Gronman M, Tarkia M, Stark C, Vahasilta T, Kiviniemi T, Lubberink M, et al.
J Nucl Cardiol . 2019 Jul; 28(4):1271-1280. PMID: 31317328
Background: Assessment of myocardial viability is often needed in patients with chest pain and reduced ejection fraction. We evaluated the performance of reduced resting MBF, perfusable tissue fraction (PTF), and...

Radiat Prot Dosimetry . 2019 Apr; 185(4):483-493. PMID: 30989216
The amount of interventional procedures such as percutaneous coronary intervention (PCI), transcatheter aortic valve implantation (TAVI), pacemaker implantation (PI) and ablations has increased within the previous decade. Simultaneously, novel fluoroscopy...

Ultrasound Med Biol . 2018 Nov; 45(2):568-578. PMID: 30467033
We evaluated the relationships between regional myocardial strain measured by speckle tracking echocardiography and viability, fibrosis, hypertrophy and oxygen consumption in the infarcted or remote myocardium in a pig model...

Jafari Tadi M, Teuho J, Lehtonen E, Saraste A, Pankaala M, Koivisto T, et al.
Phys Med Biol . 2017 Sep; 62(20):8080-8101. PMID: 28880843
Positron emission tomography (PET) is a non-invasive imaging technique which may be considered as the state of art for the examination of cardiac inflammation due to atherosclerosis. A fundamental limitation...

Jafari Tadi M, Lehtonen E, Saraste A, Tuominen J, Koskinen J, Teras M, et al.
Sci Rep . 2017 Jul; 7(1):6823. PMID: 28754888
Gyrocardiography (GCG) is a new non-invasive technique for assessing heart motions by using a sensor of angular motion - gyroscope - attached to the skin of the chest. In this...

J Nucl Med . 2017 Mar; 58(10):1691-1698. PMID: 28336781
In PET, corrections for photon scatter and attenuation are essential for visual and quantitative consistency. MR attenuation correction (MRAC) is generally conducted by image segmentation and assignment of discrete attenuation...

Annu Int Conf IEEE Eng Med Biol Soc . 2017 Mar; 2016:2034-2037. PMID: 28268730
The pumping action of the heart is performed by contraction of the myocardium fibers. We present a non-invasive technique named gyrocardiography (GCG) that comprises a sensor of angular motion, gyroscope,...

Cardiovasc Ultrasound . 2017 Jan; 15(1):1. PMID: 28069008
Background: We evaluated echocardiographic area-length methods to measure left ventricle (LV) volumes and ejection fraction (EF) in parasternal short axis views in comparison with cardiac computed tomography (CT) in pigs...

Jafari Tadi M, Lehtonen E, Hurnanen T, Koskinen J, Eriksson J, Pankaala M, et al.
Physiol Meas . 2016 Sep; 37(11):1885-1909. PMID: 27681033
Heart rate monitoring helps in assessing the functionality and condition of the cardiovascular system. We present a new real-time applicable approach for estimating beat-to-beat time intervals and heart rate in...
