Two experts (EN, OO-V), with 27 and 5 years of experience in musculoskeletal ultrasonography, respectively, performed the scanning of the inferior belly of omohyoid with a conventional 2D B-mode real-time scanner (LOGIQ E10, GE Medical Systems Ultrasound and Primary Care Diagnostics, LLC, Wauwatosa, WI, USA) equipped with a multifrequency linear transducer (ML 6–15 MHz). B-mode settings were standardized for the study: B-mode frequency 15 MHz; B-mode gain 50 dB; and dynamic range 63 dB. To identify the inferior belly of omohyoid, with the subjects seated, the transducer was placed transversely and longitudinally 2–3 cm cranial and posterior to the medial end of the clavicle and moved along a downward and posterior slope toward the trapezius on the dominant side. The depth from the skin surface, the transverse diameter, and the thickness of the inferior belly of omohyoid were measured at the mid-clavicle. Additionally, videos were obtained recording the contraction of the inferior belly of omohyoid during neck flexion. The palpatory and ultrasonographic studies were performed independently of each other, supervised by two senior anatomists (JMG and JRMV).

Percutaneous Radiofrequency Ablation Techniques

All RFA procedures were performed percutaneously under US guidance (LOGIQ E9 or LOGIQ E10, GE Healthcare) by five radiologists with at least three years of experience with RFA using a fusion imaging technique (volume navigation; GE Healthcare) [13 (link)]. The operators used various RFA systems (VIVA RFA System, STARmed; Jet-tip RFA System, RF Medical). An active-tip length-adjustable tip (Proteus RF Electrode; STARmed) or clustered separable electrodes (Octopus Electrode, STARmed) were used. For ICWT, one (Jet-tip, RF Medical) or two (Twin electrodes, RF Medical) electrodes were used [10 (link)].
The operators used the tumor puncturing or no-touch method based on their preference, tumor location, and tumor shape [4 (link)]. Tumor-puncturing RFA refers to conventional RFA in which the operator places one electrode across the center of the tumor or multiple electrodes at the periphery of the tumor. In no-touch RFA, the operator positions multiple electrodes outside the tumor [12 (link)]. The RF energy is then delivered by switching monopolar, switching bipolar, and/or combined modes [5 (link)8 (link)11 (link)].

Cynomolgus macaques were anesthetized with a 10 mg/kg ketamine chloride intramuscular injection. The rete showed a linear echo dense structure under ultrasound (GE Healthcare, LOGIQ E10). The EGFP lentivirus diluent was loaded into a syringe with a needle (KINDLY GROUP, Shanghai, 0.7 × 80 TWLB, www.kdlchina.cn , accessed on 5 June 2021.)) and then injected into the rete of both testicles under the guidance of an ultrasound system. The needle bevel was punctured into the rete of testicular tissue and EGFP lentivirus vehicles were injected from the epididymis head into the rete [29 (link)].

The carotid artery IMT was measured using ultrasound (LOGIQ E10; GE Healthcare Japan, Tokyo, Japan). IMT was measured on the right and left sides in the areas of the common carotid artery, bulbus, and internal carotid artery using a linear probe (#L2-9-D; GE Healthcare Japan, Tokyo, Japan). The maximum-IMT (Max-IMT) was defined as the maximum difference between the first (intima–lumen) and second (media–adventitia) interfaces on the far wall of either the right or the left carotid artery bulb, internal carotid artery, and common carotid artery [29 (link),30 (link)]. Max-IMT was expressed in mm, and the carotid plaque was included in the analysis [14 (link),29 (link)]. Max-IMT ≥ 1.5 mm was considered to confer a significant risk for future cardiovascular events [31 (link)].

Conventional grayscale and CEUS examinations were performed by one of two hepatologists (K.S and H.T with 15 and 5 years of experience with abdominal US, respectively) using a US system (LOGIQ E10, GE Healthcare) equipped with a 3.5 MHz convex transducer (C1-6-D). The imaging mode for CEUS was the amplitude modulation method with a low mechanical index (MI) of 0.16–0.2 and a dynamic range of 63 dB. The Sonazoid contrast agent was injected as a 0.5 mL bolus into an antecubital vein via a 21-gauge peripheral intravenous cannula, followed by a 10 mL saline flush. A timer was started at the time of contrast agent injection. A targeted lesion was recorded continuously as a cine clip for 60 s after injection. During this period, the patient was instructed to breathe gently. After that, the same targeted lesion was recorded at one-minute intervals as a five-second cine clip with breath hold. This occurred between the 2-min mark and the 10-min mark. The sequence that was followed in the CEUS protocol is shown in Figure 1 .

Standardized Muscle Ultrasound Protocol

For the MSUS study, a GE Logiq E10 (Wisconsin, USA, 2019) was used. The grey-scale settings of the machine were kept unchanged for the grey-scale map, gain and dynamic range to ensure a homogeneous assessment of muscle echotexture. Fixed frequencies for superficial and depth structures were used (15 MHz upper extremity, 12 MHz lower extremity).
For all MSUS examinations, generous use of contact gel and minimum pressure with the probe were adopted to avoid muscle compression. Particular attention was given to the correct placement of the probe perpendicular to the area to be examined, in order to avoid changes in muscle echogenicity related to anisotropy.

An ultrasound scan of both hands was performed with a General Electric (GE, Chicago, Illinois, USA) Logiq E10 with a GE ML 6–15 probe. Greyscale pictures were obtained of the metacarpophalangeal (MCP), proximal interphalangeal (PIP), distal interphalangeal (DIP) and first carpometacarpal (CMC) joints in the longitudinal plane from the dorsal side with the joint centered. For each patient, 30 ultrasound pictures (10 MCP, 10 PIP, 8 DIP and 2 CMC) were manually segmented into bone, synovium and osteophytes using the open source software CVAT (17 ). All images and segmentations were then assessed for quality by a rheumatologist, and the pictures were subsequently scored for osteophyte severity from 0 to 3 according to the EOGS (8 ). The rheumatologist assessing for quality has over 10 years’ experience in musculoskeletal ultrasound, has published in the field and is a frequent teacher and organizer of musculoskeletal ultrasound courses.

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.
