Automated calculation of gallbladder ejection fraction
European Journal of Nuclear Medicine, 1983We have developed a computer method which by automatically locating the border of the gallbladder in each image and subtracting a varying location-dependent background corresponding to the gallbladder border overcomes the difficulties associated with quantitating gallbladder contraction.

Heart failure (HF) is a significant and increasing global public health problem. In the United States, hospital admissions for a principal diagnosis of HF increased from 399 000 in 1979 to 1 093 000 in 2003. 1 The diagnosis of HF continues to be associated with poor quality of life, high morbidity, and high mortality despite contemporary HF management.

Is heart failure with midrange ejection fraction similar to preserved ejection fraction? In favor
Revista Clínica Española (English Edition), 2017Abstract Basing heart failure (HF) classification on the echocardiographic values of left ventricular ejection fraction (LVEF) has been useful in defining two sub-types of HF:HF with reduced LVEF and HF with preserved LVEF. A new category has recently been defined: HF with midrange LVEF (40–49%).

ESPVR, Ejection Fraction and Heart Failure
Cardiovascular Engineering, 2010The problem of heart failure with preserved ejection fraction (HFpEF) has recently received much attention. In this study we discuss some relations that connect ejection fraction EF to the parameters describing the end-systolic pressure-volume relation (ESPVR).
