimensional ultrashort echo time MR …

Background Computed tomography (CT) and spirometry are the current standard methods
for assessing lung anatomy and pulmonary ventilation, respectively. However, CT provides …

Background Imaging of the lung by MRI is challenging due to the intrinsic low proton density
and rapid T2* relaxation. MRI methods providing lung parenchyma and function are in …

Objective To determine the feasibility of using high-resolution volumetric zero echo time
(ZTE) sequence in routine lung magnetic resonance imaging (MRI) and compare free …

Purpose To evaluate lung water density at three different levels of lung inflation in normal
lungs using a fast gradient echo sequence developed for rapid imaging. Materials and …

Purpose To develop and assess a new technique for three‐dimensional (3D) full lung T1
and T2* mapping using a single free breathing scan during a clinically feasible time …

Background To evaluate ultra‐short‐echo‐time (UTE) MRI pulmonary signal‐intensity
measurements and reproducibility in chronic obstructive pulmonary disease (COPD) …

Purpose To measure the and T1 of mouse lung at 7T via anisotropic‐resolution radial
ultrashort echo‐time imaging with ellipsoidal k‐space coverage. Methods Ellipsoidal field‐of …

Purpose To evaluate three-dimensional (3D) ultrashort echo time (UTE) MRI regarding
image quality and suitability for functional image analysis using gradient-echo sequences in …
