Value of ultrasound guided biopsy combined with Xpert Mycobacterium tuberculosis/resistance to rifampin assay in the diagnosis of chest wall tuberculosis

Figure 1 Ultrasound-guided biopsy. A: Gray scale ultrasound-guided (USG) images clearly reveals the lumps in the chest wall; B: Gray scale USG images clearly reveals the hypoechoic nodules in the chest wall; C: Color Doppler clearly shows the blood flow in a chest wall tuberculosis; D: The ultrasound directs the puncture needle when performing the biopsy.
