To evaluate the diagnostic value of direct CT arthrography (CTA) using 16 slice MDCT in the assessment of SLAP lesions with arthroscopic correlation.

CTA was performed in 155 patients with shoulder pain and/or instability between April 2004 and March 2006. CTA images were evaluated prospectively for the presence and type of SLAP lesions. All patients subsequently underwent arthroscopic surgery. Findings on arthroscopy were compared with CTA findings. The sensitivity (SN), specificity (SP), positive (PPV) and negative predictive values (NPV), and accuracy (AC) for the diagnosis of SLAP lesions were calculated.

SLAP was diagnosed in 79 patients on CTA. The distribution of type of SLAP lesions were as follows: 4 type I, 46 type II, 3 type III, 1 type IV, 16 type V, 2 type VI, 2 type VII, 3 type VIII, 2 type IX. SLAP lesions were diagnosed in 68 patients on arthroscopy. The distribution of type of SLAP lesions on arthroscopy were as follows: 3 type I, 42 type II, 2 type III, no type IV, 15 type V, 2 type VI, 2 type VII, 2 type VIII, no type IX. The overall SN of CTA for SLAP lesions was 86%, SP 90%, PPV 90%, NPV 86%, AC 88% compared with arthroscopic results.

Direct CTA using 16-slice MDCT may be a reliable diagnostic modality for patients with suspected SLAP lesions.
