OBJECTIVE To correlate the quantitated tumor vascularity of implanted murine tumors as depicted by contrast-enhanced sonography with estimates made with magnetic resonance imaging and with estimates of the percentage of viable (metabolically active) tumor as depicted by fluorodeoxyglucose autoradiography. METHODS Implanted tumors in 10 mice were imaged with contrast-enhanced sonography, magne...

OBJECTIVE The purposes of this study were (1) to review the sonographic in vitro and in vivo appearances of mesh for surgical repair of abdominal wall hernias, (2) to describe sonographic techniques and discuss the limitations of sonography in evaluation of mesh hernia repair, and (3) to illustrate common complications after mesh repair shown with sonography. METHODS We identified interesting...

Sonography has been the fundamental pillar of fetal diagnosis, and until relatively recently, no other valid and reliable noninvasive technique that could adequately determine fetal morphology was available. However, even after the technological advances in obstetric sonography, is still unable to detect some anomalies. One example of this shortcoming is the morphological study of the face and ...

Focal splenic lesions are uncommon and generally difficult to diagnose, as they do not show a specific radiological semiology and do not provide enough clinical and/or laboratory data. Thus, sometimes the association of various imaging tests, the fine-needle aspiration or even long-term follow-up monitoring of the patient is required to determine the true nature of the lesion (1). The realizati...

Transcranial sonography is a highly sensitive noninvasive sonographic method for detection of early and specific echogenic changes in basal ganglia of patients with some neurodegenerative diseases. Transcranial sonography showed substantia nigra hyperechogenicity as a typical echo feature in idiopathic Parkinson disease and lenticular nucleus hyperechogenicity as a characteristic finding in aty...

Introduction. Thoracic subcutaneous emphysema may be caused by various pathologies. In mechanically ventilated patients, timely diagnostic workup is particularly important, as the presence of subcutaneous surgical emphysema may indicate pneumothorax, representing a risk factor for the development of life threatening tension pneumothorax. Thoracic ultrasound is of proven value for the detection ...

[Purpose] This review article is designed to expose the application of sonography in shoulder pain after stroke. [Methods] A range of databases was searched to identify articles that address sonography examination, with or without ultrasound guided corticosteroid injection for hemiplegic shoulder pain (HSP). The electronic databases of PubMed, CENTRAL, CINAHL, Cochrane Library, Medline were sea...

background : rectal bleeding is a relatively uncommon, but potentially important problem in early infancy.  the common causes of fresh rectal bleeding in this age group are: bleeding diathesis (vit. k deficiency), infectious colitis, cow’s milk protein allergy and anal fissure.  nodular lymphoid hyperplasia (nlh) is another cause of prolonged fresh rectal bleeding in early infancy.   objective:...

LETTERS Sonography as a replacement for sialography for the diagnosis of salivary glands affected by Sjögren's syndrome Recently, it has been suggested that sono-graphic evaluation of the salivary glands is useful in the diagnosis of Sjögren's syndrome. Kawamura et al and, more recently, Ariji et al, showed that descriptive and quantitative assessment of the salivary glands by sonogra-phy effic...

Objective The purpose of this study was to establish an association between the body mass index (BMI) group and anatomical gallbladder position aid novices in sonography. Methods This a cross-sectional, Strengthening Reporting Observational Studies Epidemiology (STROBE)-compliant that examined gender BMI with quantitative measurements from computed tomography (CT) scans. Results A analysis dete...
