Article Synopsis
- The study evaluated the effectiveness and precision of freehand biopsies on various tissues using different MRI imaging techniques at a 1.0 tesla open MRI.
- Twenty-six biopsies were successfully conducted on 23 patients using MR-compatible biopsy tools, with continuous imaging making all lesions visible during the process.
- Results indicated that specialized imaging sequences improved the targeting of moving and static organs, with no adverse events or complications reported during the procedures.
Purpose: To evaluate the diagnostic performance and inter-reader reliability of the multiparametric magnetic resonance imaging (mpMRI) based prostate imaging reporting and data system (PI-RADS) version 1 and version 2 for the assessment of prostate cancer.
Material And Methods: A cohort of 82 patients underwent endorectal mpMRI at 1.5T.
Article Synopsis
- The study used an ex vivo bovine liver model to assess the effectiveness of magnetic resonance (MR) imaging in measuring the volume of non-viable tissue after radiofrequency ablation (RFA).
- Sixty-four liver specimens underwent RFA under controlled conditions, and two different MR sequences were used to determine tissue changes compared to manual dissections.
- Results showed that MR volumetry detected only a portion of the necrotic tissue, indicating that traditional MR imaging may underestimate the ablated volume, but there was a strong correlation between the MR measurements and actual volumes calculated from dissections.
Purpose: Different techniques for magnetic resonance-guided lumbar interventions have been introduced in recent years. Appropriate pulse sequence design is crucial since high spatial resolution often comes at the cost of lower temporal resolution. The purpose of this study was to evaluate the value of accelerated reduced field of view (ZOOM)-based imaging sequences for lumbar interventions.

Materials And Methods: MWA volumes were created in 50 cuboid ex vivo bovine liver specimens (five series: control [no injection], 10 mL water, 10 mL 0.9% NaCl, 10 mL 6% NaCl, and 10 mL 12% NaCl preinjections; n=10 for each series).
