Abstract

Background: Dedicated breast computed tomography (CT) is an emerging modality, but no study has compared breast lesions additionally detected on magnetic resonance imaging (MRI) with correlated CT lesions. Although there are differences between chest CT and dedicated breast CT, a preliminary evaluation would be valuable.

Purpose: To evaluate the usefulness of contrast-enhanced chest CT in evaluating additional suspicious lesions preoperatively detected on MRI in patients with breast cancer.

Material and methods: Between January 2020 and December 2021, 245 patients with breast cancer who underwent preoperative breast MRI and contrast-enhanced chest CT were included. Enhancing lesions detected on CT showing correlation with additional suspicious lesions detected on MRI were recorded as CT-correlated enhancements. The pathological findings were confirmed by subsequent percutaneous biopsy or lesion excision. The clinical and MRI features of additional suspicious lesions were compared according to the standard reference or the presence of CT-correlated enhancement.

Results: There were 96 (39.2%) additional suspicious lesions detected on preoperative breast MRI and a malignancy rate of 39.6%. Of 96 lesions, chest CT revealed correlated enhancement in 64 (66.7%) lesions, including 33 malignant lesions. Among the 32 lesions that showed no correlation enhancement on chest CT, 5 (15.6%) were malignant. Malignancy, diffusion-weighted image restriction, and fast/washout kinetics were more frequently observed in lesions with CT-correlated enhancement than in those without correlated enhancement (P < 0.001, P = 0.001, and P = 0.020, respectively).

Conclusion: When evaluating MRI-detected additional suspicious lesions in patients with breast cancer, lesions with CT-correlated enhancement were significantly more likely to be malignant than those without CT-correlated enhancement.

胸部CT在女性乳腺癌MRI附加可疑病灶诊断中的应用。
背景:专门的乳腺计算机断层扫描(CT)是一种新兴的模式,但没有研究将磁共振成像(MRI)检测到的乳腺病变与相关的CT病变进行比较。尽管胸部CT和专用乳腺CT存在差异,但初步评估是有价值的。目的:评价胸部增强CT对乳腺癌患者术前MRI发现的其他可疑病变的评价价值。材料与方法:2020年1月至2021年12月,纳入245例术前行乳腺MRI和胸部增强CT检查的乳腺癌患者。CT上发现的增强病变与MRI上发现的其他可疑病变相关,记录为CT相关增强。病理结果经随后的经皮活检或病变切除证实。根据标准对照或有无ct相关增强,比较附加可疑病灶的临床及MRI特征。结果:术前乳腺MRI附加可疑病灶96个(39.2%),恶性率39.6%。96个病灶中64个(66.7%)胸部CT显示相关增强,其中恶性病灶33个。32例胸部CT无相关增强病灶中,恶性病灶5例(15.6%)。恶性肿瘤、弥散加权图像限制和快速/冲洗动力学在ct相关增强的病变中比在没有相关增强的病变中更常见(P分别= 0.001和P = 0.020)。结论:在评估乳腺癌患者mri检测到的附加可疑病灶时,有ct相关增强的病灶的恶性可能性明显高于没有ct相关增强的病灶。
