The correct preoperative diagnostic rate by different examinations were as follow: duodenal endoscopy combined with air barium double radiography 95%,duodenal endoscopy 92.3%,air barium double radiography 78.5% and CT 66.6%.
The accuracy of differentiating benign from malign of CT was 78.57% (22/28), and double contrast radiography was 50% (5/10), tumors of extraluminal type were identified incorrectly as outside compression in another 3 cases.
From 1994 to 2004, another RCT was carried out on 28 patients to compare the portal dynamics through three-dimensional dynamic contrast enhanced MR angiography (3D DEC MRA) investigation after operation.
The enrolled included 50 patients with CHD (CHD group) and 30 patients without CHD (control group) who were diagnosed by coronary angiography.
Results from angiography show that the transfer ofVEGF gene into the rat with experimental limb ischemia can stimulate the formation of neovessel, establish collateral circulation, augment blood perfusion, and ameliorate distal limb necrosis.
After regression of the symptoms and electrocardiographic changes, significant pathomorphologic changes of coronary arteries were excluded by coronary angiography.
Coronary angiography and dual-source computed tomography are complementary methods in diagnosis of significant stenosis of the r
This provides a contrast with the existing comparison between the Heisenberg group itself and Euclidean space in terms of Pompeiu sets.
In contrast, under AFM nanoindentation mode, the tip-induced crystallization occurred when a sufficiently high vertical tip force was applied to the melt droplets of PEO with Mn ? 1.0 × 104 g/mol.
PRF-ambiguity resolution for SAR by contrast minimization in range-Doppler domain
The algorithm uses the SAR range migration to resolve the PRF-ambiguity by searching for a PRF-ambiguity number that minimizes the intensity contrast in the range-Doppler domain.
Experimental results show that the approach, compared with traditional methods for resolving the SAR PRF ambiguity, is more suitable for both high contrast scenes such as urban areas and low contrast scenes such as mountains.
They occur 30 to 60 minutes after the end of the arteriography, and almost invariably induce a migrainous paroxysm resembling in most of its characteristics migrainous attacks which occur spontaneously.
Carotid arteriography revealed complete occlusion of the right middle cerebral artery in the first case and occlusion of the prerolandic and rolandic artery on the right in the second case.
