5. ObjectiveTo explore the mammography findings and cause of radiolucent ring and its diagnostic value in the benign and malignant lesions.
   目的探讨乳腺肿块低密度环的表现、成因及对良恶性病变的诊断价值。
6. No complications were found in other patients. The average following up was 3 years and average Harris score was 87.The X-ray showed that none of the patients was presented the radiolucent lines in the acetabular mattress, bone transplantation, reconstructive titanium plate and interface of polyethylene liner.

7. On SCTU, the location and diameter of 9 ureteral calculus ( 8 radiolucent, 1 radiopaque) and enlargement of renal pelvis and ureter were displayed.
   SCTU图像上，8例阴性和1例阳性结石可见其位置、形态、大小及扩张的肾盂和输尿管；
8. Radiographically, the radiolucent lines happened more in the distal humeral component than in the proximal humeral component, with the incidence of radiolucent lines around the humeral component for 14% ( 6/ 44) and the radiolucent index less than one, indicating no loosing.

9. This disease is renal mesenchymal tumor and because of more fat tissues, it can show a characteristic irregular patchy radiolucent area in the renal mass in the x-ray plain film.
   本病系肾实质间叶组织肿瘤，因含较多脂肪组织，故X线平片肾肿块区有不规则斑片状密度减低透亮区。
10. Recurrent patients were treated successfully. Conclusions: The ureteral radiolucent calculi can be diagnosed more correctly preoperation by combining B ultrasound 、 IVU and spiral CT scan;
    结论：术前结合B超、IVU所示，再酌情加行CT扫描，可以提高输尿管阴性结石的确诊率；
