NCT03759704

Brief Summary

Investigators will determine whether MRSI using hyperpolarized \[1-13C\]pyruvate provide useful information of tumor malignancy in MRI-indeterminate cases. Metabolite maps of hyperpolarized \[1-13C\]lactate and H13CO3- produced from hyperpolarized \[1-13C\]pyruvate will be compared to the biopsy results of MRI-indeterminate patients and the 13C-maps of age-matched healthy subjects.

Study Arms (1)

Hyperpolarized 13CPyruvate and gadolinium

Injection with hyperpolarized 13CPyruvate followed by gadolinium during MRSI.

Drug: Hyperpolarized 13CPyruvate

Interventions

Sampling MethodProbability Sample
Study Population

Eligible study participants will be identified by referring physicians from a UT Southwestern Clinic. A treating physician will discuss the potential research opportunity with their patient to determine interest in study participation.

You may qualify if:

  • SARCOMA patients:
  • \- MRI indeterminate solid enhancing lesion in the pelvis or extremity.
  • ALL subjects:
  • Age 18 through 100 years.
  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
  • Ability to understand and the willingness to sign a written informed consent.
  • All races and ethnicities will be included; subjects must be able to read and speak the English or Spanish language.

You may not qualify if:

  • SARCOMA patients:
  • Subjects who have had radiotherapy to the indeterminate lesion.
  • ALL subjects:
  • Subjects who have had chemotherapy within 4 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
  • Subjects may not be receiving any other investigational agents.
  • Any contraindication per MRI Screening form including implants contraindicated at 3T, pacemakers, implantable Cardioverter Defibrillator (ICD), claustrophobia.
  • Metallic foreign bodies in the field of view which may interfere with MRI acquisitions.
  • Since each subject is receiving a gadolinium based contrast agent intravenously, additional contraindications would include: eGFR ≤ 30 mL/min/1.73m2, sickle cell disease, or hemolytic anemia.
  • Uncontrolled psychiatric illness/social situations that would limit compliance with study requirements.
  • Subjects must not be pregnant or nursing due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants.
