Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Laryngeal Neoplasms Head and Neck Cancers Larynx Cancer Procedure: MRI scan Early Phase 1

Detailed Description:

The purpose of this study is to use a new MRI imaging coil developed for enhancing structures made of cartilage to determine if the device can produce improved images of the human larynx. In addition, if enhanced images can be obtained, a further purpose will be to determine if, in patients with laryngeal cancer, whether or not early invasion of cartilage can be detected. Patients with laryngeal cancer will be asked to undergone an MRI scan using this new image-enhancing coil to see if cartilage invasion can be detected. Patients will be followed during and after treatment to determine their ultimate response to treatment. No additional MRI scans for the purposes of this protocol will be performed other than the initial pretreatment scan.

We hope to determine if this new MRI imaging device can detect early cancer invasion of the laryngeal cartilages in patients with laryngeal cancer. Since this modality has never been attempted before on the human larynx, we are simply looking for the presence or absence of cartilage destruction. Both conventional CT and conventional MRI are poor at recongnizing this finding. High resolution MRI may allow the detection of this finding or it may not - detection of this finding is the endpoint.

Primary Outcome Measures :
  1. Tumor stage as determined by HRMRI. [ Time Frame: 24 to 48 hours ]
    Radiologic tumor stage

Secondary Outcome Measures :
  1. Estimate the precision of HRMRI in discriminating between edema and tumor in patients with prior radiotherapy or chemotherapy. [ Time Frame: 4 to 6 weeks ]
    Comparison of true tumor dimension as predicted by HRMRI versus true tumor size as shown on final histopathology

  2. Tumor stage as determined by histopathology in excised larynges. [ Time Frame: 4 to 6 weeks ]
    Pathological tumor stage
