Abstract:
Aim of work:
To evaluate the diagnostic accuracy of ultrasonography technique in cases of acute ankle injury compared to magnetic resonance technique.
Background:
The ultrasound technique is a rising up modality, widely available, cheaper and faster technique than MRI. in evaluation of the musculoskeletal diseases.
Patients and Methods:
Our study was carried out in Radiology department, Zagazig University Hospital, and had been approved by the Zagazig University Institutional Review Board (I.R.B.).
We targeted 24 patients. Where 66.7 % were males and 33.3 % were females representing of all patients, with mean age 29.75 year.
Thirteen patients complained of right side ankle trauma representing 54.2%, while the other eleven patients complained of left side acute ankle trauma representing 45.8% of all patients
Results
In our study, 24 studied patients with 39 lesions, with the majority were tendonous lesions, 21 tendon injuries representing 53.8% of all lesions.
The other 5 patients showed 7 ligamentous injuries representing 17.9% of all lesions.
Among the studied patients, 11 patients showed non tendonous non ligamentous injuries.

CONCLUSION:
Ultrasonography with the advent of high resolution linear-array as a dynamic, rapid and inexpensive imaging tool and with a high accuracy as magnetic resonance imaging, can be used as a first line diagnostic modality in patient with acute soft tissue injuries
Magnetic resonance imaging is an excellent technique for those cases where the diagnosis is uncertain or cannot be confirmed by ultrasonography, especially when surgical interference is planned.
