Modulating Escape Using Focused Ultrasound
What this study is about
This is a study to find out if a cutting-edge technology called transcranial focused ultrasound (tFUS) can be used to treat how people with anxiety or related concerns cope with emotional situations. tFUS is a brain stimulation technology that causes temporary changes in the activity of deep brain areas without a need for any surgery or other permanent or invasive procedures.
View original scientific description
This is a study to find out if a cutting-edge technology called transcranial focused ultrasound (tFUS) can be used to treat how people with anxiety or related concerns cope with emotional situations. tFUS is a brain stimulation technology that causes temporary changes in the activity of deep brain areas without a need for any surgery or other permanent or invasive procedures. This study is recruiting participants who recently started treatment for anxiety or a related concern to come in for 3 visits at the Medical University of South Carolina. At the first visit, participants will do interviews and surveys asking about anxiety and related concerns, and they do tasks where they respond to emotional pictures while brain activity is measured using magnetic resonance imaging (MRI). At the next two visits, participants again do a task where they see and react to emotional images, and this time the task is done once before and again once after receiving tFUS that either actively causes temporary changes (lasting for about an hour) in a targeted brain area or is not active (no changes elicited). At each tFUS visit, responses are measured with sensors worn on the hand, arms, face, and head (these visits do not involve MRI). Each visit in this study is expected to last between 2 - 3 hours. This study is not a treatment study, but it could help improve treatment in the future. Participants in this study are paid for their time.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
