“…The introduction of fast sequences, parallel imaging and iterative reconstruction methods are shifting the attention of the community to cardiac MRI, especially due to no dose, when multiple acquisitions are needed. In addition to that, new acquisition and post-processing techniques hold the potential to provide information about flow [23], ischemic heart disease [24] functional information as well as morphological information of heart.…”

“…it also compares favourably with other non-invasive methods [4][5][6][7][8]. New sequences, advances in hardware, and post-processing are constantly being developed and require substantial preclinical and translational research before making their way into clinical practice [9]. We have recently introduced an isolated blood perfused heart model to facilitate this process [10].…”

Abstract:Purpose: An isolated perfused pig heart model has recently been proposed for the development of novel methods in standard clinical magnetic resonance (MR) scanners. The original set-up required the electrical system to be within the safe part of the MR-room, which introduced significant background noise. The purpose of the current work was to refine the system to overcome this limitation so that all electrical parts are completely outside the scanner room. Methods: four pig hearts were explanted under terminal anaesthesia from large white cross landrace pigs. All hearts underwent cardiovascular magnetic resonance (CMR) scanning in the MR part of a novel combined 3T MR and x-ray fluoroscopy (XMR) suite. CMR scanning included real-time k-t SENSE functional imaging, k-t SENSE accelerated perfusion imaging and late gadolinium enhancement imaging. interference with image quality was assessed by spurious echo imaging and compared to noise levels acquired while operating the electrical parts within the scanner room. Results: imaging was performed successfully in all hearts. The system proved suitable for isolated heart perfusion in a novel 3T XMR suite. No significant additional noise was introduced into the scanner room by our set-up. Conclusions:We have substantially improved a previous version of an isolated perfused pig heart model and made it applicable for MR imaging in a state of the art clinical 3T XMR imaging suite. The use of this system should aid novel CMR sequence development and translation into clinical practice.

“…Magnetic resonance imaging (MRI) allows morphological characterization of heart structures with precision. For the past decade, there has been a great deal of efforts focused on automatic cardiac segmentation [5,1,2], however, less attention has been paid to automatic and fast planning for cardiac MRI acquisition [7,8,4,6], which still remains challenging in clinical practice.…”

“…Danilouchkine et al [4] quantitatively evaluated the difference of clinical meansurements derived from acquisitions between manual and automatic planning on 10 healthy volunteers, concluding that automated CMR planning methods could provide accurate measurements of LV dimensions in normal subjects. In addition to the short-axis stack, long-axis images also provides clinical values, such as through-plane motion analysis [2]. Jackson et al [6] proposed a semiautomatic approach for planning short-axis stack, and two long-axis views, i.e., HLA (4-chamber view) and VLA (2-chamber view).…”

Abstract. Conventional cardiac MRI acquisition involves a multi-step approach, requiring a few double-oblique localizers in order to locate the heart and prescribe long-and short-axis views of the heart. This approach is operator-dependent and time-consuming. We propose a new approach to automating and accelerating the acquisition process to improve the clinical workflow. We capture a highly accelerated static 3D full-chest volume through parallel imaging within one breath-hold. The left ventricle is localized and segmented, including left ventricle outflow tract. A number of cardiac landmarks are then detected to anchor the cardiac chambers and calculate standard 2-, 3-, and 4-chamber long-axis views along with a short-axis stack. Learning-based algorithms are applied to anatomy segmentation and anchor detection. The proposed algorithm is evaluated on 173 localizer acquisitions. The entire view planning is fully automatic and takes less than 10 seconds in our experiments.
