PDFAbstract
Objective To analyze the findings of direct digital X-ray radiography (DR), computerized tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis of chondroblastoma. Methods The imaging data of 39 patients with chondroblastoma who underwent operation in our hospital during January 2014 to December 2015 were analyzed retrospectively. All patients underwent DR, CT and MRI examination, and clinical value of the three methods in the diagnosis of chondroblastoma was compared. Results The detection rates of CT to clear boundary with border sclerosis and calcification in lesions (61.54%, 66.67%) were significantly higher than the detection rates of DR (38.46%, 33.33%) and MRI (35.89%, 41.03%) (P<0.05). The detection rate of MRI to joint effusion surrounding lesions (30.77%) was significantly higher than DR (5.13%) and CT (2.56%) (P<0.05). Conclusion The imaging findings of benign chondroblastomas are distinctive. DR, CT and MRI have their own advantages and disadvantages in the diagnosis of chondroblastomas. The combined diagnosis of the three methods can greatly improve the diagnostic accuracy and reduce misdiagnosis.
