Injuries to lower extremity nerves range from contusions and stretch injuries that will often resolve without interventions to traumatic disruptions requiring surgical procedures, including neurolysis, repair or even nerve grafting. While clinical examination and tools such as electromyography will often help to localize the site of injury, imaging is a critical tool in determining the extent and degree of nerve injury in the setting of trauma. Modalities such as ultrasound and radiography are often useful, but MRI is considered the primary imaging modality for assessing the extent and degree of nerve injury. Specialized techniques such as MR neurography tailored to the needs of individual patients can provide important and detailed information in support of clinical decision making and presurgical planning. In this paper, we will review the anatomy of peripheral nerves of the lower extremity, mechanisms of injury affecting nerves and provide guidance for the use of MRI correlated with validated classification systems in assessing injuries affecting the nerves of the lower extremities.</div>","PeriodicalId":49541,"journal":{"name":"Seminars in Ultrasound Ct and Mri","volume":"44 4","pages":"Pages 347-363"},"PeriodicalIF":1.1,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9818988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lesser metatarsophalangeal joint plantar plate degeneration and tear typically presents as an attritional pattern of capsuloligamentous deficiency in middle-aged patients, whereas first metatarsophalangeal joint capsuloligamentous injury is typically acute and occurs in younger adult athletes engaged in sports involving repetitive running and jumping. Consequently, considerations regarding surgical decision-making also differ. Knowledge of the anatomy, pathophysiological basis, common patterns, grading and classification of these injuries, and indications for surgery, will aid imaging interpretation in the preoperative setting. The acuity and extent of injury, tissue quality and functional requirements of the patient (such as timely return to sport) influence clinical decision-making with respect to conservative versus surgical management and are informed by the use of optimized multimodal imaging.

Computed tomography and magnetic resonance imaging are the key imaging modalities used in the detection of BM. Advanced imaging techniques including proton magnetic resonance spectroscopy, magnetic resonance perfusion, diffusion weighted imaging, and diffusion tensor imaging may aid in arriving at the correct diagnosis, in particular cases, such as newly diagnosed solitary enhancing brain lesions in patients without known malignancy. Imaging is also performed to predict and/or assess the efficacy of treatment, and to differentiate residual or recurrent tumors from therapy-related complications. Furthermore, the recent advent of artificial intelligence is opening up a vast scenario for the analysis of quantitative information deriving from neuroimaging. In this image-rich review, we provide an up-to-date overview on the application of imaging in patients with BM.

In the postprocessing study phase, virtual monochromatic images and virtual-non-contrast (VNC) images, also permits reduction of dose exposure by eliminating the precontrast acquisition scan. Moreover, in virtual monochromatic images, the iodine contrast increases when the energy level decreases resulting in better visualization of hypervascular lesions and in a better tissue contrast between hypovascular lesions and the surrounding parenchyma; thus, allowing for reduction of required iodinate contrast material, especially important in patients with renal impairment. All these advantages are particularly important in oncology, providing the possibility of overcoming many SECT imaging limits and making CT examinations safer and more feasible in critical patients.
