Multi-ethnic evaluation of fully automatic planning assist system for cardiac magnetic resonance imaging.

Background We have been developing an automatic planning assist system for coach adjustment, local shimming scan plan, axial multi slice scan plan for slice-alignment, and whole-heart MR imaging plan (motion probes and an axial slab of main scan) [1,2]. However, the previous reposts of the system evaluated only Japanese patient’s and healthy volunteer’s datasets. The purpose of this study is to evaluate the accuracy for multi-ethnic datasets based on the inter-observer error in manual annotation.

Automatic 14-plane slice-alignment method for ventricular and valvular analysis in cardiac magnetic resonance imaging

Background Cardiac MRI examinations for valvular heart diseases have recently been a focus of attention [1]. However, the slice-alignment settings for valvular heart diseases are complex, difficult, and time-consuming operations. The purpose of this study is to develop an advanced automatic slice-alignment method that simultaneously detects the six left-ventricular planes (vertical long-axis, horizontal long-axis, short-axis, 4-chamber, 2-chamber, and 3-chamber views), the four right-ventricular planes (short-axis, 4-chamber, 2-chamber, and 3-chamber views), and also the four cardiac valvular planes (LVOT, RVOT, aortic valve, and pulmonary valve views) by extension of a previous work [2]. “’How I do’ CMR in valvular heart disease”, http://www.scmr.org.
