Study summary

Cancer and cardiovascular diseases are among the leading causes of morbidity and mortality worldwide. Advanced imaging techniques such as 4D magnetic resonance imaging (MRI) enable quantitative assessment of hemodynamic and functional parameters beyond conventional imaging. The aim of this study is to evaluate the association between 4D MRI derived parameters and the occurrence, severity, and prognosis of major chronic diseases, and to explore their potential role as imaging biomarkers.

Read the detailed description

This is a single-center, prospective, observational registry study conducted at Ulsan University Hospital. The study will enroll 1,000 adult patients (≥ 19 years) undergoing cardiac MRI as part of routine clinical care in Korea.

Participants will undergo an additional 4D MRI sequence during the same imaging session, which does not affect clinical decision-making or patient management.

The primary objective of this study is to evaluate the association between quantitative imaging parameters derived from 4D MRI and the occurrence, severity, and prognosis of major chronic diseases.

Study population

Adult patients aged 19 years and older undergoing clinically indicated cardiac MRI at Ulsan University Hospital (Ulsan, South Korea) will be included in the study population. Individuals who provide written informed consent and undergo an additional 4D MRI sequence during the same imaging session will be enrolled in this prospective observational registry.

Inclusion criteria

  • Adults aged 19 years and older undergoing clinically indicated Cardiac MRI at Ulsan University Hospital
  • Participants who undergo an additional 4D MRI sequence during the same imaging session
  • Participants who are able to understand the study and provide written

Exclusion criteria

Exclusion Criteria:

  • Individuals aged \< 19 years
  • Individuals with cognitive impairment or communication difficulties unable to provide
  • Poor-quality MRI images that are not suitable for analysis
  • Individuals deemed inappropriate for study participation by the investigator
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2026 (actual). Primary completion is estimated for Feb 2036, 115 months after the start.

Of 580 non-industry observational studies under Cardiovascular Diseases, half reached primary completion within 70 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 196. This study's planned 115 months is above that.

Counting every sponsor, half of 664 studies reached it within 61 months; a quarter within 24 and three quarters within 192.

Cardiovascular Diseases covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 23, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
