Ultrasound plays an increasing role in the evaluation, monitoring, and treatment of infertility. About 15% of all couples attempting to have children are affected by infertility. As women delay conception due to career choices and age, the frequency of infertility increases. Infertility is defined as no conception after one year of unprotected intercourse. Ultrasound plays a remarkable role in ...

Reliability of 804 indirect measurements of systemic arterial blood pressure (BP) was assessed in 13 cats by comparing results obtained indirectly by oscillometry (BPo) and Doppler ultrasonography (BPud) with those obtained simultaneously by a reference method, direct radiotelemetry (BPrt). The reliability varied considerably among sites of cuff placement and method of indirect measurement in c...

Objective: Obstetricians, Neonatologists, and Pathologists have studied gross histological analysis of human placentas in search of specific alterations in placental functions that can be correlated with neonatal outcomes. Our study assessed the prevalence of abnormal placental findings associated with non-reassuring fetal monitoring in labor requiring emergent instrumental or cesarean delivery...

The occurrence of a fetal tumor is rare, 50% of all fetal tumors being sacrococcygeal teratomas. Prenatal diagnosis of this condition is important for the monitoring of the affected fetuses and for establishing the mode and time of delivery. We describe two cases of fetal sacrococcygeal teratoma diagnosed by 2D- and 3D-ultrasound. Three-dimensional ultrasound proved to be useful both in the dia...

Introduction: Tracking muscle movement can be very useful in diagnosis and rehabilitation of patients with neuromuscular disorders. Doppler ultrasound is well suited for analysis of musculoskeletal movement, but conventional ultrasound systems are bulky and not suitable for monitoring patients during ambulatory gait. A wireless Doppler ultrasound system can allow for direct measurement of muscu...

Ultrasonic methodologies of air-coupled guided waves, birefringent shear waves, and nonlinear ultrasound are presented and applied to the characterization of aerospace materials. The guided waves generated by air-coupled ultrasound provide non-contact monitoring of in-plane stiffness anisotropy and high-contrast imaging of defects in a single-sided access configuration. Mapping of local fibre o...

Background/introduction Combining focused ultrasound (FUS) with real time MRI guidance and monitoring enables a new non-invasive treatment of brain disorders. In this technique multisource ultrasound waves are focused at a single point raising the temperature gradually until ablation occurs. Lesions as small as 2-4 mm can be made, without impact on surrounding tissue or remote brain tissue. Our...

A wide range of clinical techniques and investigations is available to healthcare professionals to survey the condition of a fetus in the womb. These may be deployed from early pregnancy to birth. They range from the use of traditional equipment such as a Pinard's stethoscope, which allows direct auscultation of the fetal heartbeat, to ultrasound imaging of the fetus, which gives an ever-increa...

Gout is a frequent inflammatory disease induced by the deposition of monosodium urate crystals in joints and extra-articular tissues. The natural history of the disease includes four different phases: asymptomatic hyperuricemia, acute attacks, intercritical phase, and chronic tophaceous gout. Imaging techniques have several applications in the diagnosis, clinical monitoring and management of th...

OBJECTIVE To illustrate the possible role of cerebral oximetry and stroke distance as measured by Doppler ultrasound in monitoring the critically ill patient non-invasively in the emergency department. METHODS Five critically ill patients were monitored with either cerebral oximetry or both cerebral oximetry and stroke distance (the distance travelled by blood in the aorta with each ventricul...
