RSNA 2011 Relections

RSNA (Radiological Society of North America) is the largest annual trade show in the world, with about 55,000 people in attendance for the 6 day event in Chicago, Illinois. The expo includes a large number of presentations and courses on science and modern radiology.

RSNA 2011’s two main themes were lower radiation dose in diagnostic radiology imaging (especially CT) and new technology. For lower dose, there was much material on tailoring a CT scan exactly to an individual patient – based on their body size, their cardiac output, their disease process, or the type of diagnostic challenge. Additionally, a lot about new iterative reconstructions in CT – both statistical and model based, was presented. Either method lowers dose a lot, but model based results in lowered radiation exposure by up to 80%.

New technology presentations and courses covered a range of topics including dual energy CT for better tissue characterization, and the combination of imaging modalities in one platform – like SPECT/CT, or PET/MR. These combined modalities may provide a better combination of disease identification plus precise localization.

In all, RSNA 2011 offered great insights and interesting presentations. Did you attend? Share your thoughts below!

RSNA 2011: Don’t Miss Out!

The RSNA 2011 conference marks the 97th Scientific Assembly and Annual Meeting. This event, the world’s premier medical meeting for radiologic professionals, is being held on November 27 through December 2 at the McCormick Place in Chicago. The annual conference includes unparalleled education and professional development, networking opportunities, and a cutting- edge technical exhibition.

I will be involved in a number of events, both as a presenter and an author. The presentations that I will be involved in include:

• Presenter- Hot Topics: Dual- Energy CT on Tuesday, November 29 from 7:15 am to 8:15 am.

• Presenter- Refresher: Mind Your Own Business! Required Business Skills for Your First Job on Thursday, December 1 from 4:30 pm- 6:00 pm.

• Author/ Participant- Gastrointestinal Series: Scientific Formal Presentation (Dual-Energy CT of Hypervascular Liver Lesions: Evaluation of Lesion Contrast-to-Noise with Different Monochromatic keV Reconstructed Images) on Monday, November 28 from 9:50 am to 10:00 am.

• Author/ Participant- ISP- Health Services, Policy, and Research- Scientific Formal Presentation (Patient Knowledge and Perceptions about Radiation from Diagnostic Imaging) on Monday, November 28 from 3:30 pm to 3:40 pm.

• Author/ Participant- Neuroradiology Series: Stroke Imaging- Scientific Formal Presentation (Changes in the Measured Size of Atherosclerotic Plaque Calcifications in Dual-Energy CT of ex Vivo Carotid Endarterectomy Specimens: The Affect of Different Monochromatic keV Image Reconstructions) on Wednesday, November 30 from 11:00 am to 11:10 am.
