Good stroke outcomes seen after forced suction thrombectomy
By Eric Barnes
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.

iPhone visualizes telestroke images well, but speed is slow
By Kate Madden Yee
Monday, November 29 | 11:10 a.m.-11:20 a.m. | SSC07-05 | Room S102DImage quality and accuracy of interpretation is excellent when the iPhone is used for visualizing telestroke images, but due to the device's slower speed and smaller field-of-view, it's still not up to par compared to a PACS workstation, Boston researchers report.

Perfusion brain CT performed at normal head CT doses
By Eric Barnes
Friday, December 3 | 11:10 a.m.-11:20 a.m. | SST14-05 | Room S403BIn brain perfusion CT, multiple time-resolved images are needed to track the flow of contrast through the brain, leading to higher radiation doses in the range of 300-500 mGy. But researchers from the Mayo Clinic in Rochester, MN, can do it with less radiation -- down to 75 mGy -- using a gradient adaptive bilateral filter noise reduction algorithm.

FDA: 'Improper use' of CT scanners led to perfusion overdoses
By Brian Casey
The U.S. Food and Drug Administration has released the results of its investigation into a series of radiation overdose incidents in CT brain perfusion exams. The agency said that, most likely, the incidents were not due to scanner malfunction, but rather were caused by "improper use" of the systems.

DTI-MRI and PWI-MRI can detect signs of dementia
By Wayne Forrest
Thursday, December 2 | 11:40 a.m.-11:50 a.m. | SSQ13-08 | Room N229Advanced MRI techniques, such as perfusion-weighted imaging (PWI) and diffusion-tensor imaging (DTI), may be useful in diagnosing dementia, according to a study from Wroclaw Medical University in Poland.

Dual-source RF in 3T MRI reduces spinal cord exam time
By Wayne Forrest
Tuesday, November 30 | 10:40 a.m.-10:50 a.m. | SSG10-02 | Room N226Dual-source radiofrequency (RF) transmission in 3-tesla MRI of the spinal cord reduces exam time by one-third and produces diagnostic-quality images comparable to standard single-transmission sequences, according to a new study from the University of Bonn Medical Center in Germany.
