Identification of RHD allelic variants discovered by atypical typing results on the NEO/Echo platforms

express an RHD allelic variant should be transfused with D– RBCs and, if pregnant, should be given Rh immune globulin (RhIG). To assess if an automated direct agglutination platform could be used to detect D+ patients at risk of forming anti-D, we evaluated the likelihood that decreased reactivity (either indeterminate [?] or 1+) of D typing by MDA on automated analyzers (Galileo Echo [Echo] or Galileo NEO [NEO]; Immucor, Norcross, GA) can reliably predict the necessity of RHD genotyping in WOCBP

Intra-rater and inter-rater reliability of the process of obtaining cross-sectional area and echo intensity measurements of muscles from ultrasound images

Introduction More and more studies rely on ultrasonography (US) to measure muscle quality and size due to the imaging being a noninvasive and inexpensive procedure easily available to clinicians(1). Specifically, cross-sectional area (CSA) and echo intensity (EI) of skeletal muscles obtained with the use of ultrasound imaging provide crucial information regarding muscle composition and quality(2). CSA is a measurement of how large the muscle is, while EI is an index of muscle quality obtained

Performance characteristics of two automated solid-phase red cell adherence systems for pretransfusion antibody screening:  a cautionary tale

Our institution has implemented two instruments, the Galileo and the Echo, that use different solid-phase red cell adherence assays for antibody screening in pretransfusion compatibility testing. During the initial implementation of these two instruments, we noticed very different problems: falsely positive results on the Galileo, and falsely negative results and lack of reproducibility on the Echo. Comparison of falsely positive antibody screen results from approximately equivalent numbers of

Stress echocardiography. Part II: Stress echocardiography in conditions other than coronary heart disease

Introduction Stress echocardiography (stress echo, SE), with use of both old and new ultrasonographic cardiac function imaging techniques, has nowadays become a widely available, safe and inexpensive diagnostic method. Cardiac stress, such as exercise or an inotropic agent, allows for dynamic assessment of a wide array of ventricles, heart valves and pulmonary circulation functional parameters. The registration of dynamic cardiac response provides completely new insight important from both

Stress echocardiography. Part I: Stress echocardiography in coronary heart disease

Introduction Stress echocardiography (stress echo, SE) is a method in which various stimuli are used to elicit myocardial contractility or provoke cardiac ischemia with simultaneous echocardiographic recording of left ventricular function and valvular flow, if needed(1–7). SE is used for the diagnosis of coronary heart disease and valvular heart defects. The stressors used include physical exercise, pharmacological agents (dobutamine, vasodilators) and pacing stress, most often with the use of

Our site performed a comparative analysis of the ORTHO VISION® (Ortho Clinical Diagnostics, Raritan, NJ) and the Echo® (Immucor, Norcross, GA) blood bank analyzers, using the TAT and PT of standard blood bank tests as the outcome metrics. Tests were run in various combinations to reflect the standard workflow of a busy hospital transfusion service and under routine and immediate or STAT conditions. We also compared manual versus automated processing TATs for a variety of pre

The usefulness of high-frequency ultrasonography in the preoperative evaluation of vulvar cancer – a case series

referred to our center at an advanced stage of the disease. Thirdly, HFUS is a mechanical probe, allowing only a gray scale assessment. In our opinion, additional options like Doppler ultrasound, micro-flow imaging, elastography would bring useful information about vulvar cancer. Conclusion HFUS seems a promising tool for the preoperative assessment of BCC and SCC. High-frequency probes can provide some important information, such as morphology, margins, and internal echo, contributing to the choice

highlighted. The most common artifacts of the musculoskeletal system have been described, including those that diagnostically helpful, such as the presence of echo enhancement deep to a fluid-filled structure, or an acoustic shadow behind a calcification. The presence of acoustic shadow in the context of lesions of a different type has also been discussed. The common anisotropy-related artifacts, frequently leading to diagnosis of a pathological condition where none is present, have been elaborated on

WAVLET-BASED ACTIVE SENSING FOR HEALTH MONITORING OF PLATE STRUCTURES USING BASELINE FREE ULTRASONIC GUIDED WAVE SIGNALS

in an effort to tune an appropriate guided wave mode. A five cycle Hanning pulse is transmitted, and the pulse-echo data recorded at the receivers is processed using two novel algorithms, namely damage index 1 (DI1) and damage index 2 (DI2), based on wavelet transformation to identify defects in the form of cracks and loose rivet holes, which are located both near and far away from the array. In both cases, damage index (DI) maps are generated for identification of defects in a particular

Anomalous origin of the right coronary artery from the main pulmonary artery treated surgically in a 6-week-old infant. A case report and review of the literature

, cardiac ECHO showed abnormal origin of the right coronary artery from the trunk of the pulmonary artery. The child was deemed eligible for surgical treatment of the defect. The surgical translocation of the ostium of the right coronary artery to the aorta was done with success, and the child was discharged on the 14th day of hospitalization.ConclusionThe present case report demonstrates that careful examination of the child with precise echocardiographic examination makes it possible to establish an

Those temperatures near the friction surface are quantitatively determined by an effective method consisting of ultrasonic pulseecho measurements and a finite difference calculation for estimating a one-dimensional temperature distribution along the direction of ultrasound propagation. The advantage of the method is that no boundary condition at the friction surface is needed. To demonstrate the practical feasibility of the method, the ultrasonic pulse echo measurements at

The hepatic and right renal ROIs were selected at the same depth along the focusing area near the center of the image to avoid image distortion effects and beam attenuation The sonographic HR ratio was calculated by dividing the mean echo intensity of the pixels within the selected hepatic ROI by those within the selected ROIs of the right renal cortex
