BGrowth: an efficient approach for the segmentation of vertebral compression fractures in magnetic resonance imaging

Segmentation of medical images is a critical issue: several process of analysis and classification rely on this segmentation. With the growing number of people presenting back pain and problems related to it, the automatic or semi-automatic segmentation of fractured vertebral bodies became a challenging task. In general, those fractures present several regions with non-homogeneous intensities and the dark regions are quite similar to the structures nearby. Aimed at overriding this challenge, in this paper we present a semi-automatic segmentation method, called Balanced Growth (BGrowth). The experimental results on a dataset with 102 crushed and 89 normal vertebrae show that our approach significantly outperforms well-known methods from the literature. We have achieved an accuracy up to 95% while keeping acceptable processing time performance, that is equivalent to the state-of-the-artmethods. Moreover, BGrowth presents the best results even with a rough (sloppy) manual annotation (seed points).Comment: This is a pre-print of an article published in Symposium on Applied Computing.

Enhanced MR imaging of the shoulder, and sternoclavicular and acromioclavicular joint arthritis in primary hemochromatosis.

Shoulder arthritis is a common feature of hemochromatosis. However, a combination of sternoclavicle (SC) and acromioclavicular (AC) joint involvement associated with shoulder is uncommonly seen. We describe the MR imaging findings of the shoulder and SC and AC joint in a patient with primary hemochromatosis. MRI of the left shoulder revealed inflammatory arthritis and 1-cm erosion of the humeral head, enlargement of the anterior glenoid labrum and formation of glenoid labral ovoid mass due to iron deposit. MRI of the AC joint showed inflammation and erosion with joint fluid. Significant contrast enhancement was noted at the SC joint due to inflammation
