Testicular Volume Evaluation using Ultrasound

Check if the same lab product or an alternative is used in the 5 most similar protocols

A Phillips iU22 US scanner with an L17-5 MHz linear probe was used for the determination of testicular structure and volume. Volume was calculated using the approximation for a prolate ellipsoid: V = 0.523 × length × thickness × width.^{[7 (link)]}The testicular volume ratio was calculated by the equation of the operated testis volume to the scrotal (control) testis mean volume. The scrotal testis mean volume was calculated according to the results of reference group.
The structure of the testis was assessed in gray scale with the same settings of the gain, focus, and depth. Echogenicity was scored in 2 grades, normal (homogeneous) and abnormal (inhomogeneous). Microlithiasis was defined as 5 or more echogenic foci per view in the testis. All US scans were performed by 1 radiologist with 15 years’ experience in the field of clinical US.
SPSS statistical software version 14.0 was used, with Wilcoxon signed ranks test for the analysis of differences between ratios.

US-guided RFA was performed using grey-scale imaging with a iU22 US scanner and a high-frequency linear probe (L12-5) (Philips, The Netherlands), while contrast-enhanced ultrasound (CEUS) with a high-frequency linear probe (L9-3) was used to monitor the RFA procedures (Fig. 2A,D), as well as the initial diagnostic evaluation and the follow-up¹⁵. All patients were studied with US before the treatment by one of two radiologists (Kefei Cui and Yuanjing Huang) enrolled in the study, with 35 and 20 years of thyroid US experience, respectively.Figure 2

RFA procedure of a benign thyroid nodule. (A) Preoperative contrast enhanced ultrasound (CEUS) was used to define the blood perfusion of the nodule and evaluate the benign signs. (B) Ablation was performed layer-by-layer using the moving-shot method: the needle inside the lesion with the appearance of a hyperechogenic area represented the ablated area. (C) Gland was basically ablated. Most of the glandular region is coated with coagulated and necrotic hyperechoic vaporization region. (D) Postoperative contrast enhanced ultrasound (CEUS) was applied to assess the thoroughness of ablation.

Sonographic Evaluation of TIPS Performance

Check if the same lab product or an alternative is used in the 5 most similar protocols

A physician with at least 3 y experience in sonography performed all the sonographic examinations using an iU22 US scanner (Philips Healthcare, Bothell, Washington, USA). In all the patients, we measured the spleen size, the direction and flow velocity of the main portal vein. In the patients with TIPS, we evaluated the direction of flow (hepatopetal vs. hepatofugal) of the main portal vein and intrahepatic portal vein branches (hepatopetal vs. hepatofugal), and we measured the flow velocity in the shunt at two sites (proximal and distal).
The CDUS parameters analyzed and considered as pathologic were: the presence of a hepatofugal direction of flow in the main portal vein, a flow velocity of the main portal vein slower than 30 cm/s, a hepatopetal direction of flow in the intrahepatic portal vein branches and a flow velocity in the TIPS <90 cm/s and/or >190 cm/s.

Multimodal Imaging and Ablation Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

An iU22 US scanner (Philips Medical Systems, Bothell, WA, USA) or a LOGIQ E9 US scanner (GE Healthcare, Milwaukee, WI, USA) was equipped with high-frequency line-array probes (L9-3/L12-5/ML6-15-D) for conventional US imaging and contrast-enhanced US (CEUS). A radiofrequency system (VIVA; STARmed, Goyang, South Korea) was used as the main equipment for ablation procedures.

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.
