title: From tumor to trauma: etiologically deconstructing a unique differential diagnosis of musculoskeletal entities with high signal intensity on T1-weighted MRI.
abstract: OBJECTIVE
  This article reviews the neoplastic and nonneoplastic abnormalities of the musculoskeletal system that contain high signal intensity on T1-weighted MRI. The physical properties accounting for the increased signal intensity as well as the key clinical and imaging characteristics of each entity are discussed.
  
  
  CONCLUSIONS
  Recognition of high signal intensity within musculoskeletal lesions on T1-weighted MRI can limit the differential diagnosis and can also have important clinical implications.
