 | Couldwell, William T. | False-negative magnetic resonance angiography with extracranial internal carotid artery stenosis: a report of two cases and review of the literature | Magnetic resonance angiography (MRA) is increasingly used as a noninvasive means to assess internal carotid artery (ICA) stenosis. When used alone, however, MRA may not be sufficiently accurate in certain settings to determine whether ICA disease meets surgical criteria. Although MRA has been recogn... | Internal carotid artery stenosis; Magnetic resonance angiography | 2005 |

 | Couldwell, William T. | Thrombosed basilar apex aneurysm presenting as a third ventricular mass and hydrocephalus | Aneurysms presenting as third ventricular masses are uncommon; most are giant aneurysms arising from the basilar apex. We present a case of a thrombosed basilar apex aneurysm presenting as a third ventricular mass and hydrocephalus in a 55-year-old man. The case is unique in the literature as the an... | Basilar apex aneurysm; Ventricular mass; Third ventriculostomy | 2005 |

 | Couldwell, William T.; Gottfried, Oren N. | Distal ventriculoperitoneal shunt failure secondary to clostridium difficile colitis | Distal ventriculoperitoneal shunt obstruction is typically associated with cerebrospinal fluid (CSF) infection, fluid pseudocysts, bowel obstruction, bowel perforation, or improper shunt placement in the abdomen. We describe a unique etiology for distal shunt obstruction secondary to Clostridium di... | 2005-01-01 | |

 | Gerig, Guido | Hypothesis testing with nonlinear shape models | We present a method for two-sample hypothesis testing for statistical shape analysis using nonlinear shape models. Our approach uses a true multivariate permutation test that is invariant to the scale of different model parameters and that explicitly accounts for the dependencies between variables. ... | 2005-01-01 | |

| Gerig, Guido | Unbiased atlas formation via large deformations metric mapping | The construction of population atlases is a key issue in medical image analysis, and particularly in brain mapping. Large sets of images are mapped into a common coordinate system to study intrapopulation variability and inter-population differences, to provide voxelwise mapping of functional sites,... | Computational anatomy; Brain atlases; Image metric space | 2005-01-01 |
