Elastography ready for clinical routine?
December 15, 2009
The Nov. 30 release by the RSNA that highlights research indicating the potential of elastography to reduce the number of breast biopsies, might be an indication that this technique is ready for clinical routine.
At A Glance
# Elastography can help distinguish cancerous from benign breast lesions.
# Elastography has the potential to reduce unnecessary breast biopsies.
# Currently, 80 percent of breast biopsies yield benign results.

CT perfusion and radiation poisoning
December 9, 2009
Stroke imaging by CT perfusion has exposed more than 200 patients to radiation poisoning in Cedars-Sinai Medical Center in Los Angeles only. But this is just an example of a problem emerging in many medical centers. This has led the FDA authorities to issue a set of preemptive recommendations for the use of CT perfusion. The rapid developments of CT imaging in the last couple of years has led to a significant increase in CT scans, sometimes without taking into account the risks associated to radiation.

3T MRI shows correlation between sports and knee abnormalities
December 2, 2009
Some researchers from the University of California, San Francisco, have conducted a study with 236 asymptomatic patients to investigate the relationship between sports and knee abnormalities. Even, when further research is needed, the study shows a correlation between sports with high impact on the knees (running, jumping, skying) and cartilage deterioration. Of course, this is not a surprising discovery, but it shows clinical evidence of the effect of some sports on the human body: a warning for extreme sporters?
