An operator-blinded dual modality trial of measurement of lumbar multifidus muscle cross-sectional area was performed.
To compare two imaging modalities used for measurement of the lumbar multifidus muscle.
Ten normal female subjects aged 21-31 years were imaged on two separate days using magnetic resonance imaging and ultrasound imaging. Bilateral measurements were made at each vertebral level from L2-S1.
No significant difference was demonstrated between cross-sectional area measurements made with the two different modalities. Measurements of multifidus were symmetrical between left and right sides of the spine. For both modalities, a significant difference was demonstrated in the cross-sectional area of multifidus between each vertebral level from L2-S1.
The present study indicated that if a strict protocol for ultrasound imaging is adhered to, real-time ultrasound imaging can be used to document muscle size in young adults. Further studies are required to validate the technique in older subjects and in different conditions.
进行了一项由操作者盲法的腰椎多裂肌横截面积测量的双模态试验。
比较用于测量腰椎多裂肌的两种成像方式。
10名年龄在21 - 31岁的正常女性受试者在两天内分别接受磁共振成像和超声成像。从L2 - S1的每个椎体水平进行双侧测量。
两种不同方式测量的横截面积之间未显示出显著差异。多裂肌的测量在脊柱左右两侧是对称的。对于两种方式，L2 - S1每个椎体水平之间的多裂肌横截面积都显示出显著差异。
本研究表明，如果严格遵守超声成像方案，实时超声成像可用于记录年轻人的肌肉大小。需要进一步研究以验证该技术在老年受试者和不同条件下的有效性。
