Dorland's Illustrated Medical Dictionary gives the following definition of dactylitis (deltaalphachitauupsilonlambdaomicronsigma = digit): 'inflammation of a finger or toe'. Although any inflammatory process involving the fingers or toes may be called dactylitis, the term has entered in current use only in some well-defined entities. These differ in the involved tissue ...

CONTEXT: Rotator cuff injuries are common and result in either a tear or tendinopathy within the distal portion of the supraspinatus tendon. Magnetic resonance (MR) imaging shows the injury as a high signal region within the distal tendon. Similarly, a magic-angle effect also appears within healthy patients in this same ...

This article describes calcific tendonitis within the fibular collateral ligament, presumably from hydroxyapatite deposition, a rare cause of acute, severe lateral knee pain. Imaging findings confirmed calcifications in an intact but thickened fibular collateral ligament with adjacent soft-tissue reaction, consistent with calcific tendonitis. Magnetic resonance imaging can appear aggressive, and ...

Anatomic variants of the bones, ligaments, tendons and muscles are frequent findings in imaging of the wrist and hand. Many findings especially changes in the triangular fibrocartilage (TFC) and the interosseous ligaments are asymptomatic, their incidence is increasing with age, and they are frequently found bilaterally. Abnormalities such as increased ...

The accurate diagnosis of stress-induced changes in the foot and ankle requires careful and detailed clinical history and examination. This is of paramount importance in ensuring the correct imaging interpretation and for excluding other differential diagnoses. Advanced imaging (scintigraphy and MR imaging) plays a vital role in the early diagnosis ...
Boutry Nathalie - - 2005
Although conventional radiographs remain the initial mainstay for imaging of the foot in patients with rheumatoid arthritis (RA), magnetic resonance (MR) imaging has afforded the ability to detect early signs of the disease (i.e., synovitis, tenosynovitis, bone lesions, and bursitis), especially at the forefoot. In addition, the relatively symmetric distribution ...

By using three-dimensional magnetic resonance image reconstruction, lateral displacement of the flexor hallucis longus tendon and sesamoid bones was made clearly visible in a living patient. This finding supports a biomechanical model related to disturbed muscle balance at the first metatarsophalangeal joint, which could play an important role in the ...
Ringleb S I - - 2005
Common image-based diagnostic techniques used to detect ankle ligament injuries or the effects of those injuries (e.g., mechanical instability) include magnetic resonance imaging (MRI) and stress radiography. Each of these techniques has limitations. The interpretation of the results obtained through stress radiography, a two-dimensional technique, is highly controversial. MRI can ...
