To determine if high resolution MRI can detect early invasion of cartilage by laryngeal carcinoma, and to determine if high resolution MRI may be superior to conventional MRI imaging or CT imaging to detect cartilage invasion.
Head and Neck Cancers
Procedure: MRI scan
||Observational Model: Cohort
Time Perspective: Prospective
||High Resolution MRI in the Evaluation of Laryngeal Neoplasia
Primary Outcome Measures:
- Tumor stage as determined by histopathology in excised larynges. [ Time Frame: 4 to 6 weeks ] [ Designated as safety issue: No ]
- Estimate the precision of HRMRI in terms of cartilage invasion. [ Time Frame: 4 to 6 weeks ] [ Designated as safety issue: No ]
- Tumor stage as determined by HRMRI. [ Time Frame: 24 to 48 hours ] [ Designated as safety issue: No ]
- Estimate the precision of HRMRI in discriminating between edema and tumor in patients with prior radiotherapy or chemotherapy. [ Time Frame: 4 to 6 weeks ] [ Designated as safety issue: No ]

|Genders Eligible for Study:
|Accepts Healthy Volunteers:
Laryngeal cancer patients at Stanford University
- Patients with benign or malignant neoplasm of the larynx.
- Patients who have undergone prior surgery, radiation therapy, or chemotherapy for cancer of the laryngopharynx will be eligible to participate.
- Patients 18 years of age and older at time of evaluation, male and female, all ethnicities.
- Ability to understand and the willingness to sign a written informed consent document.
- Anatomic parameters which preclude scanning, such as limited range of neck motion, or inability to remain flat for at least 15 minutes.
- Patients with implanted devices (eg, defibrillator, pacemaker) that are a known contraindication to magnetic resonance imaging.
- Allergy to gadolinium contrast.
