ReviewHigh-resolution ultrasound in assessment of the gastrointestinal tract.
Ultrasound (US) is frequently the first investigation performed in patients presenting with a variety of abdominal symptoms, and there is a growing appreciation of its value in a wide range of gastrointestinal (GI) disorders. The advantages of US are that it is quick, safe, readily available, noninvasive, and avoids ionizing radiation. ⋯ Its real time capabilities are of particular usefulness in abdominal conditions; clinical correlation is instant and features such as peristalsis and bowel compressibility can be readily assessed. This review describes and illustrates the current role of high-resolution transabdominal US in the detection of GI pathology with discussion on some of the applications of endoscopic ultrasound (EUS) as they relate to this topic.

ReviewComputed tomography (CT) and magnetic resonance imaging (MRI) of pleural masses.
Depending on the location, size, and underlying histologic features, pleural masses may produce a large spectrum of findings. While a number of imaging modalities may be used, plain chest radiographs remain the most common examination in the initial assessment of these patients. ⋯ For the purpose of this review, localized pleural masses and diffuse pleural masses are discussed separately. Among the various pleural masses, metastatic disease represents the most frequent neoplasm.

Review Comparative StudyMagnetic resonance imaging of osteomyelitis.
Early diagnosis and detection of osteomyelitis and differentiation of soft-tissue infection from bone involvement is a difficult clinical and imaging problem. Magnetic resonance imaging has proven to be as sensitive as bone scintigraphy in the early detection of osteomyelitis, and, with its superior spatial resolution, MR is often more specific than planar scintigraphy in differentiating bone from soft-tissue infection and separating arthritis, cellulitis, and soft-tissue abscess from osteomyelitis. ⋯ MRI has a large role in evaluating the presence and extent of spondylitis and epidural abscess and certain distribution features may help recognize tuberculous spondylitis. Gadolinium-enhanced MR could be helpful in delineating the meninges and demonstrating the border and extent of epidural abscesses.

ReviewRadiography of acromioclavicular dislocation and associated injuries.
The superficial location of the acromioclavicular joints in the human skeleton makes it vulnerable to several kinds of disruptive forces, resulting in a variety of injuries. In this review, we describe different types of acromioclavicular dislocation and associated fractures. We emphasize the radiographic features and methods of detecting the lesions otherwise unnoticed along with the mechanisms, the frequency, and the pathology of the injuries.

Magnetic resonance imaging is the study of choice in the evaluation of infectious and inflammatory disease of the spinal cord and spinal column. Not only is the multiplanar imaging a distinct advantage over other modalities, but direct visualization of the soft tissues, including the spinal cord, paraspinal musculature, and disk, is present. ⋯ Subjects covered include disk space infections, epidural abscess, meningitis, arachnoiditis, and inflammatory mimics of disk space infections. Suggested imaging protocols are stated.
