What Is a Radiologist and What Do They Do?
Radiologists are medical specialists who use medical imaging to help assess and diagnose a wide range of conditions. They interpret images from examinations such as X-rays, CT scans, ultrasound and other forms of diagnostic imaging and provide reports to the healthcare professionals involved in your care.
A radiologist is a medical specialist who interprets diagnostic images and provides imaging reports to help referring healthcare professionals assess a patient's clinical situation. Radiologists may interpret examinations such as X-rays, CT scans, ultrasound and other medical imaging studies. Their role can also involve recommending or participating in image-guided procedures where appropriate.
What Is a Radiologist?
A radiologist is a medical doctor who has specialised training in diagnostic imaging and the interpretation of medical images. Radiologists use their medical knowledge, imaging expertise and the clinical information provided with an examination to assess images and prepare reports.
Medical imaging can provide important information about structures inside the body. However, an image is not usually interpreted in isolation. The reason for the examination, relevant symptoms, medical history, previous imaging and other clinical information may all help the radiologist interpret the study appropriately.
Medical Specialist
Radiologists are medical doctors with specialist training in diagnostic imaging and the interpretation of medical examinations.
Image Interpretation
They assess medical images for relevant findings and consider them alongside the clinical information provided with the examination.
Clinical Reporting
Radiologists prepare reports that communicate relevant imaging findings to the referring healthcare professional.
Image-Guided Care
Some radiologists may also have expertise in image-guided procedures where imaging is used to help guide clinical interventions.
What Does a Radiologist Do?
The role of a radiologist involves much more than simply looking at a scan. They review the available clinical information, assess the images obtained during an examination and communicate relevant findings through an imaging report.
1. Review the Clinical Information
The referral and clinical information help explain why an imaging examination has been requested. This information can provide important context when the radiologist reviews the images.
2. Review the Images
Radiologists examine the images produced during the diagnostic imaging examination. They assess the relevant anatomical structures and look for findings that may help answer the clinical question described in the referral.
3. Compare With Previous Imaging When Available
Previous imaging can sometimes provide useful comparison information. When relevant previous examinations are available, they may help the radiologist assess whether imaging findings have changed over time.
4. Prepare an Imaging Report
After reviewing the examination, the radiologist prepares a report describing the relevant imaging findings. The report is generally provided to the healthcare professional who requested the examination.
5. Communicate Important Findings
Where appropriate, radiologists may communicate significant or urgent imaging findings through established clinical communication processes. The referring healthcare professional can then consider the report alongside the patient's overall clinical situation.
Is a Radiologist the Same as a Radiographer or Sonographer?
No. Radiologists, radiographers and sonographers have different roles within diagnostic imaging, although they work together as part of the imaging process.
| Professional | General Role |
|---|---|
| Radiologist | A medical specialist who interprets diagnostic images and prepares imaging reports. Some radiologists also perform image-guided procedures. |
| Radiographer | Performs examinations such as general X-rays and CT scans, following the appropriate imaging protocols and patient positioning requirements. |
| Sonographer | Performs ultrasound examinations using specialised ultrasound equipment and obtains images and measurements relevant to the examination. |
Roles and responsibilities can vary depending on the examination, workplace and professional qualifications.
Which Types of Imaging Do Radiologists Interpret?
Radiologists may interpret different types of diagnostic imaging depending on their area of practice, training and the services provided by the imaging organisation.
X-Ray
X-rays produce images using ionising radiation and are commonly used to assess bones, joints, the chest and other areas depending on the clinical question.
CT Scan
CT uses X-rays to create detailed cross-sectional images of the body. Radiologists interpret the resulting images in the context of the referral and clinical information.
Ultrasound
Ultrasound uses sound waves to create images of selected body structures. The examination is performed by an appropriately trained sonographer or other qualified professional, with images assessed as part of the reporting process.
DEXA
DEXA or DXA scans measure bone mineral density. The resulting measurements and images can form part of the assessment reported by an appropriately qualified professional.
Why Is the Referral Important to a Radiologist?
The referral provides clinical context for the imaging examination. It can explain the reason for the referral, relevant symptoms, the area of concern and other information that may be important when interpreting the images.
The same body area can sometimes be examined for different clinical reasons. Knowing the clinical question can therefore help guide the imaging and reporting process.
If your symptoms or medical history have changed since your referral was issued, let your healthcare professional or imaging provider know. Relevant clinical information can help the imaging team understand the reason for the examination.
How Does a Radiologist Prepare an Imaging Report?
After the examination is completed, the radiologist reviews the available images together with the clinical information supplied with the referral.
The report generally describes the relevant imaging findings and may provide an interpretation or conclusion appropriate to the examination. The wording and level of detail can vary depending on the type of examination and clinical circumstances.
The imaging report is generally sent to the referring healthcare professional, who can interpret the findings alongside your symptoms, medical history, examination findings and other investigations.
An imaging report is one part of the overall clinical assessment. Your GP, specialist or other referring healthcare professional can explain what the findings mean for you and whether further assessment or follow-up is appropriate.
What Happens After the Radiologist Reviews Your Scan?
Once the images have been reviewed, the radiologist prepares the imaging report according to the examination and clinical information available.
The report is generally provided to the healthcare professional who referred you for imaging. Your referring doctor or specialist can then discuss the findings with you and explain how they relate to your overall health.
Depending on the examination and findings, your healthcare professional may recommend monitoring, additional testing, specialist review or other follow-up. Any recommended next steps depend on your individual clinical circumstances.
Will I Meet the Radiologist During My Imaging Appointment?
Not necessarily. In many diagnostic imaging appointments, the patient interacts primarily with the reception team and the imaging professional performing the examination, such as a radiographer or sonographer.
The radiologist may review the examination and prepare the report after the images have been obtained. Whether you meet or speak directly with a radiologist depends on the type of examination, clinical circumstances and the services provided by the imaging practice.
If you have questions about who will perform or report your examination, you can contact the imaging provider before your appointment.
Does a Radiologist Diagnose Every Medical Condition?
Radiologists contribute to diagnosis by interpreting medical imaging, but an imaging finding is considered alongside the patient's broader clinical information.
Your referring healthcare professional uses the imaging report together with your symptoms, medical history, physical examination and other test results when determining the overall clinical assessment.
This is why the radiology report and the clinical consultation are both important parts of the healthcare process.
Do Radiologists Perform Image-Guided Procedures?
Some radiologists have additional expertise in interventional or image-guided procedures. These procedures use medical imaging to help guide instruments or injections to a specific area of the body when clinically appropriate.
Depending on the procedure, imaging guidance may involve ultrasound, CT or another suitable imaging technique.
CareWell Diagnostix provides selected ultrasound-guided procedures. You can learn more about the service through the Ultrasound-Guided Procedures service page .
Why Is the Radiologist's Role Important?
Diagnostic imaging produces a large amount of visual information. Radiologists apply specialist medical and imaging knowledge to assess these images and communicate relevant findings through a structured report.
Clinical Context
Radiologists consider the clinical information provided with the examination when reviewing the images.
Detailed Image Assessment
Different imaging examinations can contain detailed anatomical information that requires specialist interpretation.
