�3T MRI is better at detection and characterizing structural brainiac abnormalities in patients with focal epilepsy than 1.5T MRI, stellar to a better diagnosis and safer treatment of patients, according to a recent study conducted at the Oregon Health and Science University in Portland, OR. "Patients with focal epilepsy throw recurrent seizures that resolution from a specific arena of their brain, ordinarily due to a structural brain irregularity," said Bronwyn E. Hamilton, MD, senior author of the study.
3T MRI detected 65 of 74 cases, compared to 55 of 74 cases detected by 1.5T MRI; lesions were accurately characterized in 63 of 74 cases victimisation 3T MRI, compared to 51 of 74 cases using 1.5T MRI. "Detection refers to lesions that were ground and enactment refers to how accurately we were able to determine what type of abnormality the lesion was, such as tumor versus vascular deformity versus inborn deformity," said Dr. Hamilton.
Epilepsy is a disease with serious consequences for patients and fellowship. Surgery offers the potential drop for long term cure in patients, but "surgery can only when be performed in patients who have a specific structural mental defectiveness in the brain that is detected on an imaging study (usually MRI); since insurance companies english hawthorn not pay for a second scan, it is preferable to obtain a 3T MRI the first go round," said Dr. Hamilton.
"I, and most of my radiology colleagues, in conjunction with the neurologists who specialize in epilepsy at our institution, feel that a patient with focal epilepsy is incompletely assessed without a 3T MRI, and will re-image patients with prior negative 1.5T MRI in order to feel more certain an abnormality has not been lost. We have had a number of patients world Health Organization had departed undiagnosed with prior negative MRI scans who later underwent 3T MRI at our creation that either disclosed a structural mastermind abnormality or better characterized it for the operating surgeon," said Dr. Hamilton.
This survey appears in the September issue of the American Journal of Roentgenology.
About ARRS
The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began issue in 1906. Radiologists from all all over the populace attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the battlefield of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm R�entgen, world Health Organization discovered the x-ray in 1895.
