For patients with impaired breath-hold capacity, highly accelerated cardiac cine MRI may be useful. The purpose of this study is to perform functional MR imaging of the whole heart in a single breath-hold using an under-sampled data acquisition in combination with compressed sensing with parallel imaging. The proposed technique is applied for in-vivo functional cardiac imaging of the whole heart in a single breath-hold. Applied compression factors are 4 of ITSC and 2 of SENSE. The whole heart coverage in a single breath-hold using ITSCxSENSE can be used to achieve adequate spatial resolution (1.8 mm × 1.8 mm) and relatively high temporal resolution (31 ms), with good image quality and functional movement. It takes 23s for the reconstruction of single slice CINE images (22 cardiac phases). The ITSCxSENSE may be useful for patients with reduced breath-hold capacity.
