The example system includes a Doppler spectrum recorder to record a Doppler spectrum. The example system includes a study type inferrer to infer a study type associated with the Doppler spectrum by: processing the Doppler spectrum using at least one neural network to generate a first probability ...
In this regard we investigated the feasibility of epi-aortic Doppler measurements in order to calculate cardiac output. : Epi-aortic cardiac output measurement was compared with Fick measurements as the gold standard in eight patients with a univentricular circulation after a Fontan-type operation. ...
Doppler ultrasound (DUS), electrocardiogram (ECG) and pulse oximetry (POX) were used for cardiac triggering. DUS peak detection was verified in comparison to ECG. Quantitative analysis of image quality of each gating method was determined by calculating endocardial border sharpness (EBS) and left ...
However, to date, no study with such a large series of patients and a minimum follow-up of 15 years, has attempted to undertake a comprehensive evaluation of cardiac parameters with techniques other than Doppler US, and controlled for drugs other than adriamycin and for the radiation dose ...

Advanced sonographic techniques can be used to study the heart. For example, Doppler ultrasonography can measure blood flow velocity or identify abnormal flow patterns across valves and within heart chambers. M-mode echocardiography also offers an important method for analyzing cardiac dysrhythmias, suspe...
CARDIAC TROPONIN T CONCENTRATIONS MEASURED WITH A HIGH-SENSITIVITY ASSAY INTEGRATE INFORMATION ON REVERSIBLE MYOCARDIAL ISCHEMIA AND LEFT VENTRICULAR MASS IN PATIENTS WITH SUSPECTED STABLE ANGINA PECTORIS: A DOPPLER-CIP SUBSTUDY 来自 学术范 喜欢 0 阅读量: 20 ...
The systolic function and diastolic function was calculated using pulsed-wave Doppler imaging as we previously described [29]. For euthanasia, animals were anesthetized with 5% isoflurane, anaesthesia was confirmed via tail pinch, and then sacrificed by cervical dislocation before cardiac tissue removal....
PURPOSE: To prospectively evaluate the accuracy of contrast material-enhanced cardiac magnetic resonance (MR) imaging for determining impaired coronary flow velocity reserve (CFR) by using Doppler flow measurement as the reference standard. MATERIALS AND METHODS: The study was approved by the institutiona...
