Diagnostic imaging is the evaluation of the body using imaging studies (x-rays, CT scans, ultrasound scans, or MRI) to identify signs of disease and aid in diagnosis.
Imaging diagnosis is based on studies that allow the body’s interior to be observed to look for signs of disease. Imaging studies are part of the tools the doctor has to evaluate his patients, diagnose conditions and determine their severity. They often also help plan treatment and monitor results.
Imaging studies are very varied and use a different technology:
Ionising radiation: X-rays such as conventional x-rays, computed tomography (CT), and mammography, or gamma rays such as scintigraphy
Sound waves: like ultrasound
Imaging tests are done on an outpatient basis, meaning once they’re done, you leave and can continue with your normal activities. Most imaging tests are painless, safe, and noninvasive (no injections or other instrumentation is used).
CT and MRI require lying down without moving for several minutes, which can be uncomfortable for some people. If the doctor requests it, a substance called a contrast agent or dye can be injected, which helps to highlight or highlight an organ or structure that you want to examine.
Imaging studies are also used to guide biopsy sampling; for example, ultrasound-guided breast biopsy or 3D tomosynthesis-guided breast puncture.
Who does diagnostic imaging?
Diagnostic imaging is a medical speciality. The medical specialist in diagnostic imaging is a university professional who has completed the specialisation and has been preparing to interpret images of the body’s interior for several years. The diagnostic imaging specialist prepares the reports of the studies and is available to talk with the doctor in charge when you request it.
There are also diagnostic imaging technicians. These professionals are not doctors but have completed an intensive career that trains them in obtaining medical images. Their work contributes to optimising the quality of diagnostic imaging services, which have evolved and are more complex.
Initially, only plain or contrast-enhanced radiography was available. Technological advances have allowed the development of increasingly sophisticated methods to obtain more detailed and precise images of structures that are difficult to access; for example, CT and MRI provide millimetre brain images.
An example of this is 3D tomosynthesis, which allows the reconstruction of a three-dimensional image of the breast. While the evolution of imaging methods continues, the quality of professionals prioritises diagnostic imaging.
What is diagnostic analysis?
- There are ways to identify the strengths and weaknesses of a company, as well as the opportunities and threats in the foreign market; one of them is through a diagnostic analysis.
- This analysis allows business managers to make the necessary changes for economic profitability.
What are the benefits of diagnostic analysis?
Diagnostic analytics help you get value from your data by asking the right questions and digging deeper to find the answers. And this requires dashboard software that allows you to perform versatile, agile and customisable analysis. So you can get specific solutions for your company.
Examples of diagnostic analysis
If you want to know what’s going on in your business, here are some steps you can use to perform diagnostic analysis on your internal data:
First, prepare your data research, including the questions you will answer. This could be an investigation into the reason behind a problem, such as a decrease in click-through rate or a positive change, a dramatic increase in sales during a particular period or season.
Once you’ve identified the problem, you can run your scan. For example, you might find a single cause, or you might need to analyse multiple data sets to isolate a pattern and find a correlation. Remember that the more time you give your data model to collect, the more accurate your results will be.
Filter your results to include only the most critical factor, or two possible factors, in your report.
Finally, draw your conclusions and make clear arguments using your discovered relationships.
Let’s look at the example of a Human Resources department that wants to measure the performance of its employees based on quarterly productivity levels, absenteeism, and weekly overtime. You could set up your data models, use Python or R for deeper exploration and look for correlations in your data. For example, you could create a Human Resources dashboard for a personalised and real-time analysis of time and visualise the most critical metrics for your organisation.
In short, diagnostic analytics is one of the ways we uncover insights from our data and make it count. There are endless ways to ask data questions, so focus on the questions most critical to your organisation.
The goal of any analytics program should be to gain more relevant information that will lead to more valuable decisions and a better understanding of your business landscape.
