Masses of the hand and wrist, a pictorial review.

The majority of hand and wrist soft tissue and osseous masses are benign, commonly presenting as palpable or incidentally detected lesions. When analyzing such a mass, one of the radiologist's most important objectives is to determine if the lesion requires a biopsy. In this review, the imaging appearances of 14 different types of masses are presented with pathologic correlation.

Osseous injuries of the foot: an imaging review. Part 2: the midfoot.

Injuries to the foot are a common cause for presentation to the emergency department (ED), and imaging is often used to aid in the diagnosis. The foot can be divided into three distinct anatomic regions: the forefoot, midfoot and hindfoot. Our manuscripts comprise a three-part imaging review in which we address the use of radiography as well as advanced imaging modalities.

Sacrum and Coccyx Radiographs Have Limited Clinical Impact in the Emergency Department.

Objective: The purpose of this study was to determine the yield and clinical impact of sacrum and coccyx radiographs in the emergency department (ED).

Materials And Methods: Consecutive sacrum and coccyx radiographs obtained in the EDs of four hospitals over a 6-year period were categorized as positive for acute fracture or dislocation, negative, or other. Five follow-up metrics were analyzed: follow-up advanced imaging in the same ED visit, follow-up advanced imaging within 30 days, new analgesic prescriptions, clinic follow-up, and surgical intervention within 60 days.

Benign and malignant tumors of the foot and ankle.

Pain and focal masses in the foot and ankle are frequently encountered and often initiate a workup including imaging. It is important to differentiate benign lesions from aggressive benign or malignant lesions. In this review, multiple examples of osseous and soft tissue tumors of the foot and ankle will be presented.

A systematic, multimodality approach to emergency elbow imaging.

The elbow is a complex synovial hinge joint that is frequently involved in both athletic and nonathletic injuries. A thorough understanding of the normal anatomy and various injury patterns is essential when utilizing diagnostic imaging to identify damaged structures and to assist in surgical planning. In this review, the elbow anatomy will be scrutinized in a systematic approach.

Gastrointestinal Stromal Tumors: Imaging Features Before and After Treatment.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, with most occurring in the stomach. GISTs may present with clinical symptoms (eg, gastrointestinal bleeding) or may be found incidentally at surgery, endoscopy, or imaging. At initial staging, GISTs often appear as well-circumscribed, round, solid masses.

MRI of the hand and fingers.

Injuries of the hand and fingers occur commonly in professional athletes as well as weekend warriors. Magnetic resonance imaging plays a vital role in the evaluation of these injuries for accurate diagnosis, preoperative planning, potential complication, and follow-up during rehabilitation. A detailed analysis of these smaller structures necessitates optimal imaging quality coupled with comprehensive knowledge of the imaging anatomy.

Diagnostic utility of MRI and MR arthrography for detection of ligamentum teres tears: a retrospective analysis of 187 patients with hip pain.

Objective: The purpose of this study was to compare the diagnostic utility of MRI and MR arthrography for ligamentum teres tears in patients with hip pain.

Materials And Methods: This is a retrospective study involving 187 patients who underwent MRI or MR arthrography for hip pain. This study included 103 male and 84 female patients with average age of 39 years.

Radiographic evaluation of INBONE total ankle arthroplasty: a retrospective analysis of 30 cases.

Objectives: The objectives of this work were to retrospectively describe the radiographic assessment of INBONE total ankle arthroplasty in 30 patients using validated linear and angular measurements and to correlate these findings with the final surgical outcome over a 2-year follow-up period.

Materials And Methods: Thirty consecutive patients (21 females, nine males; mean age, 64.8 years) underwent INBONE total ankle arthroplasty during 2007-2011.

Imaging of impingement lesions in the ankle.

Ankle impingement and instability are well-recognized complications of ankle sprain. Ankle impingement is an important cause of chronic ankle pain in active populations, particularly in the professional athlete. Depending on anatomical location and the structures involved, impingement syndromes are classified into anterolateral, anterior, posterior, posteromedial, and anteromedial types.

Magnetic resonance imaging of anatomical variations in the knee. Part 2: miscellaneous.

Magnetic resonance imaging is the modality of choice for investigation of internal derangement of the knee. The reporting radiologist must be familiar with both normal anatomy and anatomical variants within the knee, in order to avoid mis-diagnosis, over-investigation and unnecessary intervention. This article reviews the recognised anatomical variants of the non-ligamentous/musculotendinous structures of the knee, their anatomy, incidence and typical appearances on MRI.

Magnetic resonance imaging of anatomical variations in the knee. Part 1: ligamentous and musculotendinous.

Magnetic resonance imaging (MRI) is now the modality of choice for the investigation of internal derangement of the knee. Technological advances, including the wider availability of stronger magnets and new sequences, allows improved visualisation of smaller structures. Normal variants must be recognised as such, so that both over-investigation and mis-diagnosis are avoided.

Imaging-guided percutaneous biopsy of pathologic fractures: a retrospective analysis of 129 cases.

Objective: The purpose of our study was to determine the diagnostic performance of imaging-guided percutaneous needle core biopsy and the factors associated with a nondiagnostic biopsy in patients with a pathologic fracture of the appendicular skeleton.

Materials And Methods: A retrospective audit was performed of 129 consecutive patients presenting with a pathologic fracture. All patients underwent percutaneous needle core biopsy using CT (n = 98), fluoroscopy (n = 15), or ultrasound (n = 16) guidance.

Percutaneous treatment of insufficiency fractures : principles, technique and review of literature.

Insufficiency fractures of the pelvis, sacrum, spine, and long bones are painful, debilitating, and are common consequences of osteoporosis. Conventional treatment for these fractures varies from conservative therapy to surgery with plate and screw fixation. The former fails to address the underlying problem of fracture and frequently does not alleviate symptoms, while the latter is invasive and not always possible in older populations with low bone density and numerous co-morbidities.
