Core injuries and athletic pubalgia represent a complex spectrum of musculoskeletal disorders frequently encountered in athletes, particularly those involved in sports that require rapid changes in direction, twisting motions, or high-intensity running. Accurate diagnosis of these conditions is crucial for effective management and rehabilitation, as they often present with nonspecific clinical symptoms that overlap with other hip and groin pathologies. Radiologic imaging, particularly advanced modalities such as magnetic resonance imaging (MRI) and ultrasound, plays an integral role in the assessment and differentiation of core injuries and athletic pubalgia, providing valuable insight into soft tissue damage, bony abnormalities, and the involvement of adjacent structures. This chapter explores the radiological approaches to diagnosing these conditions, emphasizing the utility of imaging in guiding clinical decision-making and optimizing patient outcomes.
