PDFAbstract
Objective To make a thorough inquiry about the MRI imaging features of the tuberculosis of lumbar spine 3-5 with cold abscess and to explore the diagnostic value of MRI in this area. Methods To analyse the MRI images of 50 patients with tuberculosis of Lumbar spine between L3 and L5 with cold abscess identified by surgery from June 2012 to May 2016 in our hospital. And enhancement degree, type of the tumour and the infection degree of surrounding tissue were classified and analyzed. Results The results of analysis told that: the total diagnostic rate was 88%. The diagnosis rate of patients with concurrent cold abscess was 91.3%. The features of MRI image show: T1WI signal of the lesion area was decreased; the T2WI signal was enhanced, and when the STAIR sequence was flat, the signal was high. In enhanced scan, the lesion area of bone was destructed and the surrounding muscles are not evenly enhanced. Conclusion There is a typical image features in MRI image of tuberculosis of Lumbar spine between L3 and L5 with cold abscess and MRI can make an accurate diagnosis.
