       介入放射学是为经济危机下预算紧缩和让病人尽快回到日常生活所度身订造的的医学。为此，今年RSNA承诺提供最为吸引人瞩目的影像引导下的介入治疗技术，为了使介入手术更安全，更快捷，比以往任何时候更经济，并同时提供缩短住院时间 - 或者根本就不住院。

 

       无论是癌症治疗，静脉或脊椎干预，血管成像，药物疗法，或子宫肌瘤治疗，在患者排沙简金的选择治疗方法的时候，与开腹手术治疗比较介入技术的好处是巨大的。从今年的北美放射学会介入放射学相关科学报告和继续教育课程来看，最具代表的是推动创新和介入放射学的规范化。例子包括：

       肝癌切除的新技术：化学栓塞是标准的，但一个来自香港将报告指出，经动脉乙醇消融术是一种很有前途的技术，也许会提供更好的结果。

       对于一些高度血管头部和颈部肿瘤，Onyx胶栓塞比聚乙烯醇栓塞安全和更有效，这是一个来自慕尼黑团队的报告。黑色的Onyx，以及帮助肿瘤的识别。

       乳房，法国调查人员发现，他们可以活检病变他们甚至二维X线摄影看不到的病变，这是由于三维乳腺断层合成一个完整的靶活检目标。

 

       参阅会议事先透露的日程安排我们可以发现更多的是：

 

       在肝脏，例如，肝癌消融历来受到限制的是，超声无法发现更小的病灶，在时机成熟时对它们实施消融。但多个图像组合融合显像的方式可以显示病变提供射频消融治疗。

 

       经研究，来自意大利的新的实时融合影像技术，结合B超与CT或MR至找到了超声未发现的肿瘤。

       一项自墨西哥研究显示，通过RFA后立即获取的CT影像的衰减，预测肝癌射频消融术复发，

       来自加拿大的研究，显示动脉直径与动脉瘤蛛网膜下腔出血灌注之间的关联，有助于预测动脉内治疗效用

 

       北美放射学会，有很多能够看到和听到东西超出了科学的会议。甚至克林顿都将至会议发表演讲。

 

       开幕式上。放射诊断学的年度演说（ The Annual Oration in Diagnostic Radiology ）将包括评估和处理局灶性肺部病变的创新的新技术。讲演者是Christian Herold医师，维也纳大学放射科教授将在Crown Theater （周日，11月28日，PS10，:8:30 - 10：15分）。

 

       热门话题：包括质量改进项目展示将于11月29日提交一份关于病人安全的介入放射学简报（4:45时至下午4：55时，SI24C室 E353A）。

 

       其次是血管介入治疗的安全和有效性的介绍（5:15时至下午5：25日，SI24F室 E353A）。

Technical issues render US-guided HCC ablation unfeasible Sunday, November 28 | 10:45 a.m.-10:55 a.m. | SSA24-01 | Room E350 Ultrasound-guided radiofrequency ablation is one of the best options for patients with small hepatocellular carcinoma (HCC) lesions, which are often considered inoperable. But the procedure is technically unfeasible in nearly 40% of candidates for a variety of reasons, say researchers from South Korea.

CT attenuation changes after RFA predict 6-month HCC outcomes Sunday, November 28 | 10:55 a.m.-11:05 a.m. | SSA24-02 | Room E350 Patients destined to show signs of recurrence after radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) lesions reveal different CT attenuation patterns within 24 hours of the procedure, according to researchers from Mexico.

Fusion imaging system enables ablation of liver tumors undetectable at US Sunday, November 28 | 11:05 a.m.-11:15 a.m. | SSA24-03 | Room E350 A real-time fusion imaging system that combines ultrasound with CT or MRI allows liver tumors to be targeted and ablated that otherwise would not have been detected on ultrasound, according to this study to be presented on Sunday.

Risk factors predict need for eventual reintervention after aneurysm repair Sunday, November 28 | 11:15 a.m.-11:25 a.m. | SSA23-04 | Room E352 What are the chances an endovascular aneurysm repair for an abdominal aortic aneurysm will need reintervention? Using computer-aided detection, one can predict the odds before the procedure takes place -- and even better postoperatively, as soon as the patient is sewn up, say researchers from Kingston University in London.

TEA edges out TACE for ablation of unresectable HCC Sunday, November 28 | 11:45 a.m.-11:55 a.m. | SSA24-07 | Room E350 Transarterial chemoembolization (TACE) is the standard ablation method for unresectable hepatocellular carcinoma (HCC), but transarterial ethanol ablation (TEA) may gain a foothold as an alternative method due to its potential for better outcomes, Hong Kong researchers report.

Good stroke outcomes seen after forced suction thrombectomy Monday, November 29 | 3:00 p.m.-3:10 p.m. | SSE17-01 | Room N229 The Penumbra revascularization system is an excellent recanalization tool for ischemic stroke patients; however, it can't recanalize every occluded vessel. Fortunately, a simple modification of Penumbra makes it possible to recanalize many other cases, say researchers from South Korea.

CTA parameters quantify arterial narrowing in aSAH patients Monday, November 29 | 3:20 p.m.-3:30 p.m. | SSE17-03 | Room N229 In patients presenting with aneurysmal subarachnoid hemorrhage (aSAH), whole-brain CT perfusion (CTP) and CT angiography (CTA) provide baseline perfusion parameters for future comparison when CTA is performed for evaluating a suspected ruptured aneurysm, researchers will report in this Monday session.

Onyx embolization feasible, safe for head and neck tumors Monday, November 29 | 3:50 p.m.-4:00 p.m. | SSE17-06 | Room N229 For preoperative preparation of patients with highly vascularized head and neck tumors, embolization with Onyx is safe and more effective than standard preoperative endovascular embolization with polyvinyl alcohol microparticles, according to a German study.

Preoperative MRI predicts upgrade of DCIS to invasive breast cancer Tuesday, November 30 | 3:50 p.m.-4:00 p.m. | SSJ01-06 | Room E352 MRI of ductal carcinoma in situ (DCIS) can help determine which lesions are likely to upgrade to invasive cancers, researchers from New York University Medical Center in New York City will report in this Tuesday afternoon presentation.

Brachytherapy plus cryotherapy cuts lung cancer recurrence Wednesday, December 1 | 10:30 a.m.-10:40 a.m. | SSK04-01 | Room S504AB Cryotherapy is a safe and effective option for lung cancer treatment, particularly in patients with unresectable tumors. In this scientific session, researchers from China will address the high recurrence rates that can affect this treatment.

CT-guided cryoablation safe for kidney lesions Friday, December 3 | 10:30 a.m.-10:40 a.m. | SST16-01 | Room E353B There's more than one way to kill a kidney cancer without surgery. Freezing renal tumors percutaneously is safe and effective and delivers very low complication rates, say researchers from Duke University in Durham, NC.

Radiofrequency ablation safe for multifocal renal neoplasms Friday, December 3 | 10:40 a.m.-10:50 a.m. | SST16-02 | Room E353B Radiofrequency ablation is a good renal sparing alternative to surgery for patients with multifocal renal tumors, and the complication rate is no higher than for patients with single tumors, researchers from Wake Forest University Baptist Medical Center in Winston-Salem, NC, have found.
