Multislice spiral computed tomography imaging in evaluating hemophilic arthropathy

Area of Science:

• Orthopedics
• Radiology
• Hematology

Background:

• Hemophilic arthropathy (HA) evaluation is crucial for patient management.
• Magnetic resonance imaging (MRI) is a standard diagnostic tool but can be costly and inaccessible.
• Alternative imaging modalities are needed for HA assessment.

Purpose of the Study:

• To assess the diagnostic value of multislice spiral computed tomography (MSCT) in evaluating hemophilic arthropathy (HA).
• To compare MSCT findings with MRI in patients with HA.
• To determine the feasibility of MSCT as an alternative imaging technique for HA.

Main Methods:

• Prospective study of 38 patients (73 joints) with HA.
• Comparison of X-ray, CT, and MRI findings within 48 hours.
• Quantification of CT and MRI scores using established standards, with CT using Pettersson score for joint space narrowing.

Main Results:

• MSCT and MRI showed high consistency (kappa > 0.81) for moderate/severe effusion, synovial hypertrophy, hemosiderin deposition, bone erosion, and cystic changes.
• MRI was superior for mild effusion and mild synovial hypertrophy/hemosiderin deposition (P < 0.05).
• High consistency (kappa = 0.774, P < 0.05) was observed between CT-based Pettersson scores and MRI-based cartilage injury scores.

Conclusions:

• MSCT provides generally consistent results with MRI for evaluating hemophilic arthropathy.
• MSCT can be utilized as a valuable alternative imaging modality for HA, particularly when MRI is not accessible.
• The findings support the use of MSCT for routine HA assessment in clinical practice.
