Retrospective reviews are IRB-approved and monitored studies which allow investigators to access and analyze specific medical data to demonstrate whether a specific treatment was successful or the potential benefit of diagnostic imaging techniques.
- 22518 Review and Survey of CT Followed by MR in the Emergency Room
Summary: Our findings are that the majority of MRI results are in agreement with CT scan results. This study surveys physicians to learn why CT scans are followed up by MRI scans; we plan to show participating physicians the results of the survey to find out if they still would have ordered the MRI given the expectation of low yield for additional clinical information.
- 25412 Evaluation of Yttrium-90 Radioembolization of Primary and Metastatic Liver Tumors Using PET, Octreotide, CT and MR Imaging and Clinical Outcomes
Summary: The purpose of this study is to assess clinical outcomes of patients who have undergone yttrium-90 radioembolization of their primary and metastatic liver tumors as a part of their medically indicated course of treatment.
- 21494 PET and MRI Detection of Alzheimer’s Disease
Summary: PET, MRI scan and clinical data are reviewed and to determine the causes of various types of dementia, including Alzheimer’s Disease. It is our hope that information from this study will aid in accurately diagnosing patients with early Alzheimers disease to allow for more effective treatment.
- 20675 Comparison of Indium-111 Pentetreotide SPECT, Indium-111 Pentetreotide Planar and Magnetic Resonance Imaging in Detecting Hepatic Metastasis in Patients with Neuroendocrine Tumors
Summary: The purpose of this study is to determine whether single photon imaging tomography (SPECT) imaging can detect liver metastases more accurately in comparison to Planar and MRI. The results of the study may change how physicians order future scans for patients with liver metastases
- 20568 Optimization Time of the Octreotide Scan when comparing 4h, 24h, 74h and 7 days images
Summary: The purpose of this study is to compare Octreotide scans performed at various time points to the final diagnoses to show that Octreotide scans performed at the 72 hour and 7 day marks are more effective than scans performed at 4, 24 and 48 hours.
- 18711 Comparison of FDG-PET and Pathological Analysis in the Evaluation of Micrometastases of with Non- Small Cell Lung Carcinoma (NSCLC) in Patients: A Prospective Study of 266 Patients with Positive Mediastinal Lymph Nodes to Findings of PET/CT and the Survival Rate of NSCLC patients with Positive Nodes on PET/CT.
Summary: The purpose of this study is to analyze non-small cell lung carcinoma PET/CT data to determine whether or not PET/CT is a useful tool in the detecting micrometastases.
- 20798 Parathyroid scan and the best imaging modality used for detection of thyroid cancer
Summary: The purpose of this study is to analyze imaging data to determine the best imaging modality to detect thyroid cancer. A parathyroid scan or parathyroid scintigraphy is hypothesized to be the best modality for this.
- 17141 Comparison Between the Presence of Pain and Bone Metastasis Observed on FDG-PET Scans
Summary: This study will evaluate clinical and imaging data on the presence of bone pain in metastatic cancer. This study could potentially improve the diagnosis and treatment of cancer with bone metastasis.
