“…30–33 Overall, the RT3DE method has improved image quality from the standard 2D images and measured cardiac function with superior diagnostic accuracy in predicting LV mass, systolic function, along with LV and RV volume when compared with 2DE. The results from the regional wall motion abnormalities need to be verified in larger studies.…”

Our review of real-time three-dimensional echocardiography (RT3DE) discusses the diagnostic utility of RT3DE and provides a comparison with two-dimensional echocardiography (2DE) in clinical cardiology. A Pubmed literature search on RT3DE was performed using the following key words: transthoracic, two-dimensional, three-dimensional, real-time, and left ventricular (LV) function. Articles included perspective clinical studies and meta-analyses in the English language, and focused on the role of RT3DE in human subjects. Application of RT3DE includes analysis of the pericardium, right ventricular (RV) and LV cavities, wall motion, valvular disease, great vessels, congenital anomalies, and traumatic injury, such as myocardial contusion. RT3DE, through a transthoracic echocardiography (TTE), allows for increasingly accurate volume and valve motion assessment, estimated LV ejection fraction, and volume measurements. Chamber motion and LV mass approximation have been more accurately evaluated by RT3DE by improved inclusion of the third dimension and quantification of volumetric movement. Moreover, RT3DE was shown to have no statistical significance when comparing the ejection fractions of RT3DE to cardiac magnetic resonance (CMR). Analysis of RT3DE data sets of the LV endocardial exterior allows for the volume to be directly quantified for specific phases of the cardiac cycle, ranging from end systole to end diastole, eliminating error from wall motion abnormalities and asymmetrical left ventricles. RT3DE through TTE measures cardiac function with superior diagnostic accuracy in predicting LV mass, systolic function, along with LV and RV volume when compared with 2DE with comparable results to CMR.

“…Examinations were carried out on the same patient using successively two medical imaging modalities within a short period of time, in order to assume the LV deformations to be reproducible and hence medical comparisons applicable. The first sequence is composed of eight LV surfaces obtained after automatic segmentation from nuclear medicine imaging (NMI), known to be a -gold standard‖ examination for cardiac observation (Figure 10 with a pacemaker (Debrun et al, 1999) and on a mechanical phantom (Debrun et al, 2005), in order to ensure heart beat regularity and volume deformation reproducibility. However, the lack of registration does not allow local comparisons, since the two surface absolute orientations are not known.…”

“…Debrun et al (14) and Lee et al (15) have also developed studies with phantoms for quality control in nuclear medicine. Debrun et al (14) have utilized a dynamic cardiac phantom as a reference in the comparison and validation of volume measurements in gated-SPECT and 4D echocardiography. Lee et al (15) , utilizing a Korean adult voxel phantom, developed a study to calculate the specific absorbed fraction for estimating internal organ dose, and compared their results with data obtained with an adult phantom (Oak Ridge National Laboratory (ORNL), Oak Ridge, USA).…”

OBJETIVO: O objetivo deste trabalho foi verificar a aceitabilidade para a implantação no Brasil de um banco de objetos simuladores nacional, ou bancos regionais, para uso compartilhado desses objetos em atividades de controle de qualidade nos serviços de medicina nuclear. MATERIAIS E MÉTODOS: Foram analisadas as respostas dadas em um questionário que foi enviado a supervisores de radioproteção e físicos médicos de serviços de medicina nuclear do Brasil. Inicialmente, o questionário foi validado por profissionais da cidade de Aracaju, SE, que está localizada no Nordeste. De acordo com as regiões geográficas brasileiras, fizeram parte da amostra investigada: o Nordeste, com respostas de profissionais de 13 serviços de medicina nuclear; o Norte, com 2 profissionais; o Sul, com 7 profissionais; o Sudeste, com 43 profissionais; e o Centro-Oeste, com 2 profissionais. RESULTADOS: Segundo os dados analisados, 82% dos entrevistados consideram que a implantação de um banco de simuladores seria uma alternativa apropriada para o aprimoramento do controle de qualidade em medicina nuclear. O interesse em compartilhar com o banco foi de 87%. CONCLUSÃO: Os resultados mostraram que há motivação para o compartilhamento de objetos simuladores, ou seja, para o uso desses objetos de forma socializada.

Volume measurements in nuclear medicine gated SPECT and 4D echocardiography: validation using a dynamic cardiac phantom

Abstract: The agreement between gated SPECT (after correction) and 4D echocardiography confirmed the relevance of the comparisons. This study was an initial step before conducting clinical trials to compare exhaustively left ventricular volumes obtained with the two modalities.
