PurposeTo评估是否体积测量的节段性血管损伤（SVI）的基础上，在初始创伤调查中获得的计算机断层扫描（CT）成像与未来的核医学（NM）分裂renal function.MethodsA回顾性分析肾外伤患者在一级创伤中心治疗2008年和2015年之间。对初次CT成像和随访NM肾扫描显示单侧SVI的患者进行了评价。CT为基础的分裂肾功能计算通过评估同侧未受伤的肾脏体积的比率，双边总未受伤的肾脏体积由两个独立的radiologist.Results8例单侧SVIs的初步CT创伤评估进行了后续NM肾扫描平均4个月（范围2-6）损伤后。损伤肾脏的平均NM分裂肾功能为43%（范围22-57）。基于受累肾脏的CT体积测量，平均损伤百分比为23%（范围7-62），计算的平均分裂肾功能为44%（范围23-60）。计算的平均CT分裂函数与NM分裂函数相关（R= 0.89）。CT容积测量的组内相关性测量评分者间可靠性为0.94（95%置信区间0.72-0.99）。ConclusionVolumetric测量的基础上获得的CT成像在初始创伤评估与未来NM分裂肾功能后SVI评分者间可靠性高。该方法利用预先存在的成像并且避免来自NM扫描的额外辐射暴露、工作负担和财务成本。需要进一步评估，以评估更复杂损伤的可行性。
PurposeTo evaluate whether volumetric measurements of segmental vascular injuries (SVIs) based on computed tomography (CT) imaging obtained during an initial trauma survey correlate with future nuclear medicine (NM) split renal function.MethodsA retrospective review was performed of renal trauma patients treated at a level 1 trauma center between 2008 and 2015. Patients with unilateral SVIs on initial CT imaging with follow-up NM renal scans were evaluated. CT-based split renal function was calculated by assessing the ratio of ipsilateral uninjured kidney volume to bilateral total uninjured kidney volume by two separate radiologists.ResultsEight patients with unilateral SVIs on initial CT trauma evaluation underwent follow-up NM renal scans at a mean of 4 months (range 2–6) after injury. Mean NM split renal function of the injured kidney was 43% (range 22–57). Based on the CT volumetric measurements of the affected kidney, mean percent injured was 23% (range 7–62) with a calculated mean split renal function of 44% (range 23–60). Calculated mean CT split function correlated with NM split function (R= 0.89). Intraclass correlation measuring inter-rater reliability for CT volumetric measurements was 0.94 (95% confidence interval 0.72–0.99).ConclusionVolumetric measurements based on CT imaging obtained during the initial trauma evaluation correlated with future NM split renal function after SVIs with high inter-rater reliability. This method utilizes pre-existing imaging and avoids additional radiation exposure, work burden, and financial cost from a NM scan. Further evaluation is required to assess feasibility with more complex injuries.
