Simplified matching and tuning experimental receive coils for low-field NMR measurements( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Highlights: The theoretical circuit analysis performed - Fig. 1, Eqs. (1)-(10). The optimization procedure for matching the coil - Eq. (9). The theoretical analysis of matching and tuning performed - Fig. 2. The noise spectral analysis performed - Fig. 3. The arrangement of the coil tuning utilizing the noise - Fig. 4. Results of the experiments - Fig. 5. Abstract: This article describes theoretical and practical results of experiments with home-made receive coils for an NMR scanner. A receive coil must ensure good sensitivity of the whole receiving chain, therefore the qualities of the coil are analysed together with a preamplifier. The coil must be tuned to the operating frequency of the scanner and matched to the input resistance of the preamplifier for effective processing of the induced signal. A technique for calculating matching device parameters using an optimization procedure is presented. The accuracy of the tuning and matching is analysed in the article and documented in figures. A technique for tuning the coils utilizing the spectral qualities of the noise produced by the receive coil or flowing through it is presented. The results are documented in figures for two coils and compared with assumed theoretical curves. The qualitative as well as the quantitative agreement is good. It has been proved that by fulfilling some conditions, accurate matching is not necessary and the noise spectrum can be utilized for tuning a receive coil

The compositional difference between ankle and knee cartilage demonstrated by T2 mapping at 7 Tesla MR( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Highlights: T2 values of knee and ankle cartilage are statistically significantly different. T2 of knee cartilages is higher than that of the ankle. T2 reflects the differences of collagen structure in various cartilages. Abstract: Objectives: The aim was to systematically compare T2 relaxation times of the knee and ankle cartilage within subjects at 7T. Methods: Ten healthy volunteers were examined by 7 Tesla MR using a three-dimensional triple-echo steady state sequence (3D-TESS). The differences between seven cartilage compartments (patella, femur, proximal tibia, and distal tibia and talus in both medial and lateral facet) were analyzed by ANOVA. Results: The results showed statistically significantly higher T2 (mean ± standard deviation, in milliseconds) values in patellar (25.8 ± 1.2) and femoral (24.9 ± 1.3) cartilage compared to the tibial (19.2 ± 1) and talar (18.1 ± 0.6 ms) cartilage. The cartilages of the medial and lateral facet in the ankle joint were not significantly different (p> 0.05). Conclusions: This is the first study to systematically compare within-subject T2 values in the knee and ankle non-invasively, in vivo . Our results are in agreement with the previous findings demonstrating different biochemical and biomechanical properties between the knee and ankle cartilage
