Study for the Evaluation of the Feasibility of Applying Advanced MRI Scanning in Pediatric Clinical Practice

The purpose of this research study is to evaluate the feasibility in conducting advanced MRI sequences in a pediatric clinical setting. The study will be observational in nature, and will only evaluate the studies of pediatric patients who have already been prescribed an advanced MRI for clinical neurological purposes. The only difference for the subject in participating in this study is that the data and information about their scan can be used and disclosed for research purpo...

In Vivo Evaluation of Image Registration Techniques During Endovascular Repair

Fluoroscopy is traditionally used for guidance of endovascular aortic repair (EVAR). In order to minimize exposure to radiation and nephrotoxic contrast medium, it is possible to generate a navigation road map by registering the intraoperative images with preoperative computed tomography angiograph (CTA). In modern hybrid operating rooms, several commercial solutions for this exists today (e.g. Siemens Syngo iPilot, Phillips Vesselnavigator). In order to register (fuse) the pre...

Follow-up of Myocardial T1 Relaxation Time in Patients With Anderson Fabry Disease

Anderson Fabry disease (AFD) is an X-linked lysosomal storage disorder caused by a deficiency of the enzyme alpha-galactosidase. AFD can involve various organs and lead to a series of clinical abnormalities. Left ventricular hypertrophy in middle-aged men is one of its life threatening complications. It was shown that pending the absence of myocardial replacement fibrosis, substitution therapy could improve myocardial morphology and function as well as exercise capacity. Today,...

Combined Fluorocholine Positron Emission Tomography and Magnetic Resonance Imaging (FCH-PET/MRI) in Curative Treatment of a Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is the fifth most common cancer in terms of incidence and the second in terms of mortality. At an early stage, which is based on a low number and size of liver nodules and the absence of extra-hepatic locations (Milan criteria), a curative treatment can be performed, i.e. liver transplantation, surgical resection, or thermo-ablation. These treatments can lead to severe complications, so patients benefiting from them must be carefully selected. The...

Brain Sleep Deprivation MRI Effects (BEDTIME)

The primary purpose of this study is to explore the underlying mechanisms that link sleep to Alzheimer's disease (AD), with special focus on the clearance of metabolites in the extracellular space of the brain during sleep. Subjects will wear an actigraph for 1 week to determine regular daytime activity and sleep patterns. Subjects will then undergo partial sleep deprivation followed by 4 hours of in-lab nocturnal polysomnography (NPSG). Participants will be be asked to stay aw...

The Possible Effect Of Amniotic Fluid pH On Neonatal Morbidities In Maternal Inflammation/Infection Associated Pregnancies

Amniotic fluid (AF) pH can be affected by the maternal and/or fetal conditions such as PPROM, prematurity or fetal distress. It is known that fetal urine is the major content of AF since 20th gestational week. Besides fetal alveolar fluid (FAF), gastrointestinal tract, umbilical cord and fetal side of placenta are important sources for AF. Bombesin-like peptides, 8-hydroxydeoxyguanosine in fetal urine and leukotriene E(4), lecithin, sphingomyelin, lamellar body in FAF are molec...

Coronary CT Angiography Using a Novel 3rd Generation Dual-Source CT System

Coronary CT angiography is used to examine the coronary arteries in a non-invasive way when a patient is suspected of having coronary artery disease. The test, however, requires relatively high levels of radiation, which have been linked to DNA damage and cancer, and the use of contrast material, which can affect kidney function. The SOMATOM Force, a new third-generation CT scanner manufactured by Siemens, was recently installed at MUSC and holds the potential to obtain quality...
