What Is Radiology? Understanding DR, CT, and MRI in Medical Imaging

Radiology is a medical imaging specialty that uses techniques such as X-ray, Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) to non-invasively examine the internal structure and function of the human body. These diagnostic methods are widely used in modern healthcare to aid in the early detection, diagnosis, and management of diseases.

1. Digital Radiography (X-Ray / DR)

At Guangzhou INNORKOM Medical Limited, we specialize in providing state-of-the-art Digital Radiography (DR) systems that deliver fast, clear, and reliable imaging results.

Advantages of DR: Rapid image acquisition, Low radiation exposure, Simple operation with low maintenance costs, Cost-effective for both patients and healthcare providers

Common Applications:

Chest imaging (e.g., lung infections, tuberculosis screening)

Bone fractures and limb evaluations

Basic digestive tract imaging (esophagus, stomach, intestines)

Radiation Dose:

A standard chest X-ray exposes the patient to approximately 0.02 mSv, which is roughly equivalent to the natural radiation received during 20 hours of air travel. For comparison, an average person receives 2.0–3.0 mSv of natural background radiation annually.

⚠️ Note: X-ray exams should be avoided during pregnancy unless absolutely necessary.

2. Computed Tomography (CT)

CT scans provide more detailed and cross-sectional views of internal organs and tissues, making them essential for accurate diagnosis.

Advantages of CT: Non-invasive and fast, High-resolution cross-sectional imaging, Excellent detection of subtle density changes, Enhanced scans improve lesion detection and diagnosis

Common Applications:

Head trauma and brain imaging

Chest and abdominal assessments

Spine, cardiovascular, and vascular disease evaluation

Supplementary scans for unclear X-ray results

Radiation Dose:

Typically 2–5 mSv

Low-dose CT for lung cancer screening has about 10 times the dose of a single chest X-ray and is considered very safe for routine use in high-risk individuals

⚠️ Note: Pregnant women should avoid CT scans unless absolutely necessary.

3. Magnetic Resonance Imaging (MRI)

MRI is a powerful imaging method that uses magnetic fields and radio waves instead of ionizing radiation, making it extremely safe for repeated use.

Advantages of MRI: Superior soft tissue contrast (e.g., brain, nerves), Imaging in any orientation, Completely radiation-free, Functional and molecular-level imaging, No bone artifact interference, No contrast agent required for many vascular images, 3D anatomical localization of lesions

Common Applications:

Brain and spinal cord assessments

Abdominal organs and pelvic examinations

Muscles, ligaments, joints, and vascular evaluations

Radiation Dose:

None (MRI uses no ionizing radiation)

⚠️ Note: MRI may not be suitable for patients with metal implants, pacemakers, or those with unstable health conditions. It is also advised to avoid MRI within the first trimester of pregnancy. Patients with fever may experience discomfort due to heat generation in the magnetic field.
