The world around us is being understood at a deeper and deeper level in so many different ways. As we start to break down particles and molecules at a smaller level, we are getting to grips with the makeup of different objects and how they are composed, as well as what they are made up of. This information tells us so much about the world around us that it would have once been impossible to determine and highly difficult to get to grips with. 

Of course, the ability to better understand objects is highly useful for the general development of human knowledge, but it also means that we are going to be able to better develop things in the manufacturing process, and this can be used in plenty of different fields including healthcare. The ability to understand objects is done through the use of modern tools. More and more of these are being developed all the time. In the following sections, a closer look will be taken at some of these tools and the impact that they had on past, present, and future understanding of objects, exactly what they are composed of, and much, much more.

Microscope 

At the layman’s level, many people think of a microscope as being one that is put on a desk and used in high school science experiments. However, there is no doubt that this only scratches the surface of what is possible, and there are more and more powerful versions of this simple starting point that allow a closer and closer look at the molecules that make up a particular object. Of course, power is something that increases significantly with time, research, and development, all of which have been done to a significant degree with microscopes. 

Particle Size Analyzer 

These are being used to a greater and greater degree in the world of healthcare as they are particularly important in pharmacy and the manufacturing process of new medicines, which is becoming more advanced and developed than ever before.

X-Ray Diffractometers 

These pieces of equipment are highly advanced and being developed by the likes of malvernpanalytical.com. Ultimately, these can be used in a vast array of different environments, including many universities and research facilities. The process of x-raying objects is one that has been around for a long time, but at the same time, it is also something that has become more and more advanced over recent months and years. 

Molecular Machine 

Finally, we have the molecular machines that are commonly used and come in the form of artificial and biological. Both of them have their specific uses and can tell us a lot more about different objects.

These are just a few of the pieces of equipment that allow us to understand objects at a deeper and deeper level. There is no doubt that more will be developed over the coming months and years as we seek to develop an even deeper understanding of the world around us.

Chiropractic and Diagnostic Imaging

Back and neck pains are chiropractic domains(1). Chiropractic (manual therapy) deals with the spine structure’s realignment to address functional impairments, muscle weakness, and pain(2).

Doctors examine the spinal column and base their diagnosis through imaging tests, such as MRI (magnetic resonance imaging), radiography or X-ray, and CT (computed tomography) scan(3).

Chiropractic adjustments can help correct the body’s alignment, relieve pain, and promote healthy body function(4). These adjustments alleviate muscle and joint pains, headache, neck pain, and low back pain(5).

Chiropractors use manual treatment methods and do not prescribe medication for any conditions.

Some of the chiropractic treatments that are used involve sustained pressure on particular joints and stretching in improving joint motion and function(6).

Chiropractors use therapies, stretching, and exercises to relieve spasms, relax tight muscles, improve mobility and range of motion, and release body tensions(7).

These treatment methods are done through the use of gentle but quick hand thrust(8). An assessment that involves diagnostic imaging must be done to verify the spine’s condition before going through these treatments.

Radiography is said to offer superior results compared to other primal treatments(9). X-ray licensure for the ownership and use of the machine has been attained by chiropractors since 1910(10).

However, some people have criticized the exposure in spinal radiography(11).

In the last 30 years, the management and diagnosis of spinal pain changed from a static mechanical model (X-ray) to a patient-centered model that increased the awareness of the risk of X-rays in evaluating spinal pain(12).

Currently, 8% to 84% of patients continue to use X-rays for chiropractic consultations(13).

A study conducted in 2012 reported that chiropractor’s diagnostic imaging use is influenced by several factors, such as social influences, belief about X-ray capabilities, knowledge, and professional role and capabilities(14).

Even so, due to the positive evolution of diagnostic imaging, various trends arise.

The Evolving Trends

• Digital Imaging Tests

        At present, X-ray is not the only imaging modality that can be used for chiropractic evaluations.

Diagnostic imaging assessments are now made easier with digital imaging that allows chiropractors to take images, adjust if needed, and send them to a radiologist for interpretation.

The move from radiographic imaging to digital imaging benefits patients by having quicker diagnosis and treatment plans while putting up with less radiation exposure.

According to a study on the advantages of digital radiography, switching to digital from film radiography may improve diagnosis due to the readily available and more objective data(15).

• Chiropractic Training in Diagnostic Imaging

        Chiropractors need to pass the National Board of Chiropractic Examiners (NBCE) test to ensure that they have the requisite knowledge and skills to perform their functions safely and effectively(16).

Due to the transition from film to digital diagnostic imaging, Part IV of the NBCE exam was revised.

An evaluation study in The Journal of Chiropractic Education in 2020 reported that the transition to digital diagnostic imaging in the chiropractic board exam relied on empirical research, was well thought through, and aligned with the US chiropractic curricula(17).

This study has significant implications for the further development of the additional skill set of chiropractic students and faculty in digital diagnostic imaging.

The extensive training that the chiropractors undergo today includes bone and soft tissue X-ray (radiography), magnetic resonance imaging (MRI), ultrasound, and computed tomography (CT) scan.

Continuous chiropractic training ensures that chiropractors perform updated diagnostic imaging practices.

However, some chiropractors still refer patients to imaging centers to diagnose and plan treatment for their conditions.

• Diagnostic Imaging Options

        Recently, there have been chiropractic imaging recommendations for evaluating the spine aside from plain film radiology.

A study recommended some diagnostic imaging modalities that may be helpful in the practice of chiropractic treatment. These techniques include the following(18):

Full Spine Radiography

        This radiograph type shows the whole spine that has been a vital diagnostic tool until today(19). However, full-spine radiography has garnered several criticisms over the years due to its radiation exposure.

Various developments have made this imaging technique effective and safe. Full-spine radiography is helpful in spinal alignment (scoliosis), postural disorders, and routine screening of chiropractic patients(20).

Magnetic Resonance Imaging (MRI)

        The use of MRI can be an inexpensive, specific, and sensitive method of analyzing changes in bone structure(21). Magnetic fields and radio waves help produce body structure images.

This diagnostic test is used with an intravenous contrast, which gives a clearer picture of the body’s bone structures(22).

Epidural scarring can be differentiated from residual disc material when MRI is performed in postoperative patients.

Computed Tomography (CT) Scan

        The CT scan is often used to evaluate trauma(23). This diagnostic modality can also view the spinal column and distinguish lesions in the intradural and epidural space(24).

Even though these modalities show promise in the future of chiropractic treatment, further research is still needed.
