目的:该研究旨在通过磁共振血管造影详细检查腹腔干(CT),为了确定位置,CT的位置和变化,为外科医生和介入放射科医生提供详细信息,减少导管血管造影的时间.
方法:回顾性分析185例PACS(图片存档通信系统)腹部成像患者的MR血管造影图像。CT的起源水平,根据脊柱,原点角,CT与腹主动脉(AA)分支之间的距离,并评估CT的分支模式。根据性别和年龄评估参数。
结果:CT最常见的来源部位,根据脊柱,在两种性别中都被发现在T12-L1。有一个低,整个研究组患者年龄与CT矢状角(SA)呈正相关(p<0.05)。两种性别最常见的CT分支模式是肝胃脾干,根据Adachi和Uflkacker的分类。男性的CT与肠系膜下动脉(IMA)和CT与主动脉分叉(AB)之间的距离大于女性,差异均有统计学意义(p<0.05)。
结论:了解地点,职位,CT的变异在诊断中至关重要,关于该血管和相关结构的干预类型的鉴别诊断和决策机制。此外,由于图像质量的提高,可以通过MR血管造影获得这些血管的数据,这将防止患者和医生因计算机断层扫描的电离辐射而引起的问题。所提供的数据将构成对每位患者进行详细和个性化解释和评估的基础。因为它们使用MRA提供了有关性别和年龄的CT配置的重要详细信息。
OBJECTIVE: The study aimed to examine the celiac trunk (CT) in detail by magnetic resonance angiography, to determine the locations, positions and variations of the CT, to provide detailed information for surgeons and interventional radiologists, and to reduce the time spent in the catheter angiography.
METHODS: MR angiography images of 185 patients with abdominal imaging in PACS (Picture Archiving Communication Systems) were retrospectively analyzed. The level of origin of CT, according to the vertebral column, angle of origin, distance between CT and branches of the abdominal aorta (AA), and the branching pattern of CT were evaluated. Parameters were evaluated according to gender and age.
RESULTS: The most common origin site for CT, according to the vertebral column, was found to be at T12-L1 in both genders. There was a low, positive correlation between age and CT-Sagittal angle (SA) in the whole study group (p<0.05). The most common CT branching pattern was the hepatogastrosplenic trunk in both genders, according to Adachi and Uflkacker\'s classification. The distance between CT and the inferior mesenteric artery (IMA) and CT and the aortic bifurcation (AB) of males was greater than in females, and the differences were statistically significant (p<0.05).
CONCLUSIONS: Knowledge of the locations, positions, and variations of CT is essential in the diagnosis, differential diagnosis and decision-making mechanisms regarding the type of intervention to be performed for this vessel and related structures. In addition, the fact that data on these vessels can be obtained by MR angiography due to the improved image quality will prevent patients and physicians from the problems caused by the ionizing radiation of computed tomography. The data presented will constitute a basis for detailed and individualized interpretation and evaluation of each patient, as they provide important details about the configuration of the CT concerning gender and age using MRA.
