【摘要】 目的 對(duì)比分析、研究50 例橈骨頭骨折患者的計(jì)算機(jī)X 線攝影( CR) 平片、CT 冠狀面
和軸面體位掃描影像。設(shè)計(jì)確定橈骨頭骨折CT 掃描的常規(guī)體位。方法 選用50 例臨床擬診橈骨
頭骨折的患者, 分別攝取橈骨頭部位CR 平片、冠狀面和軸面CT 掃描影像。按臨床采用的Mason 分
型, 對(duì)全部橈骨頭骨折影像進(jìn)行Ⅰ ～Ⅳ分型。結(jié)果 50 例橈骨頭骨折患者的CT 掃描診斷陽性率為
96% ( 48 例) ; CR 平片診斷陽性率為78% ( 39 例) 。經(jīng)CT 冠狀面體位設(shè)計(jì)掃描, 確定分型者占94%
( 47 例) 。經(jīng)CT 軸面體位設(shè)計(jì)掃描, 確定分型者占82% ( 41 例) 。結(jié)論 CT 掃描體位設(shè)計(jì)對(duì)于橈骨
頭骨折分型意義明確。采用冠狀面掃描體位可以滿足常規(guī)臨床影像診斷分型的需要, 對(duì)于Ⅲ 和Ⅳ型
骨折應(yīng)加掃軸面和進(jìn)行三維重組。

【Abstra ct 】 Objective To analyze and compare images of radial head fracture of 50 patients
acquired by computed radiology( CR) , coronal plane and axial plane of CT scan. And to determine routine
plane of CT scan for radial head fracture. Methods Images of of radial head were acquired by CR, coronal
plane and axial plane of CT scan on 50 patients with radial head fracture initially diagnosed by orthopedists.
classify all the cases of radial head fracture into type Ⅰ、Ⅱ、Ⅲ and Ⅳ according to the classification
proposed by Mason. Results The positive incidence of CT and CR were 96% ( 48 ) and 78% ( 39 )
respectively. Cases of 94% ( 47) through CT coronal scan and 82% ( 41) cases through CT axial scan were
exactly classified. Conclusion The designation of the plane of CT scan is significant to the classification of
the radial head fracture. Coronal plane CT scan can meet the need of imaging clinical classification and is
recommended to be routine plane of radial head fracture. In order to ensure the exact classification axial
plane and 3D reconstruction technique should be added for type Ⅲ and type Ⅳ of radial head fracture.
