US evaluation of the thyroid gland was performed with an HDI 3000 or HDI 5000 system (Philips Medical Systems, Bothell, WA, USA) or an Acuson Sequoia 512 system (Siemens Medical Solutions, Mountain View, CA, USA). One of three radiologists with 4, 6, and 10 years of experience in thyroid imaging performed a real-time US exam and interpreted the results. US features of diffuse thyroiditis (DT) were defined using the generally accepted standards of diffuse parenchymal hypoechogenicity or a heterogeneous echogenic pattern of the thyroid gland. If focal lesions were accompanied with DT, for example those suggestive of focal thyroiditis or a benign nodule, we conducted fine needle aspiration and included only the lesions confirmed as focal thyroiditis with lymphocytic infiltration.

In vivo USI was carried out on young New Zealand rabbits (provided by animal center of Chinese PLA General Hospital; male or female; 16–20 g of body weight), which were anesthetized with chloral hydrate (10 wt%) first off, and then their hearts were imaged by an ultrasonic imaging machine (Acuson Sequoia 512 system, Siemens) in B mode with 10 MHz ultrasound probe before and after injection with 2 mL of normal saline containing 4.8 mg of PB@(Fe3O4@PEG-PLGA) MCs via ear vein using a syringe.
In vivo MRI was performed on osteosarcoma-bearing nude mice by a 7-T experimental MRI instrument (BioSpec 70/20 USR, Bruker). The nude mice were firstly anesthetized with isoflurane, and T2-weighted images of them were taken before and after injecting 250 μL of normal saline containing 0.6 mg of PB@(Fe3O4@PEG-PLGA) via tail vein. And then, an external magnetic field was applied on the tumor for 20 min, followed by T2-weighted MRI, and the imaging parameters were set as follows: repetition time (TR) = 3000 ms; echo time (TE) = 40.6 ms; field of view (FOV) = 50 mm × 50 mm; slice thickness = 1 mm.
In vivo PAT was done on 6-week-old nude mice using a photoacoustic tomography system (MOST invision 128, iThera) at the scan wavelength of 808 nm, and PAT images of the mice were acquired before and after injection of 250 μL of normal saline containing 0.6 mg of PB@(Fe3O4@PEG-PLGA) MCs via tail vein.

In vitro USI was carried out under flow state to simulate the blood circulation. Firstly, a silicone tube (ID = 3 mm, OD = 6 mm) was set in a tank filled with degassed water with MCs evenly dispersed in. Then the dispersed solution flowed through the tube at a stable speed, and the process was captured by an ultrasonic imaging machine (Acuson Sequoia 512 system, Siemens) in B mode with 10 MHz ultrasound probe. All USI experiments were under the same parameters (Mechanical Index, MI = 0.49) and repeated for three times.
In vitro T2-weighted MRI was acquired using a 7-T experimental MRI instrument (BioSpec 70/20 USR, Bruker). Even dispersions of MCs in normal saline with predetermined concentrations were placed in a series of tubes for T2-weighted MRI, and after careful preparation, the tubes were scanned in a 7-T MRI system.
In vitro PAT was performed with a photoacoustic tomography system (MOST invision 128, iThera). Homogeneous dispersions of MCs in normal saline with desired concentrations were transferred to the containers made of agar, and after being sealed, the containers were scanned in the photoacoustic tomography system.

Ultrasound (US) imaging was performed at the static state in a phantom study in vitro using an Acuson Sequoia 512 system (Siemens Medical Solutions, Malvern, Pa., USA). The phantom was prepared by embedding PCR tubes in agarose gel (3%, w/v). The RVG-GNPs, which suspended in pH 7.4 PBS buffer ([nanoparticle]=1-10 mg/ml), were placed into the phantoms, and then an acid buffer (sodium acetate buffer) was added. The US imaging was monitored using a 15 MHz probe (Acuson model15 L8), and performed in the 2D mode. The RVGPNP with the equal conditions was used to negative control.

Conventional US and CEUS data were acquired with Acuson or Acuson Sequoia 512 system (Siemens Medical Solutions, Mountain View, CA) equipped with a 4C1 convex array probe transducer. The size and echogenicity of the tumor on gray-scale US, were recorded. CEUS was performed with low-mechanicalindex (mainly 0.15–0.19) and dynamic range of 80 dB after the administration of 2.0 ml bolus of SonoVue (Bracco Imaging, Milan, Italy) in the antecubital vein followed by a flush of 5-ml saline. Imaging was continuously recorded on cine clips for 60 s immediately after contrast agent administration followed by intermittent scanning with 10–20 s at each interval for at least 5 min, without any change in the machine settings. The imaging data were divided into arterial (10–30 s), portal (30–120 s), and late phases (>120 s).

To follow muscle perfusion recovery after ischemia, contrast‐enhanced ultrasound imaging (CEU) was performed pre‐operatively and 0, 4, 7, and 11 days post‐operation with a Siemens Acuson Sequoia 512 system equipped with a 15L8 transducer using the Cadence contrast pulse sequencing (CPS) imaging mode with the following parameters: frequency 14 MHz, power −8 dB, mechanical index 0.25, CPS gain 0, and depth 20 mm 66 . Transverse plane perfusion video clips of both ischemic and intact hindlimbs were recorded upon the administration of an intravenous bolus injection of 50 μl of Sonovue contrast agent (Bracco, Milano, Italy) via the jugular vein. Maximal signal intensity (dB) of the video clips, representing relative perfusion, was quantified with Datapro software v2.13 (Noesis, Courtaboeuf, France), and signal intensity–time curves were created (n = 4–10 animals/group).

With reference to the European Mannheim carotid IMT consensus, the intima–media thickness values of the common carotid arteries of the subjects were measured using an Acuson Sequoia 512 system (Siemens Medical Solutions USA, Mountain View, CA). The procedure was performed in subjects in a supine position by an experienced ultra-sonographer who was unaware of the subjects’ demographic and clinical characteristics. Three arterial sites were evaluated: the bilateral distal common carotid arteries, the carotid bulbs, and the proximal internal carotid arteries. Different scanning angles (anterior, lateral, posterior) were used to identify the thickest IMT in each wall. Both left and right carotid IMTs were assessed, and three measurements were performed for each subject. The mean values of the maximum IMT in both left and right sides of the common carotid arteries were defined as carotid artery IMT.

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.
