Diffusion MR technique shows promise for pediatric lung assessment
December 14th 2005Hyperpolarized helium-3 diffusion MR can detect alveolar changes due to lung disease in children and provide quantitative data on airflow to the peripheral lobes, according to research presented at the RSNA meeting.
Major pelvic joint surgery isn’t always hip
December 13th 2005Early diagnosis of femoro-acetabular impingement syndrome could prevent degenerative arthritis of the hip. It may keep young patients from potentially expensive, and possibly disastrous, invasive treatment interventions, according to research presented at the RSNA meeting.
Major pelvic joint surgery isn’t always hip
December 2nd 2005Early diagnosis of femoro-acetabular impingement syndrome could prevent degenerative arthritis of the hip. In addition, it may keep young patients from potentially expensive, and possibly disastrous, invasive treatment interventions, according to research presented at the RSNA meeting.
Real-time 'functional' DTI aids cerebral palsy patients
December 1st 2005Diffusion tensor imaging, an MR technique that produces images based on the orientation of water molecules, has mainly been used to evaluate brain white matter diseases. Now, Stanford University researchers have combined DTI with computer-generated musculoskeletal models to plan gait-correcting surgeries in children with cerebral palsy.
Strategic goals take shape in functional brain MR imaging
December 1st 2005Although neurosurgeons depend on preoperative functional MRI to map eloquent brain areas, technique standards need strengthening and reimbursement is nonexistent. The recent formation of a dedicated fMRI society is serving to galvanize interest and search for solutions to these and other issues, according to a Wednesday panel discussion.
New Horizons lecturer touts opportunities for imaging biomarkers
November 30th 2005Academic radiologists usually cut to the chase in describing how imaging increasingly factors into drug discovery and research. They display cellular metabolism FDG-PET images or dynamic-contrast MR images quantifying changes in tumor vascularity. These glamor children of radiological research reflect the potential of medical imaging in measuring therapeutic response.
Siemens introduces MR operation by remote
November 30th 2005Siemens demonstrated hands-off imaging at the RSNA with a work in progress that turns control of an MR scanner over to remote operators. The goal behind Expert-I, which is pending FDA clearance, is to allow expert collaboration on challenging examinations regardless of how far away the expert may be.

News from the RSNA meeting: Neuro-protective myelination may increase in middle age
November 28th 2005Myelination, the development of a protective sheath for nerve fibers, may dramatically increase when adults enter their forties before beginning to decline in old age, according to a study presented Sunday at the RSNA meeting. The finding contradicts long-held beliefs that myelination is a normal process of brain maturation that is largely complete by early adulthood.
MRA throws down gauntlet to DSA in neurovascular disease
November 28th 2005High-field 3D MR angiography can put up a good fight against conventional x-ray digital subtraction angiography for the diagnosis of brain aneurysms and other intracranial vascular malformations, according to studies presented at the RSNA meeting Monday. Three-D MRA also provides reliable follow-up after treatment.

MRI proves value in lymphoma staging
November 10th 2005Whole-body MRI with a nonenhanced imaging sequence can provide accurate staging of lymphoma. Contrast agents and other improvements could take this accuracy even further, making MRI an alternative to CT and PET, according to researchers at Mater Misericordiae Hospital in Dublin.
MRS gains indications, but still fights for reimbursement
November 2nd 2005To paraphrase Mark Twain, reports of the death of diagnostic MR spectroscopy are greatly exaggerated. CPT 76390 is considered standard of care as an effective imaging technique for the diagnosis, treatment, and monitoring of patients with brain lesions by Cigna Healthcare, a respected healthcare provider,1 though declared "investigational" by Blue Shield, Anthem, and Medicare. Radiologists and other physicians are confused and annoyed by some insurers' refusal to reimburse for their MRS services.
JHU ICMIC spurs advanced research
November 2nd 2005Discoveries relating to the imaging of hypoxia, angiogenesis, and ligand receptors demonstrate the scientific prowess of the In vivo Cellular Molecular Imaging Center at Johns Hopkins University and justify its reputation as one of the top molecular imaging laboratories in the world.
3T MR imaging promises to extend radiology's reach
November 2nd 2005Exquisite images of the brain, spine, body, and joints will adorn vendors' booths at the RSNA meeting, attesting to the benefits of clinical 3T. But, unlike the many ultrahigh-field MR scans that vendors have displayed in the past, most of these 3T images will come from systems designed for everyday clinical practice.
Real-time MRI catches beating fetal heart
October 24th 2005Researchers from The Children’s Hospital of Philadelphia have performed real-time functional cardiac MRI in fetuses. Theirs is the first report of this technique, which may represent an advance over the current gold standard of fetal echocardiography.
