case presentation we present a case with a typical picture of myocarditis but normal echocardiographic findings, the diagnosis of which was confirmed by cardiac mri. discussion in particular, cardiac mri data are useful in borderline cases or in the presence of discrepancy between clinical picture and echocardiographic results. introduction the diagnosis of myocarditis based on a spectrum of fi...

levamisole is an anthelmintic agent and also immunostimulant drug which is used to treat colorectal cancer. the present study aimed to show accidental consumption of levamisole alone induced multifocal inflammatory leukoencephalopathy. a 53-year-old male was admitted to the neurology department of farabi hospital (kermanshah, iran) with walking inability and recognition disorder. following clin...

We studied the effect of focal cerebral ischemia on the "state" of brain water using proton nuclear magnetic resonance imaging. Focal cerebral ischemia was induced in five halothane-anesthetized rats via tandem occlusion of the left common carotid artery and the left middle cerebral artery. The proton transverse relaxation time, the proton density, and the water diffusion coefficient were measu...

Measurements of the proton spin-lattice relaxation time, Tx , in polycrystalline NH4Re04 have shown that mechanical sample rotation in the static magnetic field reduces 2\ for proton magnetic resonance frequencies within the range 30 — 42 MHz. The rotation induced proton spin-lattice relaxation times, ?Y, were measured at different Larmor frequencies, sample rotation frequencies, and temperatur...

PURPOSE Histological grading is currently one of the best predictors of tumor behavior and outcome in soft tissue sarcoma. However, occasionally there is significant disagreement even among expert pathologists. An alternative method that gives more reliable and non-subjective diagnostic information is needed. The potential use of proton magnetic resonance spectroscopy in combination with an app...

Surgery is a safe and effective treatment for drug-resistant temporal lobe epilepsy (TLE). However, bilateral electroencephalographic (EEG) abnormalities are frequently present, making presurgical lateralization difficult. New magnetic resonance (MR) techniques can help; proton magnetic resonance spectroscopic imaging (MRSI) can detect and quantify focal neuronal damage or dysfunction based on ...

OBJECTIVES To seek cerebral metabolite abnormalities in patients with myotonic dystrophy and to determine whether the degree of cerebral abnormalities (measured by proton magnetic resonance spectroscopy) correlates with severity of the genetic defect (measured by trinucleotide repeats). DESIGN Fourteen patients with myotonic dystrophy were compared with 24 healthy control subjects. SETTING ...

Cultured acute lymphoblastic leukemic cells give a well-resolved proton nuclear magnetic resonance spectrum characteristic of isolated plasma membranes. We demonstrate that the signals, in the spectrum of whole cells, arise predominantly from the plasma membrane and that cells transformed by pokeweed mitogen have membranes which are significantly less rigid than are normal human peripheral bloo...
