Road to RSNA 2010: Interventional Radiology Preview

This year's RSNA 2010 scientific sessions reflect the energy that is driving innovation in interventional radiology, with topics ranging from breast biopsy with 3D digital breast tomosynthesis to CT-guided cryoablation for kidney lesions to a novel fusion imaging system for ablation of liver tumors.

Radiofrequency ablation safe for multifocal renal neoplasms

Friday, December 3 | 10:40 a.m.-10:50 a.m. | SST16-02 | Room E353BRadiofrequency 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.

CT-guided cryoablation safe for kidney lesions

Friday, December 3 | 10:30 a.m.-10:40 a.m. | SST16-01 | Room E353BThere'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.

Brachytherapy plus cryotherapy cuts lung cancer recurrence

Wednesday, December 1 | 10:30 a.m.-10:40 a.m. | SSK04-01 | Room S504ABCryotherapy 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.

Preoperative MRI predicts upgrade of DCIS to invasive breast cancer

Tuesday, November 30 | 3:50 p.m.-4:00 p.m. | SSJ01-06 | Room E352MRI 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.

Wide variations in left atrial anatomy seen in ablation patients

Tuesday, November 30 | 3:00 p.m.-3:10 p.m. | SSJ05-01 | Room S504ABLeft atrial anatomy is highly variable between patients, and this variability can affect the ablation strategy, according to John Hare and colleagues from the University of Wisconsin School of Medicine and Public Health in Madison.

Breast biopsies successful with integrated 3D digital breast tomosynthesis

Tuesday, November 30 | 3:00 p.m.-3:10 p.m.| SSJ01-01 | Room E352French researchers using 3D digital breast tomosynthesis are finding lesions that can't be visualized on conventional 2D mammography, and by integrating a tomosynthesis biopsy unit, they say they can biopsy and analyze a broader range of breast lesions compared with 2D digital mammography.

November 18, 2010

Onyx embolization feasible, safe for head and neck tumors

Monday, November 29 | 3:50 p.m.-4:00 p.m. | SSE17-06 | Room N229For 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.

CTA parameters quantify arterial narrowing in aSAH patients

Monday, November 29 | 3:20 p.m.-3:30 p.m. | SSE17-03 | Room N229In 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.

Good stroke outcomes seen after forced suction thrombectomy

Monday, November 29 | 3:00 p.m.-3:10 p.m. | SSE17-01 | Room N229The 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.

TEA edges out TACE for ablation of unresectable HCC

Sunday, November 28 | 11:45 a.m.-11:55 a.m. | SSA24-07 | Room E350Transarterial 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.

November 18, 2010

Risk factors predict need for eventual reintervention after aneurysm repair

Sunday, November 28 | 11:15 a.m.-11:25 a.m. | SSA23-04 | Room E352What 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.
