Tibia Bone Geometry Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
80 human tibia bones from healthy adults (38 male, aged from 20 to 70 years; 42 female, aged from 23 to 68 years) were scanned using spiral CT, and three-dimensional images were reconstructed using the surface shaded display (SSD) method. GE Hispeed ZX/i scanning was performed using the configuration shown in Table 1.
Three-dimensional reconstruction of tibia geometry was performed using a GE ADW4.0 Image workstation. Three anatomical indices (i.e., the length of twisting segment on the lateral surface of the tibia, twisting angles on different twisting segments, and the anteversion angle of the lateral surface of the tibia) were measured in the three-dimensional images by the GE ADW4.0 Image workstation. Because there was a different torsion angle on the outer surface of the tibia, in order to understand the torsion angle changes, we divided the twist section into four equal parts, that is, first twisting section, second twisting section, third twisting section, and fourth twisting section. The measured indices were then statistically analyzed using SPSS 12.0 statistical analysis software with T-test, ANOVA test and correlation analysis test. There was no history of trauma, surgery, or skeletal disorders in any of the individuals involved in this study.

Pig CT-scanning and Image Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
All pigs were CT-scanned one week before sacrifice employing the General Electric HiSpeed ZX/I (Fairfield, CN, USA) equipment located at IRTA in Monells (Girona,Spain) as explained in [12] (link) and images were analyzed using software VisualPork [18, 19] developed by the University of Girona and IRTA. See Figure 1A and 1B as an example of employed images. See the extended Methods section (supplemental data) for further description.

Abdominal Muscle Contrast Spread Evaluation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Thirty minutes after the last TAP injection, each cadaver underwent a full body CT examination in dorsal recumbency to observe contrast distribution. Scans were obtained using a 16-slice multidetector CT scanner (Hi-speed ZXi; General Electric, Milwaukee, WI, USA). The CT images were obtained in a helical mode at 100 kVp, 300 mA, slice thickness 0.625 mm, and reconstructed using low-pass and high-pass filter algorithms. A board-certified radiologist (C.F.) who was blinded to the treatments provided image interpretation using the Horos™ software (Horosproject.org, Nimble Co LLC d/b/a Purview in Annapolis, MD, USA). The following CT features were recorded: total length (mm) of the contrast spread within the TAP in all directions (cranial-to-caudal, dorsal-to-ventral, and medial-to-lateral), and any intra-abdominal contrast migration (yes/no). The predominant distribution patterns throughout the abdominal musculature for TAP-L and TAP-SL approaches were also described.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
