CAV法比ABC/2法测量颅脑损伤出血量及预测预后更准确 - 知乎
网页外伤性脑损伤（TBI）急诊评估的重要指标是颅内出血量。 最广泛使用的快速体积估计法是ABC/2，这是一种将病灶近似为完美的椭球体的简单算法。 基于更精确血肿体积测量的相对预后仍然未知。 美国布朗大学神经外科的Owen P. Leary等比较ABC/2法和计算机辅助容积测定法（computer-assisted volumetry，CAV）对轴内和轴外创伤性出血的测量结果。 量化两种方法测量结果与中重度TBI患者预后的关系。 结果发表于2021年3月的《Journal of …
The ABCs of Measuring Intracerebral Hemorrhage Volumes
网页1996年8月1日 · The ABC /2 method required a mean time of 38 seconds (range, 70 to 210 seconds). In the subset of 20 CT scans measured by four different readers, we noted excellent interrater (intraclass correlation=.99) and intrarater (intraclass correlation=.99) reliability when the ABC /2 technique was used (Table 2).

ABC/2 estimation in intracerebral hemorrhage: A comparison …
网页2019年10月1日 · ABC /2 (in mL): 95% confidence intervals (CIs) for mean difference & limits of agreement for 6 raters vs. index radiologist, comparing limits of agreement by bleed volume (top-quartile versus lower-three quartiles). The bleeds were categorized as ellipsoidal in 37 out of 100 CT scans by the index radiologist.
Comparison of the ABC/2 Estimation Technique to Computer …
网页1998年9月1日 · The volumes of 298 intraparenchymal hematomas were measured by the ABC/2 technique, and the volumes of 44 subdural hematomas were measured by an adaptation of this technique and compared to computer-assisted volumetric analysis.
Clarification of abc /2 Rule for ICH Volume - AHA/ASA Journals
网页2007年1月25日 · Calculating Volume=abc /2 is based on the assumption that the ICH volume can be approximated by an ellipsoid. This is a good assumption as long as the hemorrhage is not multilobulated or otherwise very irregular in shape.

Management of acute moderate and severe traumatic brain injury
网页2024年8月13日 · The severity of TBI is most commonly graded using the Glasgow Coma Scale (GCS), assessed following the initial resuscitation and within 48 hours of injury (table 1) [4]. Severe TBI is defined by a GCS score <9 [5]. Moderate TBI includes patients with a GCS score of 9 through 13.
