ABSTRACT
Objective To analyze the image findings of renal tuberculosis and evaluate the merits and disad vantages of various imaging diagnostic methods, then choose the most sensitive one. Methods The KUB, IVP, AP and CT findings of 48 patients with renal tuberculosis which had been convinced by operations were evaluated and compared. Results The diagnosis rates of KUB and IVP were 41.7% (20/48), AP of 62.5 % (10/16), CT of 100 % (48/48). The characteristic findings of CT were multiple low density lesions, with "flower petals" shape gath-ered in sections. Conclusion CT has a great value for diagnosing renal tuberculosis.
ABSTRACT
Objective To analyze CT features of the pulmonary segment lesions.Methods The CT findings of 88 patients with pulmonary segment lesions were reviewed.The diseases included chronic pneumonitis(n=30),tuberculosis(n=24),lung cancer(n=34),all proved pathologically.Results Wedge-shape or cone-shape of lesions was demonstrated in most of cases.In chronic pneumonitis,the border of lesion was depression or straight without hilar mass and bronchus obstructed.Most lesion was isodensity and the air bronehogram could be found in some cases.In tuberculosis,the border was irregular or hazy with different density inside the lesion(cavity,calcification,bronchieetasis).Satellite-lesion and thickening of the pleura nearby were found commonly.In lung cancer,the hilar mass and pot obstructed bronchus were the characteristic,with the border evagination in some cases.According to the above,82% of the cases were diagnosed correctly.Conclusions Some relative specific CT manifestation existed in the pulmonary segment lesions caused by chronic pneumonitis,tuberculosis and lung cancer.But the CT of some patients were similar to each other,of which diagnosis must be based on pathology.
