Abstract Background Intrauterine growth restriction (IUGR) is a common diagnosis in obstetrics and carries an increased risk of perinatal mortality morbidity. Identification IUGR crucial because proper evaluation management can result favourable outcome. Cardiovascular dysfunction remodelling central feature IUGR. The aim the study was to use left modified myocardial performance index (MPI), as...
OBJECTIVE Cardiac complications are the major cause of morbidity and mortality in beta-thalassemia major. The aim of the study was to evaluate right (RV) and left (LV) ventricular systolic and diastolic functions using myocardial performance index in young, asymptomatic children suffering from thalassemia major, for early detection of cardiac function impairment, preventing further cardiac dama...
a discrete mibi avid lung lesion was found in cinematic views of myocardial perfusion imaging (mpi) of a 59 year-old woman. interestingly, the abnormal uptake in the lung was detectable only in the rest phase images and not in the images acquired in the stress phase. mpi was performed for pre-operation cardiac risk assessment before correction surgery for spinal canal stenosis. she had no past...
Deep learning has become a recent explosion in our everyday lives. Being one of the leading machine tools among various tools, deep contributes lot to image analysis and vision computer. This tool is considered enormous for analysis, especially detecting fetal cardiac abnormalities parallel computing environment. Screening congenital disease (CCD) challenging achieving accuracy terms diagnoses ...
iabetes mellitus (DM) is a major risk factor among typical coronary risk factors that must be considered in the primary and secondary prevention of coronary artery disease (CAD).1–3 The prognosis of diabetic patients without known CAD is reportedly similar to those with previous myocardial infarction.4,5 The diagnostic limitation for CAD in this high-risk group is that clinical symptoms are aty...
BACKGROUND Insulin resistance (IR) assessed by the Homeostatic Model Assessment (HOMA) index in the acute phase of myocardial infarction in non-diabetic patients was recently established as an independent predictor of intrahospital mortality. In this study we postulated that acute IR is a dynamic phenomenon associated with the development of myocardial and microvascular injury and larger final ...
Introduction: The main purpose of this study was to compare transient ischemic dilation (TID) ratios in SPECT-low dose CT and SPECT Myocardial Perfusion Imaging (MPI) by application of different quantitative programs and quantify the possible shift in the upper normal limits of TID ratio in the SPECT-CT MPI. Methods: 149 Patients with low pre-test probability for coronary artery disease (CAD),...
UNLABELLED The aim of this study was to determine and localize culprit lesion by myocardial perfusion imaging (MPI) in cases of angiographically detected coronary narrowing >or= 75% of at least one coronary artery. MATERIAL AND METHODS One hundred and thirty-two (132) patients with angiographically detected significant coronary narrowing (>or= 75% luminal stenosis of at least one major corona...
BACKGROUND It remains unclear whether myocardial contrast echocardiography (MCE) is as accurate as myocardial perfusion imaging with technetium-99m sestamibi (MPI) for the diagnosis of acute coronary syndrome (ACS). We sought to directly compare the diagnostic accuracy of MCE with resting MPI in a head-to-head fashion. METHODS We prospectively enrolled 98 consecutive patients (mean age; 59+/-...
OBJECTIVE The present study aims to study the relationship between tissue Doppler echocardiography (TDE) indices of right ventricle and exercise capacity in patients after total correction for tetralogy of Fallot (ToF). METHODS This cross-sectional observational study included 20 patients, after undergoing total correction procedure for ToF diagnosed with mild/moderate pulmonary regurgitation...
