in this regards first of all cross sectional anatomy of salivary glands and different diagnostic modalities such as ultrasound, cat scan, conventional mri and nuclear studies will be discussed. advanced mri modality such as dce (dynamic susceptibility enhanced) imaging will be introduced. then various pathologies of salivary glands including infectious, benign and malignant neoplastic processes...

Both cross-sectional histological studies of human atherosclerotic specimens and a plethora of studies in animal models have provided the current framework for the pathogenesis of atherosclerosis. One major drawback of the current hypotheses is the paucity of longitudinal observations in humans on the natural history of atherosclerosis. Noninvasive imaging studies of human atherosclerosis are a...

OBJECTIVES This study attempted to identify the clinical, angiographic, procedural and intravascular ultrasound predictors of directional atherectomy results assessed by intravascular ultrasound. BACKGROUND Several angiographic and intravascular ultrasound variables have been associated with the outcome of directional coronary atherectomy. No study has incorporated both modalities into a pred...

BACKGROUND Routine imaging follow-up after endovascular treatment of abdominal aortic aneurysms (EVAR) is mainly aimed at detection of endoleaks. The aim of the study was to assess changes in the size of the abdominal aortic aneurysm sack using CT angiography (CTA) after successful treatment using endovascular stent graft implantation. MATERIAL/METHODS A retrospective analysis of CTA results ...

OBJECTIVES To demonstrate that parasagittal constructive interference in steady state (CISS) magnetic resonance imaging (MRI) can be used to accurately measure cochlear nerve cross-sectional area and thereby evaluate for statistically significant differences in the cochlear nerve cross-sectional areas of postlingually deafened and normal-hearing adults. STUDY DESIGN Cross-sectional study. S...

Sinus of Valsalva aneurysm, dilatation of one or more of the aortic sinuses, is a rare but important aortic root defect, which can be a cause of some serious cardiac sequels. The purpose of this article is to review the etiopathogenesis, relevant anatomy, clinical manifestations, potential complications, multimodality imaging features, and management of this rare but important entity of sinus o...

Gynecologic cancers are a common cause of morbidity and mortality in women of all ages. While many gynecologic cancers are staged clinically using the International Federation of Gynecology and Obstetrics (FIGO) staging system, imaging can be a useful adjunct to clinical staging. Cross sectional imaging techniques such as ultrasound (US), computed tomography (CT) and magnetic resonance imaging ...

The cross-sectional echocardiographic demonstration of the "goose-neck" deformity is described in four patients with endocardial cushion defect. The diagnosis was confirmed in each patient by left ventricular angiocardiogram. The subxiphoid approach of cross-sectional echocardiography in diastole allowed visualization of an elongated, narrowed, and somewhat horizontally inclined configuration o...

Tomographic imaging techniques such as ultrasound can provide important information in the evaluation of vascular anatomy. Recent technical advances have permitted fabrication of a small (1.83 mm), phased-array, intravascular ultrasonic imaging catheter capable of continuous real-time, cross-sectional imaging of blood vessels. We used this imaging catheter to compare intraluminal ultrasound wit...
