Task-based optimization of flip angle for fibrosis detection in T1-weighted MRI of liver

Autor: Brand, Jonathan F., Furenlid, Lars R., Altbach, Maria I., Galons, Jean-Philippe, Bhattacharyya, Achyut, Sharma, Puneet, Bhattacharyya, Tulshi, Bilgin, Ali, Martin, Diego R.

Chronic liver disease is a worldwide health problem, and hepatic fibrosis (HF) is one of the hallmarks of the disease. The current reference standard for diagnosing HF is biopsy followed by pathologist examination; however, this is limited by samplin

Volumetric MRI of the lungs during forced expiration

Autor: Berman, Benjamin P., Pandey, Abhishek, Li, Zhitao, Jeffries, Lindsie, Trouard, Theodore P., Oliva, Isabel, Cortopassi, Felipe, Martin, Diego R., Altbach, Maria I., Bilgin, Ali

Purpose: Lung function is typically characterized by spirometer measurements, which do not offer spatially specific information. Imaging during exhalation provides spatial information but is challenging due to large movement over a short time. The pu

A Comparison of Deep Learning Convolution Neural Networks for Liver Segmentation in Radial Turbo Spin Echo Images

Autor: Umapathy, Lavanya, Keerthivasan, Mahesh Bharath, Galons, Jean-Phillipe, Unger, Wyatt, Martin, Diego, Altbach, Maria I, Bilgin, Ali

Motion-robust 2D Radial Turbo Spin Echo (RADTSE) pulse sequence can provide a high-resolution composite image, T2-weighted images at multiple echo times (TEs), and a quantitative T2 map, all from a single k-space acquisition. In this work, we use a d

Report

Quantitative T2 Estimation Using Radial Turbo Spin Echo Imaging

Autor: Keerthivasan, Mahesh B, Bilgin, Ali, Altbach, Maria I

There has been increased interest in the quantitative characterization of tissues based on T2 in abdominal imaging. Techniques based on spin-echo or turbo spin-echo sequences are time consuming because they require multiple acquisitions for obtaining
