New York, New YorkAges 21–55 - NCT06793774Recruiting
Using CT scans and AI to evaluate heart artery risk
This study uses a CT scan of your heart (CCTA) and advanced computer analysis to see how well it can predict heart risks compared to detailed inside-look tests (IVUS, OCT, NIRS). If you have chest pain and have had certain heart scans, this trial may help doctors understand your condition better.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06793787Recruiting
AI and advanced imaging to guide treatment of borderline heart blockages
This study uses advanced CT scans and a special camera (OCT) to look at borderline blockages in heart arteries more closely. It aims to see if artificial intelligence can help decide which blockages need a stent and which can be treated with medicine alone.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06797661Recruiting
Brain lesion blood flow study before surgery
This study looks at how blood flow in the brain changes when there is a mass that can be removed with surgery. You would join before any treatment, which helps doctors understand the link between the brain lesion and blood vessel function.
BrusselsAges 18–90 - NCT06803134Recruiting
Retraining neck control for better function in cervical radiculopathy
This trial tests a specific neck movement retraining program to improve joint awareness and daily function in people with chronic cervical radiculopathy (nerve irritation in the neck). It may help if you have had neck pain that goes into your arm for at least 3 months.
DamiettaAges 40–55 - NCT06806397Recruiting
Brain imaging study of arm weakness after stroke
This study uses a light-based brain scanner (fNIRS) to understand how stroke affects arm movement. It may help find new ways to improve rehab.
MoscowAges 35–70 - NCT06811324RecruitingPhase 2
Tirzepatide for muscle and vessel health in older adults
This study tests if the drug tirzepatide can improve muscle and blood vessel health in older adults with obesity. You may be eligible if you are 50 or older, have a BMI between 30 and 40, and do not have diabetes.
San Antonio, TexasAges 50 years+ - NCT06811519Recruiting
AI predicts heart function from ultrasound and body scans
This study uses artificial intelligence to predict how well your heart is pumping by looking at your heart ultrasound results and body composition (like body fat and muscle). The goal is to see if adding body composition data makes the AI predictions more accurate.
Yongin, Gyeonggi-doAges 20 years+ - NCT06815601Recruiting
Brain stimulation for better limb function after spinal cord injury
This study tests if a non-invasive brain stimulation method can improve arm and hand function in people with spinal cord injury, as well as in healthy individuals. The goal is to find a safe and effective way to boost recovery.
Buffalo, New YorkAges 18–75 - NCT06819475Recruiting
Muscle health study for childhood leukemia survivors
This study uses imaging to look at how well the mitochondria (the tiny power plants inside your muscle cells) are working. It compares survivors of childhood leukemia who have low muscle mass to healthy volunteers, to understand muscle health and find ways to help.
