2. 1. Toward increased applicability of ultrasound contrast agents

   Author : Malin Larsson; Lars-Åke Brodin; Anna Bjällmark; Kenneth Caidahl; Jan Engvall; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contrast agent; Contrast-to-tissue-ratio; Echocardiography; Endocardial border; Microbubbles; Multimodal; Phantom; Polymer; Ultrasound; Wall motion score index.; Teknik och hälsa; Technology and Health;

   Abstract : Ultrasound is one of the most widely used modalities in medical imaging because of its high cost-effectiveness, wide availability in hospitals, generation of real-time images, and use of nonionizing radiation. However, the image quality can be insufficient in some patients. READ MORE

4. 2. Quantitative echocardiographic methods for patients with acute coronary syndrome

   Author : Carl Westholm; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Tissue Doppler;

   Abstract : Background: The aim of this thesis was to evaluate two diagnostic and two prognostic quantitative echocardiographic methods for patients with acute coronary syndrome (ACS). Methods:
Velocity tracking (VeT) presents the longitudinal tissue Doppler velocities of the left ventricle (LV) as a bull’s eye plot giving an easy three dimensional understanding of both the global and regional function of the LV in regard to longitudinal velocities, systolic as well as diastolic.

   Abstract : IntroductionPaper I: An Artificial Neural Network (ANN) was constructed to identify ST Elevation Myocardial Infarction (STEMI) and predict the need for Percutaneous Coronary Intervention (PCI). Paper II, III and IV: Studies suggest that O2 therapy may be harmful in STEMI patients. READ MORE

6. 4. Unstable post-infarction ischemia : identification and risk stratification with special emphasis on noninvasive methods

   Author : Miguel Quintana; Karolinska Institutet; Karolinska Institutet; []
   Keywords : myocardial infarction; myocardial ischemia; prognosis; exercise test; stress echocardiogaphy. ambulatoryelectrocardiography; heart rate variability.Stockholm 1996;

   Abstract : Although in-hospital mortality after acute myocardial infarction has decreased, long-term mortality is still high. This study tested the prognostic value of detecting residual myocardial ischemia by different techniques in 74 patients recovering from an acute myocardial infarction. READ MORE

7. 5. Infarct size and myocardial function : A methodological study

   Author : Lene Rosendahl; Jan Engvall; Thor Edvardsen; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : The size of a myocardial infarction (MI) and the concurrent effect on left ventricular (LV) function are essential for decisions regarding patient care and treatment. Images produced with the late gadolinium enhancement (LGE) technique visualize the scar with high spatial resolution. READ MORE
