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...

background: breast cancer is the most common type of cancer in women demanding time and accurate diagnosis to take remedial measures to treat. objective: comparing the diagnostic capability of the computer regulation thermography (crt), as a novel and safe dignostic procedure, with common clinical examination and imaging methods including sonography and mammography for diagnosing breast cancer ...

according to its superficial anatomical location, the thyroid gland is easily accessible by sonography. sonography allows an exact documentation of the size and thyroid volume. the relationship between thyroid volume and anthropometric characteristics is a matter of controversy. the aim of this study was to investigate thyroid volume and its determinants in healthy adult. a cross-sectional stud...

background: major depression is a common disorder with great social and individual burdens. transcranial sonography (tcs) is a useful and noninvasive measure for assessment of normal and impaired brain parenchyma. the brainstem raphe nuclei are in close association with dorsocaudal limbic system and plays an important role in depression. in this study we compared the echogenicity of the raphe n...

INTRODUCTION The aim of this study was to clarify the effectiveness of various imaging modalities and characteristic imaging features in the screening of IgG4-related dacryoadenitis and sialadenitis (IgG4-DS), and to show the differences in the imaging features between IgG4-DS and Sjögren's syndrome (SS). METHODS Thirty-nine patients with IgG4-DS, 51 with SS and 36 with normal salivary glands...
