Pediatric Patient Body Shape May Play a Key Role in Decreasing Radiation Dose During CT Scans
Manipulation of kVp (kilovoltage peak) and mAs (tube current flow) according to a patient's body shape may help reduce radiation doses in pediatric patients during CT, according to a study performed at the Cleveland Clinic Children's Hospital in Cleveland, OH. view more (2009-04-24)
'Faulty' brain connections may be responsible for social impairments in autism
New evidence shows that the brains of adults with autism are "wired" differently from people without the disorder, and this abnormal pattern of connectivity may be responsible for the social impairments that are characteristic of autism. view more (2008-06-13)
Early myocardial enhancement defects on multidetector CT predicts future myocardial viability
Early myocardial enhancement defects (dark spots) on multidetector CT are valuable predictors of myocardial viability in patients who have suffered a heart attack. view more (2006-05-03)
MRI shows brain atrophy pattern that predicts Alzheimer's
Using special MRI methods, researchers have identified a pattern of regional brain atrophy in patients with mild cognitive impairment (MCI) that indicates a greater likelihood of progression to Alzheimer's disease. The findings are published in the online edition of Radiology. view more (2009-02-10)
Diffusion Tensor Imaging Allows Radiologists to See Areas of the Brain Rarely Seen Using Other Imaging Modalities
Radiologists are now able to look at parts of the brain using diffusion tensor imaging (DTI) that are rarely visible with any other imaging method, according to a study performed at Beth Israel Deaconess Medical Center in Boston, MA.

Near 100 percent mammagraphy recall compliance costs less than a quarter per patient
The hidden costs of achieving a 99.5% mammography recall compliance rate is 16 cents per screening patient. view more (2006-05-05)
New MR Technique May Help Save Women from Unnecessary Breast Biopsies
A new MR procedure that uses diffusion-weighted imaging (DWI) to determine whether or not a breast lesion is malignant or benign may help reduce unnecessary breast biopsies, according to a study performed at the National Institute of Health in Bethesda, MD. DWI is a method that produces images detecting the exchange of water molecules between... view more... (2009-04-24)
Some benign breast lesions could be dangerous
Certain breast lesions diagnosed as benign on core needle biopsy have cancer at surgical excision and thus should be removed, according to a study appearing in the March issue of Radiology. view more (2006-02-28)
Rotator cuff treatment provides immediate tendonitis relief
A minimally invasive procedure to treat tendonitis in the rotator cuff of the shoulder provides immediate symptom relief to the patient. view more (2009-06-30)
MSU researcher studies ties between cholesterol drugs, muscle problems
A Michigan State University researcher is studying whether the most popular class of cholesterol-lowering drugs may cause muscle problems in users. view more (2008-11-12)
Informational handout key to giving parents a better understanding of CT radiation risks
Simply giving parents informational handouts can improve their understanding of the potential increased risk of cancer related to pediatric CT, according to a recent study conducted by researchers from The Children's Hospital in Denver, CO and Yale University School of Medicine in New Haven, CT. view more (2007-08-15)
Image Guided Treatment Helping Women with Tubo Ovarian Abscesses Avoid Unnecessary Surgery
Image guided drainage of tubo ovarian abscesses help women avoid surgery, according to a study performed at Massachusetts General Hospital in Boston, MA. Tubo ovarian abscesses (TOAs) are an infected collection of pus, involving a patient's fallopian tube(s) or ovaries. They can occur in patients with complicated cases of pelvic inflammatory... view more... (2009-04-24)
Stem cells speed growth of healthy liver tissue
For the first time, researchers have used adult bone marrow stem cells to regenerate healthy human liver tissue, according to a study published in the April issue of the journal Radiology. view more (2007-03-27)
Preoperative brain mapping alters tumor surgery
By pinpointing the motor and language areas of the brain with functional magnetic resonance imaging (fMRI), surgeons can target brain tumors more effectively while reducing the risk of damaging important cognitive and motor processes, according to a study appearing in the September issue of Radiology. view more (2006-08-29)
New imaging analysis predicts brain tumor survival
As early as one week after beginning treatment for brain tumors, a new imaging analysis method was able to predict which patients would live longer, researchers from the University of Michigan Comprehensive Cancer Center have found. view more (2009-04-20)
CT Scans to Determine Heart Disease in the Emergency Room
In the future, patients who arrive at a hospital Emergency Department complaining of chest pain may be diagnosed with a sophisticated CT scan. If the diagnosis is negative, the patient can go home-and the total time at the hospital will be much shorter than it is today. view more (2007-11-28)
Screening MRI allows detection of more breast cancers in high-risk women
Magnetic resonance imaging (MRI) enables radiologists to accurately identify tumors missed by mammography and ultrasound, according to a multicenter study comparing the three screening methods in women at high-risk for breast cancer. view more (2007-07-31)
New MRI technique shows emphysema in asymptomatic smokers
A new imaging method has revealed early signs of emphysema in smokers with no external symptoms of the disease, according to a study published in the June issue of Radiology. view more (2006-05-30)
Ultrasound plus mammography finds more cancers, but increases false positives
Adding ultrasound to mammography finds more cancers than mammography alone, but also substantially increases the number of false positives, according to first-year results from a three-year study of the two tests. view more (2007-10-01)
Blood flow to brain may be clue to certain dementias
The amount of blood flowing into the brain may play a larger role in the development of dementia than previously believed, according to a study in the September issue of the journal Radiology. view more (2005-08-30)
