Fast 3D Cardiac Cine MR Imaging

Abstract

We describe a technique for three‐dimensional cine MR imaging. By using short repetition times (TR) and interleaved slice encoding, volumetric cine data can be acquired throughout the cardiac cycle with a temporal resolution of approximately 80 msec. A T1‐shortening agent is used to produce contrast between blood and myocardium. A comparison between the acquisition times of this and several other two‐dimensional techniques is presented. J. Magn.

Evaluation of global cardiac functional parameters using single-breath-hold three-dimensional cine steady-state free precession MR imaging with two types of speed-up techniques: Comparison with two-dimensional cine imaging

“…In our institution, HCM cases were often introduced to MR examinations because of the usefulness of cardiac MR imaging for the evaluation of myocardial fibrosis and LV myocardial mass in HCM. However, this may not devalue this study, as the previous studies using 3D cine MR imaging techniques have not included HCM cases with high LV ejection fraction [7][8][9][10]. Finally, several imaging parameters, including acceleration factors of SENSE and k-t BLAST and training data points of k-t BLAST, were determined based on the breath-holding time as well as on some previous reports [7][8][9]12,16].…”

“…Compared with 2D cine imaging, three-dimensional (3D) cine MR imaging has several advantages: complete data acquisition during a single-breath-hold and simplifying the cardiac examinations [7][8][9][10]. Because of the short TR, 3D cine cardiac MR imaging using T1-weighted gradient-echo imaging cannot provide sufficient CNR between the myocardium and LV cavity without contrast agents [10].…”

“…Because of the short TR, 3D cine cardiac MR imaging using T1-weighted gradient-echo imaging cannot provide sufficient CNR between the myocardium and LV cavity without contrast agents [10]. When using an SSFP imaging sequence, however, 3D cine cardiac images with sufficient SNR can be acquired [7][8][9].…”

Deep venous thrombosis and consecutive pulmonary embolism as the first sign of an ovarian cancer: MR angiography using an intravascular contrast agent (CLARISCAN)

“…Since the intravascular CM has a relatively long plasma half-life time (Ͼ 45 min), it is suited for many 3D MRA applications (4). Similar CMs have shown promising results for imaging of the abdominal and pulmonary vasculature in animals and humans (7)(8)(9), and CLARISCAN has also proved to be useful for imaging of the heart in humans (10,11). The only known side effect of CLARISCAN is an elevation of serum iron concentration, which is reversible within a few hours.…”

Volumetric assessment of myocardial viability in rats using 3D double contrast enhanced T1 and T2-weighted MRI

“…T1-weighted MR imaging is currently performed both in humans [7][8][9][10] and in animals [11,12] but T2-weighted 3D MR imaging of myocardium or vessels is less common.…”
