Development, Validation, And Diagnostic Performance Of A Novel Radiomic Model For Predicting Prostate Cancer Recurrence, Linda M. Huynh

Theses & Dissertations

Multi-parametric magnetic resonance imaging (MP-MRI)-derived radiomics have been shown to capture sub-visual patterns for the quantitative characterization of prostate cancer (PC) phenotypes. The present dissertation seeks to develop, evaluate, and compare the performance of an MRI-derived radiomic model for the prediction of PC recurrence following definitive treatment with radical prostatectomy (RP).

MP-MRI was obtained from 339 patients who had a minimum of 2 years follow-up following RP at three institutions. The prostate was manually delineated as the region of interest and 924 radiomic features were extracted. All features were evaluated for stability via intraclass correlation coefficient (ICC) and image normalization …

Multimodal Investigations For The Identification Of Surgically Relevant Brain Areas, Kevin Tyner

Theses & Dissertations

Epilepsy is a neurological disease leading to recurrent and unpredictable seizures. Patients can be diagnosed as focal onset, where the seizure focus resides in one hemisphere; generalized onset, where seizure foci reside in both hemispheres; or unknown onset. Anti-seizure medications are the first line of treatment, and those whose seizures cannot be controlled with medication are diagnosed with drug-resistant epilepsy (DRE). For patients diagnosed with focal onset epilepsy to achieve seizure freedom, surgical resection of the epileptogenic zone (EZ), the region of the brain that is both necessary and sufficient for initiating seizures, is required. The EZ is a theoretical …
