![]() While plain radiography and MR-arthrography (MRA) remain the gold standard in preoperative assessment, other imaging modalities including biochemical sequences of magnetic resonance imaging such as dGEMRIC as well as computed tomography (CT) and preoperative computer assisted animation and treatment simulation play an increasingly important role when evaluating pathologies associated with FAI. Over the past years, an increasing number of imaging modalities for the evaluation of FAI have made their way into clinical practice. Although the diagnosis is primarily made clinically, imaging plays a crucial role in the preoperative assessment. Selecting the right patient for surgical treatment is imperative. The understanding of the patho-biomechanics has evolved over the past decades leading to a variety of surgical treatment options including open and arthroscopic procedures with promising reported results. Since the description of femoroacetabular impingement (FAI), there has been increasing recognition and interest in this condition. This article provides a summary of current concepts of imaging in FAI and a review of the literature on recent advances, and their application to clinical practice. Advantages of CT include superior bone to soft tissue contrast, making CT applicable for image-guiding software tools that allow evaluation of the underlying dynamic mechanisms causing FAI. Computed tomography may serve as an adjunct. Recent advances in MRI technology include biochemically sensitive sequences bearing the potential to detect degenerative changes of the hip joint at an early stage prior to their appearance on conventional imaging modalities. Routine diagnostic work-up consists of a set of plain radiographs, magnetic resonance imaging (MRI) and MR-arthrography. While the diagnosis of FAI is primarily made based on the patients’ history and clinical examination, imaging of FAI is indispensable. ![]() Following the recognition of femoroacetabular impingement (FAI) as a clinical entity, diagnostic tools have continuously evolved.
