Problems in the application of ultrasonography for the evaluation of pleural opacities.

Fifty-nine patients with pleural abnormalities on chest radiographs were evaluated by B-mode ultrasonography; the lesions were categorized as echo-free or complex. Echo-free lesions included pleural fluid collections, and abnormalities which did not yield "fluid" through an appropriately positioned large caliber needle. "Complex appearing" lesions yielded fluid through a needle in all cases. Ultrasonography could not accurately predict which lesions were amenable to successful thoracocentesis. Findings from recent radiographs and clinical history must be known when the ultrasonographic findings in patients with chest abnormalities are interpreted.

Computed tomographic evaluation of the diaphragmatic crura.

The diaphragmatic crura have a variable appearance on CT body scans. They can at times appear quite prominent and be easily confused with other anatomical or pathological structures. Analysis of the CT scans of 100 patients revealed certain characteristic features of the diagphragmatic crura that help distinguish them from other structures, especially enlarged para-aortic lymph nodes.

Comparison of computed tomography, ultrasonography, and gallium-67 scanning in the evaluation of suspected abdominal abscess.

A retrospective study was made of 29 consecutive patients who were evaluated for suspected abdominal abscess by at least two of three imaging modalities: gallium-67 scanning, ultrasonography, and computed tomography. No statistically significant difference in accuracy of the findings could be demonstrated. Consideration of the advantages and disadvantages of each imaging modality will often indicate which to use in an individual case. Findings from the three imaging techniques sometimes provided complementary rather than identical information.

Capability of CT body scanning and ultrasonography to demonstrate the status of the biliary ductal system in patients with jaundice.

The capability of ultrasonography and computed tomographic body scanning to demonstrate the status of the biliary tract was studied prospectively in 23 jaundiced patients. Ultrasonography correctly indicated the presence or absence of obstruction in 21 of the 23 patients and CT scanning in 20. Both procedures correctly demonstrated no evidence of ductal dilatation in the five patients who had nonobstructive jaundice. Retrospective study of the same material increased the accuracy of CT scanning (22 of 23 patients) because of recognition of common bile duct dilatation in the absence of intrahepatic duct dilatation. The accuracy of ultrasonography was unchanged.

Ultrasonographic appearance of gas-containing abscesses in the abdomen.

This report describes the sonographic appearance of six gas-containing abdominal abscesses. Gas-containing abscesses may appear as densely echogenic masses with acoustical shadowing, but may also be seen merely as regions of acoustical shadowing or as an echogenic mass. A hypothesis is advanced that the appearance of gas-containing abscesses as echogenic masses may be due to a "microbubble" constrast effect.

Analysis of ultrasonographic criteria in the evaluation for ectopic pregnancy.

To assess the usefulness of ultrasound in diagnosing ectopic pregnancy, the ultrasonographic findings, pregnancy test results, and proven diagnoses in 148 patients referred for evaluation for ectopic pregnancy were reviewed. Of these patients, 33 were subsequently proven to have ectopic gestations. The ultrasonograms were coded for uterine size, intrauterine gestation sac, adnexal mass, adnexal ring, cul-de-sac fluid, or normal findings. With a positive pregnancy test, the presence of an intrauterine gestation sac excludes the diagnosis of ectopic pregnancy. Of those patients with positive pregnancy tests and no intrauterine gestation sac, 73% had ectopic pregnancy. All patients with normal ultrasonograms had other diagnoses. With a negative pregnancy test, the intrauterine findings are not helpful, and evaluation of the adnexa is more important. An adnexal ring is a significant, though not absolute, indicator of ectopic pregnancy. A normal scan excludes this diagnosis. Other criteria were not significant. A clinical approach to the evaluation for ectopic pregnancy, based on the data accumulated in this study, is suggested.

Rapid B-scan (real-time) ultrasonography in the identification and evaluation of twin pregnancies.

Real-time ultrasonography utilizing a hand-held linear array transducer provides a highly accurate method of identifying and evaluating the twin gestation. The rapidity of real-time scanning eliminates interpretational problems caused by fetal movements. Additionally, the versatility of transducer positioning facilitates recognition of appropriate fetal planes for assessment of viability and growth. A prospective study of 595 consecutive pregnancies yielded no misdiagnoses of the number of fetuses present and only one false positive diagnosis of fetal viability.

Mature placenta simulating fetus papyraceus on ultrasonic examination.

A case of a heavily calcified, mature placenta simulating the appearance of a fetus papyraceus is presented. Calcification surrounding the more sonolucent cotyledons simulated the body and limbs of a dead fetus. Awareness of the morphologic alterations which occur as the placenta matures should prevent confusion of normal placental changes with a pathologic entity.

Ultrasonography in the evaluation of nontraumatic abdominopelvic emergencies.

Ultrasonography can provide prompt diagnostic information in many non-traumatic abdominal and pelvic emergencies. The safety of of diagnostic ultrasonography enables its use in many emergency situations that relate to pregnancy. The ability to demonstrate normal fluid-filled organs with clarity makes ultrasonography valuable in the emergency assessment of the gallbladder and aorta. Similary, ultrasound is sensitive to the detection of pathologic collections of fluid that can be applied in the search for abscesses or hematomas. Finally, ultrasonography is independent of organ function. In this regard, it is a useful ancillary test when radiographic examinations of the biliary or urinary tracts fail because of poor contract excretion.

Prenatal diagnosis of beta-thalassaemia and sickle-cell anaemia. Experience with 24 cases.

Prenatal diagnosis of beta-thalassaemia and sickle-cell anaemia was attempted in 24 pregnancies. Adequate amounts of fetal blood (for studying globin-chain synthesis) were obtained in 22 cases. 4 cases of homozygous beta-thalassaemia and 2 of sickle-cell anaemia were diagnosed. The difference between the homozygous and non-homozygous states was well defined. Fetal bleeding from cord puncture and amnionitis resulted in the loss of three fetuses, and methods to avoid these complications are being devised. It is concluded that prenatal diagnosis of disorders of beta-globin synthesis is feasible.

Prenatal diagnosis of achondrogenesis.

Severe rhizomelic and mesomelic dwarfism was demonstrated in a 20-week gestation fetus by amniography. A systematic progressive approach to prenatal diagnosis in the absence of a definitive diagnosis and the use of contrast radiography is discussed.

Prenatal diagnosis of dysplastic kidney disease.

Sonolucent areas in the region of the kidneys were demonstrated by ultrasound in a 23-week-old fetus. These sonolucent areas persisted and enlarged during the pregnancy and the infant had the Potter phenotype and Potter type 2A dysplastic kidneys at birth. The use of prenatal sonographic evaluation of the fetal kidneys is discussed.

Use of simethicone as a patient preparation for abdominal sonography.

Fifty-eight patients about to undergo abdominal ultrasonography were randomly assigned into groups receiving preparation with oral simethicone and into control groups. A percentage value of sound transmission through the abdomen was calculated for each patient using sonographic measurements taken from a series of prescribed scans by a sonographer unaware of the patient preparation employed. Results indicate a statistically significant improvement in through sound transmission for those groups receiving simethicone preparation.

Accuracy of real-time sonography in the determination of fetal viability.

After 8 weeks of fetal age, real-time ultrasonography is a simple, rapid, and highly reliable technic for differentiating a viable from a dead fetus. Fetal movements are invariably detected after 8 weeks of fetal life, and a discrete, fluid-filled, intrathoracic pulsating heart can be seen after 11-12 weeks of fetal life. Absence of these findings, as observed by two independent examiners each viewing the fetus for 3 minutes with real-time sonography, provides reliable evidence of fetal demise. A prospective evaluation of 390 consecutive fetuses yielded only one false positive diagnosis of fetal viability. No living fetus was diagnosed as being dead.
