Diffusion weighted imaging in cystic fibrosis disease: beyond morphological imaging [PDF]

, 2016
To explore the feasibility of diffusion-weighted imaging (DWI) to assess inflammatory lung changes in patients with Cystic Fibrosis (CF) METHODS: CF patients referred for their annual check-up had spirometry, chest-CT and MRI on the same day.

Ultrashort Echo Time Magnetic Resonance Imaging of the Lung Using a High-Relaxivity T Blood-Pool Contrast Agent

Molecular Imaging, 2014
The lung remains one of the most challenging organs to image using magnetic resonance imaging (MRI) due to intrinsic rapid signal decay. However, unlike conventional modalities such as computed tomography, MRI does not involve radiation and can provide ...

Detection of solid and subsolid pulmonary nodules with lung MRI: performance of UTE, T1 gradient-echo, and single-shot T2 fast spin echo

Cancer Imaging, 2023
Background Although MRI is a radiation-free imaging modality, it has historically been limited in lung imaging due to inherent technical restrictions.

Ultrashort Echo Time and Fast Field Echo Imaging for Spine Bone Imaging with Application in Spondylolysis Evaluation

Computation
Isthmic spondylolysis is characterized by a stress injury to the pars interarticularis bones of the lumbar spines and is often missed by conventional magnetic resonance imaging (MRI), necessitating a computed tomography (CT) for accurate diagnosis.

Optical resonance imaging: An optical analog to MRI with sub-diffraction-limited capabilities [PDF]

, 2016
We propose here optical resonance imaging (ORI), a direct optical analog to magnetic resonance imaging (MRI). The proposed pulse sequence for ORI maps space to time and recovers an image from a heterodyne-detected third-order nonlinear photon echo ...
