X-ray Attenuation of Au NR@PAMAM-GX1

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

X-ray attenuation property of Au NR@PAMAM-GX1 was performed using a LightSpeed VCT imaging system (GE Medical Systems, Milwaukee, WI, USA) with the parameters of 100 Kv, 80 mA, and a thickness of 0.625 mm. Au NR@PAMAM-GX1 dispersion with series of Au concentration was placed in 0.2 mL Eppendorf tubes for CT imaging. All images were converted to Hounsfield units (HU) through using the built-in software.

Light-Triggered Contrast Agent Imaging

Firstly, the LTCA solution was placed in a quartz cuvette and irradiated by NIR laser for 10 min at 1 W/cm². C6 cells were seeded in 25 cm² flask and allowed to grow to ~80% density. Then, the medium was replaced by 2 mL of fresh medium containing various concentrations of LTCAs (I^-: 2, 4, 6, 8, and 10 μM). After incubation with LTCAs for 4 h, the medium was replaced by 1.5 mL of cell lysis reagent. The cell lysis solution was then collected for CT imaging. CT scans were performed using a GE Light Speed VCT imaging system at 80 kV and 100 mA, with a slice thickness of 0.625 mm. As a control group, the LTCA solution without irradiation was also evaluated as in the aforementioned procedure. In vitro light-triggered MRI imaging was determined by 3.0-T clinical MRI scanner system (Siemens, Berlin, Germany) at T1WI and T1 map sequences with TR 15 ms and TE 2.1 ms. The cell sample was prepared as in the aforementioned CT procedure; the incubated concentrations of Gd(III) were 0.06, 0.12, 0.18, 0.24, and 0.3 mM.

Multimodal Imaging of C6 Tumor-Bearing Mice

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

C6 tumor-bearing BALB/c nude mice were injected with the LTCA solution (200 μL) through the tail vein. After the injection, the tumor CT images of mice with or without laser irradiation were obtained with GE Light Speed VCT imaging system (80 KV, 100 mA, slice thickness 0.625 mm). The in vivo MRI imaging was also evaluated as in the aforementioned procedure and performed on a 3.0 T clinical MRI scanner system (Siemens) at T1WI, T1 map sequences with TR 15 ms and TE 2.1 ms. FI imaging was conducted with a PerkinElmer IVIS system (PerkinElmer, Inc., Santa Clara, USA). Tumor imaging before irradiation was used as control.

ECG-Gated Cardiac CT for Surgical Planning

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

ECG-gated cardiac CT image sets were collected prior to each surgery using a LightSpeed VCT imaging system (GE Medical Systems). Image sets were collected during a breath hold after inspiration (i.e. a halt of the forced respiration system), which corresponds to a ground-truth respiration phase âˆ…_R* = 0.3.
The desired cardiac phase of the image sets was âˆ…_C = 0.7, corresponding to the most common motion-free imaging window during diastole.¹⁷ The cardiac phase for each slice in the image sets, as shown in Figure 4, was estimated using image metadata, which included the time each image was collected as well as the time of every detected QRS complex in the ECG. Cardiac phase for each slice was calculated as the proportion of time between successive QRS detections. While 3 of the image sets do have jumps in cardiac phase, the portion of the cardiac cycle ranging from 0.6â€“0.8 is relatively motion-free.¹⁸ Cardiac phase for the entire image volume, âˆ…_C*, was estimated as the average phase of the image slices, and ranged from 0.61 to 0.67. Image sets had an axial slice thickness of 0.63 mm, with in-plane pixel spacing of 0.49 mm.

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.
