發(fā)布時(shí)間:2020-07-25 11:10
【摘要】: 目的:通過(guò)對(duì)比各種影像學(xué)診斷方法在兒童急性血源性骨髓炎早期診斷時(shí)間上的差異,提出同位素骨掃描的優(yōu)點(diǎn)。 方法:在近6年住院的兒童急性骨髓炎61例(64部位)確診病例中,對(duì)其中12例常規(guī)B超及X線尚未發(fā)現(xiàn)明顯陽(yáng)性改變者,行同位素骨掃描檢查,陽(yáng)性結(jié)果出現(xiàn)后,7例行骨鉆孔引流或開窗減壓,術(shù)后抗感染治療2周以上。部分病例隨訪1年以上。綜合病例資料,分別按各檢查出現(xiàn)陽(yáng)性結(jié)果的時(shí)間以例數(shù)和時(shí)間列表,對(duì)數(shù)據(jù)進(jìn)行計(jì)數(shù)和計(jì)量統(tǒng)計(jì)分析比較。 結(jié)果:采用骨掃描診斷病例陽(yáng)性結(jié)果出現(xiàn)時(shí)間較X線平片和B超早,早期診斷處理的患兒出現(xiàn)嚴(yán)重并發(fā)癥及后遺畸形的可能性大大降低。 結(jié)論:應(yīng)用骨掃描早期診斷兒童骨髓炎靈敏度較X線平片和B超高。早期診斷處理的患兒預(yù)后較好。

There is a significantincrease of radioactivity in the metaphysisof right lower femur and upper tibia圖 3:三相骨掃描延遲相(骨靜態(tài)顯像):前位及后位圖,可見左股骨下端骨骺及干骺端、右脛骨上端骨骺放射性明顯較對(duì)側(cè)增強(qiáng),左股骨中下段放射性較對(duì)側(cè)減弱,提示該處亦受累,尚處早期Fig3:Bone static imaging: anterior and posteriorfiguration. There is a significant increase ofradioactivity in the metaphysic of left lower femurand upper tibia, however a decrease of radioactivityin the middle and lower left femur, which suggestthis part is also involved and it happened recently

圖 2:三相骨掃描血流相、血池相及延遲相局部放射性活度定性及定量以及左右側(cè)時(shí)間放射曲線對(duì)比。血池相左右放射性活度比值為 0.27;延遲相左右放射性活度比值為 0.26?梢妭(gè)時(shí)相患側(cè)股骨遠(yuǎn)端放射性活度均較健側(cè)明顯增高。Fig2: Three phases bone scanning, perfusion phase, blood pool phase and delayed phase. Anthe time activity curve of both left and right legs. Blood pool radioactive ratio is 0.27; skeletaradioactive ratio is 0.26. In all three phases there is a significant increase of radioactivity in tright lower femur
