CBCT comparable to MRI in classifying breast lesions
By Kate Madden Yee
Wednesday, November 30 | 3:40 p.m.-3:50 p.m. | SSM01-05 | Arie Crown TheaterResearchers at the University of Pittsburgh have found that conebeam CT (CBCT) and MRI are comparable in their ability to classify breast lesions as benign or malignant.

Study finds gadolinium-enhanced cardiac MRI often exceeded FDA guidelines
By Wayne Forrest
Tuesday, November 29 | 3:30 p.m.-3:40 p.m. | SSJ04-04 | Room S503ABA review of research from 2004 to 2010 has found that cardiac MRI studies routinely use higher gadolinium doses than recommended by the U.S. Food and Drug Administration (FDA) and clinical trials should be conducted to determine the appropriate doses of gadolinium enhancement of the myocardium.

Single dose of gadobutrol may be enough for cardiac MRI
By Wayne Forrest
Tuesday, November 29 | 3:20 p.m.-3:30 p.m. | SSJ04-03 | Room S503ABA study by Italian researchers suggests that a single dose of the MRI contrast agent gadobutrol is just as effective as a double dose of gadopentetate dimeglumine in cardiac MR imaging.

Preoperative MRI benefits surgical outcomes for breast cancer patients
By Wayne Forrest
Monday, November 28 | 3:10 p.m.-3:20 p.m. | SSE01-02 | Arie Crown TheaterThe appropriate use of preoperative MRI in selected breast cancer patients can achieve a statistically significant improvement in surgical outcome, according to a new study from researchers at Yale University School of Medicine.

3D XETA MRI trumps conventional MRI in knee imaging
By Wayne Forrest
Monday, November 28 | 3:00 p.m.-3:10 p.m. | SSE15-01 | Room E451BA new study has concluded that isotropic extended echo-train (XETA) MRI provides more information than conventional MRI on the location and stability of meniscal tears, a finding that can aid presurgical planning.

fMRI reveals altered language function in brain tumor patients
By Wayne Forrest
Monday, November 28 | 11:50 a.m.-12:00 p.m. | SSC12-09 | Room N226With the help of functional MRI (fMRI), Swiss researchers have found evidence of how patients can maintain their language function despite a tumor in the corresponding area of the brain.

MRI estimates dominant tumor volume for prostate cancer therapy
By Wayne Forrest
Monday, November 28 | 11:30 a.m.-11:40 a.m. | SSC06-07 | Room E353BMRI can accurately estimate the dominant tumor volume and provides greater accuracy in distinguishing tumors larger than 0.5 cm compared with serum prostate-specific antigen and patient age, according to a new study from the U.S. National Cancer Institute.

New MRI technique helps detect left ventricular myocardial scars
By Wayne Forrest
Monday, November 28 | 11:20 a.m.-11:30 a.m. | SSC01-06 | Room S502ABChinese researchers are giving high marks to a new free-breathing 3D phase-sensitive inversion recovery turbo FLASH pulse sequence for detecting left ventricular myocardial scars in patients with coronary artery disease.

Gadobutrol and gadofosveset contribute to contrast-enhanced MRI results
By Wayne Forrest
Monday, November 28 | 10:40 a.m.-10:50 a.m. | SSC12-02 | Room N226In patients with glioblastoma, the MRI contrast agent gadobutrol provides "significant tumor enhancement" in early postcontrast imaging, but gadofosveset offers significantly greater diagnostic information and lesion enhancement after six hours.

Endorectal MRI provides predictive biomarker for prostate cancer patients
By Wayne Forrest
Monday, November 28 | 10:40 a.m.-10:50 a.m. | SSC06-02 | Room E353BEndorectal MRI can serve as a predictive biomarker for biochemical relapse in patients undergoing combination brachytherapy and intensity-modulated radiation therapy, according to a new study by researchers at Memorial Sloan-Kettering Cancer Center.
