Focused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with hydrocephalus. Normal-pressure hydrocephalus (NPH) is characterized by often incapacitating gait dysfunction, cognitive impairment, and urinary incontinence, with the presence of enlarged ventricles despite normal intracranial pressure ().Gait disorders are the initial manifestations; other symptoms appear as the disease progresses (). Jan 10, 2019 - In this video lecture you will learn how to image and diagnose fetal hydrocephalus (ventriculomegaly) using 2D and 3D/4D ultrasound Radiology. Although ultrasound is highly effective in evaluation of hydrocephalus in the neonate and infant, the complete closure of cranial sutures and increased skull thickness in the adult makes ultrasonography ineffective for evaluation of adult-onset hydrocephalus. For 15 men who had undergone neurosurgery, ultrasound of the brain through the surgically created cranial defects identified the status of the ventricles in 15 of 17 total examinations (88%). Radiology Departement of the Maastricht University Hospital, Academical Medical Centre in Amsterdam and the Alrijne hospital in Leiderdorp, the Netherlands Publicationdate 2018-02-09 This is an overview of normal values of ultrasound examinations in neonates and children. Sometimes congenital hydrocephalus is detected before birth, during a pregnancy ultrasound scan. Normal pressure hydrocephalus (NPH) is a syndrome found in the elderly, which is characterized by ventriculomegaly and deep white matter ischemia (DWMI) on magnetic resonance imaging (MRI) and the clinical triad of gait disturbance, dementia, and urinary incontinence. H ydrocephalus may be life threatening and require emergency surgical treatment. The third ventricle (3 rd) is dilatated secondary to hydrocephalus. Stichting Radiology Assistant - ANBI; Information; Apps. Ultrasound is a safe, quick, non-invasive & repeatable modality, has a definite role in the diagnosis of hydrocephalus.

This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue. Sonography can be useful for: (1) detecting ventriculomegaly, (2) differentiating nonobstructive ventricular dilatation from obstructive enlargement (hydrocephalus), (3) determining the cause of hydrocephalus; (4) aiding in the temporary management of patients with hydrocephalus; and (5) aiding in the management of patients with permanent ventricular shunts.
