Ultrasound News and Research

RSS

Ultrasound is a procedure in which high-energy sound waves are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasonography.

Stroke risk rises in patients with sickle cell disease despite established guidelines

The incidence of stroke continues to increase for adults and children living with sickle cell disease (SCD) despite the Stroke Prevention Trial in Sickle Cell Anemia (STOP) establishing standards of care like transfusions and tests to measure blood flow in the brain for those deemed high-risk, according to a study published today in Blood.

New biomedical device offers hope for patients with chronic pain

Pain is a necessary biological signal, but a variety of conditions can cause those signals to go awry. For people with chronic pain, the root is often faulty signals emerging deep within the brain, giving false alarms about a wound that has since healed, a limb that has since been amputated, or other intricate, hard-to-explain scenarios.

Liver stiffness becomes crucial indicator for post-treatment hepatitis C risk assessment

Hepatitis C can be cured in almost all cases with modern medication. However, if advanced liver damage is already present at the time of cure, there is still a residual risk of liver cancer and complications of portal hypertension, such as abdominal fluid, bleeding from the digestive tract and confusion.
