Use of Navigator Echoes for 4D-MRI

Overview

About this study

The general aim of this proposal is to evaluate new non-significant risk (NSR) MRI technology in a clinical setting, specifically the use of preclinical (non-FDA-approved) sequences (including but not limited to bSSFP, SSFSE) which have been modified from their standard counterparts to include interleaved 1D body navigator pulses.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

Volunteers:
- The volunteer population will be comprised of non-pregnant adults having age at least 18 years.
Patients:
- The patient population will be comprised of individuals who present with a cancer diagnosis requiring radiotherapy in the chest or abdominal region
- Patients must be at least 7 years of age.
- For each case, the non-FDA approved sequence(s) will only be prescribed if there is evidence that this new MRI technology may add value to the current standard of care (namely, evaluation of breathing motion for radiation planning using 4D-CT alone.) .
- Only those patients having received 4D-CT as part of routine treatment planning will be considered for this pilot study

Exclusion Criteria:

Volunteers:
- Pregnancy
- All exclusions associated with routine MRI safety screening apply.
- We will discourage persons who have previously experienced claustrophobia during MRI scans from enrolling.
Patients:
- Pregnancy
- All exclusions associated with routine MRI safety screening apply.
