Feasibility of high spatiotemporal resolution for an abbreviated 3D radial breast MRI protocol

Abstract

The STELLR reconstruction approach of 3D radial sampling with mask subtraction provides a high-performance imaging technique for characterizing enhancing structures within the breast. It is capable of maintaining temporal fidelity, while visualizing breast lesions with high detail over a large FOV to include both breasts.

Characterization of Sub‐1 cm Breast Lesions Using Radiomics Analysis

“…Traditionally dynamic imaging in the breast has always involved a compromise between the competing requirements of high temporal resolution to appropriately sample the rapid contrast uptake observed and high spatial resolution for detailed lesion morphology. As under sampling techniques, such as compressed sensing, become more widely available, and indeed applied to breast imaging, the improved spatial and temporal resolution afforded by these methods have the potential to provide advances in diagnosis, including for small lesions. Higher spatial resolution while maintaining sufficient temporal resolution for pharmacokinetic modeling should enable greater perception of lesion morphology and enhancement characteristics both visually and quantitatively via texture and pharmacokinetic analysis.…”

Abbreviated MRI of the Breast: Does It Provide Value?

“…This approach allowed the assessment of lesion morphology and early‐phase perfusion with a total scan time of only 6 minutes. The authors conclude that upon further validation, this technique may translate to high‐performance, rapid breast cancer screening with MRI …”

“…Most recently, Jimenez et al developed a volumetric imaging technique with 0.8‐mm isotropic resolution and 10‐s/volume rate for breast cancer using parallel imaging and spatial compressed sensing. This approach allowed the assessment of lesion morphology and early‐phase perfusion with a total scan time of only 6 minutes.…”

“…The authors conclude that upon further validation, this technique may translate to highperformance, rapid breast cancer screening with MRI. 21 Oldrini et al evaluated time-resolved imaging of contrast kinetics (TRICKS) acquisitions compared with an abbreviated as well as a full diagnostic protocol. 23 The authors achieved an improved specificity when TRICKS acquisitions were added to the abbreviated protocol, outperforming the full protocol.…”

“…In efforts to overcome these limitations and facilitate increased access to screening breast MRI, Kuhl et al initially introduced an abbreviated breast MRI protocol for screening that substantially shortened examination and reading times; at the same time, this protocol maintained a diagnostic accuracy equivalent to a full diagnostic protocol . Thereafter, several other studies have investigated different abbreviated and high‐temporal resolution MRI protocols for breast cancer diagnosis and screening, with similar results . This review will provide an overview of the current published literature on abbreviated breast MRI and its potential clinical applications and challenges.…”
