Advances in transcranial doppler ultrasonography

Current Neurology and Neuroscience Reports, 2008
Transcranial Doppler ultrasonography (TCD) is the only noninvasive real-time neuroimaging modality for the evaluation of characteristics of blood flow in basal intracerebral vessels that adds physiologic information to structural imaging. TCD has been rapidly evolving from a simple noninvasive diagnostic tool to an imaging modality with a broad ...

Transcranial Doppler Ultrasonography

Neurosurgery Clinics of North America, 1994
Transcranial Doppler ultrasonography is an extremely useful adjunct in neurosurgical intensive care. Continuous improvements in TCD equipment as well as computer software have improved examination success and also vessel identification. Recent expanding applications of TCD have also allowed the study of disorders of control of the cerebral circulation.

Doppler Ultrasonography and Contrast-Enhanced Ultrasonography

Choonpa Igaku, 2006
胆道疾患に対する超音波カラー・パワードプラ法と造影超音波に関する最近の知験をレビューした. 超音波カラー・パワードプラ法は脈管と胆管の鑑別に有用であり, これは閉塞性黄疸時における経皮経肝的胆道ドレナージを安全に施行するために有用である. 一方, 胆嚢内腫瘤の鑑別にも超音波カラー・パワードプラ法は有用であり, 胆嚢癌では腫瘍血管および胆嚢動脈の最高流速が上昇する. 胆嚢癌のhigh risk groupである膵胆管合流異常は, 胆嚢壁の動脈流速が上昇するといわれ, カラードプラ法が診断の契機となる. 胆嚢ポリープの鑑別においては, 胆嚢癌は造影超音波で樹枝状の血管構築を呈することが多い点が他のポリープとの鑑別点になる.

Transcranial doppler ultrasonography

Journal of neurology, neurosurgery, and psychiatry
Abstract Transcranial Doppler ultrasonography (TCD) is a noninvasive, bedside procedure that can detect blood flow in the proximal cerebral intracranial arteries. TCD has multiple applications, including rapid assessment of anterior circulation blood flow in acute, large-vessel occlusion. For patients with subarachnoid hemorrhage, trends

Ultrasonography and Doppler Techniques

2019
Acute kidney injury (AKI) is characterized by a rapid loss of kidney excretory function. Ultrasound (US) helps nephrologists in AKI diagnosis, in order to describe and follow kidney alterations and find possible causes of AKI. US is a safe, non-invasive, and repeatable imaging technique.

Ultrasonography of the pancreas. 3. Doppler imaging

Abdominal Imaging, 2006
Ultrasonography is probably the most widely used medical imaging technique. In fact, its non-invasivity, portability, widespread distribution and good clinical results have made it the preferred method for a first imaging approach to patients in a large variety of clinical settings.

Doppler ultrasonography of the pelvis.

Radiologic clinics of North America, 1992
TVS has brought the pelvic organs closer to us than ever before. Color Doppler probes have exposed small vessels that could not be seen with real-time technique alone, and pulsed Doppler is becoming an important adjunct in many physiologic and pathologic states.

Application of Doppler Ultrasonography in Cattle Reproduction

Reproduction in Domestic Animals, 2007
ContentsThe development of Doppler processing extended the scope of sonographic imaging from an anatomical to a physiological basis. This technique became established as a clinical tool in human gynaecology. For example, it has been discussed that the implantation of an embryo is influenced by the uterine blood flow.
