Transcranial Doppler Ultrasound in Critically Ill Patients With Cardiovascular Comorbidities

Transcranial Doppler ultrasound is bedside tool use to assess cerebral blood perfusion in critically ill patients. We sought to conduct a prospective, single centre study aiming to determi...

Reproducibility Study of Transcranial Doppler

Hardening of the neck vessels (carotid arteries) caused by fatty deposits called 'plaques' is a common cause of strokes. Over time plaques can burst or may lead to a severe narrowing (sten...

Identification of C7; Evaluations of 2 Sonographic Methods Using a Transverse and a Sagittal Scan.

To determine the accuracy of two techniques (transverse scan and sagittal scan) using ultrasonography to identify C7 spinous process compare to the fluoroscope (standard technique)

Three Dimensional (3D) Ultrasound in Predicting Response to Breast Cancer Therapies

The purpose of this study is to determine how well changes can be determined in malignant masses from ultrasound scans.

Impact on Patient Satisfaction About Realization of Ultrasound Dopplers at the Bed

Organisation and logistic about realisation of vascular doppler ultrasound is something very eclectic . Need to shift patient from their bed , long waiting time and the effect on the hospi...

Rapid Assessment of the Neonate With Sonography (RANS) Scan.

The use of point-of-care sonography in clinical settings such as emergency medicine and intensive care units has increased, but adoption in neonatology has been slow. Unlike the focused assessment wit...

Liver transplantation for fulminant hepatitis due to yellow fever.

A previously healthy 27-year-old female had 3 days of fever (40°C), headache, and myalgia. She had not been previously vaccinated for YF. Initial workup revealed 2,150 leukocytes/mm , 83,000 platelet...

The Value of Detailed First-Trimester Ultrasound Anomaly Scan for the Detection of Chromosomal Abnormalities.

 To evaluate the performance of first-trimester ultrasound screening involving a detailed anomaly scan for the detection of trisomy 18, trisomy 13, triploidy, Turner syndrome and trisomy 21.

Acute Acalculous Cholecystitis in the Setting of Negative Ultrasound and Computed Tomography Scan of the Abdomen.

Acute acalculous cholecystitis (AAC) is most commonly seen after surgery in critically ill patients. Early diagnosis and treatment is the key in the management of AAC. Ultrasound is the commonly used...

Prenatal diagnosis of Norrie disease based on ultrasound scan findings.

Norrie disease (ND; OMIM: 310600) is a rare, X-linked, recessive genetic disease caused by mutations in the NDP gene and characterized by congenital blindness due to bilateral degenerative changes in ...

Medical and Biotech [MESH] Definitions

A method of differentiating individuals based on the analysis of qualitative or quantitative biological traits or patterns. This process which has applications in forensics and identity theft prevention includes DNA profiles or DNA fingerprints, hand fingerprints, automated facial recognition, iris scan, hand geometry, retinal scan, vascular patterns, automated voice pattern recognition, and ultrasound of fingers.

Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow. (Stedman, 25th ed)

A non-invasive technique using ultrasound for the measurement of cerebrovascular hemodynamics, particularly cerebral blood flow velocity and cerebral collateral flow. With a high-intensity, low-frequency pulse probe, the intracranial arteries may be studied transtemporally, transorbitally, or from below the foramen magnum.

The use of combination of imaging techniques or platforms (e.g., MRI SCAN and PET SCAN) encompassing aspects of anatomical, functional, or molecular imaging methods.

Ultrasonography applying the Doppler effect combined with real-time imaging. The real-time image is created by rapid movement of the ultrasound beam. A powerful advantage of this technique is the ability to estimate the velocity of flow from the Doppler shift frequency.
