Ge brightspeed 16 slice ct scanner

Manufactured by GE Healthcare

Sourced in United States

The GE Brightspeed 16-Slice CT Scanner is a computed tomography (CT) imaging system that uses X-rays to produce cross-sectional images of the body. It is capable of capturing 16 slices of the patient's anatomy simultaneously, allowing for efficient data acquisition and faster imaging.

Scans were obtained while patients were in supine position at the end of inspiration, using GE Brightspeed 16-Slice CT Scanner (GE Healthcare, Chicago, Illinois, United States). A radiologist with 10 years of experience evaluated the CT findings i.e. the presence and patterns of infiltrations as ground glass opacities, pulmonary consolidation, and crazy paving.¹⁵ (link) The anatomic distribution of the infiltrations was coded for the right upper, middle and lower lobes, and left upper and lower lobes. A semi-quantitative CT severity scoring system ¹⁶ (link) which was firstly defined to correlate radiological and pathological findings for primary pulmonary fibrosis was applied for each lobe. This method has been widely used for quantifying radiological findings in various diseases including COVID-19.¹³ (link)
^,¹⁴ (link) An important study ¹⁴ (link) has shown that CT scoring >11 was found to be associated with COVID-19 disease severity. The extent of anatomic involvement was coded as 0 (absent), 1 (<5%), 2 (5-25%), 3 (26-50%), 4 (51-75%), and 5 (>75%). The total CT score was computed as the sum of each lobe's scores between 0 to 25. CT findings were also given as follows: normal vs. pathological, maximum chest CT scores >11 vs. ≤11,¹⁴ (link) multilobar vs. unilobar involvement, and unilateral vs. bilateral involvement.

CT Assessment of COVID-19 Lung Involvement

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

All initial chest CT scans were performed on the day of patient admission using a GE BrightSpeed 16 Slice CT Scanner (GE Healthcare). Visual assessment of CT scans was performed by several different experienced radiologists. Radiologists were blind to the clinical signs and symptoms presented by patients at the time of CT scan assessment.
Computed tomography scanning guidelines included the degree of total parenchymal lung involvement and the presence of CT features such as ground-glass opacification (GGO), consolidations, and pleural effusion.
CT images were classified, using a simple score, according to the percentage of the entire lung parenchyma affected by COVID-19 lesions into two groups: non-severe pulmonary damage (<50%) and severe pulmonary damage (≥50%).

CT examinations were performed with a GE BrightSpeed 16 slice CT scanner (GE Healthcare). Slice thickness was between 1.25 mm and 5 mm. Mean tube current was 440 mA, and the mean peak kilovoltage was 340 (SD 40) kVp. Contrast agent was administered with injection rates ranging from 2.5 to 3 mL/s, using Omnipaque or iomeron (both 300 mg iodine per mL).

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.
