Why This Section Matters:

Medical errors can occur when reports get mixed up between patients. Always verify this information matches your records exactly.

What to Check:

  • Your name is spelled correctly
  • Date of birth matches your records
  • Medical record number is consistent
  • Date and time of scan are accurate
⚠️ Red Flag: If any information is incorrect, contact the imaging center immediately before discussing results with your doctor.
📋

Clinical History

Provides the medical context that guides the radiologist's focus during interpretation.

Common Examples:
• "Abdominal pain, rule out appendicitis"
• "Chest pain, evaluate for PE"
• "Follow-up known lung nodule"
Learn More →

How Radiologists Use This:

The clinical history tells the radiologist what to look for specifically. If you have chest pain, they'll pay extra attention to your heart, lungs, and blood vessels.

Verification Tip:

This section should match the reason your doctor gave you for getting the scan. If it doesn't match your symptoms, mention this discrepancy to your doctor.

⚙️

Technique

Technical details about how your scan was performed, including contrast use and scan parameters.

Typical Content:
"Helical CT of abdomen/pelvis with oral and IV contrast. Slice thickness: 5mm"
Learn More →

Key Technical Elements:

  • Contrast material: Helps highlight blood vessels and organs
  • Slice thickness: Determines image detail level
  • Body area: Specific region scanned

Why It Matters:

This information helps doctors compare your scan with future ones and understand any limitations in what can be seen.

📊

Comparison

Compares your current scan to previous imaging to track changes over time.

Examples:
• "Prior CT abdomen from January 2024"
• "No prior studies for comparison"
Learn More →

Value of Comparison:

A small finding that's been unchanged for years is usually less concerning than something new. This section helps determine if findings are stable, improving, or worsening.

If No Prior Studies:

Don't worry if this is your first scan. Radiologists are trained to recognize abnormalities even without comparison images.

🔍

Findings

Comprehensive description of everything the radiologist observed, going organ by organ through your body.

Sample Findings:
"Liver: Normal size and attenuation.
Lungs: Clear bilateral lung fields.
Heart: Normal cardiac silhouette."

Reading Strategy:

Don't get overwhelmed! This section contains the most detail but can cause unnecessary anxiety. Focus on the Impression section instead.

What's Included:

  • Normal anatomical structures
  • Any abnormalities or variations
  • Precise measurements when relevant
  • Detailed organ descriptions
💡 Pro Tip: Radiologists document everything they see, including normal variations that don't require treatment. Many "findings" are actually normal!

Impression (Most Important)

The radiologist's expert conclusion and bottom-line interpretation. This is your roadmap to understanding what matters most.

Example Impressions:
• "No evidence of appendicitis"
• "Stable small hepatic cyst"
• "No acute abnormalities identified"
Learn More →

How to Read the Impression:

✅ Reassuring Phrases:
• "No acute findings"
• "Normal study"
• "No evidence of..."
• "Within normal limits"
⚠️ Needs Follow-up:
• "Recommend follow-up"
• "Clinical correlation suggested"
• "Further evaluation recommended"
🚨 Urgent Attention:
• "Suspicious for..."
• "Concerning finding"
• "Urgent follow-up recommended"
💡

Recommendations

Suggested next steps based on your scan results. Your doctor will determine which recommendations to follow.

Common Recommendations:
• "Clinical correlation suggested"
• "Follow-up CT in 6 months"
• "Recommend gastroenterology consultation"
Learn More →

Types of Recommendations:

  • No follow-up needed: Usually indicates good news
  • Routine follow-up: Monitor in 6-12 months
  • Short-term follow-up: Recheck in 3-6 months
  • Specialist referral: See a specific type of doctor
  • Additional imaging: Different type of scan needed
  • Laboratory tests: Blood work or other tests

Important Note:

Not all reports include recommendations. Your doctor will always determine the appropriate next steps based on your complete clinical picture, not just the scan results.

How to Read Your Report

Follow this proven step-by-step approach to understand the most important information first

1

Start with the Impression

This is your roadmap to the most important findings. It's like the executive summary that answers your key questions: "What did they find?" and "Should I be worried?"

2

Check the Recommendations

See what the radiologist suggests as next steps. This helps you understand what happens next in your care and what your doctor might recommend.

3

Verify Clinical History

Make sure the reason for your scan matches why your doctor ordered it. This provides important context for understanding the results.

4

Reference the Findings (If Curious)

Read the detailed findings only if you want more information. Don't let technical language overwhelm you - the Impression contains what really matters.

⚠️ Most Important Tip

If the impression says "no acute findings" and there are no urgent recommendations, that's generally reassuring news. Don't get overwhelmed by technical details in the findings section.
