Retroperitoneal malignant mesenchymoma is a rare retroperitoneal neoplasm with poor prognosis. Here we present a patient with retroperitoneal malignant mesenchymoma. A 32year-old man presented with progressive painful swelling on his left lower leg, abdominal fullness and a palpable left abdominal mass. Imaging studies of abdomen included sonography, contrastenhanced computed tomography (CECT) ...

has emerged as a new noninvasive modality in the investigation of cardiovascular disease during the last decade. Cardiovascular magnetic resonance (CMR) has well-established imaging capabilities for the assessment of global and regional left ventricular (LV) function and mass. Its potential for the assessment of ischaemic heart disease is currently being explored in many centres. The main focus...

we present a case report of bupropion-induced diplopia in a 26-year-old woman who suffered from atypical depression. âfter four weeks of taking bupropion (225 mg per day) she complained of headaches, blurred vision, and diplopia. no neurological and ophthalmologic abnormal signs were found. her brain magnetic resonance imaging (mrï) and magnetic resonance venography (mrv) were normal as well. â...

in recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (mri), functional magnetic resonance imaging (fmri), positron emission tomography (pet), or single photon emission tomography (spect) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. in anxiety disorders, recent...

A recent quantum computing paper (G. S. Uhrig, Phys. Rev. Lett. 98, 100504 (2007)) analytically derived optimal pulse spacings for a multiple spin echo sequence designed to remove decoherence in a two-level system coupled to a bath. The spacings in what has been called a "Uhrig dynamic decoupling (UDD) sequence" differ dramatically from the conventional, equal pulse spacing of a Carr-Purcell-Me...

results a low adc value was associated with lymph node metastasis (p < 0.01) and with high ki-67 protein levels (p = 0.03). there were no significant differences in the adc values among the histological grade (p = 0.48), molecular subtype (p = 0.51), tumor size (p = 0.46), and p53 protein level (p = 0.62). conclusion the pre-operative use of the 3.0 tesla dwi could provide information about the...
