“…Previous studies have reported that there is a significant negative association between MT and EI on quadriceps femoris in healthy older adults 19,29 ) . A previous study of acute stroke patients by Maeda et al reported a significant negative association between MT and EI of the quadriceps femoris 30) .…”

“…EI of individual pixels was expressed as a value between 0 (black) and 255 (white) by 8-bit grayscale, and the mean EI value of each pixel in the region of interest was obtained. Reliability of MT and EI measurements has been established, with intraclass correlation coefficient (ICC) values in the range of 0.90-1.00 for MT and 0.77-0.95 for EI [17][18][19][20][21] . To examine the reliability of our measurements, an ultrasound image of each muscle was obtained on two separate days in eight healthy subjects in another sample of this study.…”

The stroke survivors exhibit change in muscle quantity and quality compared to healthy older adults. This study aimed to compare the muscle thickness (MT) and echo intensity (EI) values of individual muscles between stroke survivors and age-and sex-matched healthy older adults. Methods : In total, 27 stroke survivors and 34 healthy older adults participated in this study. The MT and EI values of the following muscles were assessed from transverse ultrasound images : rectus abdominis (RA) , external oblique, internal oblique, transversus abdominis, rectus femoris, vastus intermedius (VI), vastus lateralis (VL), vastus medialis (VM), tibialis anterior (TA), gastrocnemius (Gas), and soleus (Sol). The MT and EI values of these muscles were compared between stroke survivors and healthy older adults. Results : The MT values of the VL, VM, and RA on the non-paretic sides were significantly higher and those of the TA, Gas, and Sol on the paretic sides were significantly lower in the stroke survivors than in the healthy older adults (P < 0.05). The EI values of the VI, VL, VM, TA on the paretic sides and those of the Gas on both the paretic and non-paretic sides were significantly higher in the stroke survivors than in the healthy older adults (P < 0.05). Conclusion : Stroke survivors seem to develop muscle hypertrophy of the non-paretic thigh muscles owing to a compensatory strategy. In addition, the lower-leg muscles on the paretic side of stroke survivors tend to show both quantitative and qualitative muscle changes.

“…To our knowledge, this is the first study to examine the reliability of EFOV US in the assessment of RA thickness and length. Tanaka et al [27] reported excellent reliability in measuring the RA cross-sectional area (ICC values ranged from 0.944 to 0.958) and echo intensity (0.851 to 0.945) using EFOV US. Further, Keshwani et al [31] examined the inter recti distance (IRD) of RA in postpartum women and found that images acquired using EFOV techniques were highly correlated with those acquired using conventional imaging (r>0.95, p<0.001).…”

“…A limitation of US evaluation is that it permits observation of only a limited region of the muscle of interest and thus, long muscles like the RA, require multiple measurements in different segments. Extended field-of-view (EFOV) US overcomes this limitation as it allows the scanning of entire tissue areas within one continuous scan [26] with high reliability [27]. For the RA muscle, EFOV US can assist in visualizing the distance between tendinous inscriptions, thus proving an estimate of the amount of RA shortening from rest to contraction.…”

Aim: The purpose of the present study was to establish which type of exercise is optimal for Rectus Abdominis (RA) muscle, by measuring thickness and length changes using the extended field of view ultrasonography (EFOV US) during different conditions. The second purpose was to estimate the reliability of EFOV US as a muscle morphology assessment tool.Material and methods: Segmental muscle thickness and length of 11 young healthy adults was assessed during 1) rest and isometric 2) trunk lifting, 3) leg lifting and 4) combined trunk and leg lifting exercises with the use of EFOV US.Results: RA muscle thickness was significantly greater during exercises compared to rest (p<0.05). It was also observed that proximal and proximal-middle segments showed significantly less thickness and length compared to distal-middle and distal segments (p<0.05). Even though no differences in thickness were observed between the exercises, leg lifting and combined trunk and leg lifting exercises affected more the distal segment of RA muscle (p<0.05). Moreover, no significant differences in length between exercises was found (p>0.05). Further, EFOV US displayed excellent reliability as the ICC values ranged from 0.82 to 0.97.Conclusions: According to our observations it seems that exercises that induce lifting of the legs might be more effective for the distal parts of RA muscle. EFOV appears to be a reliable diagnostic tool for measuring RA muscle thickness during rest and contracting states.

“…The stitching is often limited by the lack of clarity of the original image and the lack of accuracy of image matching, resulting in poor results. [11], [12]. So we propose Dual-enhanced EFOV-US method which can reduce noise interference and enhance the resolution of the image, thus improving the quality of the ultrasound wide-range image.…”

Dual-Enhanced Registration for Field of View Ultrasound Sonography

Extended Field of View Ultrasound Sonography (EFOV-US) uses the existing ultrasound images for image stitching, so as to display the shape and scope of organ occupation and the relationship with surrounding tissues comprehensively. However, there are still some problems in Extended Field of View Ultrasound Sonography, such as matching error and unstable quality of image stitching. In view of these problems, we propose Dual-enhanced EFOV-US method that overcomes the limitation and produces higher quality results. Firstly, the gray enhancement method is used to improve the image contrast and reduce the noise interference. Then the super-resolution method based on the generative adversarial network is used to improve the resolution of the ultrasonic image further and increase the number of feature point matching between stitching images. The high quality ultrasound wide-range image is gotten by stitching and fusing the double enhanced image. The experimental results show that the proposed method is effective and practical.
