Comparative Study between Multi-slice Computed Tomographic Arthrography and Arthroscopy in the Evaluation of Rotator...

Area of Science:

• Orthopedics
• Radiology
• Diagnostic Imaging

Background:

• Rotator cuff tears are a common cause of shoulder pain and dysfunction.
• Magnetic resonance imaging (MRI) is the gold standard for diagnosing rotator cuff tears, but contraindications exist.
• Alternative imaging modalities are needed when MRI is not possible.

Purpose of the Study:

• To compare the diagnostic accuracy of multi-slice computed tomographic arthrography (MSCTa) with arthroscopy for rotator cuff tears.
• To evaluate anatomical alterations in rotator cuff tears using MSCTa.
• To correlate MSCTa findings with gold standard arthroscopy findings.

Main Methods:

• A prospective, comparative diagnostic accuracy study.
• Inclusion of patients aged 40-70 with rotator cuff tears and need for arthroscopy.
• Patients with MRI contraindications were included.
• MSCTa was performed, followed by shoulder arthroscopy for all participants.

Main Results:

• The study determined sensitivity, specificity, accuracy, positive predictive value, negative predictive value, and Kappa coefficient.
• Quantitative analysis compared MSCTa findings with arthroscopic results.
• Detailed correlation of imaging findings with surgical outcomes was performed.

Conclusions:

• Multi-slice computed tomographic arthrography is a viable imaging option for diagnosing rotator cuff tears.
• MSCTa demonstrates diagnostic capability when MRI is contraindicated.
• This technique aids in evaluating anatomical alterations associated with rotator cuff pathology.
