Contrast-enhanced (CE) T1 FLAIR tops CE T1 spin echo in the spine
By Wayne Forrest
Sunday, November 29 | 11:35 a.m.-11:45 a.m. | SSA16-06 | Room N228Researchers at M. D. Anderson Cancer Center in Houston have found that T1 fluid-attenuated inversion recovery (FLAIR) postcontrast imaging of the spine can significantly improve cerebrospinal fluid suppression and increases the conspicuity of bone lesions, disk herniations, and epidural metastasis.

MRI at 3-tesla advances treatment for upper extremity nerves
By Wayne Forrest
Sunday, November 29 | 11:35 a.m.-11:45 a.m. | SSA14-06 | Room E450AResearchers at the Medical University of Vienna are using 3-tesla MRI to assess the structure and function of peripheral nerves. Their study shows that advanced 3-tesla imaging methods, such as diffusion tensor imaging and tractography, could add valuable information to the treatment of various peripheral nerve conditions.

Lack of self-referral hurts radiologists' post-DRA volume
By Wayne Forrest
Wednesday, December 2 | 3:40 p.m.-3:50 p.m. | SSM12-05 | Room S102DIf there was any doubt how the Deficit Reduction Act (DRA) of 2005 would affect procedure volume for radiologists, researchers at Thomas Jefferson University in Philadelphia have confirmed that private-office imaging volume decreased 2% in 2007, reversing annual growth of 8.4% from 2002 to 2006.

Change in contrast and new administration policies eliminates NSF
By Wayne Forrest
Wednesday, December 2 | 11:50 a.m.-12:00 p.m. | SSK11-09 | Room S102DA change from gadodiamide to gadobenate dimeglumine and gadopentetate dimeglumine contrast agents and the adoption of more restrictive policies for administering gadolinium-containing contrast has helped two U.S. universities eliminate cases of nephrogenic systemic fibrosis (NSF).

Reporting MRI exams: The positive impact of audits
By Cynthia E. Keen
Tuesday, December 1 | 3:30 p.m.-3:40 p.m. | SSJ11-04 | Room S102DWhat's the value and impact of a regular, robust clinical audit of the quality of radiology reports? An impressive improvement in quality, according to the experience of a U.K. audit program.

MRI outperforms ultrasound for fetuses with ventriculomegaly
By Cynthia E. Keen
Tuesday, December 1 | 3:20 p.m.-3:30 p.m.| SSJ10-03 | Room E351Harvard Medical School researchers have found that MRI adds useful information for fetuses with ventriculomegaly, but it does not predict outcome any better than atrial diameter, except for ventricular volume, in cases of mild, isolated ventriculomegaly.

Researchers develop rhyming paradigm to improve fMRI results
By Wayne Forrest
Tuesday, December 1 | 11:50 a.m.-12:00 p.m. | SSG15-09 | Room N229Researchers at the Cleveland Clinic's Imaging Institute have developed a new rhyming paradigm for children and adults with special needs to improve functional MRI (fMRI) activation and behavioral performance.

BRCA1 carriers benefit from combo of FFDM and breast MRI
By Kate Madden Yee
Tuesday, December 1 | 11:30 a.m.-11:40 a.m. | SSG09-07 | Room S102DFor BRCA1 carriers, a combination of full-field digital mammography (FFDM) and breast MRI for annual screening exams is the most clinically effective strategy, according to researchers from Massachusetts General Hospital in Boston.

DWI proves somewhat beneficial with bladder cancer patients
By Wayne Forrest
Monday, November 30 | 3:40 p.m.-3:50 p.m. | SSE11-05 | Room E353BWhile diffusion-weighted imaging (DWI) might be useful to depict extravesical lesions from bladder cancer, Japanese researchers say other imaging scans are required to eliminate false positives.

MRI: A 'reliable' predictor of giant cell bone tumors
By Wayne Forrest
Monday, November 30 | 10:50 a.m.-11:00 a.m. | SSC11-03 | Room E450BIf you're looking for a reliable predictor of recurrence of giant cell bone tumors, MRI is a much more effective modality than plain radiographs, according to Korean researchers at Seoul National University Hospital.

Preoperative MRI can predict clinical outcome after arthroscopic partial meniscectomy
By Wayne Forrest
Monday, November 30 | 10:30 a.m.-10:40 a.m. | SSC10-01 | Room E450APreoperative MRI can be most useful in predicting clinical outcomes after arthroscopic partial meniscectomy in middle-aged and elderly patients, according to researchers from the University of Wisconsin Hospital in Madison.

Half-dose gadolinium MR contrast comparable to full dose
By Wayne Forrest
Monday, November 30 | 10:30 a.m.-10:40 a.m. | SSC11-01 | Room E450BAmid concerns about a link between gadolinium-based MR contrast agents and nephrogenic systemic fibrosis in renal-impaired patients, researchers at M. D. Anderson Cancer Center have found that reduced or half-dose contrast enhancement of musculoskeletal lesions may be equivalent to full dose, allowing for cost savings and greater patient safety.
