Ultrasonography of post-traumatic soft-tissue lesions.

This article highlights the varied uses of ultrasound for detection of trauma to soft tissues. The emphasis is on the diagnosis of tendon and muscle disruptions. Detection of soft-tissue foreign bodies by ultrasound, an important recent innovation, is also reviewed. Miscellaneous potential applications of ultrasound for diagnosing meniscal injuries, cartilage integrity, epidermoid cysts, and traumatic vascular malformations are discussed briefly. Ultrasound is efficacious because of its low cost, noninvasiveness, wide availability, and accuracy.

Pigmented villonodular synovitis: a report of MR imaging in two cases.

Although magnetic resonance (MR) imaging has been used to evaluate many musculoskeletal lesions, the MR appearance of pigmented villonodular synovitis (PVNS) has not been described in detail. The authors describe two cases of PVNS in the knee imaged with both computed tomography and MR. In both cases parts of each lesion had very low signal intensity on both short repetition time (TR)/echo time (TE) sequences and long TR/TE sequences. Other portions of both lesions had intermediate signal intensity (equal to or higher than that of muscle but lower than that of fat) on short TR/TE sequences and increasing signal intensity on longer TR/TE images. In one case, the lesion also had a cystic component that showed MR changes typical of complex fluid. The authors propose that the MR signal characteristics demonstrated in these cases may be explained by the unique tissue components of the lesion, particularly hemosiderin and fat.

Imaging techniques in the evaluation of adenocarcinoma of the pancreas.

Adenocarcinoma of the pancreas is a highly malignant neoplasm that presents late and carries a dismal prognosis. Despite technical advances, the various imaging modalities used to evaluate and stage a pancreatic adenocarcinoma have not had a significant impact on survival rates. This article describes the various imaging modalities used to image and stage an adenocarcinoma of the pancreas and reviews their relative accuracy and limitations in diagnosing and staging this carcinoma. We conclude that for appropriate staging of adenocarcinoma of the pancreas, the combination of a computed axial tomography scan and an endoscopic ultrasound represents an efficient and cost-effective approach.
