Radiologists retain MRI turf, for now
CHICAGO - Although turf in-roads have been made on many high-end imaging procedures traditionally performed by radiologists, MR imaging is still the purview of the specialty, according to data presented this week at the 2005 RSNA meeting.  
MRI immediately post MI yields important prognostic clues
CHICAGO - If you're looking for microvessel obstruction in patients with acute myocardial infarction, it's worth the rush to perform cardiac MRI within 48 hours after the event -- and within two minutes of injecting the contrast. You could potentially help your patients live longer.  
Personalized training of mammo decision support tool unnecessary
CHICAGO - Customized training of a probabilistic system used in mammography decision support yields no significant difference in the system's diagnostic performance, according to research presented Thursday at the 2005 RSNA meeting.  
Fine-needle aspiration biopsy useful for smallest lung nodules
CHICAGO - In the RSNA's interventional lung session on Wednesday, Dr. Demetris Patsios from the Mount Sinai Hospital in Toronto, Canada, presented a study on the efficacy of MDCT-guided fine-needle aspiration biopsy (FNAB) of subcentimeter nodules, concluding that FNAB is a useful tool, if less accurate than FNAB of larger lesions.  
fMRI study illustrates caffeine boost in brain activity
CHICAGO - A new study using functional magnetic resonance imaging (fMRI) shows why many of us get a boost from caffeine. The results were presented Wednesday at the 2005 RSNA conference.  
MRI can't replace x-ray for pediatric growth plate injuries
CHICAGO - Investigators from Germany sought to determine if MRI could supplant x-ray in accurately diagnosing epiphyseal injuries due to fracture. They reported their results in a presentation at the 2005 RSNA meeting on Wednesday.  
Contrast-enhanced ultrasound aids in grading liver disease
CHICAGO - Contrast-enhanced hepatic ultrasound could help grade the severity of liver disease, according to research presented Wednesday at the 2005 RSNA meeting.  
DTI scans track schizophrenia-like changes in brains of teen marijuana users
CHICAGO - Based on diffusion tensor imaging (DTI) brain scans, adolescents who are genetically at risk for schizophrenia may increase that risk with heavy use of marijuana, researchers reported in a presentation Wednesday at the 2005 RSNA conference.
