BACKGROUND: Magnetic resonance imaging (MRI) is used as an adjunct to ultrasound in prenatal imaging, the latter being the standard technique in obstetrical medicine. METHODS: Initial results demonstrate the ability to visualise the foetal skeleton and muscles on MRI, and highlight the potentially useful applications for foetal MRI, which has ...

Assuming thromboembolic events to be the origin of silent strokes during cerebral digital subtraction angiography (DSA), antiplatelet therapy with acetylsalicylic acid (ASA) should significantly reduce the risk for DSA-related silent stroke. The aim of this retrospective analysis was to assess whether ASA does prevent DSA-related silent stroke in terms of ...

Spondylitis is the most common osseous manifestation of Mycobacterium tuberculosis infection. Although treatable, it continues to cause significant mortality and morbidity. Early diagnosis through familiarity with its imaging characteristics is essential to permit rapid treatment and prevent potential life-limiting consequences. In this review, we demonstrate the key magnetic resonance imaging ...

A recent Cochrane Review has demonstrated that emergency ultrasonography decreases the amount of computerised tomographic scans in blunt abdominal trauma.13 However, there is no systematic review that has evaluated the utility of the Focused Assessment with Sonography for Trauma(FAST) exam in penetrating torso trauma. We systematically reviewed the medical literature ...

The role of magnetic resonance imaging in evaluating patients with inflammatory arthritides has evolved with the recent introduction of drugs capable of modifying disease activity and natural history.

ABSTRACT: The following article reviews the role of magnetic resonance imaging (MRI) in patients with idiopathic inflammatory myopathies (IIMs), focusing on the 3 major types of IIM: polymyositis, dermatomyositis, and inclusion-body myositis. After a brief introduction with general information about IIM, we will discuss the reasons why MRI plays an ...

Traumatic brain injury (TBI) is a common cause of neurological damage and disability. Conventional imaging (CT scan or MRI) is highly sensitive in detecting lesions and provides important clinical information regarding the need for acute intervention. However, abnormalities detected by CT scan or conventional MRI have limited importance in the ...

Multidetector computed tomography (MDCT) has emerged as the imaging modality of choice for evaluating the abdomen and pelvis in trauma patients. MDCT readily detects injury of the solid organs as well as direct and indirect features of bowel and/or mesenteric injury-an important advance given that unrecognized bowel and mesenteric injuries ...

Concussion or mild traumatic brain injury (mTBI) is a condition that affects hundreds of thousands of patients worldwide. Understanding the pathophysiology of this disorder can help manage its acute and chronic repercussions. Immediately following mTBI, there are several metabolic, hemodynamic, structural, and electric changes that alter normal cerebral function. These ...

We propose an automated method for preoperative trajectory planning of deep brain stimulation image-guided neurosurgery. Our framework integrates multi-modal MRI analysis (T1w, SWI, TOF-MRA) to determine an optimal trajectory to DBS targets (subthalamic nuclei and globus pallidus interna) while avoiding critical brain structures for prevention of hemorrhages, loss of function ...

Computed tomography (CT) scanning is a vital imaging technique in selecting patients for nonoperative management of civilian penetrating abdominal trauma. This has reduced the rate of nontherapeutic laparotomies and associated complications. Battlefield abdominal injuries conventionally mandate laparotomy, and with the advent of field deployable CT scanners it is unclear whether ...

Noncontrast computed tomography (CT) provides important diagnostic information for patients with traumatic brain injury. A systematic approach to image interpretation optimizes detection of pathologic air, fractures, hemorrhagic lesions, brain parenchymal injury, and abnormal cerebrospinal fluid spaces. Bone and brain windows should be reviewed to enhance injury detection. Findings of midline ...

Traumatic brain injury (TBI) has a poorly understood pathology. Patients suffer from a variety of physical and cognitive effects that worsen as the type of trauma worsens. Some noninvasive insights into the pathophysiology of TBI are possible using magnetic resonance imaging (MRI), computed tomography (CT), and many other forms of ...

The Canadian CT Head Rule was developed to allow physicians to be more selective when ordering computed tomography (CT) imaging for patients with minor head injury. We sought to evaluate the effectiveness of implementing this validated decision rule at multiple emergency departments. We conducted a matched-pair cluster-randomized trial that compared ...

Four injuries and two reinjuries of the myotendinous junction of the LD ...

Delayed enlargement of a traumatic cerebral contusion can occur subsequent to an initial CT scan, and this can lead to neurological deterioration, brain herniation, and death. Herein, we describe the case of a 76-year-old male who experienced an intracerebral hemorrhage subsequent to a fall and whose injury worsened over time. ...

Paediatric head injury is a common presentation to emergency departments (ED), and the 2007 National Institute for Health and Clinical Excellence head injury guidelines included a paediatric section to deal with this.
