We obtain the parity invariant generating functional for the canonical transformation mapping the Liouville theory into a free scalar field and explain how it is related to the pseudoscalar transformation e-mail: [email protected] Present address: Department of Mathematical Sciences, University of Durham, UK 1 In this paper we consider the 2-dimensional Liouville theory, based on the Lagrangi...

Pseudo-aneurysm of internal maxillary artery, following a road traffic accident, is rare clinical scenario. The consequence pseudo-aneurysm may be spontaneous rupture the arterial wall, which eventually lead to life-threatening hemorrhage. We report case 20-year male who presented with recurrent epistaxis. CT scan was performed, revealed artery; this successfully treated by angioembolisation. S...

A 45-year-old female patient presented with severe abdominal pain and nausea for one day. Radiograph of the kidney, ureter, and bladder (KUB) revealed marked distension of the feces-filled bowel loop in the right lower abdomen. Contrast-enhanced computed tomography (CT) findings revealed a short segmental wall thickening and luminal narrowing at the hepatic flexure of the colon, marked distensi...

Differentiation between tumours and pseudo-tumours is essential for planning adequate treatment and for estimating outcome and future prognosis. Per definition, tumour and pseudo-tumours are lesions that look alike on ultrasound (US), computer tomography (CT) or magnetic resonance imaging (MRI) studies. Misinterpretation may lead to a significant delay of adequate treatment for malignant tumour...

A 75-year-old woman presented with a sudden onset of blurred vision and abnormal neck posture. Neurologic examination showed pseudo-retrocollis (RC) (figure 1), reduced by closing her eyes, and a right side visual field defect. CT scan showed a left temporo-occipital ischemic lesion and visual field campimetry revealed right superior homonymous quadrantanopia (sHQ) (figure 2, A and B). Figure 1...

Radiotherapy planning and attenuation correction of PET images require simulation of radiation transport. The necessary physical properties are typically derived from computed tomography (CT) images, but in some cases, including stereotactic neurosurgery and combined PET/MR imaging, only magnetic resonance (MR) images are available. With these applications in mind, we describe how a realistic, ...
