Objective To evaluate the sonographic characteristics of peripheral focal inflammation of lung, and to improve the diagnosis and differential diagnosis potency of sonography for pulmonary peripheral lesions. Methods The sonogram of 44 patients with peripheral focal inflammation of lung were retrospectively analyzed and compared with the sonogram of other lesions. Independent variables included lesion’s margin, echotype, the secondary change of visceral pleura, the angulation of lesion’s inner surface and air bronchogram. Lesion’s nature was as dependent variable. The data was analyzed by Logistic regression analysis. Pathological results were confirmed by biopsy. Results The angulation of lesion’s inner surface and air bronchogramwere significant factors affecting the diagnosis of peripheral focal inflammation of lung( P lt;0. 01) . Compared to the pathological yield by biopsy, angulation of lesion’s inner surface being acute angle for diagnosis of peripheral focal inflammation of lung had an accuracy rate of 82. 6% , a sensitivity of 72. 7% , a specificity of 84. 7% , a positive predictive value of 51. 0% , and a negative predictive value of 93. 4%. Conclusions The acute angle of lesion’s inner surface and air bronchogram are sonographic characteristics of peripheral focal inflammation of lung. Bedside lung ultrasound is useful to the diagnosis of peripheral focal inflammation of lung.
Objective To approach the clinical values of computer tomography (CT) examination technique and imaging features in abdominal cavity parenchymal organs injury. Methods One hundred and fifty-nine patients with abdominal cavity parenchymal organs injury were examined by CT of plain scan and (or) contrast enhancement, the enhancement included arterial phase, parenchymal phase and the kidney scanning delay phase, the results of CT scanning were compared. Results Ninty-eight cases among 159 patients were diagnosed as the abdominal cavity parenchymal organs injury by the CT, the diagnosis accordance rate was 98.1% (156/159) by operation and follow-up, 22 cases were simple viscus damage or back bone and pelvic fracture, 39 cases were negative, the examination positive rate was 75.5% (120/159). Conclusion The CT can display the parenchymal organ traumatic condition, subcapsule hematoma, retroperitoneal hematoma, seroperitoneum and injured grade. It is the first selective examination to use CT scanning in abdominal cavity parenchymal organ damage, and it has important clinic values to use correct scanning techniques in abdominal injury examination.
