Dr. Russell N. Low, medical director of Sharp and Children's MRI Center in San Diego, enrolled 17 women and seven men with primary malignancies of the ovaries, colon, pancreas, breast, bladder, and gastrointestinal tract. Patients underwent preoperative abdominal and pelvic MR scanning at 1.5T. A site-by-site comparison of DWI, MRI, and combined DWI/MRI results with surgical and biopsy evaluations underscored the advantage of using DWI and MRI together.
Diffusion-weighted imaging can significantly improve the accuracy of conventional MR imaging of peritoneal metastases, according to a study released at the 2007 ISMRM meeting.
Dr. Russell N. Low, medical director of Sharp and Children's MRI Center in San Diego, enrolled 17 women and seven men with primary malignancies of the ovaries, colon, pancreas, breast, bladder, and gastrointestinal tract. Patients underwent preoperative abdominal and pelvic MR scanning at 1.5T. A site-by-site comparison of DWI, MRI, and combined DWI/MRI results with surgical and biopsy evaluations underscored the advantage of using DWI and MRI together.
DWI/MRI identified 141 of 153 sites of confirmed peritoneal tumor, with a sensitivity, specificity, and accuracy of 92%, 92%, and 93%, respectively, compared with 78%, 86%, and 82% for MRI alone. DWI bolstered readers' confidence in 75% of the cases and uncovered additional lesions in 63% of them.
What a New Mammography Study Reveals About BMI, Race, Ethnicity and Advanced Breast Cancer Risk
December 8th 2023In a new study examining population attributable risk proportions (PARPs) based on data from over three million screening mammography exams, researchers found that postmenopausal Black women had the highest BMI-related PARP and premenopausal Asian and Pacific Islander women had the highest breast density-related PARP for advanced breast cancer.
Study: Contrast-Enhanced Mammography Changes Surgical Plan in 22.5 Percent of Breast Cancer Cases
December 7th 2023Contrast-enhanced mammography detected additional lesions in 43 percent of patients and led to additional biopsies in 18.2 percent of patients, over half of whom had malignant lesions, according to a study of over 500 women presented at the recent Radiological Society of North America (RSNA) conference.
