Abstract

Background

This study evaluates the procedural efficacy and patient experience of Contrast Enhanced Mammography (CEM)-guided biopsies performed in a prone position using the Giotto Class 30,000 system. The emphasis is on the procedural advantages and clinical outcomes for “enhancing-only lesions” (EOLs).

Methods

A retrospective analysis of 524 CEM examinations conducted from December 2023 to June 2024 at a tertiary referral center was performed. Patients referred for pre-surgical staging or evaluation of inconclusive findings from conventional imaging were included. The study utilized dual-energy imaging and vacuum-assisted biopsy techniques, focusing on patients with at least one EOL identified in their initial CEM. Exclusions were based on the absence of a primary or follow-up CEM conducted at our facility Endpoints of this work included procedure efficiency which was evaluated in terms of technical success (biopsy completion with adequate sampling), dose distribution and timing and detection of additional lesions and patients’ comfort evaluation, based on the rate of complications (hematomas) and procedure interruption due to patients’ specific request or fainting events.

Results

Among the evaluated cases, 37 EOLs were biopsied. The average procedure time was 15.8 min. Biopsies were successfully completed in 100% of cases. However, complications occurred in 27% of cases, primarily as hematomas and a significant histological finding rate of 97.3% was recorded.

Conclusions

The use of the Giotto Class 30,000 system for CEM-guided biopsies in a prone position demonstrated high procedural success and was well-tolerated by patients, highlighting its potential to enhance procedural comfort and efficiency. These preliminary results validate the innovative approach, though further studies are required to solidify these findings and explore long-term outcomes.

使用俯卧台进行对比增强乳腺 X 线造影（CEM）引导活检：对一家 CEM 转诊中心初步经验的回顾性分析。

背景：本研究评估了使用Giotto 30,000级系统在俯卧位进行造影剂增强乳腺X线摄影（CEM）引导下活检的疗效和患者体验。重点是 "仅增强病变"（EOL）的程序优势和临床结果：对一家三级转诊中心在 2023 年 12 月至 2024 年 6 月期间进行的 524 次 CEM 检查进行了回顾性分析。研究对象包括因手术前分期或常规成像检查结果不确定而转诊的患者。研究采用了双能量成像和真空辅助活检技术，重点关注在初次CEM中至少发现一个EOL的患者。这项工作的终点包括手术效率，评估指标包括技术成功率（活检完成并充分取样）、剂量分布和时间、额外病变的检测以及患者舒适度评估，评估指标包括并发症（血肿）发生率以及因患者特殊要求或晕厥事件而导致的手术中断：在接受评估的病例中，37 例 EOL 接受了活组织检查。平均手术时间为 15.8 分钟。100%的病例都成功完成了活检。然而，27%的病例出现了并发症，主要表现为血肿，组织学发现率高达97.3%：结论：使用Giotto Class 30,000系统在俯卧位进行CEM引导活检的手术成功率很高，患者的耐受性也很好，突显了该系统在提高手术舒适度和效率方面的潜力。这些初步结果验证了这一创新方法的有效性，但还需要进一步的研究来巩固这些结果并探讨长期效果。
