ABSTRACT
Objective By givng patients psychological nursing,attributing them to cooperation in the examination,perfect images and the correct diagnosis can be obtained. Methods Explaining the knowledge of the equipments and the examination, broadcasting videos ,improving the environment of the waiting-room,and telling the family the details of examination, can reduce or eliminate mental burden of the patients. Results 98% of the patients' mental burden are relieved. Conclusion Knowing patients' informations carefully is the key of the mental nursing. Every patient has different experience,background, the width of knowledge and the details of the examination. Different plans on psychological nursing based on that lead to satisfying results.
ABSTRACT
Objective To discuss the effect of bowel preparation on 18F-FDG PET/CT imaging. Methods 250 results of 18F-FDG PET/CT imaging were reviewed and analyzed with SUV, medical history and other clinical data. Results In 42 patients without sufficient bowel preparation,17 results of imaging were interfered by the alimentary canal. In contrast, in 208 patients with sufficient bowel preparation, only 4 results of imaging were interfered by the alimentary canal. Conclusion Correct and sufficient bowel preparation is a important factor to elevate 18F-FDG PET/CT imaging quality.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the diagnostic value of MRI and SPECT in early postburn brain edema in severely burned dogs.</p><p><b>METHODS</b>Twenty-six mongrel dogs were randomized into control (n = 6) and burned groups in which every 5 dogs were allotted to each of following time points: 6, 12, 18 and 24 postburn hours (PBHs). The dogs in burn groups were inflicted with 50% TBSA of III degree skin burn and were infused with 5% glucose solution after 6 PBHs, so that severe early postburn brain edema was produced. MRI and SPECT were employed to observe dynamically the brain of dogs in all groups. The results were collected and compared with one another.</p><p><b>RESULTS</b>The results indicated that with MRI brain morphological change of early brain edema could be shown as early as within 12 PBH and diffuse brain edema became more obvious with elapse of time. The changes might be difficult to be found by MRI when T(1)WISIR decreased below 10%. T(2)WI SIR increased by 8.29% at 24 PBH with blurred demarcation between the brain gray and white matters. There was diffused and progressive nuclide ((99)TCm-ECD) concentration in the brain tissue as shown by SPECT at 6 PBH. The radio-nuclide taking ratio increased significantly after 12 PBH, especially at 24 PBH (P < 0.01) when compared with that before burn.</p><p><b>CONCLUSION</b>Combined application of MRI and SPECT could evidently increase sensitivity and specificity in the diagnosis of early postburn brain edema.</p>
