microembolic signals (mes) are frequently observed in transcranial ‎doppler (tcd) recordings of patients with mechanical heart valve (mhv). if gaseous bubbles are the underlying cause, number of mes produced by mhv could be reduced with oxygen ‎inhalation. from september 2003 to september ‎2004, a consecutive series of 14 patients ‎with st jude aortic valve visited in the cardiology clinic were...

Real-time, B-mode ultrasonography provides the opportunity to improve the methods of evaluation of ovarian function and diagnoses of pregnancy in beef cattle. Determination of the sex of a fetus early in pregnancy (d 55 to 85) and verification of embryo viability by monitoring fetal heartbeat are unique methods involving ultrasound scanning. These techniques and a method for evaluating the tech...

In the past years, ultrasound imaging has become an integral element of the diagnostic process in rheumatic diseases. It enables the identification of a range of inflammatory changes in joint cavities, sheaths and bursae, and allows their activity to be assessed. In 2012, experts of the European Society of Musculoskeletal Radiology prepared recommendations concerning the role of ultrasonography...

Introduction Several methods for the acceleration of the healing process have been used, including electrical stimulation. Electromagnetic fields (EMFs) have direct biological effects on endochondrial cells and enhance the formation of callus (Gupta et al., 1991). Ultrasound is currently used for the diagnosis of osteoporosis (R. Strelitzki et. al., 1996). In this case, two ultrasound transduce...

Introduction: High-frequency ultrasound provides a modern, non-invasive method of skin visualization used for many years in dermatology. In this paper, we present the use of high-frequency ultrasound in monitoring the effects of treatment of selected dermatoses and a review of the literature on this topic. Material and methods: Ultrasound examination of the skin using a 20 MHz linear probe (Der...

The real-time monitoring of non-stationary targets for image guided therapy is critical for accuracy in determining the relative locations of organs. Currently, methods for obtaining real-time monitoring using image guidance involve expensive intra-operative equipment, ionizing radiation, or are limited to surface imaging of areas accessible through videoendoscopic tools. Of all imaging modalit...

BACKGROUND Osteoarthrosis is a common cause of low back pain. The diagnosis is clinical and can be confirmed by imaging studies. Pain treatment and confirmation of diagnosis are made by intra-articular injection of corticosteroid and by local anesthetic use, due to clinical improvement. A direct monitoring of the procedure can be done under fluoroscopy, a classic technique, or else by an ultras...

Placental chorioangioma is the most common subtype of non-trophoblastic placental tumors. Other subtypes are very rare and usually associated with an uneventful course of pregnancy. Most chorioangiomas are small and of no clinical significance. Giant chorioangiomas may be associated with serious fetal and maternal complications. So far, no established ultrasound guidelines are available for the...

complete bicornuate uterus is a type of mullerian duct deformity, resulting from abnormal duct fusion. similar to other mullerian anomalies, bicornuate uterus is associated with specific complications during possible pregnancies. while various studies have reported successful deliveries in a bicornuate uterus, it might be accompanied with various complications, ranging from preterm labor to mor...
