ABSTRACT Purpose This study evaluates the accuracy and reliability of off-line volume measurement using virtual organ computer-aided analysis (VOCALTM) and two-dimensional (2D) ultrasound by novices. Methods Thirty medical students, 15 sonographers and three experts were recruited to measure a liver, a gestational sac and a breast cancer lesion using 2D ultrasound and threedimensional (3D) VOCALTM method. The VOCALTM measurements produced by the experts were used as the gold standard for comparison. Accuracy and reliability were assessed by analysis of variance followed by a mean separation procedure. Results The t-test revealed with statistical significance that in measuring the liver, students outperformed sonographers regardless of 2D or VOCALTM methods; also, VOCALTM generated more accurate measurements than 2D ultrasound in both groups. In regards to the gestational sac, students continued to perform well with both 2D and VOCALTM while the sonographers were accurate by using VOCALTM only. Both groups of novices were not accurate with measuring the breast lesion. VOCALTM increased the novices’ interobserver reliability but not intraobserver reliability. Conclusion Students and sonographers can measure regularly shaped structures, such as the gestational sac accurately and reliably using VOCALTM. VOCALTM increased interobserver reliability in all groups of operators. How to cite this article Nguyen TQ, Flores M, Ortiz M, Lee S, Mulla ZD, Plavsic SK.

This paper describes morphological and cytochemistry changes of endomyocardial biopsy in 94 patients. The samples of myoicardium were taken from 32 patients with dilated cardiomyopathy, and sdudied with light and electron microscop. The cytochemical studies in some of these patients were performed at histological and ultrastructure level. This paper also reported the result of myocardial biopsy in 33 patients with serious dysrythmia.The result of this controlled study indicates that morphological assessment in both cardiomyopathy and congenital or rheumatic heart diseases showed no special changes. In patients of dilated cardiomyopathy, the decreased activity of myosin ATPase was secondary to cardial failure. The change of succinate dehydrogenase (SDHase) was not significant with light microscopy. But ultrastructural localization of SDHase activity is valuable. Its activity was found to be localized in endomembrane and ridge of the mitochondria, the activity of this enzyme was decrease, normal, or increase. SDHase activity was more intense in cardial myocytes well-functioning, or ultrastructurally well preserved hearts.
