Advances in transcranial doppler ultrasonography
Current Neurology and Neuroscience Reports, 2008Transcranial 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 ...

Hysterosalpingography with color Doppler ultrasonography
American Journal of Obstetrics and Gynecology, 1991To assess the accuracy of the diagnosis of tubal occlusion with the use of color Doppler flow ultrasonography and hysterosalpingography, 129 infertile women were studied. All 129 women had the procedure performed with an ATL Ultramark 9 (Advanced Technology Laboratories, Bothel, Wash.) color Doppler ultrasonography machine. Eighty-five of the 129 women

Transcranial Doppler Ultrasonography
2019Abstract Transcranial Doppler (TCD) ultrasonography is a diagnostic technology for ascertaining numerous physiologic and pathologic phenomena by monitoring the direction and velocity of blood flow in intracranial vasculature. It is a noninvasive, point-of-care diagnostic tool that provides continuous and reproducible bedside data without

Transcranial colour Doppler ultrasonography
Rivista di Neuroradiologia, 2001Transcranial colour Doppler ultrasonography (TCCD), being a non-invasive method is an invaluable source of information on cerebral haemodynamics. It is the blood flow disturbances that often lead to irreversible ischemic lesions, which can then be detected a posteriori with various imaging techniques.

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.

Ultrasonography and Doppler Techniques
2019Acute 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.

Penile Duplex Doppler Ultrasonography
2016The duplex Doppler ultrasound is a procedure to evaluate erectile hemodynamics. Doppler ultrasound is combined with an intracavernosal injection of vasoactive agents to evaluate penile blood flow. This test evaluates arterial inflow, as well as venous outflow.
