GE updates Signa platform
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.
Can MRI Have an Impact with Fertility-Sparing Treatments for Endometrial and Cervical Cancers?
January 9th 2025In a literature review that includes insights from recently issued guidelines from multiple European medical societies, researchers discuss the role of magnetic resonance imaging (MRI) in facilitating appropriate patient selection for fertility-sparing treatments to address early-stage endometrial and cervical cancer.
Surveillance Breast MRI Associated with Lower Risks of Advanced Second Breast Cancers
January 8th 2025After propensity score matching in a study of over 3,000 women with a personal history of breast cancer, researchers found that surveillance breast MRI facilitated a 59 percent lower risk in advanced presentations of second breast cancers.
Abbreviated MRI for Hepatocellular Carcinoma: What a New Meta-Analysis Reveals
January 6th 2025For hepatocellular carcinoma screening, a 19-study meta-analysis found the abbreviated MRI sequencing protocol of T2-weighted MRI, diffusion-weighted imaging (DWI) and hepatobiliary phase (HBP) imaging offered 88 percent sensitivity and 93 percent specificity.
New CT and MRI Research Shows Link Between LR-M Lesions and Rapid Progression of Early-Stage HCC
January 2nd 2025Seventy percent of LR-M hepatocellular carcinoma (HCC) cases were associated with rapid growth in comparison to 12.5 percent of LR-4 HCCs and 28.5 percent of LR-4 HCCs, according to a new study.
