PURPOSE To compare the ability of qualitative fludeoxyglucose F 18 positron emission tomography (QPET), qualitative MR imaging (QMR), and quantitative MR imaging with hippocampal formation volumetric assessment (HV MR) to lateralize the seizure focus in patients with temporal lobe epilepsy. METHODS Sixteen consecutive patients undergoing presurgical examination for temporal lobe seizures had ...

Liver malformations including lobe and segmental abnormalities are rare. We report a 65-year-old lady with complaints of breathlessness and fullness after meals for two months. Investigations revealed a diaphragmatic hernia on the right side with a bifid liver; the right lobe of the liver was among the hernia contents. The lady is asymptomatic after surgical repair.

A 75-year-old female underwent a High Resolution Computed Tomography (HRCT) scan for recurrent bronchitis and cough. HRCT images showed an anomalous supernumerary bronchus to the right upper lobe directly arising from the right side of distal trachea, corresponding to Tracheal Bronchus (TrB). TrB can cause recurrent right upper lobe pneumonia and special care is requiring during endotracheal in...

As a rule, both lobes of Fanaroff-Riley (FR) type-II radio sources are terminated with hotspots, but the 3C 328 galaxy is specimen an FR II-like object hotspot in only one lobe. A conceivable reason for such asymmetry that nucleus was temporarily inactive. There no energy transfer from it to during period quiescence, and so they began fade out. However, under assumption axis connecting two make...

Digital Signal Processing techniques for ground surveillance RADAR has been thoroughly investigated and optimized for an improved detection of target. Using the established techniques like Pulse compression, Fast Fourier Transform and Windowing, the present work optimizes the selection of pulse coding techniques, window type and different filters.The work proposes techniques to mitigate inheren...

This paper talks about a method of conception and design constraints on mm-wave reflectarrays. The developed tool allows us to plan quickly the behavior of large reflectarray (several tens of wavelength) according to parameters as illumination law or manufacturing tolerance with good agreement with measurements. An ultra-low side-lobe reflectarrays of 130 mm diameter is designed. The structure ...

Objectives—To assess patterns of postictal cerebral blood flow in the mesial temporal lobe by coregistration of postictal TcHMPAO SPECT with MRI in patients with confirmed mesial temporal lobe epilepsy. Methods—Ten postictal and interictal Tc-HMPAO SPECT scans were coregistered with MRI in 10 patients with confirmed mesial temporal lobe epilepsy. Volumetric tracings of the hippocampus and amygd...

Fractal array antennas are multiband arrays having ultra wide band and space filling facility. But Side lobe levels and large number of antenna elements are the major designing challenges of these arrays. In this paper, design and analysis of octagonal fractal array antenna is investigated with Morse-Thue fractal density tapering technique (MTFDT). Due to the proposed technique, a remarkable im...

Linear antenna array design is one of the most important electromagnetic optimization problems of current interest . In the antenna arrays the side lobe level is main problem which causes wastage of energy. This paper describes the application of a recently developed metaheuristic algorithm ,known as the Particle Swarm Optimization Gravitational Search Algorithm(PSOGSA) to optimize the spacing ...
