چکیده

Fig. 3: High resolution cardiac perfusion imaging in 12 slices using CAIPIRINHA with an effective acceleration factor of Reff = 5. Shown is the pass of the contrast agent through the myocardium in 8 short (left) and 4 long axis slices (right). The slices shown in the upper row were acquired exactly at the same time as the corresponding slices in the bottom row. High Resolution Whole Heart Cardiac Perfusion Imaging Using CAIPIRINHA

Myocardial perfusion imaging using CAIPIRINHA accelerated multi-slice saturation recovery TrueFISP

Introduction: Saturation recovery (SR) prepared TrueFISP sequences are widely in use for myocardial perfusion imaging because of a high intrinsic signal-to-noise ratio (SNR). Since the image acquisition is limited by the heart cycle, a complete coverage of the heart with consecutively acquired slices is difficult. Parallel imaging techniques are required significantly reducing the acquisition t...

Quantification of perfusion defects with high resolution 2D and 3D adenosine stress perfusion 3.0 Tesla CMR

Background Myocardial ischaemic burden is an important marker of outcome in stable ischaemic heart disease with a 10% ischaemic burden suggested as a clinically relevant threshold for revascularisation. Standard CMR stress perfusion imaging utilises 3 short axis slices, each acquired in different phases of the cardiac cycle. Recently proposed 3D myocardial perfusion CMR allows the entire myocar...

High-frame rate four dimensional optoacoustic tomography enables visualization of cardiovascular dynamics and mouse heart perfusion

Functional imaging of mouse models of cardiac health and disease provides a major contribution to our fundamental understanding of the mammalian heart. However, imaging murine hearts presents significant challenges due to their small size and rapid heart rate. Here we demonstrate the feasibility of high-frame-rate, noninvasive optoacoustic imaging of the murine heart. The temporal resolution of...

First-pass myocardial perfusion imaging with whole ventricular coverage using L1-SPIRIT accelerated spiral trajectories

Background First-pass perfusion imaging using cardiac magnetic resonance (CMR) has become clinically applicable as an important tool for diagnosing coronary artery disease. We have recently demonstrated that high quality firstpass images can be acquired with an optimized spiral pulse sequence, but this sequence is only capable of imaging 3 short axis slices of the heart for a maximum heart rate...
