Factorial phase imaging: a new concept in the analysis of first-pass cardiac studies

摘要: A method is described which offers an alternative to conventional Fourier phase/amplitude imaging for analysing representative LV cycles obtained from first-pass cardiac studies. The involves applying factor analysis the data and producing functional images of first two loadings after polar transformation. corrects cycle asymmetries produce anomalies in images. For 88 studies provides greater uniformity among normal phase while retaining, or even enhancing, abnormalities. Small differences between amplitude produced by methods do not appear be important.
