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...

Real-time computed sonography was used to monitor ventricular size in kittens with experimentally induced hydrocephalus. Hydrocephalus was induced by cisternal kaolin injection in newborn kittens in order to study the effects of both hydrocephalus and subsequent ventriculoperitoneal shunting on the morphology of brain tissue. When severe hydrocephalus was achieved, marked physical and neurologi...

Duplex Doppler sonography has been recognized as a noninvasive method to evaluate hemodynamic features of renal blood in renal and intrarenal arteries in patients with various renal diseases. The significance of duplex Doppler sonography in the evaluation of renal vascular resistance in glomerular diseases has not yet been clearly determined. The aim of the present study was to evaluate renal v...

BACKGROUND AND OBJECTIVES Long-term administration of tamoxifen causes endometrial changes. The aim of this study was to evaluate the role of transvaginal sonography and vaginoscopic hysteroscopy in the screening of patients on tamoxifen. METHODS Seventy patients with breast cancer treated with tamoxifen 20 mg daily underwent transvaginal sonography and vaginoscopic hysteroscopy, a modified r...

OBJECTIVE This prospective study evaluated the ability of indirect 16-row multidetector CT venography, in comparison with Doppler sonography, to detect deep vein thrombosis after total hip or knee replacement. MATERIALS AND METHODS Sixty-two patients had undergone orthopedic replacement surgery on a total of 30 hip joints and 54 knee joints. The CT venography (scan delay time: 180 seconds; sl...

OBJECTIVE The goal of this review article is to present the state of the art in the clinical applications and technical performance and interpretation of carotid sonographic examinations. METHODS Relevant publications regarding color and duplex Doppler sonography (CDDS) of the carotid arteries extracted from a computerized database (MEDLINE) and from references cited in these articles not app...

BACKGROUND AND PURPOSE Pericallosal lipomas are rare tumors. Few reports have included their imaging characteristics. Furthermore, little is known about their evolutive course. Our purpose was to describe the imaging features of seven cases of pericallosal lipoma diagnosed in utero and followed up after birth. METHODS We reviewed seven cases of pericallosal lipoma diagnosed by obstetric sonog...
