[Roentgen diagnosis and computerized tomography in inflammatory rheumatic diseases. Methods with a future?]

Area of Science:

• Radiology
• Rheumatology
• Medical Imaging

Background:

• Plain-film radiography is a fundamental tool for evaluating inflammatory rheumatic diseases.
• It assesses osseous destruction, inflammatory activity, and soft tissue changes like swelling and tenosynovitis.
• These findings can indicate an acute clinical phase.

Purpose of the Study:

• To highlight the complementary roles of plain-film radiography and high-resolution computed tomography (CT) in diagnosing and managing inflammatory rheumatic diseases.
• To detail the specific applications and diagnostic capabilities of each imaging modality.

Main Methods:

• Review of the diagnostic utility of plain-film radiography in inflammatory rheumatic conditions.
• Evaluation of high-resolution computed tomography for assessing cortical bone structures and specific anatomical regions.
• Comparison of imaging findings for sacroiliac joints, sternoclavicular joints, and craniocervical junction.

Main Results:

• Plain-film radiography effectively demonstrates inflammatory osseous destruction and soft tissue abnormalities.
• High-resolution CT provides detailed visualization of cortical bone, complementing other imaging techniques.
• CT offers high specificity for axial skeleton evaluation, aiding definitive diagnosis and surgical planning.

Conclusions:

• Plain-film radiography and CT are essential, complementary imaging modalities for inflammatory rheumatic diseases.
• CT is particularly valuable for detailed assessment of the axial skeleton and specific joints.
• Combined use optimizes diagnosis, disease activity assessment, and treatment planning.
