In patients with a diagnosis of Cushing disease in whom magnetic resonance imaging (MRI) shows either no abnormalities or nonspecific abnormalities, surgery is preferable to medical treatment, according to study results published in The Journal of Clinical Endocrinology & Metabolism. There is a consensus that the first line of treatment for Cushing disease is transsphenoidal surgery to remove the pituitary adenoma causing the disease, with an 80% remission rate following the intervention. However, in the absence of clear evidence of a pituitary adenoma on imaging, there is some contro
The U.S. Food and Drug Administration has approved the clinical use of a magnetic resonance imaging (MRI) scanner — the ultra-high-field 7T Terra MRI — with unprecedented resolution that allows for more reliable images of the brain. The approach recently allowed the precise localization of a small tumor in the pituitary gland, which standard MRI had failed to spot, in a patient with Cushing’s disease. So far, only one scanner of this kind exists in the U.S.. It was installed in February 2017 at the Mark and Mary Stevens Neuroimaging and Informatics Institute (INI) of the Keck School
A noninvasive 7 Tesla MRI scanner at University of Southern California is the first 7T scanner to be used on a patient with Cushing's disease in the U.S., according to a USC news release. When a brain tumor was found to be "MRI-negative" in a 28-year-old female patient, physicians at the USC's Pituitary Center were unsatisfied with the results. After deciding to use the Neuroimaging and Informatics Institute's (INI) new ultrahigh field 7 Tesla MRI scanner to localize the tumor, the patient was officially diagnosed with Cushing's disease and researchers were finally able to see the tumor
