BACKGROUND AND OBJECTIVES Carbon monoxide is a toxic gas for humans and is still a silent killer in both developed and developing countries. The aim of this case series was to evaluate early radiological images as a predictor of subsequent neuropsychological sequelae, following carbon monoxide poisoning. CASE 1 After carbon monoxide exposure, early computed tomography scans and magnetic reson...

BACKGROUND Cardiac allograft rejection and vasculopathy are the main factors limiting long-term survival after heart transplantation.In this pilot study we investigated whether non-invasive methods are beneficial to detect cardiac allograft rejection (Grade 03 R) and cardiac allograft vasculopathy. Thus we compared multi-slice computed tomography and magnetic resonance imaging with invasive met...

We report time-resolved optical flux and circular polarization spectroscopy of the magnetic DA white dwarf HE 1045−0908 obtained with FORS1 at the ESO VLT. Considering published results, we estimate a likely rotational period of Prot 2.7 h, but cannot exclude values as high as about 9 h. Our detailed Zeeman tomographic analysis reveals a field structure which is dominated by a quadrupole and co...

Noninvasive imaging methods for medical diagnosis and biological investigations, have evolved from qualitative radiological techniques to quantitative methods of measuring biochemical and physiological processes in human body. In particular, new developments in emission tomography, nuclear magnetic resonance imaging, and in vivo spectroscopy offer new horizons for medical research and clinical ...

The introduction of tomographic imaging revolutionized the way we look at medical images. Compared to X-ray projective image, Computer Tomography (CT) offers the possibility of analyzing anatomical structures on a three-dimensional, slice-to-slice approach. On the other hand, limitations of CT consist of poor soft tissue contrast and ionizing radiation [1], while the advantages are distortion-f...

The magneto-mechanical effect is exploited as a means of producing background-free contrast in optical coherence tomography (OCT). Contrast agents consisting of iron-oxide particles and protein microspheres encapsulating colloidal iron-oxide have a sufficiently high magnetic susceptibility to be detected by modulation of a magnetic field gradient using a small solenoid coil. The externally-appl...

we report an unusual case of a young male with cerebellar hemangioblastoma treated previously for medullary carcinoma of thyroid, whose pet/ct scans revealed a constellation of findings that suggested the rare von hippel lindau syndrome. the diagnosis was clinched by confirming the findings on whole body contrast enhanced computed tomography (cect) and contrast enhanced magnetic resonance imagi...

Magnetic resonance-electrical impedance tomography (MR-EIT) is a conductivity imaging method based on injecting currents into the object. In this study, a new MR-EIT method, whereby currents are induced inside the object by using external coils, is proposed. This new method is called induced current magnetic resonance-electrical impedance tomography. In induced current MR-EIT surface electrodes...

Herein, we report a 66 year old woman who was diagnosed to have intrabiliary rupture of liver hydatid cyst with demonstrative computed tomography, magnetic resonance imaging, and magnetic resonance cholangiopancreatography findings, with a review of the literature.
