Doctors who specialise in imaging are called radiologists. There are many different types of imaging, such as X-rays, CT scan computed tomography scan , MRI magnetic resonance imaging and ultrasound.

Medical Imaging Modalities involving X-rays and Medical Radiation

Each imaging type uses a different technology to create an image. This increasing range of imaging types provides health professionals with many options for showing what is happening inside your body. Radiology technicians or imaging technologists are health professionals who are trained to use specific imaging types, such as radiographers for X-rays or sonographers for ultrasound imaging.

Like any medical procedure or treatment, imaging should be chosen to suit your individual needs. For example, the first and most important step when making an accurate diagnosis of an injury is for your health professional to take your medical history and perform a physical examination.

Each one uses a specific technology. They differ in how well they show what is happening in certain body tissues. For example, X-rays are often best at finding a break of a bone, whereas an MRI may be better for identifying a ligament injury. When your health professional decides what kind of imaging to recommend to you, they take the different strengths of each imaging type into account.

No type of imaging is always better. Each has different potential advantages and disadvantages, including exposure to radiation with some types of imaging. Your health professional should discuss with you which type of imaging is most appropriate for you. Uses multiple X-rays to produce cross-sectional layers that show detailed images inside the body, including bones, organs, tissues, and tumours. Involves injecting, inhaling or swallowing a radioactive 'tracer'. The gamma-rays emitted by this material are used by the scanner to show images of bones and organs.

Uses magnetic fields and radio waves to show detailed images of organs, soft tissues, bones, ligaments and cartilage. Uses high-frequency sound waves to produce moving images onto a screen of the inside of the body, including organs, soft tissues, bones, and an unborn baby.

You need to know your imaging choices, find out the advantages and disadvantages of each type of imaging and talk to your health professional about any questions or concerns you may have. Choosing Wisely Australia.

Choosing Wisely Australia is an initiative that brings the community together to start important conversations among healthcare providers and consumers. These conversations aim to improve the quality of healthcare through reconsidering tests, treatments and procedures where evidence shows they provide no benefit or, in some cases, lead to harm. Facilitated by NPS MedicineWise, it is led by a large cross-section of colleges, societies and associations that have identified practices that warrant scrutiny, and by examining the evidence and drawing on the expert opinion of their members, have developed lists of recommendations.

Moreover, while ultrasound requires a skilled examiner and a constant visual feedback guiding the position of the ultrasound probe, topography of CT scans and MRIs are easier to grasp. The number of patients included per study varied from 6 to Email or Customer ID. However, we believe it is highly unlikely that the limited weighted analyses affected the outcome, since these 15 studies involved patients, i. Webmaster Contact: info benthamscience. Some types of medical imaging work without using ionizing radiation, for example magnetic resonance imaging MRI and ultrasound imaging, and have specific uses in the diagnosis of disease. However, questions arise.
