Diagnostic Imaging of Vascular Malformations Using MSOT and ULM
This study is investigating new imaging methods, called Multispectral Optoacoustic Tomography (MSOT) and Ultrasound Localization Microscopy (ULM), to see how well they can diagnose a group of conditions known as vascular malformations. These are unusual growths of blood or lymphatic vessels, like arteriovenous, venous, or lymphatic malformations. The goal is to improve how doctors identify these conditions and plan treatment. MSOT can measure oxygen levels, which helps tell different types of malformations apart. ULM uses tiny bubbles to track blood flow. We hope these new scans can offer a clearer picture than traditional methods like X-rays (CT scans) or MRI, and potentially reduce the need for tests that use radiation or are more complicated.
At a glance
What is this study about?
This study is all about finding better ways to diagnose certain types of unusual growths called vascular malformations. Imagine your blood vessels and lymphatic vessels (which are part of your body's drainage system) not forming quite right. This can lead to different kinds of malformations, such as those involving arteries and veins (arteriovenous), just veins (venous), or just lymphatic vessels (lymphatic). Right now, doctors often use scans like ultrasound, CT scans (which use X-rays), or MRI scans to figure out what's going on.
We're testing two exciting new scanning techniques: Multispectral Optoacoustic Tomography (MSOT) and Ultrasound Localization Microscopy (ULM). MSOT is pretty clever – it can look at how much oxygen is in the blood or tissues. This is important because blood in arteries has a lot of oxygen, blood in veins has less, and lymphatic fluid has none. By measuring these oxygen levels, MSOT might help us tell the different types of malformations apart. ULM works by tracking tiny, harmless bubbles in your bloodstream to see how blood is flowing. This could also give us clues about which type of malformation is present.
The main aim is to see if MSOT and ULM can give doctors a more precise picture of these malformations. This added detail could help them plan the best treatment for each person. A big benefit is that these new methods don't use X-rays, which means less radiation exposure compared to CT scans. They could also be simpler and less time-consuming than MRI scans, potentially making diagnosis easier and safer for patients in the future.
Key takeaways
- New ways to scan vascular malformations are being tested.
- MSOT and ULM are non-invasive techniques, meaning no needles or surgery.
- The goal is to improve diagnosis and treatment planning.
- Could reduce the need for X-rays (CT scans) in the future.
- Only for adults (18+ years old) who already have a vascular malformation diagnosis.
Who may be eligible?
To join this study, you need to be an adult, aged 18 years or older, and have already been diagnosed with a vascular malformation. This includes arteriovenous, venous, or lymphatic malformations. It's really important that you understand what the study involves and are happy to give your written permission to take part.
You cannot join the study if you are under 18 years old. Also, if there are any safety concerns that the study doctors have about your physical or mental health that might make it unsafe for you to participate, or affect the quality of the information collected, then you wouldn't be able to join. Lastly, if you haven't had any scans to confirm your vascular malformation, or don't have any planned, then this study might not be right for you.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Have you been diagnosed with a vascular malformation (e.g., arteriovenous, venous, or lymphatic)?
- Have you had scans to confirm your diagnosis, or do you have them planned?
- Are you able to understand the study and give your written permission to take part?
What does participation involve?
The study does not specify particular visits, assessments, medication, or follow-up duration. However, if you join, you would undergo the new scanning techniques being tested: Multispectral Optoacoustic Tomography (MSOT) and Ultrasound Localization Microscopy (ULM). These would be in addition to any standard scans you might already be having for your vascular malformation.

Common questions
What are vascular malformations?
They are unusual growths or tangles of blood vessels (like arteries or veins) or lymphatic vessels that didn't form perfectly.
What are MSOT and ULM?
They are new, non-invasive scanning methods. MSOT checks oxygen levels in tissue, and ULM uses tiny bubbles to watch blood flow.
Will these new scans replace my regular doctor's visits?
No, these are research scans to see if they can help doctors in the future. They would be used alongside your usual medical care.
Do the scans hurt?
The study describes them as 'non-invasive,' meaning they don't involve cutting or needles. They are generally considered comfortable, but full details would be explained before you decide to join.
Who can join this study?
Adults aged 18 or over who have a confirmed vascular malformation and are willing to give their consent to participate.
