    Abstract Diabetic foot and ankle complications contribute to substantial mortality and morbidity. Early detection and treatment can lead to better patient outcomes. The primary diagnostic challenge for radiologists is distinguishing Charcot's neuroarthropathy from osteomyelitis. Magnetic resonance imaging (MRI) is the preferred imaging modality for assessing diabetic bone marrow alterations and for identifying diabetic foot complications. Several recent technical advances in MRI, such as the Dixon technique, diffusion-weighted imaging, and dynamic contrast-enhanced imaging, have led to improved image quality and increased capability to add more functional and quantitative information.We discuss the bone marrow abnormalities encountered in daily radiologic assessment: osteopenia, reactive bone marrow edema-like signal, insufficiency fractures, Charcot's neuroarthropathy, osteomyelitis, serous marrow atrophy, digital ischemia, and bone infarcts, along with their pathophysiology and the conventional and advanced imaging techniques used for a comprehensive marrow evaluation.

    Abstract This special report provides a viewpoint on attaining knowledge of essential traits also known as quotients (Q) that can improve the mental, physical, and spiritual satisfaction and health of radiologists. While intelligence Q is generally above-average for most doctors and radiologists, other Qs needed for wholesome personal growth include emotional Q, spiritual Q, cultural Q, and more importantly, the meaning Q. Self-reflection and embracing such elements can aid in personal development, enhanced mental peace, and improved systems-based practice in the context of integrated healthcare organizations. KEY POINT: • Emotional, spiritual, cultural, and meaning quotients can be embraced by radiologists for better self-development and improved systems-based practice in the context of integrated healthcare organizations.

    Abstract The Neuropathy Score Reporting and Data System (NS-RADS) is a newly developed MR imaging-based classification that standardizes reporting and multidisciplinary communication for MR imaging diagnosis and follow-up of peripheral neuropathies. NS-RADS classification has shown to be accurate and reliable across different centers, readers' experience levels, and degrees of peripheral neuropathies, which include nerve injury, entrapment, neoplasm, diffuse neuropathy, post-interventional status, and temporal changes in muscle denervation. This article brings a practical review of NS-RADS classification, representative MR cases, and a step-by-step tutorial on how to approach this staging system. Readers can gain knowledge and apply it in their practice, aiming to standardize the communications between specialties and improve patient management.

    Abstract Being a major load-bearing and dynamic functional joint of the body, the knee joint is prone to injuries to the menisci and ligaments. Injury to one or more of these structures leads to accelerated or premature osteoarthritis and chronic debilitation. The estimated cost of these injuries in terms of diagnosis, treatment, rehabilitation, and person-hours lost amounts to over a billion dollars annually. Understanding the relevant anatomy of knee cruciate and collateral ligaments, their biomechanical functional role, and imaging considerations are essential to assist multi-disciplinary communications and timely patient treatments for improved management. MRI is considered the gold standard over other imaging modalities like X-ray, ultrasound (US), and Computed Tomography (CT) for diagnosing and assessing such injuries. High-resolution 2D and 3D MRI are considerably helpful in planning for knee preservation surgery, and this article reviews the role of such imaging as a valuable aid to knee preservation surgery in pre-and post-operative states. Relevant arthroscopy correlations have been illustrated.

    Abstract With an increasing life expectancy of global human population, there is a growing demand for preservation of native articular meniscus and cartilage to delay joint arthroplasties, especially in younger and active patients. Since damage to the meniscus and hyaline cartilage of the knee have limited intrinsic capacity to heal, such lesions lead to premature and/or accelerated osteoarthritis. However, knee surgical treatments have evolved and may allow restoration of the natural anatomy, delay the progression of damage, and alter the biology of the meniscus and articular cartilage. The knee preservation surgery is aided by timely detection of such injuries and high-resolution illustration and characterization of the pathology using two-dimensional and three-dimensional magnetic resonance imaging (MRI), made possible due to better MR scanner technology and related software improvements. This article reviews the current literature and authors' experience with imaging concepts and high-resolution MR imaging techniques as they relate to management and planning for such restorative procedures. Relevant arthroscopy correlations have been illustrated.

    Abstract Patellar tendon ruptures can be debilitating injuries. When incomplete, partial tears can be managed nonsurgically with immobilization and progressive rehabilitation. Although complete ruptures remain a relatively uncommon injury, they portend a high level of morbidity. Ruptures typically result from an acute mechanical overload to the extensor mechanism, such as with forced quadriceps contraction and knee flexion. However, chronically degenerated tendons are also predisposed to failure from low-energy injuries. Diagnosis can often be made clinically with recognition of a palpable defect to the tendon, localized patellar tendon tenderness, and inability to actively extend the knee. Diagnosis and surgical planning can be established with radiograph, ultrasonography, or magnetic resonance imaging. Surgical repair is the mainstay of treatment, and there have been many recent advances in repair technique, optimal reconstruction strategies, and supplemental fixation. Time to surgery for complete tears remains the most important prognosticator for success. Direct primary repair can be completed with transosseous tunnels, suture anchor repair, or end-to-end repair. Tendon reconstruction can be achieved with or without mechanical or biologic augments. Rehabilitation programs vary in specifics, but return to sport can be expected by 6 months postoperatively.

    Abstract Peripheral neuropathy is a prevalent and debilitating condition affecting millions of individuals globally. Magnetic resonance neurography (MRN) and ultrasonography (US) are noninvasive methods offering comprehensive visualization of peripheral nerves, using anatomical and functional imaging biomarkers to ensure accurate evaluation. For optimized MRN, superior and high-resolution two-dimensional and three-dimensional imaging protocols are essential. The anatomical MRN and US imaging markers include quantitative measures of nerve and fascicular size and signal, and qualitative markers of course and morphology. Among them, quantitative markers of T2-signal intensity ratio are sensitive to nerve edema-like signal changes, and the T1-mapping technique reveals nerve and muscle tissue fatty and fibrous compositional alterations.The functional markers are derived from physiologic properties of nerves, such as diffusion characteristics or blood flow. They include apparent diffusion coefficient from diffusion-weighted imaging and fractional anisotropy and tractography from diffusion tensor imaging to delve into peripheral nerve microstructure and integrity. Peripheral nerve perfusion using dynamic contrast-enhanced magnetic resonance imaging estimates perfusion parameters, offering insights into nerve health and neuropathies involving edema, inflammation, demyelination, and microvascular alterations in conditions like type 2 diabetes, linking nerve conduction pathophysiology to vascular permeability alterations.Imaging biomarkers thus play a pivotal role in the diagnosis, prognosis, and monitoring of nerve pathologies, thereby ensuring comprehensive assessment and elevating patient care. These biomarkers provide valuable insights into nerve structure, function, and pathophysiology, contributing to the accurate diagnosis and management planning for peripheral neuropathy.
