ABSTRACT
Objective: To analyze the clinical value of 16-slice CT angiography techniques in cerebral artery lesions. Methods:Forty three cases in our hospital with suspected cerebrovascular disease who performed computed tomography angiography were retrospectively analyzed. Volumetric imaging, maximum intensity projection and multi-planar reconstruction technique for three-dimensional reconstruction process were used in post-processing. Results:There were 27 cases with no abnormal blood vessels, 6 cases with aneurysm, 1 with arteriovenous malformation, 8 with arterial stenosis and 1 with congenital abnormalities. The image quality analysis of cerebral vascular trunk and main branches was 100%performed in 43 cases. The location, shape, size, and the relationship with the surrounding blood vessels and skull of the aneurysm have been clearly shown, and the nidus, feeding arteries and draining veins have also been clearly shown. Conclusion:With the features of safe, fast, non-invasive and clarity in images, 16-slice CT angiography imaging technology can be used as the first choice of screening cerebral arterial disease.
ABSTRACT
Objective:To explore the CT manifestations and pathological features of pneumonia-type lung cancer, and to improve the diagnosis capability of pneumonia-type lung cancer. Methods:CT and pathologic features of 23 cases ofsurgical pathology or biopsy confirmed pneumonia-type lung cancer patients were retrospectively analyzed and classified according to the new pulmonary adenocarcinoma classification. Results:Among the 23 pneumonia-type lung cancer subjects, CT showed 12 cases with lung pulmonary consolidation shadows, for sheets or diffuse distribution of density increase, combined with cysts or honeycomb lung symptom in 7 cases. 5 cases as inflatable bronchial symptoms within the consolidation, 3 cases bronchial stiffness, narrowed lumen to uneven thickness of 2 case, combine with circuity twigs with change.7 cases of nodular for grinding glass, including 4 cases of mixed ground glass nodules, around with focal nodular. 3 case of the lumps, fibrosis and consolidation of mixed picture. 3 case of pure grinding glass nodules and fibrosis. Results:Pathology results revealed 13 cases of adenocarcinoma, bronchioloalveolar carcinoma in 5 cases, 4 cases were squamous carcinoma, papillary adenocarcinoma in 1 case. Conclusion: CT features of pneumonia-type lung cancer are single or multiple opacities, within which inflatable bronchial symptoms can be observed, with multiple nodules andground glass shadowing, cysts or honeycomb symptom can also be found concomitant, thelesions expand, increase and spread to both lungs, taking its dynamic change features intoconsideration will also help to improve the diagnostic accuracy.
