Remote Control MRI Feasible for Cardiovascular Patients
Images obtained by distant operator excellent in 90 percent of cases, versus 60 percent for conventional imaging
TUESDAY, Oct. 24 (HealthDay News) -- Remote control magnetic resonance imaging produces significantly more reliable images than conventional local imaging in cardiovascular procedures, researchers report in the November issue of Radiology.
J. Paul Finn, M.D., of the University of California Los Angeles, and colleagues compared the use of remote control magnetic resonance imaging on 30 cardiovascular patients with 30 images acquired through conventional local imaging. A distant operator obtained the remote images by using a personal computer and performing 1.5-T magnetic resonance vascular imaging.
The researchers compared total image quality and motion artifact in myocardial delayed enhancement, cardiac cine and magnetic resonance angiograms. They also assessed vascular definition in magnetic resonance angiograms.
The investigators found that the image quality was excellent in 38 of 42 remote images (90 percent), compared to 25 of 42 (60 percent) of the conventionally created images, while motion artifact scores were similar.
"Interactive magnetic resonance imaging was successfully implemented with remote control in complex cardiovascular cases; diagnostic quality of images was superior to that of images obtained locally," the authors write.
