Investigation of intravoxel incoherent motion tensor imaging for the characterization of the in vivo human heart

Abstract: To investigate intravoxel incoherent motion (IVIM) tensor imaging of the in vivo human heart and elucidate whether the estimation of IVIM tensors is affected by the complexity of pseudo-diffusion components in myocardium. Methods: The cardiac IVIM data of 10 healthy subjects were acquired using a diffusion weighted spin-echo echo-planar imaging sequence along 6 gradient directions with 10 b values (0~400 s/mm 2). The IVIM data of left ventricle myocardium were fitted to the IVIM tensor model. The complexity of… Show more

“…The signal averaging approach based on multiple acquisitions was employed to further enhance the quality of DW images. These strategies enabled us to obtain comparable SNRs to those reported in the literature 19,20 . However, the SNR of the inferior segment was relatively poor.…”

“…However, the SNR of the inferior segment was relatively poor. This is mainly due to the influence of gastric peristalsis 19 . In addition, the inferior segment is further away from the receiving coil than the other three segments and prone to off‐resonance dephasing due to the vicinity of the posterior vein 19 …”

“…This increased scanning time. However, for thoracic and abdominal DWI, multiple repetitions are commonly employed to reduce cardiac and respiratory motion artifacts 27–30 . In addition, it can be noted that only SD avg ( b ) at b = 0–10 seconds/mm 2 were taken in the calculation of λ values.…”

“…However, for thoracic and abdominal DWI, multiple repetitions are commonly employed to reduce cardiac and respiratory motion artifacts. [27][28][29][30] In addition, it can be noted that only SD avg (b) at b = 0-10 seconds/ mm 2 were taken in the calculation of λ values. The reason is that the contribution of f vfast e ÀbD vfast to DW signal attenuation is approximately zero at relatively high b-values.…”
