Detecting small pulmonary nodules with spiral ultrashort echo time sequences in 1.5 T MRI

Magnetic Resonance Materials in Physics, Biology and Medicine, 2020
This study investigated ultrashort echo time (UTE) sequences in 1.5 T magnetic resonance imaging (MRI) for small lung nodule detection.A total of 120 patients with 165 small lung nodules before video-associated thoracoscopic resection were enrolled. MRI sequences included conventional volumetric interpolated breath-hold examination (VIBE, scan time 16 ...

Ultrashort Echo Time MRI for Pediatric Patients with Craniofacial Abnormalities

ISMRM Annual Meeting
Motivation: Ionizing radiation risk from CT remains a concern for pediatric patients with craniofacial abnormalities. Goal(s): Use high-resolution bone-selective MRI for cranial bone imaging and evaluate feasibility in pediatric patients. Approach: We quantitatively assessed a new echo-subtraction UTE sequence against clinical CT and another well-known

Comparison of ultrashort echo time sequences for MRI of an ancient mummified human hand

Magnetic Resonance in Medicine, 2015
PurposeTo compare the three different short‐echo time (TE) pulse sequences ultrashort echo time (UTE), point‐wise encoding time reduction with radial acquisition (PETRA), and single point imaging (SPI) for MRI of ancient remains.MethodsMRI of mummies is challenging due to the extremely low water content and the very short transverse relaxation times T2*

Quantifying Lung Water Density with Ultrashort Echo Time Yarn-Ball MRI

2020
Pulmonary edema (PE) involves an excess of extravascular lung water (EVLW) due to an imbalance in fluid filtration which results in hypoxia and respiratory distress. Cardiogenic pulmonary edema is a primary clinical feature and therapeutic target in acute heart failure.

Quantitative Ultrashort Echo‐Time MRI to Assess In Vivo Rotator Cuff Tendon Quality

Journal of Orthopaedic Research
Rotator cuff tears are a common source of pain and disability. Surgical treatment outcomes can be influenced by tendon quality, but conventional MRI does not allow for objective assessment of tendon degeneration.

Osteochondral Abnormalities on Three-Dimensional Ultrashort Echo Time MRI Scans Are Associated with Knee Cartilage Degradation.

Radiology
Background The calcified cartilage layer and subchondral bone plate (SBP) contribute to osteoarthritis development. Three-dimensional (3D) ultrashort echo-time (UTE) MRI can help to evaluate calcified cartilage and SBP in various stages of cartilage ...
