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.
