Summary

This article details magnetic resonance (MR) imaging findings for osteomyelitis and septic arthritis. It provides criteria to distinguish these conditions from diabetic neuroarthropathy and avascular necrosis, including transient osteoporosis.

Area of Science:

  • Radiology
  • Orthopedics
  • Medical Imaging

Background:

  • Osteomyelitis and septic arthritis are serious bone and joint infections.
  • Diabetic neuroarthropathy and avascular necrosis present diagnostic challenges.
  • Magnetic resonance (MR) imaging is crucial for evaluating these conditions.

Purpose of the Study:

  • To outline MR imaging findings in osteomyelitis and septic arthritis.
  • To present criteria for differentiating osteomyelitis from diabetic neuroarthropathy.
  • To review MR imaging of avascular necrosis and differentiate it from transient osteoporosis.

Main Methods:

  • Review of MR imaging characteristics of bone and joint pathologies.
  • Analysis of imaging features distinguishing infectious from degenerative/metabolic conditions.
  • Comparison of MR imaging patterns for avascular necrosis and transient osteoporosis.

Main Results:

  • Specific MR imaging criteria are provided for diagnosing osteomyelitis and septic arthritis.
  • Distinct imaging features help differentiate these from diabetic neuroarthropathy.
  • MR imaging can differentiate avascular necrosis from transient osteoporosis based on edema patterns.

Conclusions:

  • MR imaging is a key modality for diagnosing bone and joint infections.
  • Differentiating infectious from non-infectious conditions like diabetic neuroarthropathy is feasible with MR imaging.
  • MR imaging aids in the differential diagnosis of avascular necrosis and transient osteoporosis.
