Role of Imaging in Acute Ischemic Stroke
Publication date: Available online 28 February 2018Source: Seminars in Ultrasound, CT and MRIAuthor(s): Andrew A. Pavlina, Rupa Radhakrishnan, Achala S. VagalRapid multimodal imaging is essential in the workup and management of acute ischemic stroke. Early parenchymal findings on noncontrast computed tomography or standard magnetic resonance imaging are used to triage patients for intravenous thrombolysis and to provide insight on prognosis. In the wake of recent endovascular stroke trials, advanced techniques including perfusion imaging and noninvasive vascular imaging are becoming important tools to guide potential endov...

Brain Death: Diagnosis and Imaging Techniques
Publication date: Available online 2 March 2018Source: Seminars in Ultrasound, CT and MRIAuthor(s): Tanvir Rizvi, Prem Batchala, Sugoto MukherjeeBrain death (BD) is an irreversible cessation of functions of the entire brain, including the brainstem. The diagnosis of BD is made on clinical grounds and neurologic examination. In the United States, clinical criteria set by the American Academy of Neurology (AAN) emphasize 3 specific clinical findings to confirm BD, which include coma, absence of brainstem reflexes and apnea. Ancillary tests are needed when neurologic examination or apnea test cannot be performed. AAN recommen...

Multidetector CT Imaging of Bowel and Mesenteric Injury: Review of Key Signs
Publication date: Available online 23 March 2018Source: Seminars in Ultrasound, CT and MRIAuthor(s): Andrew E. Bennett, Robin B. Levenson, Jon D. DorfmanIn contemporary practice, multidetector computed tomography plays a critical role in the diagnostic evaluation of patients with suspected acute mesenteric and bowel trauma. Although less common than solid organ injuries, it may be seen in up to 5% of blunt trauma patients. Evaluation with CT remains challenging even with improvements in technology. The major imaging signs of mesenteric and bowel trauma and what is known about their applicability in clinical practice are re...

Pediatric Elbow Injuries
This article seeks to improve diagnostic accuracy of these elbow injuries by reviewing the secondary ossification centers in the elbow in the pediatric population, followed by a discussion of commonly encountered acute and chronic fractures, dislocations or other injuries. While many elbow injuries are diagnosed with radiographs, there are situations where imaging with computed tomography, ultrasonography, and magnetic resonance imaging are essential in the diagnosis of these injuries.

Imaging and Management of Thoracic Trauma
Publication date: Available online 26 March 2018Source: Seminars in Ultrasound, CT and MRIAuthor(s): Alex Newbury, Jon D. Dorfman, Hao S. LoAbstractThoracic injury results from penetrating and blunt trauma and is a major contributor to overall trauma morbidity and mortality in the United States. Modern imaging algorithms utilize ultrasound, CXR, and CT with intravenous contrast to accurately diagnose and effectively treat patients with acute thoracic trauma. This review focuses on the etiologies, signs and symptoms, imaging, and management of several life-threatening thoracic injuries including tracheobronchial rupture, pu...

Point-of-Care Ultrasound in Trauma
Publication date: Available online 29 March 2018Source: Seminars in Ultrasound, CT and MRIAuthor(s): Timothy Gleeson, David BleharThe use of point-of-care ultrasound in trauma is widespread. Focused Assessment with Sonography for Trauma examination is a prototypical bedside examination used by the treating provider to quickly determine need for intervention and appropriate patient disposition. The role of bedside ultrasound in trauma, however, has expanded beyond the Focused Assessment with Sonography for Trauma examination. Advancements in diagnostics include contrast-enhanced ultrasound, thoracic, and musculoskeletal app...

Diffuse Liver Diseases: Role of imaging
Publication date: April 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 2Author(s): Adele Taibbi, Dario Picone, Massimo Midiri, Ludovico La Grutta, Tommaso Vincenzo BartolottaNowadays, the most common imaging techniques allow to study focal liver lesions with high diagnostic accuracy but a relatively recent emerging field of interest is represented by diffuse liver disease. They include a variegated series of storage and metabolic pathologies (ie, iron overload disorders and steatosis) requiring a precise diagnosis not always possible at imaging due to the overlapping of findings at conventional ultrasound...

Abdominal Wall Masses: CT Findings and Clues to Differential Diagnosis
Publication date: April 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 2Author(s): Gabriela Gayer, Christian ParkThe abdominal wall does not comprise a distinct organ, and is often cursorily evaluated on CT. However, it is affected by many different pathological processes. These may be categorized according to their underlying etiology—trauma, infection or inflammation, iatrogenic and neoplastic process—or according to the abdominal wall layer they affect. We chose instead to group these lesions into 6 distinct categories based on their CT characteristic density: solid, infiltrative, hypervascular, fl...

Publication date: April 2018Source: Seminars in Ultrasound, CT and MRI, Volume 39, Issue 2Author(s): Kunal Kothari, John J. HinesThe kidneys are paired intra-abdominal organs which provide essential functions and maintain homeostasis throughout the human body. Numerous disease processes affect the kidneys and cause acute renal dysfunction or other potentially catastrophic complications. These conditions can be broadly categorized into obstructive, infectious, hemorrhagic, traumatic, and vascular diseases. Imaging plays a vital role in the work-up and diagnosis of acute and emergent renal conditions. Evaluation of emergent ...
