“…There are many types of 3D high resolution sequences including 3D Gradient Echo with destruction of the residual transverse magnetization (VIBE), balanced steady-state free precession sequence (TRUEFISP), Dual Echo steady state gradient echo sequence (DESS), gradient echo sequence where multiple echoes are collected from a single excitation (MEDIC) and 3D spin echo Sampling Perfection with Application optimized Contrasts using different flip angle Evolutions (SPACE) [6][7][8][9].…”

Purpose: To compare 3D high-resolution MRI sequences in term of contrast, Signal to Noise Ratio (SNR), artefacts and cartilage thickness in knee articular cartilage at 1.5 T. Materials and methods: Fourteen healthy volunteers and seven patients underwent articular knee cartilage exam. The 3D sequences were VOLUME Imaging with Body Enhancement (VIBE), True Fast Imaging with Steady-state Precession (TRUEFISP), Dual Echo Steady State (DESS), Multi Echo Data Image Combination (MEDIC) and Sampling Perfection with Application optimized Contrasts using different flip angle Evolutions (SPACE). For all 3D sequences, we measured contrast ratio between cartilage-bone and cartilage-meniscus, SNR and cartilage thickness. In addition, we quantified magnetic susceptibility and flow artifacts. Statistical analyses were performed using the t-test and P<0.005 was considered statistically significant. Results: Statistical results were significantly different (p>0.05). MEDIC and VIBE sequences showed the best contrast ratio between cartilage-meniscus (0.40 ± 0.14, p=0.000) and cartilage-bone (0.75 ± 0.4, p=0.022), respectively. TRUEFISP sequence showed the highest SNR (28.04 ± 14.05, p=0.000) whereas DESS sequence showed the lowest SNR (11.62 ± 3.99, p=0.000). VIBE sequence provided the highest cartilage thickness measurement compared to the remaining 3D sequences (2.0 ± 0.4 cm, IRR=75.33%, ICC=0.96). The quantification of magnetic susceptibility and flow artifacts revealed that TRUEFISP (IRR=59%, ICC=0.92) and SPACE (IRR=59%, ICC=0.96) sequences presented the highest artifacts compared to the others sequences. Conclusion: 3D high-resolution sequences provide knee articular cartilage imaging with high image quality in relatively short acquisition time. MEDIC and VIBE sequences showed the best contrast and the lowest magnetic susceptibility and flow artifacts, TRUEFISP and SPACE sequence showed the highest SNR but they are more sensitive to artifacts, DESS sequence showed medium contrast and VIBE sequence provided the highest cartilage thickness.

“…However, there were several limitations in this analysis 1 : differences in the inclusion criteria and exclusion criteria for patients 2 ; different patients with previous disease and treatments were unavailable 3 ; all the included studies were from English articles, which may be the source of bias 4 ; the fluency of technicians between different studies varied 5 ; difference in the MRI FS 6 ; pooled data were used for analysis; and individual patients' data was unavailable, which limited us to perform more comprehensive analysis. However, there was no significant publication bias of the included studies.…”

This study aimed to evaluate the overall diagnostic value of magnetic resonance imaging (MRI) in patients with suspected meniscal tears. PubMed, Cochrane, Embase database updated to November 2017 were searched by the index words to identify qualified studies, including prospective cohort studies and cross-sectional studies. Literature was also identified by tracking using reference lists. Heterogeneity of the included studies was reviewed to select proper effects model for pooled weighted sensitivity, specificity, and diagnostic odds ratio (DOR). Summary receiver operating characteristic (SROC) analyses were performed for meniscal tears. A total of 17 studies were involved in this meta-analysis to explore the diagnostic accuracy of MRI for meniscal tears. The global sensitivity and specificity of MRI of meniscal tears were 92.0% (95% confidence interval [CI]: 88.0–95.0%) and 90.0% (95% CI: 85.0–95.0%) in medial meniscal tears, and 80.0% (95% CI: 66.0–89.0%) and 95.0% (95% CI: 91.0–97.0%) in lateral meniscal tears, respectively. Moreover, the global positive and negative likelihood ratio of MRI of meniscal tears were 10.33 (95% CI: 6.04–17.67) and 0.09 (95% CI: 0.05–0.14) in medial meniscal tears; 16.48 (95% CI: 8.81–30.83) and 0.21 (95% CI: 0.12–0.37) in lateral meniscal tears, respectively. The global DOR was 81.69 (95% CI: 37.94–175.91) in medial meniscal tears and 56.59 (95% CI: 22.51–142.28) in lateral meniscal tears. The results of area under the SROC indicated high accuracy in medial meniscal tears (area under the curve [AUC] = 0.97, 95% CI: 0.95–0.98) and lateral meniscal tears (AUC = 0.96, 95% CI: 0.94–0.97). This review presents a systematic review and meta-analysis to evaluate the diagnostic accuracy of MRI of meniscal tears. Moderate-to-strong evidence suggests that MRI appears to be associated with higher diagnostic accuracy for detecting medial and lateral meniscal tears.

“…While 3D TSE MRI has been shown to be sufficiently accurate for the detection of internal knee derangement, 21,24,35,36 the efficient acquisition of highquality 3D TSE data has been challenging. Reported 3D TSE techniques describe a spectrum of balancing between acquisition speed and image quality with attempts to decrease acquisition time through the use of large isotropic and anisotropic voxel sizes, long echo trains, onedimensional parallel imaging factors in excess of 2, and partial Fourier undersampling, [19][20][21]24,37,38 which may introduce blurring and aliasing artifacts to various degrees. The spectrum of strategies for the acquisition of 3D TSE pulse sequences ranged from acquisition times of 10-11 minutes with (0.5 mm) 3 isovoxel size and short echo trains 4,24,35 to acquisition times of 5-6 minutes with large isovoxel size (0.9 mm) 3 , anisotropic voxel size (0.5-0.6 mm) 3 , echo trains of up to 121, 3-fold unidirectional parallel imaging acceleration, and partial Fourier undersampling.…”

3T MRI of the knee with optimised isotropic 3D sequences: Accurate delineation of intra-articular pathology without prolonged acquisition times

Abstract: • Cartilage is better visualised with 3D TrueFISP than 3D SPACE sequences. • 3D TrueFISP is a reliable sequence for detecting low- and high-grade cartilage defects. • 3D TrueFISP at 3T provides excellent contrast between cartilage and joint fluid.
