AbstractIn an effort to evaluate the efficacy of measuring abdominal circumference with real‐time ultrasound, 53 patients were scanned with both contact scanning and linear array real time. Image measurements were made blindly from both types of equipment. Abdominal circumference measurements with real time compared favorably with those obtained from contact images (r = +0.984

摘要:

AbstractTwo patients with metastatic carcinoma (one cervical and one testicular) in whom echocardiography was instrumental in diagnosing a right ventricular cavity mass are presented. In the first case the M‐mode echocardiogram revealed dense echoes in the right ventricle and right ventricular outflow tract during systole and diastole. Surgical confirmation of the mass lesion was obtained. The second case also revealed abnormal echoes in the right ventricle and right ventricular outflow tract, but they were less dense and distinct. Two‐dimensional echocardiography clearly delineated a highly mobile mass of tissue in the right ventricle which corresponded to the necropsy findi

摘要:

AbstractFive cases of gastrointestinal leiomyosarcoma were studied by ultrasound. Sonographic features of a huge mass with a thick echogenic rim and central sonolucent cavitation were seen in four cases with presenting symptoms of an abdominal mass. In a fifth case necrotic metastasis was seen in the liver after removal of a leiomyosarcoma. Although not pathognomonic, such features should strongly suggest the diagnosis of leiomyosarcoma.

摘要:

AbstractOne hundred uncomplicated pregnancies of primigravida and secundigravida gestation were scanned within 24 hr of delivery. The ultrasonic appearances of the uterus were categorized into three groups: (1) empty uterus; (2) cavity separation indicating blood or clot; and (3) dense cavity echoes representing retained tissue. The presence of blood and clot in the puerperium is a common occurrence that resolves spontaneously. Retained tissues of conception were present in 10 cases and were passed spontaneously in four women within the first 3 days postpartum. The presence of retained tissue after the fourth day is support for surgical evacuation of the uterus. Gray‐scale ultrasonic examination was accurate in diagnosing all of these case

摘要:

AbstractThe ultrasonic characteristics of bilomas are reviewed in five patients, one of whom was also studied with computed x‐ray tomography. Certain features not previously reported should aid in differentiating bilomas from other intra‐abdominal fluid collecti

摘要:

AbstractThe effect of B‐scanner articulated arm angle measurement errors on B‐mode registration is considered. For a single‐angle articulated arm model, a mathematical equation predicting B‐mode misregistration as a function of angular errors and compound scan angle is derived and discussed. This model accurately predicts registration errors for transducer connector/acoustic axis misalignment or third arm angle

摘要:

AbstractA sonographic survey of 100 patients with suspected abdominal aortic, femoral, or popliteal arterial aneurysms was conducted over a period of 2 yr. Patients referred for suspected abdominal aortic aneurysms had a low incidence of associated lower extremity arterial aneurysms. Those patients referred for possible femoral or popliteal artery aneurysms frequently had multiple other peripheral arterial aneurysms. The authors recommend a survey scanning protocal in this subgroup with lower extremity aneurysms to rule out the presence of other aneurysms.

摘要:

AbstractWe have performed a total of 126 ultrasound scans of the brain in 86 different neonatal patients with a 7.0 MHz linear array transducer (6.5 cm in length), using the anterior fontanelle as a scanning window. Thirty‐one patients had demonstrable abnormalities confirmed by CT while 49 patients were normal. Using this technique we were able to reliably define normal lateral ventricles, subependymal hemorrhages, hematomas, intraventricular hemorrhages, hydrocephalus, and porencephalic cyst
