MRIs May Increase Mastectomy in Older Breast Cancer Patients

Older breast cancer patients had significantly higher chances of mastectomy if their evaluation included a MRI, according to a study by Cary P. Gross, MD, of Yale University and colleagues.

Breast MRI was associated with an increase of more than 20% likelihood of mastectomy verses breast-conserving surgery in women 65 and older. An MRI also was associated with tripled odds of bilateral cancer diagnosis and bilateral mastectomy, as compared with age-matched patients who did not have breast MRI.

The study confirms that breast MRI detects more breast cancer lesions and better defines the extent of cancer, said Hiroyuki Abe, MD, of the University of Chicago. Consequently, a larger incision or mastectomy might follow more often.

Correlated Diffusion Imaging for Prostate Cancer Detection

Prostate cancer is one of the leading causes of cancer death in the male population. Fortunately, the prognosis is excellent if detected at an early stage. New imaging techniques can potentially be invaluable tools for improving prostate cancer detection and localization.

A new form of diffusion magnetic resonance imaging called correlated diffusion imaging (CDI) has been developed for the purpose of aiding radiologists in cancer detection and localization in the prostate gland. Preliminary results show CDI shows considerable promise as a diagnostic aid for radiologists in the detection and localization of prostate cancer.

Experimental results suggest that correlated diffusion imaging provide improved delineation between healthy and cancerous tissue and may have potential as a diagnostic tool for cancer detection and localization in the prostate gland.

MR Imaging Before US-Guided Targeted Biopsy Improves Detection Of Prostate Cancer

According to a study published in the August issue of Radiology, a Multiparametic MR imaging before a transrectal ultrasound (US)-guided targeted biopsy (TB) improves detection of prostate cancer over the standard extended systematic biopsy (SB).

TB detected 15 percent more significant cancers than SB, with those cancers going undetected had the patient not undergone prebiopsy MR imaging and TB, says Philippe Puech, MD, PhD and colleagues of the University of Lille in France.

Results showed the positivity rate for prostate cancer was 59 percent for SB and 69 percent for TB.

Low Risk Ankle Rule Can Reduce Radiography on Children

According to a study published in the Canadian Medical Association Journal, radiography on children having ankle injuries can be reduced by as much as 60% when the Low Risk Ankle Rule is used.

Radiography can reveal just 12% of fractures among children. With the help of the use of the rule, researchers found that unnecessary radiation can be reduced on these children.

Here is a resource on the Ottawa ankle rules.
