The nature of pleural based radiographic opacities in the chest can be uncertain; however, ultrasonic examination provides a reliable means of distinguishing solid from fluid-containing lesions. It is superior to both fluoroscopy and radiography in accurately localizing loculated fluid collections for thoracentesis and can be performed with commercially available gray scale contact scanning equipment. Cases representing a spectrum of clinical applications are discussed. 相似文献

Real-time sonography of pleural opacities 总被引:1,自引:0,他引:1
Fifty patients with radiographic pleural or pleural-based opacities were examined with high resolution real-time sonographic sector scanning. In 90% of cases selected for thoracentesis, fluid sufficient for diagnosis was obtained. Complex, septated pleural loculations contained an exudative effusion in 74% of the patients, while anechoic areas yielded exudative and transudative effusions with almost equal frequency. The use of real-time scanning is stressed because of greater flexibility and shorter examination time compared to compound scanning, and its utility for portable scanning on critically ill patients. 相似文献

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. 相似文献

The value of ultrasounds in the location of small pleural opacities was investigated. A correlation between conventional radiological and echographic signs was made to define the echographic signs useful in the identification of peripheral pleural and parenchymal lesions. 相似文献

The authors evaluated the diagnostic reliability of echotomography in detecting parathyroid masses: 37 patients were studied with primary hyperparathyroidism, in four cases recurrent. They all underwent surgical ablation of the mass, identification of all glands, and biopsy of an apparently normal parathyroid. Echotomography was accurate in 91.4% of cases: it identified 27 out of 39 pathological glands (sensibility 69.2%) and gave no false-positive results (specificity 100%). Since parathyroid is often ectopic, oblique scans are suggested, i.e. of jugulum while the patient is swallowing. Such scans were always used in our study, in order to identify lesions even in case of "difficult" locations, such as the superior mediastinum. 相似文献

Ultrasonography has proved to be a highly useful method for detecting testicular lesions, correlating them with clinical findings, and indicating whether scrotal masses are caused by fluid or by solid tissue. It has not been possible, however, to distinguish spermatic cord torsion from epididymitis. 相似文献

Peyronie disease, or Induratio Penis Plastica, is characterized by the presence of one or more fibrous plaques at the albuginea penis, on the cavernous bodies or on the intercavernous septum. First of all, Induratio Penis Plastica etiology is described, and its clinics and therapy. Past imaging methods are then considered (i.e. conventional radiology, xerography), and current ones (i.e. conventional radiology, cavernosography, CT and US). The authors report on their 4-year (1983-1987) experience with US in 62 males. Various different probes were employed, especially small-part 7.5 MHz probes. The results are similar to those reported in international literature. The use of high frequency probes allows the evaluation of focal hypoechoic lesions even in the early phase of the disease, thus helping make therapy more effective. 相似文献

Nine patients with radiographic evidence of renal calculi were evaluated with gray scale renal ultrasonography. A characteristic "sonic shadow" caused by the calculus was adequately demonstrated in each case. This paper discusses the advantage of ultrasound in evaluating the presence of nonopaque and opaque renal stones. 相似文献

Summary The ratio of lateral ventricle to hemispheric width was measured in 200 normal pregnancies. Statistical curve fitting was tried to predict normal value and 5 and 95 percentiles. Anatomical sections of fetal head are provided to correlate the ultrasonic pictures. A typical case of application is described.Original presentation: 9th Congress of the European Society of Neuroradiology Brussels, 12–13 September 1980 相似文献

Ureteroceles appear as transonic intravesical lesions on ultrasonic demonstration of the bladder, producing a 'cyst within a cyst' appearance. Four patients, three with simple ureteroceles and one with an ectopic ureterocele were investigated by intravenous urography (IVU), ultrasound (US) and cystoscopy. Two patients had bilateral simple ureteroceles with non-dilated ureters and two had unilateral ureteroceles, one simple, and one ectopic with a hydroureter. Previously ultrasonography of the fluid-filled bladder has demonstrated only large ureteroceles. The present study was successful in demonstrating both large and small ureteroceles. 相似文献
