4D-MRI for Precision Medicine in Cancer Treatment

This study is developing a new way to create detailed images of the lungs and liver using a technique called four-dimensional magnetic resonance imaging (4D-MRI). This imaging method creates 3D movies of your chest and abdomen as you breathe, helping doctors see how tumors move. The goal is to improve radiation therapy for lung and liver cancer by providing more precise information about tumor size, shape, and location. Researchers will measure the quality of these images and how accurately they show movement in healthy volunteers and patients with liver or lung cancer. You may be eligible if you are an adult with lung or liver cancer that is less than 7 cm and you are scheduled for radiation therapy.

Study design
This is an observational study aiming to enroll 100 participants, including healthy volunteers and cancer patients.
What's involved
You would undergo a single imaging session lasting up to 2 hours.
Compensation
Not stated in the trial record.
Follow-up
Image quality and movement errors are measured during a single imaging session, lasting up to 2 hours.

Eligibility criteria

Inclusion

Patient is 21 or older
Patient has primary or metastatic tumor(s) in the lungs or the liver
Diameter of the tumor(s) is less than 7 cm
Patient will receive radiation therapy (ordered by the treating Radiation Oncologist) as part of their treatment regimen
Patient will undergo a planning CT scan with tumor motion assessment (planning 4D-CT ordered by the treating Radiation Oncologist) as part of their treatment regimen
Patient has signed informed consent and is willing to comply with the 4D-MRI imaging protocol
Subject is 18 or older
Subject has signed informed consent and is willing to comply with the 4D-MRI imaging protocol

Exclusion

Any condition for which a MRI procedure is contraindicated including presence of metallic material in the body, such as pacemakers, non- MRI compatible surgical clips, shrapnel, etc.
Subjects who have difficulty lying flat on their back for extended periods of time
Patients with any serious/poorly controlled medical or psychological conditions that would complicate protocol compliance
Too large to adequately fit in the magnet bore or RF coils
Claustrophobia
Females who are pregnant or lactating
Presence of active or chronic infection
  • Image quality metrics in healthy volunteerssingle imaging session, lasting up to 2 hours

    General 4D-MRI image quality will be assessed based on signal-to-noise ratio, number of distinct images per breathing cycle, total necessary imaging time, and image quality index.

  • Image quality metrics in cancer patientssingle imaging session, lasting up to 2 hours

    We hypothesize that our ultra-quality 4D-MRI methodology will outperform 4D-CT for motion management of radiotherapy in the lungs and the liver. We will test this hypothesis by comparing image quality based on tumor volume consistency, number of trackable landmarks, motion measurement accuracy, and image quality index.

  • DVF errors in healthy volunteers and cancer patientssingle imaging session, lasting up to 2 hours

    We hypothesize that our motion modeling method based on 4D-MRI will outperform current DIR algorithms for respiratory motion estimation. We will test this hypothesis by comparing our method to five existing DIR algorithms, based on the magnitude error (Em) and the angular error (Ea) of the calculated deformation vector field (DVF).
