MAGNETIC RESONANCE IMAGING CHARACTERISTICS AND ADDED VALUES OF X-RAY AND ULTRASONOGRAPHY IN DIAGNOSIS OF ROTATOR CUFF LESIONS

Abstract

Purpose: To study magnetic resonance imaging characteristics and the added values of x-ray and ultrasonography in diagnosis of rotator cuff lesions. Material and method: 45 patients with clinical suspected rotator cuff lesions were recruited from may 2018 to august 2019 at Hue University of Medicine and Pharmacy Hospital. Patients undergone X-ray, Ultrasonography, and Mri of shoulder joint. The X ray and sonographic features were compared to MRI results to evaluate the added value of X-ray and ultrasonography in diagnosing rotator cuff lesions. Results: Ultrasound detected supraspinatus tear in 86.7%, tendonitiss in 40% and tenosynovitis in 8.9% of cases. X-ray detected suggestive features of supraspinatus tendon injuries in 88.9% of cases. Patients with two or more suggestive features was 46.7% with greater tuberosity sclerosis and calcification at the attachment site of tendon were the most common findings. The relationship between diagnosis of supraspinatus tendon tear, tendonitis and tenosynovitis on ultrasound with the number of suggested features on X-rays was 0.02, 0.564, 0.89. Conclusion: X-ray have supportive value for ultrasound in diagnosis of supraspinatus tendon tear.
