The Difference

Aim: To explore the diagnostic value of spiral CT chest enhanced scan for adults with active pulmonary tuberculosis. Methods: The clinical data of 60 adult patients with active pulmonary tuberculosis who were treated in our hospital from January 2018 to November 2019 were retrospectively analyzed. All patients underwent conventional chest radiography and spiral CT chest enhanced scan. The number of tuberculosis diagnosis, the detection rate of special site lesions, and the detection rate of active pulmonary tuberculosis signs by the two methods were compared. Results: In 60 patients, the pathological results confirmed the existence of 75 tuberculosis lesions. The detection rate of spiral CT was 98.67%, which was not statistically significant compared with the detection rate of 92.00% (P>0.05) in the conventional chest X-ray. The detection rate of spiral CT enhanced scans for tuberculosis lesions in special sites was 100.00%, which was significantly higher than that of conventional chest X-ray of 7.69%, and the accuracy rate of active pulmonary tuberculosis signs was 98.85% higher than that of conventional chest X-ray of 79.31%. P<0.05). The difference was statistically significant (P<0.05). Conclusion: Spiral CT chest enhanced scan can not only find special tuberculosis lesions that cannot be detected by conventional chest radiography, but also accurately determine active pulmonary tuberculosis in adults, which is of high diagnostic value.

AbstractTuberculosis remains a major global health issue affecting all countries and age groups. Radiology plays a crucial role in the diagnosis and management of pulmonary tuberculosis (PTB). This review aims to improve understanding and diagnostic value of imaging in PTB. We present the old, well-established findings ranging from primary TB to the common appearances of post-primary TB, including dissemination with tree-in-bud nodularity, haematogenous dissemination with miliary nodules and lymphatic dissemination. We discuss new concepts in active PTB with special focus on imaging findings in immunocompromised individuals. We illustrate PTB appearances borrowed from other diseases in which the signs were initially described: the reversed halo sign, the galaxy sign and the cluster sign. There are several radiological signs that have been shown to correlate with positive or negative sputum smears, and radiologists should be aware of these signs as they play an important role in guiding the need for isolation and empirical anti-tuberculous therapy.

Abstract The relative rates of incorporation of Fe59 into heterogenic hemoglobins was studied in four patients with sickle cell trait. Three of the patients were free of superimposed disease, while one had active pulmonary tuberculosis. In all subjects there was a significantly greater incorporation of radioiron, per milligram of hemoglobin, into hemoglobin S than into hemoglobin A. The data indicate that in sickle cell trait the rates of synthesis of the heterogenic hemoglobins are not proportional to their circulating concentrations. Two interpretations appear possible. Since the size of the intra-marrow pool of hemoglobin S was not known, it is possible that there exists a smaller preformed pool of the abnormal hemoglobin, with the isotope making its appearance first in hemoglobin S. However, it is also possible that hemoglobin S is synthesized at a rate which is greater than that reflected by its circulating concentration. This implies that the relative concentrations of hemoglobin S and hemoglobin A vary from erythrocyte to erythrocyte, and that those cells with the greatest proportion of hemoglobin S are selectively destroyed.
