我们的目的是回顾性评价使用实时虚拟超声（RVS）检测常规B型（cB型）隐性磁共振成像（MRI）检测到的乳腺病变的二次超声（US）的实用性。在2011年7月至2015年5月期间，53例连续患者接受了二次超声检查，以识别俯卧位MRI检测到的病变，并入组本研究。在额外的仰卧位MRI后，对cB模式隐匿性MRI检测到的乳腺病变进行了使用RVS的二次查看US。在这53名患者中，59处病变最初通过俯卧位MRI检测到，随后进行二次查看US。在59处病变中，20处（34%）通过使用cB模式的二次查看US识别。在39例（66%）cB模式隐匿性病变中，38例（97%）在仰卧位MRI中检出，33例（85%）在使用RVS的二次查看US中检出。MRI形态学分型：肿块型16个，非肿块强化型5个，病灶型12个。超声引导下RVS活检或切除活检证实，33个病灶中，8个（24%）为恶性，其余25个（76%）为良性。共53例（90%）MRI检测到的病变使用cB模式和RVS进行超声识别（p < 0.001）。其余5个超声隐匿性病灶在使用RVS在乳房表面标记增强区域后，可在RVS下进行随访。尽管还需要进一步的前瞻性研究，但我们的初步研究结果表明，使用RVS进行二次超声检查并附加仰卧位MRI可能会提高cB模式隐匿性MRI检测到的乳腺病变的超声和组织病理学检出率。（电子邮件：snakano1@aichi-med-u.ac.jp）（C）2017年世界医学和生物学超声联合会。
Our aim was to retrospectively evaluate the utility of second-look ultrasound (US) using real-time virtual sonography (RVS) for detection of conventional B-mode (cB-mode) occult magnetic resonance imaging (MRI)-detected breast lesions. Between July 2011 and May 2015, 53 consecutive patients who underwent second-look US to identify lesions detected by prone MRI were enrolled in this study. Second-look US using RVS was performed for cB-mode occult MRI-detected breast lesions after an additional supine MRI. In the 53 patients, 59 lesions were initially detected by prone MRI, followed by second-look US. Of the 59 lesions, 20 (34%) were identified by second-look US using cB-mode. Of the 39 (66%) cB-mode occult lesions, 38 (97%) were detected in supine MRI and 33 (85%) were detected by second-look US using RVS. MRI morphology types of the 33 lesions were as follows: mass, 16; non-mass enhancement, 5; and focus, 12. US-guided biopsy under RVS or excisional biopsy demonstrated that of the 33 lesions, 8 (24%) were malignant and the remaining 25 (76%) were benign. A total of 53 (90%) MRI-detected lesions were sonographically identified using both cB-mode and RVS (p < 0.001). All five remaining US-occult lesions could be followed up under RVS after the enhancing area was marked on the breast surface using RVS. Although further prospective studies are required, the findings of our pilot study suggest that second-look US using RVS with additional supine MRI may improve the sonographic and histopathologic detection rate of cB-mode occult MRI-detected breast lesions.
