Multislice CT in adult colocolic intussusception: case report and review of the literature.

Intussusception in adults is generally a rare diagnosis and generally different from intussusception in children in terms of clinical presentation, etiology, and incidence (Begos et al., Am J Surg, 173:88-94, 1997; Watson and Bisset, Clin Radiol, 49:723-726, 1994; Felix et al., Am J Surg, 131:723-726, 1976).

MRI characteristics of olecranon bursitis.

Objective: Our aim was to describe the MRI characteristics of septic and nonseptic olecranon bursitis.

Materials And Methods: MRI contrast-enhanced examinations (n = 19) of 35 patients with olecranon bursitis (septic, n = 14; nonseptic, n = 21) were jointly reviewed by two musculoskeletal radiologists. We evaluated bursa size, extent of marginal lobulation, septation, concomitant elbow joint effusion, soft-tissue edema, rim enhancement, soft-tissue enhancement, degree of fluid complexity, definition of bursa margins, presence of edema, thickening of the triceps tendon, and bone marrow edema.

Three-dimensional spiral MR imaging: Application to renal multiphase contrast-enhanced angiography.

A fast MR pulse sequence with spiral in-plane readout and conventional 3D partition encoding was developed for multiphase contrast-enhanced magnetic resonance angiography (CE-MRA) of the renal vasculature. Compared to a standard multiphase 3D CE-MRA with FLASH readout, an isotropic in-plane spatial resolution of 1.4 x 1.
