Conventional US and contrast-enhanced US (CEUS) were performed using an Aloka Prosound α10, Toshiba Aplio500, and GE LOGIQ E9. A 3.5–5.5 MHz convex probe was initially used for routine grey-scale and color Doppler scans of the liver, perihilar, abdominal cavity, and thoracoabdominal wall lesions, followed by a 7.0–10.0 MHz linear probe to accurately study the sonographic features of the thoracoabdominal wall masses. The relationship between the lesion site and the surgical scar (surgical incision or percutaneous puncture site) was observed and recorded. For CEUS, an appropriate probe was selected according to the size and depth of the lesion. CEUS examinations were performed using a convex probe with a low mechanical index (MI: 0.07–0.08) and a high-frequency linear array probe with a low mechanical index (MI: 0.12). A bolus injection (2.4–4.8 mL) of the contrast medium (Sonovue; Bracco Company, Italy) was administered via the antecubital vein, followed by a 5 mL saline flush. Contrast enhancement was continuously observed for at least 3 min after injection of the contrast agent. The images were then stored. The contrast enhancement was categorized in the early phase (<30 s after injection) and the late phase (30–180 s after injection).

Two kinds of US systems were used: Toshiba Aplio 500 and GE LogiQ 9. The central frequency of the broadband convex array probe was 3.5 MHz and the mechanical index (MI) ranged from 0.08 to 0.12. The second-generation blood pool contrast agent, SonoVue (Bracco, Milan, Italy), consisting of phospholipid-stabilized shell microbubbles filled with sulfur hexafluoride gas, was used. In each case, a 2.4 ml bolus injection of SonoVue was administered via the antecubital vein, immediately followed by a 5 ml bolus of saline solution. If the CEUS result was unsatisfactory, the procedure was repeated with a time interval of 10 min. The images were stored in DICOM files.

All patients had laryngeal US done then, followed on the same day by flexible laryngoscopy. The laryngeal US was done using the Toshiba Aplio 500 and General Electric Logic P6 and with a linear probe of (7.5–12 MHz frequency).
Patient preparation No preparation is required. There were no significant risk factors as regards the ultrasound examination in this study (a non-invasive procedure).

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.
