Isolated Mediastinal Goitre: A Case Report.

Unlabelled: Retrosternal goitre is not an uncommon entity owing to various reasons - ignorance, fear, lack of access to safe surgical technique, incomplete thyroid surgery. Retrosternal goitre could have varied presentations, especially in cases with prior thyroid surgery. Fifty-three-year-old female with history of thyroid surgery 20 years back presented with a large neglected anterior neck swelling.

Delineation of the ischemic stroke lesion based on watershed and relative fuzzy connectedness in brain MRI.

Precise segmentation of stroke lesions from brain magnetic resonance (MR) images poses a challenging task in automated diagnosis. In this paper, we proposed a new method called watershed-based lesion segmentation algorithm (WLSA), which is a novel intensity-based segmentation technique used to delineate infarct lesion in diffusion-weighted imaging (DWI) MR images of the brain. The algorithm was tested on a series of 142 real-time images collected from different stroke patients reported at IMS and SUM Hospital.
