Ultrasound Technique for Spinal Tap Assessment
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new ultrasound technique to measure pressure inside the skull for individuals with conditions like idiopathic intracranial hypertension, which causes increased brain pressure. The technique uses tiny microbubbles (perflutren lipid microsphere, a type of contrast agent) and sound waves to estimate pressure without an invasive spinal tap. If successful, this could simplify and improve the safety of diagnosing and monitoring these conditions. Ideal participants have conditions requiring a spinal tap to check brain pressure and are not allergic to certain contrast agents. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this ultrasound technique is safe for spinal tap assessment?
Previous studies have safely used a substance called perflutren lipid microsphere to enhance ultrasound images. Research shows it works effectively and is generally safe for adults, including older adults. Most side effects are mild, such as headaches or nausea, and serious issues are rare. Thus, the treatment is considered safe for people.12345
Why are researchers excited about this trial?
Researchers are excited about this trial because it explores a new ultrasound technique for assessing spinal fluid pressure, potentially improving the accuracy of diagnosing conditions related to intracranial pressure (ICP). Unlike traditional spinal taps, which can be invasive and uncomfortable, this method uses perflutren lipid microsphere as a contrast agent, making the procedure less invasive and possibly safer. This innovation could lead to quicker, more precise diagnostics, sparing patients the discomfort and risks associated with traditional lumbar punctures.
What evidence suggests that the SHAPE technique is effective for monitoring intracranial pressure?
Research has shown that the SHAPE technique, which participants in this trial will experience, uses tiny bubbles called perflutren lipid microspheres and holds promise for measuring pressure inside the skull. This method employs ultrasound to activate these bubbles, enhancing image quality. Studies have found that it can estimate pressures in various body parts, such as the heart and other tissues, by observing bubble behavior. The bubbles help create clear images sensitive to pressure changes, crucial for diagnosing conditions like idiopathic intracranial hypertension, which involves high pressure around the brain. This technique could provide a noninvasive way to monitor brain pressure, potentially leading to better patient outcomes.678910
