Skin: MR imaging findings at middle field strength

Radiology

Abstract

Skin tumors were staged at magnetic resonance (MR) imaging on a 0.5-T (middle-field-strength) system, with use of a 2-cm-diameter receive-only surface coil. T1- and T2-weighted spin-echo (SE), fast SE, or three-dimensional (3D) spoiled gradient-recalled imaging were performed in three volunteers and in 13 patients with skin tumors (nine, basal cell carcinoma). MR findings correlated well with histologic findings in the patients (epidermis, relatively hyper-intense on all images; dermis, hypo-intense with irregular interface with subdermal fat). 3D images had the optimal combination of tissue contrast, signal-to-noise ratio, and spatial resolution. MR imaging depicts depth of skin tumor invasion, and findings are complementary to clinical staging.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
