These pitfalls may be secondary to variant anatomy, artifactual due to magnetic resonance imaging or sonographic technique, or represent varying ranges of structure-specific normal including a spectrum of findings associated with aging in asymptomatic subjects. When an imaging finding of questionable significance is encountered, it is critical that the interpreting radiologist make every attempt to review any relevant clinical information in an effort to determine whether the imaging findings in question may account for the patient's presenting symptomology. In order to accurately diagnose true pathology at wrist imaging, it is imperative that the radiologist be familiar with the pitfalls discussed throughout this manuscript that may mimic disease. This familiarity will allow the radiologist to provide a more useful report for referring providers focusing on true pathology while eliminating potentially confusing or misleading findings which are inconsistent with the patient's clinical presentation.","PeriodicalId":39381,"journal":{"name":"Topics in Magnetic Resonance Imaging","volume":"29 5","pages":"263-272"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/RMR.0000000000000254","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38560019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The TFCC comprises a complicated group of fibrocartilaginous and ligamentous structures at the ulnar aspect of the wrist that plays an important role in wrist biomechanics. It is the main stabilizer of the distal radioulnar and ulnocarpal joints and functions to distribute compressive forces at the ulnocarpal joint during axial loading. Derangement of the TFCC is the most common source of ulnar-sided wrist pain. Imaging plays an important role in the diagnosis and management of these lesions. The TFCC can anatomically be divided into proximal and distal parts to emphasize the role that the proximal TFCC has in stabilizing the distal radioulnar joint. Tears can be divided into traumatic and degenerative categories using the Palmer classification. Further subclassification based on the location for traumatic tears and the degree of derangement in degenerative tears guides clinical management. The vascular anatomy is important in determining management options for various lesions. A detailed understanding of the normal anatomy of the TFCC, imaging limitations and pitfalls, the Palmer classification system, and current treatment options is critical to the accurate and clinically useful interpretation of radiologic examinations of the TFCC.","PeriodicalId":39381,"journal":{"name":"Topics in Magnetic Resonance Imaging","volume":"29 5","pages":"237-244"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/RMR.0000000000000253","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38463249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pharmacological methods often fail to achieve acceptable level of analgesia in these patients, especially during burn wound dressing and debridement. Virtual reality (VR) distraction is a promising analgesic technique that progressed significantly in the last decade with development of commercially available, low-cost, high-resolution, wide field-of-view, standalone VR devices that can be used in many clinical scenarios. VR has demonstrated clinical benefit as an adjunctive analgesic during burn wound dressing and other painful medical procedures. The technique has proven useful also in preparing patients for magnetic resonance imaging scans, particularly in claustrophobic patients. Modulation of pain-related brain activity at cortical and subcortical levels by VR, and its correlation with subjective improvement in various laboratory and clinical pain experiences has been demonstrated using multiple functional brain imaging studies including functional magnetic resonance imaging and brain perfusion single photon emission computed tomography.","PeriodicalId":39381,"journal":{"name":"Topics in Magnetic Resonance Imaging","volume":"29 4","pages":"203-208"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/RMR.0000000000000248","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38021376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article discusses practical, patient-oriented considerations that are helpful for radiologists contemplating ways to improve the MRI experience for patients. Patient friendly scanner properties are discussed, with an emphasis on literature findings of effectiveness in mitigating patient claustrophobia, other anxiety, or motion and on reducing scan incompletion rates or need for sedation. As shorter scanning protocols designed to answer specific diagnostic questions may be more practical and tolerable to the patient than a full-length standard-of-care examination, a few select protocol adjustments potentially useful for specific clinical settings are discussed. In addition, adjunctive devices such as audiovisual or other sensory aides that can be useful distractive approaches to reduce patient discomfort are considered. These modifications to the MRI scanning process not only allow for a more pleasant experience for patients, but they may also increase patient compliance and decrease patient movement to allow more efficient acquisition of diagnostic-quality images.","PeriodicalId":39381,"journal":{"name":"Topics in Magnetic Resonance Imaging","volume":"29 4","pages":"181-186"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1097/RMR.0000000000000247","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38020422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These procedures are commonly viewed as ‘‘high-tech’’ because of their advanced, complex technologies that in turn can be intimidating, uncomfortable, and unfamiliar to many patients. Advanced procedures often demand a high degree of patient cooperation in order to achieve their intended objective of delivering highquality care. Not infrequently, invasive and pharmacologic means are required to ensure patients’ cooperation during the imaging and imaging-guided procedures. In this Special Edition, we provide a succinct overview of the experience using various integrative medicine strategies of noninvasive and nonpharmacologic approaches for diagnostic imaging and image-guided therapy, and their efficacy and mode of action, including psychology and neuroscience perspective. We envision the Special Edition’s focus on integrative medicine approaches to bring together, in an ‘‘integrative’’ and multi-disciplinary way, both advanced technologies and patient-centered integrative health and psychology concepts to optimize the success of advanced diagnostic imaging studies and imaging-guided therapies. This is relevant and innovative and may offer insights beyond conventional wisdom and beyond the scope of many current scientific and medical journals.
