Association of leukoencephalopathy, cerebral calcifications, and cysts (LCC) is a rare disorder that was recently described. To our knowledge, only 2 reports, including 3 patients in each, have been published in the literature to date. Herein, we report a 19-year-old man with LCC who had neurological symptoms beginning in late adolescence. Clinically, he had rare convulsive seizures, slowly pro...

INTRODUCTION: recurrent disease after external beam radiotherapy is suspected after biochemical failure (rising PSA) and may be local, systemic, or both. Transrectal ultrasound guided biopsy is the standard of care for the detection of local recurrence, but is invasive and may miss tumors since only a small fraction of the gland is sampled. Although endorectal T2-weighted MR imaging has emerged...

Cardiac magnetic resonance imaging is considered the reference technique for characterizing myocardial tissue; for example, T2-weighted sequences make it possible to evaluate areas of edema or myocardial inflammation. However, traditional sequences have many limitations and provide only qualitative information. Moreover, traditional sequences depend on the reference to remote myocardium or skel...

Background Recent studies suggest that quantitative myocardial T1 mapping allows assessment of focal and diffuse fibrosis in the myocardium [1]. Quantitative T2 mapping has also been proposed to overcome challenges associated with T2 weighted imaging [2]. These maps are traditionally acquired with different sequences, necessitating image registration to evaluate them jointly. A sequence that ca...

We report on a 55-year-old man with alcoholic liver cirrhosis who presented with status epilepticus. Laboratory analysis showed markedly elevated blood ammonia. Brain magnetic resonance imaging (MRI) showed widespread cortical signal changes with restricted diffusion, involving both temporo-fronto-parietal cortex, while the perirolandic regions and occipital cortex were uniquely spared. A follo...

In rare cases restricted sensory deficits along the somatotopic topography of the spinothalamic tract can develop from a lateral medullary infarction. To our knowledge, isolated dermatomal sensory deficit as a single manifestation of a lateral medullary infarction has not been reported previously. A 58-year-old man presenting with sudden left-sided paresthesia complained of sensory deficit of p...

OBJECTIVE To emphasize the contribution of superparamagnetic iron oxide (SPIO) contrast agent in the diagnosis of the splenic hamartoma. CLINICAL PRESENTATION AND INTERVENTION A 63-year-old female was admitted to our hospital with diffuse abdominal pain. An ultrasound examination revealed a 5 × 4 cm solid lesion in the spleen. Dynamic gadolinium-enhanced magnetic resonance imaging (MRI) of th...

the incidence of multiple myeloma (mm) affecting the jaws is 30% and on rare occasions the oral involvement can be the first indication of the disease. authors report a case of mm in a 40-yearold woman who presented with a multilocular radiolucent lesion in the left mandible initially mistaken as an ameloblastoma. conventional radiographs revealed a multilocular lesion on the molar region. comp...

Diffuse optical imaging is a functional medical imaging modality which takes advantage of the relatively low attenuation of near-infrared light to probe the internal optical properties of tissue. The optical properties are affected by parameters related to physiology such as the concentrations of oxyand deoxyhemoglobin. Instrumentation that is used for optical imaging is generally able to measu...

A new propeller EPI pulse sequence with reduced sensitivity to field inhomogeneities is proposed. Image artifacts such as blurring due to Nyquist ghosting and susceptibility gradients are investigated and compared with those obtained in previous propeller EPI studies. The proposed propeller EPI sequence uses a readout that is played out along the short axis of the propeller blade, orthogonal to...
