CT manifestations of pulmonary tuberculosis

CT manifestations of pulmonary tuberculosis are very simple. Typical CT manifestations of pulmonary tuberculosis are very simple: typical parts, typical shapes. Not simple, difficult, atypical pulmonary tuberculosis, early or special parts, these are often difficult to diagnose. Typical good parts are the tips of the upper lobes of both sides and the dorsal segment of the lower lobes. Some doctors may not be particularly clear about the segmentation of the lungs. Simply speaking, the posterior segment is the apex of the lungs, which can be understood as the apex of the lobes. From the chest X-ray, the dorsal segment of the lower lobe is in the middle, which is the best place for tuberculosis to occur. Why tuberculosis tends to grow in these places, because these places are relatively high, less congested and more inflated. This blood gas coordination ratio is most suitable for tuberculosis growth, which is the reason why it is easy to occur. Another is that its morphology is often in various forms, patchy, nodular and strip-like, which are very common.
