BACKGROUND The technique of BAC is attractive because the balloon theoretically allows for (1) "control" of blood flow in the vessel; (2) improved stability of the microcatheter in the aneurysm; (3) denser packing with coils; and (4) improved delineation of the neck of the aneurysm. The purpose of this communication is to document our outcomes with this(More)
A 43-year-old woman developed right frontal headache and decreased vision in her OD 14 months after treatment of an intracranial aneurysm by wrapping with cotton gauze. A junctional visual field defect was present, and an MRI revealed a contrast-enhancing mass involving the right optic nerve, lateral chiasm, optic tract, and cavernous sinus. Biopsy(More)
The spinal cord is a vital organ that serves as the only communication link between the brain and the various parts of the body. It is vulnerable to traumatic spinal cord injury and various diseases such as tumors, infections, inflammatory diseases and degenerative diseases. The exact segmentation and localization of the spinal cord are essential to(More)
In this paper we propose a robust and fully automated lumbar herniation diagnosis system based on clinical MRI data which will not only aid a radiologist to make a decision with increased confidence, but will also reduce the time needed to analyze each case. Our method is based on three steps : 1) We automatically label the five lumbar intervertebral discs(More)
Lower back pain is widely prevalent in the world today, and the situation is aggravated due to a shortage of radiologists. Intervertebral disc disorders like desiccation, degeneration and herniation are some of the major causes of lower back pain. In this paper, we propose a robust computer-aided herniation diagnosis system for lumbar MRI by first(More)
Lower Back Pain (LBP) is the second most common neurological ailment in the United States after the headache. It costs over $100 Billion annually in treatment and related rehabilitation costs including worker compensation. In fact, it is the most common reason for lost wages and missed work days. Degenerative Disc Disease (DDD) is the major abnormality that(More)
As there is an increasing need for the computer-aided effective management of pathology in lumbar spine, we have developed a computer-aided diagnosis and characterization framework using lumbar spine MRI that provides radiologists a second opinion. In this paper, we propose a left spinal canal boundary extraction method, based on dynamic programming in(More)
BACKGROUND The International Subarachnoid Aneurysm Trial has indicated that endovascular management of acutely ruptured aneurysms may be superior to surgery. Clearly poor results ensue from both forms of treatment, and some of these are because of technical complications (not just poor patient status). This observational study was performed to determine the(More)
A Computer-aided diagnosis (CAD) system aims to facilitate characterization and quantification of abnormalities as well as minimize interpretation errors caused by tedious tasks of image screening and radiologic diagnosis. The system usually consists of segmentation, feature extraction and diagnosis, and segmentation significantly affects the diagnostic(More)
Lumbar Intervertebral disc diseases are the main cause of lower backpain (LBP). Desiccation is a common disease resulting from different causes and ultimately most people are affected by desiccation at some age. We automate the diagnosis of desiccation by processing localized lumbar intervertebral discs. We utilize a Gibbs distribution to model the(More)
