摘要

导言:对比度增强乳腺 X 射线造影术(CEM)和磁共振成像(MRI)可检测出标准乳腺成像(超声波和传统乳腺 X 射线造影术)无法发现的 "纯对比度 "病变(COL)。直到最近,核磁共振成像仍是唯一可靠的活检方法。本研究介绍了澳大利亚首次使用CEM引导活检(CEMBx)的经验和教训:方法:对首批连续接受CEMBx检查的15名COL患者进行了前瞻性审计。收集了造影剂成像的指征、患者和病变特征、手术细节、辐射剂量和病理数据:15名女性的年龄在37-81岁之间(平均59岁)。造影剂成像的适应症为解决问题(3 例)、中度风险筛查(2 例)、癌症分期(9 例)和症状(1 例)。COL为非肿块(14 例)、肿块(1 例)和增强不对称(1 例)。一名患者在同一事件中对两个病灶进行了取样。所有病变均增强并成功取样,随后插入标记夹。大多数活检(87.5%)都是在乳房颅尾受压的情况下使用水平方法进行的。手术时间从 13 到 33 分钟不等(平均 22 分钟)。放射剂量与标准立体定向活检相似。三名患者在活检后出现血肿,但都不需要干预。三例患者出现夹子移位。核心活检组织病理学结果为良性(8 例)、恶性(7 例)和边缘性乳腺病变(1 例)。患者满意度很高。成像随访仍在进行中:CEMBx是MRIBx取样COL的一种快速、安全、可靠的替代方法。

Stereotactic biopsy with contrast-enhanced mammography: the initial Australian experience

Stereotactic biopsy with contrast-enhanced mammography: the initial Australian experience

Introduction

Contrast-enhanced mammography (CEM) and MRI detect ‘contrast-only’ lesions (COLs) occult on standard breast imaging (ultrasound and conventional mammography). Until recently, MRI was the only reliable method of biopsy. This study presents the first Australian experience with CEM-guided biopsy (CEMBx) and the lessons learnt.

Methods

A prospective audit of the first 15 consecutive patients who underwent CEMBx for COLs was performed. Indications for contrast imaging, patient and lesion characteristics, procedural details, radiation dose and pathology data were collected.

Results

The 15 women were aged 37–81 years (mean 59 years). Indications for contrast imaging were problem solving (n = 3), moderate risk screening (n = 2), cancer staging (n = 9) and symptoms (n = 1). The COLs were non-mass (n = 14), mass (n = 1) and an enhancing asymmetry (n = 1). For one patient, two lesions were sampled during the same event. All lesions enhanced and were successfully sampled followed by marker clip insertion. Most biopsies (87.5%) were performed with the breast in cranio-caudal compression using a horizontal approach. Procedural duration ranged from 13 to 33 min (mean 22 min). Radiation dose was similar to standard stereotactic biopsy. Post-biopsy hematomas occurred in three patients, none required intervention. Clip displacement occurred in three cases. Core biopsy histopathology results were benign (n = 8), malignant (n = 7) and a borderline breast lesion (BBL) (n = 1). Patient satisfaction rates were high. Imaging follow-up is ongoing.

Conclusions

CEMBx is a quick, safe and reliable alternative to MRIBx to sample COLs.
