Knowledge of the morphologic features and ligamentous attachments of the ovaries, the relationship of the ovary to the ureter, and the course of the ovarian vein and artery is necessary for confident recognition of the ovaries and differentiation between ovarian and nonovarian masses with computed tomography (CT). The suspensory ligament attaches the ovary to the pelvic sidewall and transmits the ovarian vein and artery. This ligament may be seen at CT as a linear or fan-shaped soft-tissue band leading to the ovary. The utero-ovarian ligament is occasionally visualized with CT as a soft-tissue band between the uterus and ovary. The ovaries are usually located anterior or anteromedial to the pelvic ureters, whereas iliac lymph nodes are lateral or posterolateral to the ureters. Therefore, an ovarian mass displaces the ureter posteriorly or posterolaterally, whereas a large lymph node mass displaces the ureter medially or anteromedially. An ovarian mass may be draped by ovarian parenchyma, thus revealing the origin of the mass. Tracking the ovarian vein from near the level of the renal vessels caudally to the pelvis leads to the suspensory ligament region and is often helpful in identifying the ovary and differentiating ovarian and nonovarian masses.
了解卵巢的形态特征、韧带附着情况、卵巢与输尿管的关系以及卵巢动静脉的走行，对于在计算机断层扫描（CT）中准确识别卵巢以及区分卵巢肿块和非卵巢肿块至关重要。卵巢悬韧带将卵巢附着于盆腔侧壁，并传递卵巢动静脉。在CT上，这条韧带可表现为一条通向卵巢的线性或扇形软组织带。子宫卵巢韧带偶尔在CT上可显示为子宫与卵巢之间的一条软组织带。卵巢通常位于盆腔输尿管的前方或前内侧，而髂淋巴结则位于输尿管的外侧或后外侧。因此，卵巢肿块会将输尿管向后或后外侧推移，而大的淋巴结肿块则会将输尿管向内侧或前内侧推移。卵巢肿块可能被卵巢实质覆盖，从而揭示肿块的起源。从肾血管水平附近向尾端追踪卵巢静脉至盆腔，可到达卵巢悬韧带区域，这通常有助于识别卵巢并区分卵巢肿块和非卵巢肿块。
