In comparison to native 64-mT MRI, the deep learning generative model LowGAN offered enhanced white matter lesion conspicuity and image quality in a study involving patients with multiple sclerosis.
Electronic brain atlases emerge as clinical and educational tool
May 26th 2010The topic of electronic brain atlases was first discussed in Diagnostic Imaging Asia Pacific almost a decade ago (see “Electronic brain atlases show value in brain studies,” June 2001, page 35). The article featured four atlases and addressed the potential of this innovation.
Of skin-colored gowns and brain MRI
May 5th 2010Every so often you come across an idea that has so much merit you can’t imagine why somebody hadn’t come up with it before. Such is the case with hospital gowns matched to a patient’s skin color. Although sky blue and forest green might be stunning on the right patient, it is hard to imagine either one helping docs spot signs of diseases that can be found in skin color changes.
64-row CTA tops DSA in brain aneurysm detection
November 2nd 2009Thanks to a near-perfect performance in a large cohort study in China, 64-slice CT angiography has shown it could replace digital subtraction angiography as the modality of choice for detecting suspected brain aneurysms at risk of spontaneous subarachnoid hemorrhage.
Sixty-four-slice CTA outperforms DSA for brain aneurysm detection
October 5th 2009Thanks to a near-perfect performance in a large cohort study in China, 64-slice CT angiography has shown it could replace digital subtraction angiography as the modality of choice for detecting suspected brain aneurysms at risk of spontaneous subarachnoid hemorrhage.
Incidental finding on MRIpoints to multiple sclerosis
February 1st 2009An incidental finding of multiple sclerosistypelesions during brain MRI is no fluke. Anew study has found that some patientsdevelop the physical symptoms of the diseasewithin five years of the abnormalities'discovery on MRI.
Incidental finding on MRI points to multiple sclerosis
December 19th 2008An incidental finding of multiple sclerosis-type lesions during brain MRI is no fluke. A new study has found that some patients develop the physical symptoms of the disease within five years of the abnormalities’ discovery on MRI.
fMRI links defective brainwiring, high risk of obesity
December 1st 2008Women with a weakened brain "reward circuitry" are at increased risk of weight gain over time and potential obesity, according to two studies from researchers at the University of Oregon. The risk increases for women who also have a gene associated with compromised dopamine signaling in the brain.
Brain blood flow plays role in fibromyalgia symptoms
November 6th 2008In a potential breakthrough study, French researchers used SPECT to identify brain abnormalities that present physiological evidence of fibromyalgia. The results quash the idea that diffuse, sometimes debilitating pain from the condition stems from anxiety and depression.
Brain MR identifies youth prone to aberrant behaviors
September 9th 2008Cerebral blood flow imaging may eventually help identify young people who need preventive therapy Adolescents at relatively high risk for depression and alcohol abuse demonstrate distinct patterns of resting cerebral blood flow in areas of the brain associated with emotional behavior and decision making, according to preliminary results from the Research Imaging Center at the University of Texas Health Science Center in San Antonio.
Intraoperative angio proves worth for brain surgery
August 1st 2008Results from a decade-long study at the National Brain Aneurysm Center in St. Paul, MN, indicate that angiography to monitor intracranial brain aneurysm clip placement is safe and has altered management in more than one of 10 cases.
MR brain mapping assesses response to glioma therapy
August 1st 2008Functional diffusion technique shortens time needed to determine treatment efficiency, make adjustments The first three months after standard radiation therapy for a brain tumor must be hell for patients and their families. The established MacDonald criteria for assessing treatment force them to wait up to 10 weeks for follow-up CT or MR to determine whether the treatment is working.
MRS links fibromyalgia pain to changes in brain molecule
June 3rd 2008A new study from the University of Michigan featuring proton MR spectroscopy has found a key linkage between the widespread muscle pain, tenderness, and fatigue associated with fibromyalgia and brain glutamate. Findings could lead to new drugs to treat the condition, researchers said.
Brain stays cool as jazz man jams
May 1st 2008To the listener, jazz improvisation is an aural flight of fancy, borne aloft by a musician's on-the-spot skill and imagination. But functional MRI results show the brain actually follows a grounded process of activation and deactivation during these spontaneous musical riffs, according to researchers from the National Institutes of Health and Johns Hopkins University.
Brain and spine imaging benefit from increased field strength
April 30th 2008Neuroimaging with MRI at 3T is superior for nearly every application in the brain and spine, and it is certainly inferior for none. The technique has unique strengths for performing vascular work and functional brain imaging, but there is nothing that a 3T MR scanner can't do better than a 1.5T machine.
Follow-up care of incidental brain findings draws criticism
January 10th 2008The number of brain MR scans obtained in the clinical and research setting increases each year, as scanner equipment and scanning protocols become ever more sensitive to subtle abnormalities. Many of these incidental findings are low risk and do not need rigorous imaging follow-up. Researchers therefore suggest revising management guidelines with an eye toward less radiological intervention.
256-slice scanner captures heart, brain in single rotations
October 1st 2007The wide area detector onboard Toshiba's 256-slice CT records subtle changes in blood flow and minute blockages in single acquisitions of the brain and heart with substantially reduced risk of motion artifact and at less radiation dose to the patient.
