Aqueductal stenosis: demonstration by MR imaging.

A case of nontumorous stenosis of the aqueduct of Sylvius is presented, demonstrating the superiority of sagittal magnetic resonance imaging over other imaging modalities in identifying this disorder.

Adult

Left ventricular thrombus. Detection by ECG synchronized cineangiography.

The detection of a left ventricular mural thrombus, a potentially fatal complication of various heart diseases, is often missed by current radiographic techniques. The findings on ECG synchronized radionuclide cineangiography in a patient with a large thrombus in the left ventricular cavity, confirmed by echocardiography and angiography are reported. This suggests a role for radionuclide cineangiography in the detection of left ventricular mural thrombus.

Coronary Disease

CT diagnosis of renal cyst wall tumor.

Renal cysts are common lesions especially in the older population. Although the occurrence of a tumor within the wall of an otherwise benign cyst is rare, its accurate diagnosis is difficult. We present such a case, diagnosed preoperatively by computed tomography.

Ebstein's anomaly: demonstration by ECG-synchronized radionuclide cineangiography.

The findings of radionuclide cineangiography in Ebstein anomaly are described. The subjective findings in this case were similar to those of radiographic angiography, and there was objective evidence of tricuspid insufficiency. It is useful to recognize that Ebstein's anomaly is present before cardiac catheterization, since the procedure carries a relatively high risk of death in patients with this disorder.

Cleansing the colon in gallium-67 scintigraphy: a prospective comparison of regimens.

Colonic accumulation of gallium-67 frequently complicates the interpretation of gallium-67 scintigrams. Although various modes of cleansing the colon prior to scintigraphy have been suggested, there is controversy over their efficacy and none have been tested prospectively. Three hundred nine patients undergoing gallium-67 scintigraphy were randomly assigned to one of four cleansing regimens: (1) a high fiber diet (78 patients); (2) castor oil (76); (3) milk of magnesia and cascara (76); and (4) not preparation (79). Patient compliance rates for the four regimens were 17%, 32%, 36%, and 46%, respectively. After noncompliant patients were excluded, gallium-67 scintigrams were graded for colonic activity on a scale of 0-3 by three independent, experienced observers. Gallium-67 activity in the colon was significantly less after administration of castor oil than after no preparation (p = 0.047). A high fiber diet also resulted in a substantial reduction of colonic activity when compared with no preparation; the difference, however, was not statistically significant (p = 0.083). Regimen 3 did not produce significantly better results than regimen 4 (p = 0.42). A major impediment to the success of any cleansing regimen seems to be poor compliance of patients.
