高品质的食用鱼，如黄尾鱼，通常以完整的状态通过分销渠道。因此，鱼肉的质量和成分只有在加工后才能确定。我们研究了磁共振成像（MRI）是否可以用于完整的黄尾鱼的质量和成分评估。选择的因素在腹，侧线，背部和血液颜色区域的胸鳍切片和肛门切片从自然和养殖的黄尾鱼（Seriola quinqueradiata）的个体进行了测量比较。具体而言，在3T MRI扫描仪上使用具有T2* 校正的受扰多回波梯度回波测量脂肪分数和T2*。使用单次激发扩散回波平面成像测量表观扩散系数（ADC）和各向异性分数（FA）。使用T2加权多回波快速自旋回波测量T2和筋膜密度。在大多数地区的脂肪分数值显着高于养殖黄尾鱼与自然鱼。在胸鳍切片的腹侧区域观察到最高的脂肪分数。养殖黄尾鱼的FA和T2值大于天然鱼，ADC和T2* 值小于天然鱼。筋膜密度没有显着差异之间的天然和培养的黄尾鱼，除了在腹鳍片的腹侧区域。MRI可以评估完整黄尾鱼的区域质量和组成。
High‐quality food fish, such as yellowtail often pass through a distribution channels in an intact state. Thus, the quality and composition of the fish meat can only ascertained after processing. We investigated whether magnetic resonance imaging (MRI) could be feasibly used for quality and composition assessments of intact yellowtail. Selected factors at the ventral, lateral‐line, dorsal and blood‐colour regions of a pectoral‐fin slice and an anal slice from natural and cultured yellowtail (Seriola quinqueradiata) individuals were measured for comparison. Specifically, the fat fraction and T2*were measured using spoiled multi‐echo gradient echo with T2*correction on a 3T MRI scanner. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were measured using single‐shot diffusion echo‐planar imaging. T2and fascial density were measured using T2‐weighted multi‐echo turbo spin‐echo. Fat fraction values at most regions were significantly higher in cultured yellowtail compared with natural fish. The highest fat fraction was observed at the ventral region of the pectoral‐fin slice. FA and T2values were larger, while those for ADC and T2*were smaller in cultured yellowtail than in natural fish. Fascial densities did not differ significantly between the natural and cultured yellowtail except in the ventral region of the pectoral‐fin slice. MRI makes it possible to assess regional quality and composition of intact yellowtail.
