Central Glutathione Levels in Women With Late Life Depression: a Cross Sectional Pilot Feasibility Study

Female participants with an episode of late-life depression (LLD) and age-matched control participants with no history of mental disorder will attend a one hour Magnetic Resonance Imaging (MRI). A 3 Tesla MRI scanner will be used to measure levels of glutathione (GSH) in the brain via magnetic resonance spectroscopy (1H MRS).

Accuracy of 1.5 T Versus 3 T Magnetic Resonance Arterial Spin Labeling to Measure Renal Blood Flow

In this study, investigators want to compare the accuracy of two methods to measure renal perfusion by MRI spin labelling technique: the first measurement done with the 1.5 T MRI versus the second one obtained with the 3.0 T MRI (Siemens MRI device).

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...

Semi-automatic assessMent of Aortic Roots by Three-dimensional transoEsophageal echocaRdiography (SMARTER)

The progress in surgery of the aortic root and the evolution of transcatheter aortic valve replacement as an alternative to surgical treatment in selected patients have refocused the need for quantitative imaging of the aortic root during transcatheter aortic valve replacement and valve-sparing aortic root surgery. In this study, we aim to assess the ability of semi-automated quantitative modeling (eSie Valves, Autovalve prototype version, Siemens Medical Solutions, USA) of the...

Haemoglobin Measurement for Babies

In this prospective study different methods of haemoglobin measurement in term and preterm neonates are compared with the gold standard. Non-invasive haemoglobin measurement with the Radical-7® (SpHb, Masimo®), point-of-care haemoglobin-measurement (HcHb, HemoCue@, Radiometer), blood-gas-analysis (BGAHb,ABL800®, Radiometer) are compared with haemoglobin measurement by an automated hematology analyzer (labHb, Siemens Advia®).

Processing Integration in Neurological Patients Using fMRI

The main objective of the study is to explore and map brain areas involved in processing and perception in patients suffering from neurological pathologies and condition. The investigators hypothesize for example, that a change (compare to healthy subjects) in the perceptual maps and body representation could be detected and characterize in patients suffering from impairments of peripheral nerve conduction.

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...

FSH/LH Ratio as a Predictor of IVF Outcome in Young and Older Women

All women had normal uterine cavity determined by previous hysterosalpingography or hysteroscopy. Women with abnormally low Gn as hypothalamic hypogonadism , High LH as PCOS and women with abnormal endocrine functions as abnormal thyroid or adrenal functions were excluded. Any woman with ovarian cyst or azopermic male partner was also excluded. The patients were subjected to history taking, including age, duration, type and cause of infertility and medical history. Full examin...

PET/MRI in Patients With Suspected Prostate Cancer

This diagnostic clinical trial will be conducted according to a randomized, prospective, controlled, double-arm, single-centre design. The control will be implemented by comparing the PET/MRI results with the histopathological finding after radical prostatectomy (positive state), the assumed absence of a relevant prostate cancer focus if PET/MRI guided biopsy and standard biopsy are negative (negative state) and/or the detection of a biochemical tumor relapse (rising PSA after ...

Cone-beam CT Guided Microcoil Localization of Pulmonary Nodules During Video Assisted Thoracic Surgery(VATS)

The Guided Therapeutics (GTx) program at the University Health Network is a network of clinicians, scientists, and engineers focused on the development and translation of image-guided technologies focused on minimally-invasive, adaptive therapies. Technologies developed within the GTx program include a portable intra-operative cone-beam CT (in collaboration with Siemens) that has been evaluated in clinical trials for head and neck surgery. The intraoperative imaging has been in...

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...

Measurement of Cerebral Oxygen Extraction Fraction Using MRI Technique

All images in this study were acquired on a 1.5 T Sonata whole body scanner (Siemens Medical Inc., Erlangen, Germany) using 2D multi-echo gradient echo/spin echo sequence and 2D single-shot gradient echo-planar imaging sequence plus intravenous magnetic susceptibility contrast medium. The quantitative estimates and mapping of cerebral metabolic rate of oxygen utilization were calculated and plotted in all subjects.

Validation of the Siemens System Somatom Definition and Operating Software for Cardiac CT Studies

We are evaluating a new computer software package to help us acquire and interpret heart CT studies, which is the purpose of this research project. We plan to compare the acquiring and analysis of heart artery calcium scores and CT angiograms (scans of the heart arteries) with the new SYNGO Somaris/7 Cardiac software to our previous experience with the the existing Siemens software and the TeraRecon software (current software used in the Cardiovascular MR/CT lab). The main obje...

Development of New Software Capabilities for Use With Cardiovascular Magnetic Resonance Imaging

This Protocol is intended to facilitate development and testing of new cardiovascular MRI software capabilities by UC Davis Research Faculty, as well as to facilitate the evaluation of new software capabilities provided by GE and Siemens.

Siemens 3-D C-Arm CT of the Heart Chambers

The purpose of this study is to determine the optimal images of the heart structures which are used to guide AF ablation or BiVenticle and coronary vessels.

Serial BNP Testing for Heart Failure Management

The scope of the USE-BNP Trial is to investigate whether knowledge of BNP measurements, in conjunction with clinical assessment, in the outpatient setting can guide the management of therapy in patients with heart failure.

Radiation Dose From Computed Tomography Before and After Implementation of a High Pitch Dual Spiral Technique

The purpose of this study is to compare the radiation exposure of a variety of chest CT examinations performed on the current state of the art CT scanners (64 slice, dual source CT scanner) with the radiation exposure for identical chest CT examinations performed on the Siemens Flash CT scanner (high pitch dual source spiral technique).
