The window expands for more effective stroke treatment
May 1st 2006Buffalo psychologist Jamie Shiffner, Ph.D., beat the odds. The acute stroke patient was lucky enough to have everything go right after being struck down. With ischemic stroke, time is brain. Within moments of Shiffner's collapse at home on the evening of April 11, 2005, millions of neurons in his brain began dying every minute. The left side of Shiffner's body went numb, and attempts to talk resulted in nonsense phrases.
Study bolsters viability for MR of implanted devices
May 1st 2006MR imaging of pacemakers and implantable cardioverter devices is not for every imaging service. But the procedure is feasible, despite American College of Radiology recommendations to the contrary, according to a study from Oklahoma.
Dynamic contrast-enhanced MR imaging finally comes of age
May 1st 2006Tumors require new blood vessels in order to grow beyond a few millimeters in size. Once this "angiogenic switch" is thrown, a series of events occur that lead to the progression and spread of cancer. The vessels formed by tumors are not only larger and more numerous but also more permeable than normal vessels1 (Figure 1). Thus, when a patient with a tumor is injected with a gadolinium-chelate MR contrast agent, the tumor enhances more than the surrounding normal tissue.
MR arterial spin labeling proves feasible, safe in children
April 24th 2006High-field MR perfusion imaging with arterial spin labeling (ASL) can be performed safely and effectively on clinical pediatric populations for several neurological indications, according to Harvard University researchers.
Imaging tracks down brain’s oops! button
April 18th 2006We all make mistakes, and some cost more than others. Now, researchers have peered inside the brain to see what happens at the moment we realize our error -- and its price. Their findings may have implications for understanding obsessive-compulsive disorder.
High-field scanners assume routine clinical caseloads
April 14th 2006The market for 3T MRI is undoubtedly growing. Five years ago, few sites were using a 3T scanner for anything other than research. Now the higher field strength devices can be found in many clinical radiology departments and outpatient imaging clinics across the U.S. Clinical 3T is making inroads in Europe, too, though at a pace commensurate with its smaller MR base.
Experience overcomes difficulties of 3T MRI
April 14th 2006Whole-body MR scanners that operate at high field strengths are becoming widely available, and new 3T models have been launched in recent years. This generation of scanners offers exciting possibilities for radiological diagnosis while also posing challenges.
Manipulating brain's protective barricade can help researchers
April 14th 2006Neuroradiologists understand that high-grade tumors interrupt the blood-brain barrier, which presents as contrast enhancement on CT and MRI. Renewed interest in the phenomenon of permeability, however, has researchers looking beyond simple contrast enhancement and toward molecular mechanisms involved in permeability that may help them treat brain tumors more effectively.
Imaging genomics unveils roots of aggression
April 12th 2006An MR-based study has revealed associations between a gene variant and impulsive, violent behavior in humans, particularly males with a history of child abuse. The findings prompted National Institutes of Health director Dr. Elias A. Zerhouni to tout the power of imaging genomics to better understand brain circuitry underlying diversity in human temperament.
Report from SCBT/MR: Dynamic MR plays role in female urethra evaluation
April 4th 2006Imaging women with MR while they perform stress maneuvers can identify and characterize unsuspected pelvic organ prolapse, compared with imaging them while at rest, according to a study presented in Phoenix at the annual meeting of the Society of Computed Body Tomography and Magnetic Resonance.
Breast MR boosts detection of ductal carcinoma in situ
April 2nd 2006MR imaging has demonstrated a high sensitivity for detecting ductal carcinoma in situ, and it could play a complementary role to mammography in finding and evaluating this very common type of cancer, according to a study in The Breast Journal.
Dose concerns sway use of MR, CT in colon, brain
April 2nd 2006Among European radiologists, concerns about ionizing radiation exposure give MR an edge in specific applications, including colorectal cancer screening in younger patient populations. But in the U.S., such concerns have not dampened enthusiasm for CT, particularly in neurovascular studies.

Now the higher field strength devices can be found in many clinical radiology departments and outpatient imaging clinics across the U.S. Clinical 3T is making inroads in Europe, too, though at a pace commensurate with its smaller MR base.
Radiologic signs more than double sensitivity of MR imaging of knee
March 14th 2006Radiologists can make a more accurate preoperative diagnosis of damage to knee cartilage by using four radiologic signs, according to a study from Duke University Medical Center. Using the signs to identify the extent and type of damage to knee cartilage makes interpreting MRI with a higher degree of accuracy easier for any radiologist, regardless of level of expertise.
Breast MR boosts detection of ductal carcinoma in situ
March 13th 2006MR imaging has a high sensitivity for detecting ductal carcinoma in situ and could play a complementary role to mammography in finding and evaluating this common type of cancer, according to a study published in Breast Journal.
Whole-body PET/CT scans take on colon cancer, other new challenges
March 6th 2006A whole-body PET/CT scan can be used to stage and further pinpoint cancers spotted on optical colonoscopy, a research team for Essen University reported Monday. The team also reported that PET/CT scans may be useful in restaging recurrent breast cancer.
Study scores breast cancer imaging techniques for high-risk women
March 5th 2006A small study from a breast cancer surveillance program of high-risk women found that annual MR imaging did not detect additional cancers beyond conventional screening with both mammography and clinical physical examination.
CT, MR edge ultrasound in PVD utility, but CT wins on cost
March 5th 2006CT and MR angiography both provided more clinically useful information than duplex ultrasound in screening peripheral vascular disease. But when costs are factored in, CT emerged as the clear leader, according to a four-hospital study conducted in the Netherlands and described Saturday.
MR juggles obstacles, advantages in liver RFA guidance
March 5th 2006MR offers decided advantages as a tool for image guidance in radiofrequency ablation of liver tumors, but it also presents significant problems that must be overcome before its use becomes widespread, according to a pair of presentations March 5 at the European Congress of Radiology.
MR colonography evolves to meet screening needs
March 3rd 2006MR colonography has yet to capture radiologists’ imagination to the same extent as CT. But the radiation-free exam has a bright future, especially if stool tagging techniques can avoid the need for bowel cleansing, according to speakers from the U.S. and Greece at ECR on Friday.
