Course Overview

Early detection can have a major impact on patient management, treatment options, and outcomes.

Radiologists increasingly play an important role not only in diagnosing symptomatic disease but also in identifying disease during:

• Formal screening programs
• Surveillance examinations
• High-risk patient follow-up
• Incidental imaging review
• Opportunistic screening

The ARRS Early Detection and Screening with Abdominal Imaging 2026 course provides a practical framework for understanding how imaging can contribute to these goals.

Faculty review both established and emerging strategies for screening abdominal diseases and cancers, along with technical considerations and questions surrounding cost-effectiveness.

Why Imaging-Based Screening Matters

Screening imaging differs from diagnostic imaging performed after a patient develops symptoms.

The purpose is often to identify:

• Early-stage malignancy
• Premalignant abnormalities
• High-risk structural changes
• Disease in asymptomatic individuals
• Clinically significant incidental abnormalities

An effective imaging-based screening program requires clinicians to understand:

Disease Risk → Patient Selection → Imaging Technique → Interpretation → Follow-Up → Clinical Management

The course explores these principles across multiple abdominal diseases.

Speakers & Lectures

1. Screening with Imaging: Principles, Technical Aspects, and Cost Effectiveness

Speaker: Lyndon Luk

This introductory session reviews the fundamental concepts behind imaging-based screening.

Topics Include

• Principles of screening
• Imaging as a screening tool
• Patient selection
• Screening populations
• Technical requirements
• Diagnostic performance
• Benefits and limitations
• Cost-effectiveness
• Screening program implementation
• Balancing benefit and resource utilization

The lecture provides the conceptual foundation for understanding the disease-specific screening strategies discussed throughout the remainder of the program.

Principles of Imaging Screening

A successful imaging screening program depends on multiple factors.

These may include:

• Prevalence of disease
• Patient risk
• Sensitivity of the imaging technique
• Specificity
• Availability
• Cost
• Radiation exposure
• Downstream testing
• Incidental findings
• Potential effect on outcomes

The value of a screening method therefore cannot be determined simply by whether an imaging examination can detect disease.

2. Screening for HCC and Cholangiocarcinoma

Speaker: Robert Marks

This lecture focuses on imaging strategies related to major primary hepatic malignancies.

Hepatocellular Carcinoma Screening

Hepatocellular carcinoma (HCC) is an important target for imaging surveillance because many patients develop disease in identifiable high-risk populations.

The session reviews imaging considerations related to:

• HCC screening
• HCC surveillance
• High-risk patients
• Liver imaging
• Early tumor detection
• Surveillance strategies
• Imaging findings
• Follow-up considerations

Early detection can be particularly important because treatment options may differ significantly according to tumor stage and liver function.

Cholangiocarcinoma Screening

The course also examines the role and limitations of imaging in detecting cholangiocarcinoma in patients with relevant clinical risk.

Important considerations include:

• High-risk populations
• Biliary imaging
• Surveillance
• Imaging abnormalities
• Earlier disease recognition
• Limitations of screening

3. Screening for Colorectal Cancer: CT Colonography Updates

Speaker: Kevin J. Chang

This session reviews current developments in CT colonography and its role in colorectal cancer screening.

CT Colonography

CT colonography provides a minimally invasive imaging-based approach for evaluating the colon.

The lecture reviews its role within contemporary colorectal screening.

Important Topics

• Colorectal cancer screening
• CT colonography techniques
• Patient preparation
• Colonic evaluation
• Polyp detection
• Screening indications
• Advantages and limitations
• Current clinical updates
• Incidental extracolonic findings

Colorectal Cancer Screening

Colorectal cancer screening aims to detect:

• Early colorectal malignancy
• Clinically important polyps
• Precancerous lesions

Imaging-based approaches such as CT colonography can form part of broader colorectal cancer screening strategies.

Radiologists should understand both the strengths and limitations of the technique when advising referring clinicians or interpreting screening examinations.

4. Screening for Pancreatic Cancer: Is There a Role for Imaging?

Speaker: Avinash Kambadakone-Ramesh

Pancreatic cancer remains one of the most challenging malignancies for early detection.

This session examines whether imaging-based screening can improve identification of pancreatic cancer at an earlier stage.

Pancreatic Cancer Screening

Pancreatic cancer frequently presents late, making earlier detection an important clinical objective.

The course reviews:

• Current status of pancreatic cancer screening
• Identification of high-risk populations
• Imaging surveillance
• Pancreatic imaging techniques
• Early pancreatic cancer findings
• Precursor lesions
• Limitations of current screening methods
• Potential future directions

Imaging & Early Pancreatic Cancer Detection

Radiologists should be familiar with both obvious and subtle findings that can suggest early pancreatic malignancy.

Assessment may involve:

• Pancreatic morphology
• Ductal abnormalities
• Small masses
• Indirect signs of malignancy
• Cystic lesions
• Interval imaging changes

Understanding subtle imaging findings may allow earlier investigation and diagnosis.

5. Opportunistic Screening with Imaging: Updates

Speaker: Perry J. Pickhardt

One of the most rapidly evolving concepts in radiology is opportunistic screening.

Instead of ordering a separate imaging examination specifically for screening, radiologists may extract additional clinically meaningful information from scans that were already obtained for another indication.

What Is Opportunistic Screening?

Many CT and MRI examinations contain information extending beyond the initial clinical question.

Existing scans may potentially provide data regarding:

• Body composition
• Bone health
• Cardiovascular risk
• Organ abnormalities
• Metabolic risk
• Incidental disease
• Cancer risk

This creates an opportunity to obtain more clinical value from imaging studies without necessarily requiring an additional examination.

Benefits of Opportunistic Imaging

Potential advantages include:

• No additional imaging appointment
• Reduced need for dedicated testing
• Additional disease detection
• Earlier risk identification
• Better utilization of existing imaging data
• Potential population-health applications

The session reviews contemporary opportunities and limitations associated with this evolving field.

6. Screening in Endometriosis: Imaging Updates

Speaker: Myra K. Feldman

The final session examines contemporary imaging approaches related to endometriosis.

Endometriosis can be clinically challenging because disease may involve multiple pelvic and abdominal structures and symptoms can vary substantially between patients.

Imaging in Endometriosis

The lecture reviews current imaging considerations for evaluating suspected or known disease.

Topics may include:

• Detection of endometriosis
• Pelvic imaging
• Disease distribution
• Deep infiltrating endometriosis
• Preoperative assessment
• Imaging characterization
• Disease mapping
• Treatment-planning considerations

Accurate imaging can help clinicians better define the extent and location of disease.

Pancreatic cancer represents one of the most important challenges in abdominal oncology because early disease can be difficult to detect.

The course provides focused education on:

• Imaging-based screening
• High-risk populations
• Surveillance
• Subtle pancreatic abnormalities
• Early malignancy detection
• Limitations of current imaging strategies

This makes the course useful for radiologists who routinely interpret abdominal CT or MRI.

CT Colonography

The colorectal screening lecture offers an update on the role of CT colonography in modern screening strategies.

Radiologists can review:

• Technical principles

Opportunistic Screening

Opportunistic screening is becoming increasingly important as advanced imaging and quantitative analysis allow radiologists to extract more information from routine examinations.

Instead of considering a CT or MRI study as useful only for the original indication, additional imaging biomarkers may potentially contribute to broader disease risk assessment.

This creates opportunities for radiology to become increasingly involved in:

• Preventive medicine
• Population health
• Early disease identification
• Risk stratification
