摘要:

AbstractWe have been using a high resolution real time ultrasound mechanical sector scanner to visualize the carotid bifurcation. Twenty‐six patients were studied before carotid arteriography for transient ischemic attacks. One bifurcation was not adequately visualized. Of the remaining 51, plaques were identified correctly in 29; absence of plaques was identified correctly in 15; small plaques were demonstrated by ultrasound in two that did not appear on the arteriogram; and four small plaques and one significant stenosis were not identified by ultrasoun

摘要:

AbstractCysts arising from the spleen are much less common than those arising from other organs such as kidney, liver, and ovary (1). Hemorrhagic cysts of the spleen are rare (1), but we have encountered two patients with this entity. The ultrasonograms in each patient demonstrated gravity‐dependent layering of two fluids of distinctly different echogenicity. The fluids were contained within a spherical mass. Acoustic enhancement was exhibited behind the mass in each case. This suggested the diagnosis of hemorrhagic cys

摘要:

AbstractRecent literature has suggested that total intrauterine volume (TIUV) estimation is useful for distinguishing normal from growth‐retarded fetuses. One hundred seventy‐nine measurements of TIUV were obtained from the ultrasonograms taken between 21 and 40 weeks of gestation in 140 patients who delivered average birthweight babies. We constructed a mean curve for TIUV with upper and lower 2.5 and 10% tolerance limits and later evaluated the TIUV's of 16 patients with growth‐retarded fetuses. Nine of these fetuses had birthweights below the fifth percentile for gestational age, and in each of these pregnancies the TIUV ultimately fell below the lower 2.5% tolerance

摘要:

AbstractUltrasonograms of most pseudocysts have a typical appearance — sharply defined, smooth wall, ovoid, located in the region of the pancreas. However, in reviewing the sonographic appearance of pseudocysts, other ultrasonographic characteristics may occasionally be encountered. Eleven patients with atypical pseudocysts are presented. The demonstration of multiple septations, multiple echoes within a sonolucent mass, and even failure to enhance posteriorly should not exclude the diagnosis of pancreatic pseudocyst in the proper clinical setting. The value of serial scans is also stressed. In this series, it was possible to suggest the diagnosis of infection, hemorrhage, and rupture of pseudocysts by demonstrating cysts with more typical appearances on prior examination

摘要:

AbstractFour patients with left atrial myxoma were studied using high speed B mode echocardiography with a mechanical sector scanning system. In all four patients, a mass of echoes was recognized in the left atrial chamber during systole. Its lower portion protruded into the left ventricle through the mitral orifice in diastole. The degree of protrusion of the tumor echo varied. An analysis of three cross sections, long axis of left ventricle, sagittal and horizontal axes, showed that the tumor moved anterosuperiorly to posteroinferiorly in the left‐sided heart chambers. Its movement was clearly observed in real time. The echo pattern from the tumor had an appearance of mottling, not layering. The myxomas were successfully removed from the left atrial chambers by surgical intervention in all case

摘要:

AbstractUltrasonic visualization of normal and pathological Wirsung's ducts has become quite common, especially with the newest gray scale units. Ductal images were studied in 17 cases of quiescent chronic pancreatitis. Duct dilatation could be identified in the majority.
