Radiology reports are essential tools for diagnosing and monitoring medical conditions. However, they’re often filled with complex medical terminology that can leave patients feeling confused and overwhelmed. This blog post aims to demystify some common radiological terms, empowering you to better understand your reports and participate more actively in your healthcare journey.

The Building Blocks:
Radiology reports use a combination of terms related to:
Anatomy: Describing the location of findings (e.g., “left upper lobe of the lung”).
Size and Shape: Characterizing the dimensions and form of abnormalities (e.g., “2 cm nodule,” “irregular mass”).
Density and Intensity: Describing how structures appear on different imaging modalities (e.g., “hypodense lesion on CT,” “hyperintense signal on MRI”).
Location and Relationship: Specifying the position of findings relative to other structures (e.g., “adjacent to the aorta,” “superior to the kidney”).
Comparison: Comparing current findings with previous studies (e.g., “stable size,” “increased enhancement”).
Common Terms Explained:
Let’s break down some frequently used terms by category:
1. Describing Abnormalities:
Lesion: A general term for any abnormal tissue finding.
Nodule: A small, round, solid lesion.
Mass: A larger, less defined lesion, which may be solid or cystic (fluid-filled).
Cyst: A fluid-filled sac.
Infiltrate: Diffuse spreading of abnormal cells or fluid within a tissue.
Effacement: Obliteration or compression of a normal structure.
Opacity: An area that appears denser or whiter on X-ray or CT scan, often indicating a solid or calcified structure.
Lucency: An area that appears darker or less dense on X-ray, often indicating air or fluid.
2. Describing Location and Relationship:
Proximal/Distal: Closer to/further from the center of the body or a point of reference.
Superior/Inferior: Above/below.
Anterior/Posterior: Front/back.
Medial/Lateral: Closer to/further from the midline of the body.
Ipsilateral/Contralateral: On the same side/on the opposite side.
Adjacent: Next to or near.
3. Describing Shape:
Well-defined/Ill-defined: Clearly demarcated borders/poorly defined borders.
Regular/Irregular: Smooth borders/uneven borders.
Circumscribed: Clearly defined and rounded.
4. Terms Related to Imaging Modalities:
CT Scan (Computed Tomography):
* Hyperdense/Hypodense: Appearing brighter/darker on CT scans, indicating denser/less dense tissue.
* Enhancement: Increased brightness after contrast administration, often seen in tumors.
MRI (Magnetic Resonance Imaging):
* Hyperintense/Hypointense: Appearing brighter/darker on MRI images, related to how tissues respond to magnetic fields.
* T1-weighted/T2-weighted: Different MRI sequences that highlight different tissue characteristics.
Ultrasound:
* Anechoic: Appearing black on ultrasound, usually indicating fluid.
* Hypoechoic/Hyperechoic: Appearing darker/brighter on ultrasound, indicating different tissue densities.
5. Other Important Terms:
Benign: Non-cancerous.
Malignant: Cancerous.
Metastasis: Spread of cancer to other parts of the body.
Stable: No significant change compared to previous studies.
Progressive: Showing worsening or growth.
Follow-up: Recommended imaging studies to monitor changes over time.
Tips for Understanding Your Report:
Don’t hesitate to ask: Your doctor is the best resource for explaining your report. Don’t be afraid to ask questions until you understand.
Look up unfamiliar terms: Use online medical dictionaries or reputable websites to look up terms you don’t understand.
Focus on the “Impressions” section: This section summarizes the key findings and the radiologist’s interpretation.
Compare with previous reports: If you have previous reports, compare them to see if there are any changes.
Seek a second opinion: If you have any concerns or questions, consider seeking a second opinion from another radiologist or specialist.
Empowerment Through Understanding:
Understanding your radiology report can be empowering. It allows you to have more informed conversations with your doctor, participate in shared decision-making, and feel more in control of your health. While this guide provides a starting point, remember that it’s not a substitute for professional medical advice. Always consult with your doctor to discuss your specific situation and any questions you may have. If you want to know how to understand PET-CT report, please click here.
