NBCE Part III is where everything becomes real.

Suddenly:

• It’s not about flashcards — it’s about decisions.
• It’s not “what is it?” — it’s “what do you do next?”
• It’s not safety in a classroom — it’s safety for real patients.

And then there’s DXI — where images aren’t labeled, and tiny details change everything.

If you’re feeling nervous, you’re not alone.

Most students say Part III + DXI is the first time they worry:

“What if I can’t think clearly under pressure?”

This guide breaks down:

• Why students struggle here
• What the NBCE actually tests (and how)
• The most high-yield DXI patterns to master
• A performance-driven strategy for passing with confidence

What Part III Really Tests (That School Doesn’t)

While classes test knowledge, boards test competence:

• Pattern recognition
• Safe next-step decision-making
• Clinical confidence
• Elimination under time pressure

You don’t need to know everything.

You need to know what actually changes management.

Why DXI Feels Harder Than It Should

School radiology often focuses on:

• Rare findings
• Detailed memorization
• Technical terminology

Boards focus on:

• 🔥 Red flags
• 🔁 Common conditions
• 🚫 Contraindications to adjusting
• 🧠 Clinical relevance

If a resource doesn’t mirror that shift → your brain freezes.

The Part III Strategy That Improves Scores Fast

1. Learn “Board Imaging Patterns,” Not Every Variant

Boards reuse:

• Location patterns
• Aggressive vs non-aggressive clues
• Joint space change + soft tissue correlation

2. Train a Decision Tree

Every question → ask:

❓ “What’s most dangerous here?”

❓ “What changes care?”

❓ “What requires referral?”

❓ “Is imaging enough or do I need labs?”

Confidence grows when you practice THIS thought process — not memorization.

3. Timed practice matters

Pressure changes performance.

Simulation builds resilience.

DXI: The High-Yield Conditions Boards Test Most

Students get the greatest score jump from these categories:

These appear far more frequently than:

• Rare congenital anomalies
• Esoteric biomechanical variants

High performers study what scores points.

Period.

What Students Who Pass Do Differently

Students who pass Part III + DXI on the first try:

• Practice mixed question styles early (not siloed)
• Build decision-making confidence
• Focus on NBCE-specific patterns
• Learn when NOT to adjust
• Review mistakes without spiraling

Passing isn’t about perfection — it’s about making consistently safe choices.

What Students Say About NBCE Success

“CAL finally made imaging make sense — not scary.”

“I stopped overthinking and started recognizing patterns.”

“Practicing decisions changed everything for my score.”

Frequently Asked Questions (FAQ)

What’s the passing score for Part III?

A scaled score of 375 is required —most students fall short from stress + misprioritization, not lack of knowledge.

Is DXI the hardest part?

Many students say yes, because:

• It requires clinical thinking
• Under a time limit
• With zero clues in the image

But you can train this brain state.

How do I study imaging quickly?

Use:

• Pattern-based categorization
• Clinical urgency hierarchy
• Mixed practice that trains recognition speed

Should I study Part III & DXI together?

Yes — they are built to integrate.

Boards want to see whether you can apply imaging directly to care decisions.

Do I need a board review course for DXI?

If imaging currently feels unclear or stressful → yes

A structured approach prevents panic and delays.
