The MAGiC* of complete flexibility for multiple contrast changes The new MAGiC sequence is a major innovation in neuro imaging. For the first time ever with MAGiC, clinicians have the ability to generate six contrasts in a single scan and in as little as one-third of the total time taken to acquire each contrast separately using conventional techniques. After an acquisition of only five minutes, it is now possible to adjust the image contrast in real time, even after completing the scan by simply moving a dynamic cursor to change conventional MRI acquisition parameters (TE, TR and TI) depending on the disease or the age of the patient. Dr. Ahlers stated: “In addition to all contrasts automatically provided by MAGiC, such as FLAIR, T1, T2, PD, STIR and PSIR, we scan three additional sequences includingT2* and DWI to have a comprehen- sive brain routine protocol, all in less than ten minutes.” This time saved could potentially allow clinicians to scan one more patient per hour, every hour of every day. MAGiC also pro- vides quantitative information (maps T1, T2, and proton density) which has the potential to provide new perspectives for physi- cians to characterize earlier and more precisely small or secondary lesions and monitor patients with neurodegenerative disorders. Innovative clinical applications for professional healthcare In addition to MAGiC, the SIGNA Pioneer offers several impressive advances in imaging with inno- vative applications and thus gives clinicians a high diagnostic confidence:“With SIGNA Pioneer, our goal was to improve both productivity and image quality simultaneously. We are already seeing results with inno- vativesequences.Forexampleinbodyimaging,thenewsequences DISCO and FOCUS have changed our pelvic protocol for oncology studies. We now use a FOCUS small FOV diffusion centered on the pelvic area with significantly reduced distortions especially at 3.0T. DISCO has replaced our previous DCE-MRI sequence since it allows us to achieve very high temporal resolution and very high spatial resolution simultaneously. This has helped to improve assess- ment of lesion enhancements.” He added: “The system is really built for large field of view body and spine imaging. We are able to routinely scan 50 x 45 cm coronal scans with very good image quality. In many cases it minimizes the number of stations we would need for body and spine imaging.” Improving patient experience in very challenging situations Patients with neurodegenerative disease, who cannot remain still during the examinations, will also now be able to benefit from MR. With new advanced 3D motion correction software, SIGNA Pioneer will compensate patient movement to provide the same image quality and comfort for diagnosis despite involuntary movements. An enhanced SilentScan package also considerably reduces scan noise from excess of 110 decibels (dBA) for conventional MRI scans to just three dBA above ambient noise for most head exams. This is a major differentiator for patient comfort and to minimize the risk of deteriorating image quality for the radiologist in anxious patients.“The SilentScan technology has helped us deliver a nearly noise-free neuro exam including Diffusion Weighted imaging. Our patients really appreciate it“, concluded Dr. Ahlers. www.gehealthcare.com Conventional: Six scans for six contrasts MAGiC: One scan with six contrasts (based on MAGiC neuro-protocols.
