The sensitivity and specificity of (SSSEP-DWI) will also be calculated. Patients and methods: Sixty-eight acute vertebral compression fractures in 41 patients were imaged using conventional MRI, fat suppressed contrast enhanced T1WI and DW sequence on a 1.5 T MR machine. Quantitative assessment of the abnormal signal intensity was done by measuring apparent diffusion coefficients (ADCs). Also, the areas of abnormal signal intensity were compared to adjacent normal marrow. Results: We had 38 benign fractures, and 30 malignant fractures. Post contrast enhancement showed sensitivity of 92% and specificity of 70% for malignant compression fractures. The hyperintense signal on DWI has 89% PPV for malignancy, while the sensitivity and specificity were 86% and 91% respectively. The mean ADC for malignant fractures was significantly lower than those of osteoporotic fractures (p = 0.0002). Conclusions: SSSEP-DWI is a reliable adjunct parameter that supports conventional MRI in differentiating benign and malignant vertebral fractures.

Nowadays, one of minimally invasive interventions is platelet-rich plasma (PRP) injection that had been explored in some controlled clinical studies to show its effectiveness in treating lateral epicondylitis through inducing inflammation rather than suppressing it. Objectives: The aim of our study was to investigate the effectiveness of ultrasound guided platelet-rich plasma (PRP) injection in treating chronic lateral epicondylitis in addition to identifying the potential sonographic morphological changes in the common extensor tendon (CET) after PRP injection. Results: Statistical analysis showed high significant improvement in all ultrasound findings of common extensor tendon (CET) including echotexture, thickness, cross section, partial tear and calcification in majority of patients. Conclusion: We concluded that US-guided platelet-rich plasma (PRP) injection for treatment of lateral epicondylitis was a safe, minimally invasive and effective procedure in improving the sonographic and pathological changes of common extensor tendon (CET).
