Diagnostic accuracy and image quality evaluation of ultrashort echo time MRI in the lungs. [PDF]

Medicine (Baltimore)
This study evaluates the diagnostic accuracy of ultrashort echo time (UTE)-MRI for detecting pulmonary nodules and image quality. A total of 46 patients at our hospital underwent unenhanced computed tomography (CT) and UTE-MRI.

Association Between T₂^* Relaxation Times Derived From Ultrashort Echo Time MRI and Symptoms During Exercise Therapy for Patellar Tendinopathy: A Large Prospective Study. [PDF]

J Magn Reson Imaging, 2021
Exercise therapy is considered preferential treatment for patellar tendinopathy (PT). However, there is conflicting evidence for structural patellar tendon adaptation in response to exercise therapy and its association with symptoms is weak.

Quantitative Evaluation of Subglottic Stenosis Using Ultrashort Echo Time MRI in a Rabbit Model. [PDF]

Laryngoscope, 2021
To assess the ability of ultra‐short echo time (UTE)‐MRI to detect subglottic stenosis (SGS) and evaluate response to balloon dilation. To correlate measurements from UTE‐MRI with endotracheal‐tube (ETT)‐sizing and to investigate whether SGS causes ...

Performance of free-breathing contrast-enhanced and unenhanced stack-of-spirals ultrashort echo time MRI for lung follow-up in patients with malignancies at 1.5T. [PDF]

Quant Imaging Med Surg
Background Stack-of-spirals ultrashort echo time (spiral-UTE) has been reported to be feasible for lung imaging; however, the performance of free-breathing contrast-enhanced and unenhanced spiral-UTE (UTEe and UTEu) is still unknown.
