DCE-MRI assessment of response to neoadjuvant SABR in early stage breast cancer: Comparisons of single versus three fraction schemes and two different imaging time delays post-SABR.
Matthew Mouawad,Heather Biernaski,Muriel Brackstone,Michael Lock,Michael Lock,Brian Yaremko,Brian Yaremko,Olga Shmuilovich,Olga Shmuilovich,Anat Kornecki,Anat Kornecki,Ilanit Ben Nachum,Ilanit Ben Nachum,Giulio Muscedere,Giulio Muscedere,Kalan Lynn,Kalan Lynn,Frank S. Prato,R. Terry Thompson,R. Terry Thompson,Stewart Gaede,Neil Gelman,Neil Gelman +22 more
TL;DR: Only 1 fraction SABR increased tissue enhancement, suggesting vascular damage, and 2.5 weeks post-SABR seems sufficiently long for tumour response assessment.

Heart Rate-Independent 3D Myocardial Blood Oxygen Level-Dependent MRI at 3.0 T with Simultaneous 13N-Ammonia PET Validation.
Hsin-Jung Yang,Damini Dey,Jane Sykes,John Butler,Heather Biernaski,Michael S. Kovacs,Xiaoming Bi,Behzad Sharif,Ivan Cokic,Richard Tang,Piotr J. Slomka,Frank S. Prato,Rohan Dharmakumar +12 more
TL;DR: This three-dimensional cardiac blood oxygen level-dependent MRI approach overcame key limitations associated with conventional cardiac BOLD MRI by enabling whole-heart coverage within the standard duration of adenosine infusion, and increased the magnitude and reliability of BOLD contrast, which may be performed without requiring breath holds.

Reducing the dose of gadolinium-based contrast agents for DCE-MRI guided SBRT: The effects on inter and intra observer variability for preoperative target volume delineation in early stage breast cancer patients.
Matthew Mouawad,Heather Biernaski,Muriel Brackstone,Michael Lock,Michael Lock,Brian Yaremko,Brian Yaremko,Tracy Sexton,Tracy Sexton,Edward Yu,Edward Yu,Robert Dinniwell,Robert Dinniwell,Kalan Lynn,G. Hajdok,Frank S. Prato,Frank S. Prato,Robert Terry Thompson,Robert Terry Thompson,Neil Gelman,Neil Gelman,Stewart Gaede,Stewart Gaede,Stewart Gaede +23 more
TL;DR: Reducing the dose of contrast agent in a DCE-MRI scan did not significantly alter inter- or intra-observer variability, and these results have prompted the centre to reduce the doses of gadolinium in all patients enrolled in the SIGNAL trial.

Functional CT assessment of extravascular contrast distribution volume and myocardial perfusion in acute myocardial infarction.
Aaron So,Aaron So,Gerald Wisenberg,Patrick Teefy,Andrew Yadegari,Rodrigo Bagur,Jennifer Hadway,Laura Morrison,Anna MacDonald,Dave Gaskin,John Butler,Heather Biernaski,Stephanie Skanes,Stella DohYeoun Park,Ali Islam,Jiang Hsieh,Ting-Yim Lee,Ting-Yim Lee +17 more
TL;DR: This imaging technique can rapidly and simultaneously assess myocardial edema and ischemia through ECDV and MP measurements, and may be useful for delineation of salvageable tissue within at-risk myocardium to guide reperfusion therapy.

TL;DR: In this paper, a reference-based hybrid PET/magnetic resonance imaging (MRI) method that uses functional MRI techniques to calibrate 15O-O2-PET data was proposed.
