An observational study in Tumors (Others), Viscera and Masses, sponsored by Cook Research Incorporated. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-08-28.
Sponsored by Cook Research Incorporated (part of Cook Group Incorporated) · Observational
The purpose of this study is to evaluate the safety and performance of the Cook® iMRI Needle. This is an investigational needle that physicians can use to gain access to a particular part of the body, take a small sample of tissue, or inject fluid into a particular part of the body.
10,818 studies on the registry are indexed under Neoplasms; 2,324 are open to participants now.
This study's enrollment of 10 is below the median of 200 across 2,638 observational studies indexed under Neoplasms.

Clinically appropriate patients who can willing participate in research.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Patient is suitable for inclusion in the study if the patient meets the following criteria:
A qualified physician directs the patient to have a procedure that requires a needle
for percutaneous access, aspiration, and/or injection during therapeutic or diagnostic interventional MRI-guided procedures
Exclusion Criteria:
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.
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.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Device: Percutaneous non-vascular access to anatomic structures
During MRI procedure, a Cook® iMRI Needle will be used instead of the standard of care needle.
Rate of successful needle introduction
Successful percutaneous needle introduction into the target anatomy.
Time frame: Duration of procedure (approximately 1 hour)
Ran from Jan 2026 to primary completion in Jun 2026, 4 months.
Of 148 industry-sponsored observational studies under Neoplasms, half reached primary completion within 47 months of starting (the median), counting those still running; a quarter within 29 and three quarters within 102. This study's 4 months is below that.
Counting every sponsor, half of 1,246 studies reached it within 58 months; a quarter within 24 and three quarters within 210.
Neoplasms covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.
