Imaging encompasses a variety of diagnostic procedures used to capture visual representations of anatomical structures or structures within the body. This can aid:

• Check for health problems; before they show signs,
• Find out what’s causing the current symptoms.
• Keep an eye on diagnosed health issues or how they respond to therapy.

Radiology is a synonym for imaging. Radiologists are medical professionals that focus on diagnostic imaging.

X-rays, CT scans, MRIs, and ultrasounds are a few imaging modalities available today. Different kinds of imaging rely on various methods of image production.

A growing variety of imaging modalities gives doctors more ways to illustrate what’s going on within your body.

Technologists in the medical field who specialize in imaging modalities, such as radiographers for X-rays or sonographers for ultrasound, are known as radiology technicians or imaging technologists.

Is imaging the right choice?

Imaging should be tailored to the patient like any other medical process or treatment. As a result, it is not recommended for regular use when consulting a medical practitioner.

For instance, a thorough medical history and examination are essential for a doctor to arrive at a correct diagnosis of an injury. Although imaging studies can aid in making a diagnosis, they cannot replace a physical examination.

The bottom line is that you should only get an imaging test if it can aid in diagnosis and help you recover faster from your injury or illness.

The various types of imaging procedures that are available:

Magnetic  Resonance Imaging (MRI):

An MRI scan is a type of medical imaging that combines a strong magnetic field, radio waves, and a computer to create high-resolution images of an organ or other internal structure. Several disorders affecting the chest, stomach, and pelvis can be diagnosed using it and can also be used to track treatment progress. Your specialist might ask you to visit an MRI scan center to undergo the procedure.

Why is it performed?

With an MRI, your doctor can inspect your soft tissues, organs, and bones without causing any harm to you. It generates high-resolution images of the body’s interior that aid in the diagnosis of a wide range of conditions.

Computed tomography scan (CT Scan):

To make cross-sectional images (slices) of the bones, blood arteries, and soft tissues inside your body, a computerized tomography (CT) scan combines a sequence of X-ray images collected from different angles around your body and employs computer processing. The images from a CT scan reveal more information than those from a standard X-ray.

Though types of CT scans can be used for a variety of diagnostic purposes, they are especially well suited to quickly examining patients who may have sustained internal injuries in a traumatic event like a car crash. Because of its high resolution, CT scans are widely utilized for a wide range of diagnostic and therapeutic purposes, including injury and illness assessment, surgical planning, and radiation therapy planning. CT scan cost can highly depend on the type of the scan.

Why is a CT scan performed?

Your doctor may recommend a CT scan to aid in the following:

• Muscle and bone problems, like bone cancer and fractures, need to be identified and treated.
• Figure out where a tumour, infection, or clot is located
• Direct medical interventions such as incisions, biopsies, and radiation treatments.
• Diagnose and track problems like cancer, cardiovascular disease, lung nodules, and liver tumours
• Keep an eye on the results of treatments like those for cancer.
• Find hidden punctures and blood loss.

Mammogram: 

X-ray pictures of the breasts are called mammograms for screening purposes. It has other diagnostic applications beyond breast cancer screening, including the exploration of symptoms or out-of-the-ordinary findings on another imaging test.

To get a clear image, mammography requires compressing the breasts between two hard surfaces. Next, black-and-white images captured by an X-ray are seen on a monitor and analyzed for cancerous markers.

Ultrasound:

Sonography, also known as diagnostic medical sonography or diagnostic ultrasonography, employs high-frequency sound waves to create images of internal anatomical structures. Medical professionals can use photos to understand better and treat a wide range of ailments and diseases.

However, some ultrasound exams may require inserting a small device into your body to capture inside organs.

Why is it ultrasound performed?

There are several applications for ultrasound technology

• Examine the reproductive organs and keep an eye on the baby’s development with this helpful tool.
• Diagnose gallbladder disease
• Evaluate blood flow
• Direct a biopsy or tumor-removal needle.
• Examine a breast lump
• Check the thyroid gland
• Find genital and prostate problems
• Assess joint inflammation (synovitis)
• Evaluate metabolic bone disease

Digital radiography:

You may also hear the term “direct digital radiography” when referring to digital imaging. The transition from conventional to digital radiology is similar to the change from film-based cameras requiring darkroom processing to today’s digital cameras.

With filmless digital radiography, images can be acquired, deleted, edited, and transferred instantly to a computer system that generates the image in real-time.

X-rays:

An X-ray is a simple and painless diagnostic tool to obtain images of internal body structures, most commonly bones.

The amount of energy absorbed by your body as an X-ray passes through it varies with the density of the material. White is the predominant colour in X-ray images of dense materials like bone and metal. Your pulmonary air appears dark on the scan. Different grey levels represent muscle and fat.

Difference between CT Scan and MRI:

Images of the scanned region are created by combining a rapid succession of X-ray photos.

Images of the body’s inside are captured by an MRI using powerful magnetic fields.

Whenever possible, CT scans are performed first. Some disorders can only be detected by an MRI and not by a CT scan.

Difference between X-ray and CT scan:

The CT scan is superior to the X-ray because it can catch bones, soft tissues, and blood arteries all at once, while the X-ray is designed to study solid tissues. Since a CT scanner has to rotate around the patient, X-ray equipment can be much smaller and more straightforward.

Medical imaging provides doctors with an accurate depiction of the internal conditions of their patients. Because of this enhanced perspective, you can better assess the severity of your ailment. In addition, doctors using medical imaging can precisely predict the prevalence of diseases like cancer.
