“…The correlation coefficient between the global values of these parameters is in agreement with previous similar studies (Kontos et al 2002;Oh et al 1996;Paluszkiewicz et al 2002). The correlation results calculated by the 2D-strain software are similar to the correlation between WMSI and perfusion, a fact which further validates the 2D-strain algorithm.…”

“…However, studies have shown that LVEFs assessed by radionuclide angiography and echocardiography exhibit a high correlation and overall agreement, 41,42 with only a minority of patients having EFs that differed by more than 10%. [42][43][44] The difference in EF between both the techniques shown in this study is therefore more likely to reflect a higher sensitivity of RVG to detect true impairment of cardiac function, rather than a difference in measurement because of different imaging modalities.…”

Serial echocardiography to detect doxorubicin dose-related cardiotoxicity correlates poorly with endomyocardial biopsy-proven cardiotoxicity. To compare radionuclide ventriculography (RVG) and echocardiography for the assessment of left ventricular (LV) function in children with Hodgkin disease (HD) receiving doxorubicin, we studied 39 children with HD before radiotherapy, both early (≤ 2 adriamycin, bleomycin, vinblastine, and dacarbazine cycles) (group A; n=10) and late (≥ 6 adriamycin, bleomycin, vinblastine, and dacarbazine cycles) (group B; n=36) during treatment. Seven children were assessed twice. The patients underwent full clinical assessment, echocardiography, and RVG. In group A, LV ejection fraction (LVEF) was significantly lower when measured by RVG compared with echocardiography (P<0.05). Group B had lower LVEF compared with group A by echocardiography (P=0.09), and by RVG (P=0.000). Paired analysis of children studied early and late showed a significant drop in LVEF by echocardiography (58.7 ± 7.3 vs. 52 ± 52.44%; P=0.04) and RVG (51.4 ± 2.6% vs. 47.2 ± 3.1%; P=0.004). The cumulative dose of doxorubicin inversely correlated with RVG-measured LVEF (r=-0.531; P=0.001). No correlation was found between LVEF measured by RVG and echocardiography (r=0.217; P=0.25). Cardiotoxicity occurred early and at low cumulative doses of doxorubicin in children with HD. RVG was more sensitive than echocardiography in detecting early impairment of LV function. We recommend baseline and serial assessment of LV function by RVG in children with HD receiving doxorubicin.

“…Because modern reperfusion therapies constantly improve and smaller infarcts are more frequently to be expected, this amount may even increase in the future. Furthermore, regional relative tracer inhomogenities resulting from soft tissue attenuation or scatter may compromise the diagnostic accuracy of SPECT imaging (6,7).…”

“…Other SPECT studies in patients with AMI reported comparable rates of undetected infarcts ranging from 11% to 25% (4,6). Because the spatial resolution of SPECT images is about 10 ϫ 10 ϫ 10 mm and comparable with the thickness of the heart wall, non-transmural infarcts are difficult to detect (22).…”
