\ Results\ Multiple pulmonary nodules of soft dense appeared in 6 cases on CT scans, the map like pulmonary infiltritive dense in 2 cases,the peripheral wedge shaped shadows on the pleura in 3 cases.
Lesions of the white matter were found in 8 of the 17 patients. The white matter lesions displayed three distinct patters, such as thin radial bands, wedge shaped lesion, and nonspecific foci. These lesions were iso to hypointense to white matter on T 1WI and hyperintense to gray and white matter on T 2WI.
Materials and Methods:Using a cuniform pad on the pressing ball,correct and reduce the movement of the pressing ball caused by the obese patient′s abdomen expansion as well as the influence caused by the alteration of the pressing acting force.
Results:Divide the cases into two groups. 32 cases usre cuniform pad and 24 cases,as a control group,do not use. It is shown that the cuniform pad group has superior ureter pressing effect to the control group.
Conclusion:To some extent,exerting a cuniform pad on the pressing ball can ameliorate the effect of ureter pressing in the obese patient vein urography.
Although CEMRA demonstrated less obstructed pulmonary arteries than DSA (5/10 vs 8/10)did, it detected all obstructions when combined with PPI. The pulmonary infarction zones showed wedge-shaped perfusion defects on the PPI images, with the signal intensities lower than those of the normal areas (137.86±45.32 vs 330.14±46.52, P<0.001).
Whereas among the 34 lesions of wedgeform,there were 25 cases of inflammatory pseudotumor and only 5 peripheral cancer as wedgelike,3 tuberculosis and 1 abscess.
The parabolic equation method permits one to develop valuable and flexible techniques to solve high frequency scattering problems in wedge shaped regions.
Such configurations belong to wedge shaped regions in the parameter space and their existence in the tetragonal and hexagonal classical Heisenberg model was proved in the smallQ limit.
These include wavenumber shifts of the absorption bands, the influence of a wedge shaped cell and limited spectral resolution.
Due to the wedge shaped arrangement of the saw cuts the segment fits exactly in its bed, needing no further fixation.
We have described techniques for the reconstruction of the lower lip, especially the wedge shaped excision, the methods developed by Dieffenbach, Langenbeck, Estlander, Gillies, Weerda, Bernard and Grimm.
The clinical and X-ray findings in 20 cases with pulmonary embolism are reported. The chief symptoms of this disease are chest pain, eaugh, hemoptysis and dyspnea. Roentgenographic findings include the shadow appears in pulmonary field(18/20), pleural effusion (6/20), decrease of lung markings(3/20)and elevation of the diaphragm, etc. A triangular-appearing infiltration with it base contiguous to a visceral pleural surfacc(so-called Hampton's hump)are clearly visible(2/20). Usually a correct diagnosis could...

Usually a correct diagnosis could be made bycombination of clinical and roentgenotogical findings.
The analysis were performed on the colour flow Doppler echocardiographic features of congenital double chambered right ventricle (DCRV). In 7 cases, the parasternal short axis view at the level of aortic root revealed the anomalous tongue-shaped right ventricular muscle mass proturding from the aortic side into the cavity of right ventricle (RV) which was over against the wedge-shaped muscle mass protruding from the anterior wall of the RV. In 6 cases, the apical four chamber view revealed two local tongue-shaped...
The analysis were performed on the colour flow Doppler echocardiographic features of congenital double chambered right ventricle (DCRV). In 7 cases, the parasternal short axis view at the level of aortic root revealed the anomalous tongue-shaped right ventricular muscle mass proturding from the aortic side into the cavity of right ventricle (RV) which was over against the wedge-shaped muscle mass protruding from the anterior wall of the RV. In 6 cases, the apical four chamber view revealed two local tongue-shaped muscle masses protruding from the free wall of the RV and the middle portion of IVS respectively. The protruding muscle masses of the RV and the IVS divided the cavity of the RV into two chambers, a proximal chamber just below the tricuspid valve and a chamber distal to the anomalous muscle. A stenosed orifice was formed between the proximal chamber and the distal chamber. The IVS proximal to the protruding muscle masses curved convex toward the LV at the end-systole and become flat at diastole. In 12 cases, there are above-mentioned echocardiographic features of anomalous hypertrophic muscles. DCRV may coexist with a VSD in 20 cases, PS in 4, ASD and tricuspid stenosis in 1. Colour flow Doppler imaging is very useful for diagnosing DCRV. In 20 cases, the apical four chamber view revealed that two steams of flow are close but in the reverse direction in systole. A mosaic fountain-shaped flow jet passed through the stenosed orifice of the anomalous muscles and a bluish mosaic regurgitation passed through the tricuspid orifice. In the article, we disucssed the pathoana-tomy, echocardiographic features, type and the differential diagnosis of DCRV.
The doses at three points along the oblique direction of isodose line at the same depth aremeasured.The wedgeangle and the line-oblique angle are derived from these doses measured according to the following formula:The wedge angles calculated by above formula were compared with these measured by 3-D water-scanner phantom,It was found that the results were very closed,this confirmed the correctness of the for-mula.It is recommended that the wedge angles may be measured before its use,because the wedge anglesvaries...
