Abstract

Current methods for the determination of ovarian maturation in fish have shortcomings. They are often time-consuming, inaccurate, and fish are sacrificed during the procedure. A novel noninvasive and accurate method to assess ovarian maturation can be to use magnetic resonance imaging (MRI). Long scanning time is a limitation for use in fish. A clinical MRI with a new sequence employing a shorter scanning time may be more feasible for the assessment of ovarian maturation in female fish. The aim of this study was to investigate ovarian maturation in Channa argus by clinical MRI with the three-dimensional fast spin echo Cube-flex (3D-FSE-Cube-Flex) T₂WI sequence, compared with two traditional sequences. The results demonstrated that compared with two traditional sequences, the 3D-FSE-Cube-Flex T₂WI sequence greatly reduced scanning time (only requiring 140 s per fish) without reducing the scanning quality. A significant correlation (R² = 0.985, p < 0.001, N = 112) was found between the percentage volume of the ovary measured by MRI and the gonadosomatic index (GSI). Besides, ovarian maturation MRI images at different development stages were captured. These findings suggest that clinical MRI with the 3D-FSE-Cube-Flex T₂WI sequence is a rapid, accurate, and noninvasive method for assessing ovarian maturation, with great potential applications in sustainable aquaculture.

磁共振成像用于快速、无创、准确评估活鳢卵巢成熟（Cantor, 1842）

目前测定鱼类卵巢成熟的方法存在不足。它们通常是耗时的，不准确的，并且在过程中会牺牲鱼。磁共振成像（MRI）是一种新的、无创的、准确的评估卵巢成熟的方法。扫描时间长是在鱼类中使用的一个限制。临床MRI采用新的序列，采用较短的扫描时间，可能更可行的评估卵巢成熟雌鱼。本研究的目的是通过三维快速自旋回声立方体-flex (3D-FSE-Cube-Flex) T2WI序列的临床MRI与两种传统序列的比较，研究鳢卵巢成熟情况。结果表明，与两种传统序列相比，3D-FSE-Cube-Flex T2WI序列在不降低扫描质量的前提下，大大缩短了扫描时间（每条鱼只需要140 s）。相关性显著(R2 = 0.985, p <；MRI测量的卵巢体积百分比与促性腺指数（GSI）之间的差异为0.001,N = 112)。同时采集不同发育阶段的卵巢成熟MRI图像。这些结果表明，临床MRI 3D-FSE-Cube-Flex T2WI序列是一种快速、准确、无创的评估卵巢成熟的方法，在可持续水产养殖中具有很大的应用潜力。

期刊介绍： Aquaculture is an international journal for the exploration, improvement and management of all freshwater and marine food resources. It publishes novel and innovative research of world-wide interest on farming of aquatic organisms, which includes finfish, mollusks, crustaceans and aquatic plants for human consumption. Research on ornamentals is not a focus of the Journal. Aquaculture only publishes papers with a clear relevance to improving aquaculture practices or a potential application.
