Assessment of cardiac wall motion with the ejection fraction image: a comparison with contrast left ventriculography.

Twenty patients with ischemic heart disease were studied with biplane contrast left ventriculography and gated bloob pool scans. An ejection fraction (EF) image was calculated from each gated blood pool scan. The EF image and contrast ventriculograms were divided into three regions and seven segments respectively. The sites of asynergy observed in each study were compared. Segments two, three and six of the contrast ventriculogram corresponded to the anteroseptal and inferoapical regions of the EF image, but it was difficult to differentiate between these segments on the EF image. Segments three and four corresponded to the inferoapical region and segments five and seven corresponded to the posterolateral region. Diffuse asynergy with a low EF (less than 30%) causes a large defect on the EF image. The mean regional EF obtained from the EF image correlated well with the EF calculated from the left ventricular volume curve (n = 50, r = 0.94).

Visualization of hypertrophied papillary muscle mimicking left ventricular mass on gated blood pool and T1-201 myocardial perfusion imaging.

A sixty-year old man with acute myocardial infarction was incidentally found to have a hypertrophied anterolateral papillary muscle (ALPPM) of the left ventricle on gated blood pool (GBP) and T1-201 myocardial perfusion images. Hypertrophy of the ALPPM was visualized as a movable defect in the lateral basal area on GBP imaging throughout the cardiac cycle and on the TI-201 study as a radionuclide accumulating structure, consistent with the defect in the GBP. A combination of these findings may suggest the presence of a hypertrophied papillary muscle of the left ventricle.

Increased localization of 201 Tl-chloride in subacute thyroiditis.

We present two cases of subacute thyroiditis in which increased radionuclide activity in the affected areas was observed on 201 Tl thyroid scintigrams. These were taken to evaluate cold areas on the 99m Tc-pertechnetate thyroid scintigrams. This finding suggests that 201 Tl may be a potentially useful radionuclide in visualizing inflammatory lesions.
