How Radiologists Read Your Images

Your imaging exam is done. You go home, and within a day or two, your doctor has a detailed report about what was found inside your body. But what happens in between? Here is a behind-the-scenes look at how radiologists read your images.

Who Is a Radiologist?

A radiologist is a medical doctor (MD or DO) who specializes in interpreting medical images. Their training includes:

• 4 years of medical school
• 1 year of internship
• 4 years of radiology residency
• Optional 1 to 2 years of fellowship in a subspecialty (neuroradiology, musculoskeletal, breast imaging, etc.)

At Advanced Medical Imaging, our radiologists are board-certified and have decades of combined experience. This expertise matters because image interpretation is as much an art as it is a science.

The Reading Process

Step 1: Receiving the Images

After your scan, the images are transmitted electronically to a specialized computer system called PACS (Picture Archiving and Communication System). The radiologist views your images on high-resolution medical-grade monitors — far sharper than a standard computer screen.

Step 2: Reviewing Clinical History

Before looking at a single image, the radiologist reviews:

• Why your doctor ordered the exam
• Your symptoms and medical history
• Prior imaging for comparison
• Any specific questions the referring doctor wants answered

This context is crucial. The same finding can mean very different things depending on the clinical situation.

Step 3: Systematic Image Review

Radiologists follow a systematic approach to avoid missing findings. For example, when reading a chest CT, they examine:

• Lungs (every lobe, segment by segment)
• Heart and great vessels
• Lymph nodes
• Bones (ribs, spine, sternum)
• Soft tissues
• Upper abdomen (which is partially visible)

A single CT scan may contain 500 to 2,000 individual images. The radiologist reviews each relevant slice.

Step 4: Identifying Abnormalities

The radiologist looks for anything that deviates from normal:

• Masses or tumors
• Fluid collections
• Fractures
• Organ enlargement
• Blocked blood vessels
• Inflammatory changes
• Incidental findings (unexpected abnormalities)

Step 5: Comparison with Prior Imaging

One of the most valuable parts of image interpretation is comparison. By comparing your current scan to previous ones, the radiologist can determine:

• Whether a finding is new or old
• Whether a tumor has grown, shrunk, or stayed the same
• Whether treatment is working

This is why bringing prior imaging CDs to your appointment is so helpful.

Step 6: Dictating the Report

The radiologist creates a structured report that includes:

• Exam type and technique — What was done and how
• Findings — Detailed description of everything observed
• Impression — A summary with the most important conclusions
• Recommendations — Suggested follow-up tests or actions

Reports are dictated using speech recognition software, reviewed for accuracy, and then sent electronically to your doctor.

How Long Does It Take?

The turnaround time depends on urgency:

• Emergency (STAT) reads — Minutes to 1 hour
• Urgent reads — Within a few hours
• Routine reads — 24 to 48 hours at most facilities

At AMI, results are typically available to your doctor within 24 to 48 hours. We prioritize fast turnaround so you get answers quickly.

Can You See Your Own Images?

Yes. Under federal law, you have the right to access your medical images and reports. At AMI, we can provide:

• A CD of your images
• Access through a patient portal
• A copy of your radiology report

According to the Radiological Society of North America, patients should feel empowered to ask questions about their imaging results and request copies of their reports.

Why Expert Interpretation Matters

Image interpretation requires years of specialized training. Studies published in radiology journals show that subspecialty-trained radiologists have higher accuracy rates than general readers for complex cases. At AMI, our board-certified radiologists bring fellowship-level expertise to every study they read.
