Researchers found ultrasound can accurately diagnose disc bulges and herniations, as well as detect soft tissue abnormalities. This non-invasive technique may help document clinical problems and reduce healthcare costs compared to MRI.
Researchers studied 10 patients with acute bacterial endocarditis and found that 80% continued to have microembolisms up to four weeks after treatment. Microembolisms can induce brain abscesses and lesions leading to stroke, and antibiotics alone may not be sufficient to prevent this risk.
Researchers use transcranial Doppler ultrasound to monitor brain activity as it happens, detecting increased blood flow during thinking and decreased flow when tasks are resolved. This technology has implications for treating mental illness, stroke recovery, and even lie detection.
A new ultrasound contrast agent, Levovist, has been used to treat an ischemic stroke in a German patient. The agent revealed the blocked artery and allowed doctors to dissolve the clot with thrombolytic rTPA, restoring blood flow to the brain within 40 minutes of admission.
Researchers from Germany used a prototype magnetic sensor workstation to reconstruct transcranial ultrasound in 3D, significantly improving the identification of intracranial arteries and accuracy of follow-up measurements. The new technology also enables easier comparison of relationships among brain arteries.
A new ultrasound technique using transcranial Doppler and duplex carotid ultrasound can accurately measure carotid artery blockages, reducing the need for cerebral angiography and associated risks. This method is a safer alternative for assessing blockage before deciding on surgery for stroke prevention.
A new study by German neurologists found that transcranial color-coded duplex sonography (TCDS) is 90% effective in distinguishing between ischemic and hemorrhagic strokes under emergency treatment conditions. TCDS can accurately diagnose stroke type in most cases, making it a fast and reliable option for acute stroke treatment.
A new ultrasound technique has been developed to improve food inspection by spotting defects as small as 10 microns in size, which is one-fifth the diameter of a human hair. The technology allows for the non-destructive detection of voids, air, water, or protein strands in plastic-sealed containers.
Young physicians who undergo formal training in ultrasound testing on pregnant women perform better than those without such training, according to a Johns Hopkins study. The formal training program includes a checklist of sonographic skills and evaluates residents' progress through practical exams.
The new sonochemical synthesis technique creates highly magnetic metal powders with clusters of a few hundred atoms, exhibiting superparamagnetic behavior. These powders have the potential to be used in various applications including information storage, audio reproduction, and magnetic sealing.
The UW-Siemens image processor enables the creation of multiple diagnostic applications, increasing clinical efficiency. It allows for real-time panoramic imaging of internal organs and their surroundings, revolutionizing diagnosis and treatment.
Researchers have invented a new digitally encoded plastic transparency to test the accuracy of ultrasound scanners. The new phantom is more accurate and works faster than current phantoms, which are cumbersome hand-built blocks made of various tissue-mimicking materials.
The new technology uses parallel computing to analyze reflected sound waves, creating three-dimensional images quickly enough for clinicians to view a whole human heart as it beats. The system also enables doctors to electronically dissect and display selected slices of medical interest on a computer screen.
