text: Turbo inversion recovery magnitude (TIRM) measures only the magnitude of a turbo spin echo after a preceding inversion pulse, thus is phase insensitive.
  TIRM is superior in the assessment of osteomyelitis and in suspected head and neck cancer. Osteomyelitis appears as high intensity areas. In head and neck cancers, TIRM has been found to both give high signal in tumor mass, as well as low degree of overestimation of tumor size by reactive inflammatory changes in the surrounding tissues.
