Needs Assessment Of Pediatric Radiological Equipment And Cross-Cultural Investigation Into Parental Empowerment In Pediatric Radiology Program Development In The Kingdom Of Bhutan, Danielle Canter

GW Research Days 2016 - 2020

Background:

Bhutan is a magnificent mountainous country hugged by India to the east and west and by China to the North and South. This peaceful nestled country faces challenges in combating non-communicable diseases due to the lack of radiological equipment necessary for early diagnosis. Prior to implementation of these medical devices, it is imperative to investigate the cultural attitudes, beliefs, and infrastructure, to ensure successful integration. Bhutan is beginning to implement a pediatric radiology program for the nation with the assistance of ABAH Foundation and RAD-AID International, both of whom partnered with graduate students at George Washington University School of …

Bssfp Elliptical Signal Model With Grappa Parallel Imaging, Grayson Tarbox, Joseph Valentine, Meredith Taylor, Neal Bangerter

Biomedical Engineering Western Regional Conference

In magnetic resonance imaging, balanced steady-state free precession acquisition using the elliptical signal model geometrical solution can be combined with a GRAPPA parallel imaging reconstruction that preserves phase information to shorten scan times.

Difference Image Ultra-Short Echo Time T2* Mapping Using A 3d Cones Trajectory, Amin Nazaran, Grayson Tarbox, Randy Hartley, Neal Bangerter

Biomedical Engineering Western Regional Conference

This study introduces a methodology for detecting subtle variations in tissues with very rapid T2* decay through a difference image ultra-short T2* mapping technique using a 3D cones k-space trajectory. The new method is demonstrated in both a normal and surgically repaired Achilles tendon. The resulting UTE images are differenced and T2* values were calculated using a mono-exponential least squares fit on a voxel by voxel basis. The ultrashort T2* maps yield very consistent short T2* values in healthy tendon of 0.3-0.5 ms, while notable variations and elevations of T2* values are observed in surgically repaired tendon.
