What this study is about
The purpose of this study is to see how well Photon Counting CT (PCCT) and ultrasound test results can find fat and scarring in the liver. They will be compared to MRI test results as the reference standard. Participants will get a regular CT scan on the PCCT scanner, plus a few extra pictures just for the study.
View original scientific description
The purpose of this study is to see how well Photon Counting CT (PCCT) and ultrasound test results can find fat and scarring in the liver. They will be compared to MRI test results as the reference standard. Participants will get a regular CT scan on the PCCT scanner, plus a few extra pictures just for the study. They will also get an MRI, either on the same day or a different day, whichever is preferred. Participants will get an ultrasound on the same day as the MRI. If they have not had a hematocrit blood test in the past 24 hours, they will also receive one on the day of the CT scan.

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.
