Femoral Artery Doppler Ultrasound is more Accurate than Manual Palpation for Pulse Detection in Cardiac Arrest.

Resuscitation, 2022
OBJECTIVES Our primary objective was to assess the accuracy of Doppler ultrasound versus manual palpation in detecting any pulse with an arterial line waveform in cardiac arrest. Secondarily, we sought to determine whether peak systolic velocity (PSV) on

Bowel Ultrasound State of the Art: Grayscale and Doppler Ultrasound, Contrast Enhancement, and Elastography in Crohn Disease

Journal of ultrasound in medicine, 2019
Bowel ultrasound (US) is accurate for assessing bowel inflammation and complications in Crohn disease. Additionally, contrast‐enhanced US provides a quantitative, objective measurement of inflammatory activity in inflammatory bowel disease, and shear ...

Renovascular disease: Doppler ultrasound

Seminars in Ultrasound, CT and MRI, 1997
Color Doppler ultrasound (CDUS) seems to be an effective imaging technique for the diagnosis of renal vascular diseases. It is already the modality of choice for the detection of acute renal vein thrombosis and nonocclusive intrarenal vascular disorders including iatrogenic arteriovenous fistula and false aneurysm, particularly in patients with ...

Transcranial Doppler ultrasound

Neurology, 1990
Summary and critique. Advantages of method. TCD is a noninvasive test effective in monitoring blood velocities in large intracranial arteries. It uses small, potentially portable, relatively inexpensive equipment. The test can be repeated and therefore allows the detection of changes over time and after various physiologic studies or pharmacologie ...

[Doppler ultrasound study of breast tumors using color Doppler ultrasound, duplex ultrasound and the CW Doppler ultrasound].

Zentralblatt fur Gynakologie, 1992
The preoperative examinations by doppler-sonography of 83 patients with tumors of the breast are presented. The examinations are done with newest technique: duplex-sonography in slow-flow-technique (AI 3200, Dornier); colour-sonography in MEM-technique (AI 5200, Dornier) and synchronical colour-doppler++ (Quantum 2000, Siemens) and CW-doppler ...

Intrapartum Doppler ultrasound

Minerva Ginecologica, 2020
Intrapartum hypoxic events most commonly occur in low-risk pregnancies with appropriately grown fetuses. Continuous intrapartum monitoring by means of cardiotocography has not demonstrated a reduction in the frequency of adverse perinatal outcome but has been linked with an increase in the caesarean section rate, particularly among women considered at ...

Doppler Ultrasound in Mice

Echocardiography, 2007
Color, power, spectral, and tissue Doppler have been applied to mice. Due to the noninvasive nature of the technique, serial intraindividual Doppler measurements of cardiovascular function are feasible in wild‐type and genetically altered mice before and after microsurgical procedures or to follow age‐related changes.

Doppler Ultrasound in Obstetrics

JAMA: The Journal of the American Medical Association, 1971
Since its first description in 1964, Doppler-principle ultrasound has been used for detection of fetal life, placental localization, and more recently detection of multiple pregnancies and fetal heart monitoring. Techniques and methods of interpretation as applied to 521 patients gave the following accuracy in each determined: detection of fetal life ...

Doppler ultrasound - basics revisited

British Journal of Nursing, 2006
Palpation of pedal pulses alone is known to be an unreliable indicator for the presence of arterial disease. Using portable Doppler ultrasound to measure the resting ankle brachial pressure index is superior to palpation of peripheral pulses as an assessment of the adequacy of the arterial supply in the lower limb. Revisiting basics, this article aims
