Abstract

This study aims to assess the role & efficacy of Diffusion-weighted imaging in evaluation of intracranial pathologies. After achieving patient's informed consent and Institutional review board approval, total 80 cases of various intracranial pathologies of all age groups and either sex were evaluated. All MR images were obtained with a 1.5-T superconducting system (Siemens Medical Healthcare) using a circularly polarized head coil. Out of 80 cases, 2 cases showed no findings on MR (conventional and diffusion MR), and a total of 125 lesions was found in 78 cases. Infarct (68%) was the commonest lesion seen in our study. Of these, acute infarcts which presented within 24 hours of onset of ictus represented 70%, Hyper-acute infarcts (9.41%), Sub-acute infarcts (10.5%) and Chronic infarcts (9.41%) were less common. In cases of acute infarcts of the total 60 lesions, Conventional MR (T2WI) and FLAIR could detect 96.6% of the lesions and diffusion MR had 100% detection rate for acute infarcts. Diffusion MR, conventional MR and FLAIR had equal (100%) detection rate. Both conventional and diffusion MR (100%) had equal detection rate for chronic infarcts. Among the non-infarct lesions, Meningioma were most common with 10 lesions (8%) de...Continue Reading

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.
