[Perfusion magnetic resonance imaging in the treatment of Perthes disease]

Area of Science:

• Orthopedics
• Pediatric Radiology
• Medical Imaging

Background:

• Perthes disease affects the femoral head, impacting long-term prognosis.
• Early detection of infarction distribution is crucial for treatment planning.
• Current diagnostic methods may lack detail in early disease stages.

Purpose of the Study:

• To review the utility of perfusion magnetic resonance imaging (pMRI) in assessing femoral head infarction in early Perthes disease.
• To evaluate pMRI's potential in guiding early surgical interventions for severe cases.
• To discuss the safety and unknowns of gadolinium contrast agents in pediatric patients.

Main Methods:

• Review of existing literature on perfusion magnetic resonance imaging (pMRI) in Perthes disease.
• Analysis of pMRI's ability to visualize infarction distribution in the femoral head.
• Consideration of clinical implications for pediatric orthopedic surgery.

Main Results:

• Perfusion magnetic resonance imaging (pMRI) provides detailed insight into femoral head infarction.
• The extent of head involvement visualized by pMRI correlates with long-term prognosis.
• pMRI may aid in identifying children who could benefit from early surgical treatment.

Conclusions:

• Perfusion magnetic resonance imaging (pMRI) is a valuable tool for evaluating early Perthes disease.
• pMRI can inform treatment decisions, particularly for severe cases requiring potential surgical intervention.
• While gadolinium contrast appears safe in the short term for children, long-term effects require further investigation.
