Abstract: Extrapulmonary tuberculosis includes multiple systems, organs, sites and various types of tuberculosis and its diagnosis is relatively difficult than pulmonary tuberculosis. Timely and accurate diagnosis is the prerequisite for patients to be treated regularly and effectively. Imaging examination plays an important role in the lesions finding, diagnosis, differential diagnosis and the dynamic observation of lesions. Conventional imaging examination including ultrasonic, X-ray, CT, MRI and bone scanning has positive value of extrapulmonary tuberculosis diagnosis and curative effect observation. However, it has also some limitations. With the rapid development of ima-ging technology, in addition to study of morphological lesions, the molecular and functional imaging technology has become the development tendency and the research hotspot in the world. It is very important for diagnosis and differential diagnosis of extrapulmonary tuberculosis, especially central nervous system tuberculosis.
