The latest evolution of GE Healthcare's Signa HD x (high definition x) platform offers MR pulse sequences that overcome barriers to diagnostic scans in some difficult-to-image patients. The xt version, shown at the RSNA meeting, features two major innovations: 3D Cube and Ideal.
The latest evolution of GE Healthcare's Signa HD x (high definition x) platform offers MR pulse sequences that overcome barriers to diagnostic scans in some difficult-to-image patients. The xt version, shown at the RSNA meeting, features two major innovations: 3D Cube and Ideal. 3D Cube's capture of submillimeter isotropic voxels allows the viewing of a volumetric data set in any plane and the visualization of lesions as small as 2 mm. Ideal improves image clarity through uniform fat suppression and handling multiple contrasts from fat, water, and the two combined, both in-phase and out-of-phase. It also reduces or eliminates artifacts due to chemical shift of metal implants, such as orthopedic screws or dental work, and eliminates misregistration between fat and water.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
