MR imaging in inflicted brain injury.

Area of Science:

• Neuroradiology
• Pediatric Radiology
• Forensic Radiology

Background:

• Inflicted brain injury (IBI) is a serious concern, particularly in pediatric cases.
• Accurate diagnosis and assessment of IBI are critical for patient management and legal proceedings.
• Conventional imaging modalities may have limitations in detecting subtle injuries or determining injury age.

Purpose of the Study:

• To evaluate the role of Magnetic Resonance (MR) imaging in the routine workup of suspected inflicted brain injury.
• To highlight the importance of diffusion-weighted MR imaging in assessing acute hypoxic-ischemic brain injury.
• To explore the utility of MR imaging in dating intracranial hemorrhages.

Main Methods:

• Review of current literature and clinical guidelines regarding MR imaging in suspected IBI.
• Emphasis on the application and interpretation of diffusion-weighted imaging (DWI) sequences.
• Discussion of MR imaging findings related to intracranial hemorrhages.

Main Results:

• MR imaging should be integrated into the standard diagnostic process for suspected IBI.
• Diffusion-weighted MR imaging is highly sensitive for detecting acute hypoxic-ischemic brain injury, defining lesion extent, and providing prognostic information.
• While MR imaging can assist in dating intracranial hemorrhages, precise timing remains challenging.

Conclusions:

• Routine use of MR imaging, particularly DWI, is recommended for evaluating suspected inflicted brain injury.
• DWI is invaluable for characterizing acute brain injury and its potential outcomes.
• Accurate temporal characterization of hemorrhages with MR imaging is often limited.
