Panoramic ultrasound is one of the recently introduced ultrasound evaluation techniques. We herein examined the relationship between the cross-sectional area of the rectus femoris muscle on panoramic ultrasound and its volume based on the gold standard computed tomography (CT) evaluation.
This was a single-center prospective observational study. A panoramic ultrasound assessment of the cross-sectional area of the rectus femoris muscle and a simple CT evaluation of its volume were performed on days 1 and 7 of hospitalization. Physical functions were assessed at discharge.
Twenty patients were examined. The rate of change in the cross-sectional area of the rectus femoris muscle on panoramic ultrasound correlated with that in its volume on CT (correlation coefficient 0.59, p = 0.0061). In addition, a correlation was observed between the absolute value for the rectus femoris muscle cross-sectional area on panoramic ultrasound and physical functions at discharge. Rectus femoris muscle distances did not correlate with either.
In the acute phase of critical illness, the cross-sectional area of the rectus femoris muscle on panoramic images correlated with its volume on CT and, thus, it is a valid method for assessing muscle mass.
全景超声是最近引入的超声评估技术之一。本研究旨在根据金标准 CT 评估，检查全景超声测量的股直肌横截面积与其体积之间的关系。
这是一项单中心前瞻性观察性研究。在住院第 1 天和第 7 天进行股直肌横截面积的全景超声评估和简单的 CT 体积评估，并在出院时评估身体功能。
共检查了 20 例患者。全景超声测量的股直肌横截面积的变化率与 CT 测量的股直肌体积的变化率相关（相关系数 0.59，p=0.0061）。此外，还观察到全景超声测量的股直肌横截面积的绝对值与出院时的身体功能相关。股直肌距离与两者均无相关性。
在危重病的急性期，全景图像上的股直肌横截面积与 CT 上的股直肌体积相关，因此，这是一种评估肌肉质量的有效方法。
