Fusion imaging is an accepted method in abdominal imaging allowing a simultaneous display of reference imaging with a live ultrasound (US) investigation. For prostate cancer, promising results have been published for endorectal US (ERUS)-guided biopsy of suspicious lesions in magnetic resonance imaging (MRI). To our knowledge, no other indication for the fusion of ERUS with MRI has been reported so far.
We report on three patients scheduled for ERUS due to anorectal fistulae after treatment (n = 2) or rectal carcinoma (n = 1), which were scheduled for real-time virtual onography (RVS), a method for the fusion of MRI imaging with US.
In all patients, RVS was successful. The course of the fistulae could be defined and the success of the treatment could be confirmed. In the patient with rectal carcinoma, the lymph nodes suspicious in MRI could be identified.
MRI/ERUS fusion has the potential for follow-up of anorectal fistulae and abscesses, and staging of anal and rectal tumors.
融合成像在腹部成像中是一种公认的方法，可将参考成像与实时超声（US）检查同时显示。对于前列腺癌，磁共振成像（MRI）中经直肠超声（ERUS）引导下对可疑病变进行活检已发表了有前景的结果。据我们所知，目前尚无其他关于ERUS与MRI融合的适应证报道。
我们报告了3例因治疗后肛瘘（2例）或直肠癌（1例）而计划进行ERUS检查的患者，他们计划接受实时虚拟超声造影（RVS），这是一种将MRI成像与US融合的方法。
所有患者的RVS均成功。瘘管的走行得以明确，治疗效果得到确认。在直肠癌患者中，MRI中可疑的淋巴结得以识别。
MRI/ERUS融合在肛瘘和脓肿的随访以及肛管和直肠肿瘤的分期方面具有潜力。
