Breast MRI wins allies, while CAD survives attack
In a flash, after the American Cancer Society guidelines came out in favor of breast MRI for high-risk screening in late March, prominent radiology preauthorization company CareCore proclaimed it had been ahead of the times. The ACS release was a major coup for the technique.
In a flash, after the American Cancer Society guidelines came out in favor of breast MRI for high-risk screening in late March, prominent radiology preauthorization company CareCore proclaimed it had been ahead of the times. The ACS release was a major coup for the technique.
CareCore, which serves more than 30 million subscribers, issued a press release in April indicating that the recommendations were in line with evidence-based policies it had established more than two years ago.
The new ACS guidelines advise annual MRI screening along with mammography for women with a high lifetime risk of breast cancer. They could apply to 1 to 1.5 million women of screening age, and the ACS stamp of approval may impress insurance companies and lead to more uniform acceptance.
Along with the ACS guidelines, breast MRI got a boost earlier in the year when a large multicenter trial found MRI extremely useful in detecting or reliably ruling out mammographically occult cancer in the contralateral breast of women recently diagnosed with cancer in one breast (NEJM 2007;356[13]:1295-1313).
As breast MRI basked in positive publicity, computer-aided detection used in breast imaging came under intense attack with the release of a retrospective study that found CAD resulted in more false positives, recalls, and biopsies and produced lower overall accuracy compared with non-CAD environments (NEJM 2007;356;14:1399-1409).
European Society of Breast Imaging Issues Updated Breast Cancer Screening Recommendations
April 24th 2024One of the recommendations from the European Society of Breast Imaging (EUSOBI) is annual breast MRI exams starting at 25 years of age for women deemed to be at high risk for breast cancer.
New Literature Review Assesses Merits of Cardiac MRI After Survival of Sudden Cardiac Arrest
April 19th 2024While noting inconsistencies with the diagnostic yield of cardiac MRI in patients who survived sudden cardiac arrest, researchers cited unique advantages in characterizing ischemic cardiomyopathy (ICM) and facilitating alternate diagnoses.
Study of Ofatumumab for Multiple Sclerosis Shows 'Profoundly Suppressed MRI Lesion Activity'
April 17th 2024The use of continuous ofatumumab in patients within three years of a relapsing multiple sclerosis diagnosis led to substantial reductions in associated lesions on brain MRI scans, according to research recently presented at the American Academy of Neurology (AAN) conference.
