Journal ArticleDOI
Improved quantification of small hearts for gated myocardial perfusion imaging
Kenichi Nakajima,Koichi Okuda,Karin Nyström,Jens Richter,David Minarik,Hiroshi Wakabayashi,Shinro Matsuo,Seigo Kinuya,Lars Edenbrandt,Lars Edenbrandt +9 more
TL;DR: The volume-dependent edge correction algorithm was able to effectively reduce the effects on ESV and EF of a small heart and might be applicable to both men and women and to both small and normal-sized hearts.
Journal ArticleDOI
Diagnostic Performance of Artificial Neural Network for Detecting Ischemia in Myocardial Perfusion Imaging
Kenichi Nakajima,Shinro Matsuo,Hiroshi Wakabayashi,Kunihiko Yokoyama,Hisashi Bunko,Koichi Okuda,Seigo Kinuya,Karin Nyström,Lars Edenbrandt +8 more
TL;DR: In this article, an artificial neural network (ANN) was applied in patients with coronary artery disease (CAD) and compared with conventional visual and quantitative methods in myocardial perfusion imaging (MPI).
Journal ArticleDOI
When is reacquisition necessary due to high extra-cardiac uptake in myocardial perfusion scintigraphy?
Allan Johansen,Milan Lomsky,Oke Gerke,Oke Gerke,Lars Edenbrandt,Lars Edenbrandt,Lena Johansson,Gunhild Hansen,Birgitte Toft Jensen,Maria Sallerup Reid,Liselott Nilsson Johansson,Camilla Olofsson,David Minarik,Karin Nyström,Per Wollmer,Elin Trägårdh +15 more
TL;DR: This study indicates that repeat acquisition is useful when the intensity of the extra-cardiac uptake is equal to or higher than the cardiac uptake when there is no separation between theExtra-Cardiac uptake and the inferior cardiac wall of less than one cardiac wall.
Journal ArticleDOI
Area of ischemia assessed by physicians and software packages from myocardial perfusion scintigrams
Lars Edenbrandt,Lars Edenbrandt,Peter Höglund,Sophia Frantz,Philip Hasbak,Allan Johansen,Lena Johansson,A. Kammeier,Oliver Lindner,Milan Lomsky,Shinro Matsuo,Kenichi Nakajima,Karin Nyström,Eva Olsson,Karl Sjöstrand,Sven-Eric Svensson,Hiroshi Wakabayashi,Elin Trägårdh +17 more
TL;DR: There was large variability in the estimated ischemic defect size obtained both from different physicians and from different software packages, and when the physicians were provided with a suggested delineation, the inter-observer variability decreased significantly.
