OBJECTIVE We wanted to investigate the ability of breast MR imaging to identify the primary malignancy in patients with axillary lymph node metastases and initially negative mammography and sonography, and we correlated those results with the conventional imaging. MATERIALS AND METHODS From September 2001 to April 2006, 12 patients with axillary lymph node metastases and initially negative ma...

OBJECTIVE The purpose of this study was to review the technical aspects and the clinical applications of intraoperative sonography of the central nervous system (CNS) as well as the characteristic appearances of brain and spine diseases. METHODS A pictorial review of cases is presented on the basis of the performance and interpretation of intraoperative sonography of the CNS from January 1998...

OBJECTIVE To show the advantages of extended field-of-view sonography in abdominal applications. METHODS Thirty-one cases were prospectively analyzed in our study. Extended field-of-view images were obtained when the radiologist decided that they would offer potential advantages for the examination. When extended field-of-view scanning was used, the radiologist determined prospectively whethe...

BACKGROUND Jumper's knee is a common and troublesome condition among senior volleyball players, but its prevalence among elite junior players compared to matched non-sports active controls is not known. OBJECTIVE To clinically, and by sonography, examine the patellar tendons in elite junior volleyball players (15-19 years) at the Swedish National Centre for volleyball and in matched controls....

CONTEXT AND OBJECTIVE The initial method for evaluating the presence of pleural effusion was chest radiography. Isolated studies have shown that sonography has greater accuracy than radiography for this diagnosis; however, no systematic reviews on this matter are available in the literature. Thus, the aim of this study was to evaluate the accuracy of sonography in detecting pleural effusion, by...

Background: To compare pregnancy outcomes in women at risk for cervical incompetence after elective versus ultrasound indicated cerclage. Methods: In a prospective randomized trial, singleton pregnancies with at least one previous spontaneous midtrimester loss or early preterm delivery (between 15 and 32 weeks’ gestation) who met clinical criteria for the diagnosis of cervical incompe­ tence we...

BACKGROUND The detection of hyperechogenicity of the substantia nigra using trans cranial sonography can be predictive of the diagnosis of Parkinson Disease. AIM To report an experience with transcranial sonography for the diagnosis of Parkinson disease. Material ana METHODS One hundred sixteen patients with movement disorders were subjected to a transcranial sonography to detect the presen...

A prospective blind comparison was completed between duplex sonography and angiography of the vertebral arteries. Thirty-two vertebral arteries were studied for direction of flow, degree of origin plaque or stenosis, Doppler characteristics, and vessel size. The vertebral arteries were reliably identified by imaging their course from the subclavian artery into the transverse foramina and by ide...

OBJECTIVES The human chorionic gonadotropin (hCG) discriminatory level-the maternal serum β-hCG level above which a gestational sac should be consistently visible on sonography in a normal pregnancy--has been reported to be 1000 to 2000 mIU/mL for transvaginal sonography. We assessed whether a woman with a β-hCG above 2000 mIU/mL and no intrauterine fluid collection on transvaginal sonography c...

This study compares the sonographic and CT findings in a group of infants with macrocrania and correlates those findings with neurologic outcome to determine the diagnostic accuracy and prognostic value of sonography. Sonographic findings in 255 infants with macrocrania are described. Of the 195 term infants examined, 130 had normal sonograms, 11 (5.6%) had significant abnormalities, and 54 had...
