[Experimental Methods and Result Analysis of a Variety of Spectral Reflectance Properties of the Thin Oil Film].

In order to analysis the oil spill situation based on the obtained data in airborne aerial work, it's needed to get the spectral reflectance characteristics of the oil film of different oils and thickness as support and to select the appropriate operating band. An experiment is set up to measure the reflectance spectroscopy from ultraviolet to near-infrared for the film of five target samples, which means petrol, diesel, lubricating oil, kerosene and fossil, using spectral measurement device. The result is compared with the reflectance spectra of water in the same experimental environment, which shows that the spectral reflection characteristics of the oil film are related to the thickness and the type of the oil film.

[Study on in-orbit Vis/SWIR relative calibration monitoring system with high stability].

The present paper studied the in-orbit relative calibration monitoring system with high stability for onboard remote sensing calibration. The realizing principle and the critical technologies are described in detail. The calibration detector assembly with high stability was developed based on both visual (Vis) and shortwave infrared (SWIR) trap structure.

Neovascularization in the carotid atherosclerotic plaque is not associated with inflammatory cell aggregation.

Background: Monocytes and macrophages in atherosclerotic plaque lead to plaque instability. The aim of the study was to determine if plaque neovascularization led to inflammation.

Methods: Patients were consecutively enrolled if their carotid intimal media thickness was > 2 mm, as revealed by duplex ultrasound.

Comparison of diffusion-weighted MRI with 18F-fluorodeoxyglucose-positron emission tomography/CT and electroencephalography in sporadic Creutzfeldt-Jakob disease.

18F-fluorodeoxyglucose-positron emission tomography/CT (18F-FDG PET/CT) scanning may be a useful tool for early diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD), as it may reveal lowered cellular glucose transport and metabolism in the cortex, cerebellum and basal ganglia. The aim of the present study was to compare the findings from PET/CT, MRI and electroencephalography (EEG) for patients with sCJD, to explore whether typical sites or reliable patterns of regional metabolic change could be found and to evaluate the results of diagnostic imaging in the light of clinical symptomatology. Five patients with biopsy-confirmed sCJD and nine with probable sCJD (aged 36-68 years) were evaluated using PET/CT, diffusion-weighted (DW)-MRI and EEG.

[Research on the ultraviolet reflectivity characteristic of simulative targets of oil spill on the ocean].

The authors set up an experiment instrument to measure the ultraviolet (UV) characteristic of oil spill simulation targets for the marine oil spill. After selecting appropriate conditions for experiments, the authors tested UV reflective spectrum of four simulation targets for oil spill (gasoline, kerosene, diesel fuel, lubricating oil). The authors calculated the UV absolute spectrum reflectivity of all testing targets from the standard white board as reference, whose UV reflectivity was given.

[Value of carbon-11 choline positron emission tomography in patients with pulmonary abnormalities].

Objective: To assess the value of carbon-11 choline (CH) positron emission tomography (PET) in patients with pulmonary nodules.

Methods: From September 2002 to December 2004, 39 patients with pulmonary nodules were imaged with CH-PET. CH-PET data was analyzed by visual method and semiquantitative method.

[Fluorine-18 fluorodeoxyglucose uptake in patients with benign pulmonary nodules].

Objective: To assess the features of fluorine-18 fluorodeoxyglucose (FDG) uptake in patients with benign pulmonary nodules.

Methods: From October 1998 to July 2004, 47 patients with benign pulmonary nodules were imaged with FDG-positron emission tomography (PET). Diagnoses were confirmed by surgery.

[Value of fluorine-18 fluorode oxyglucose-positron emission tomography in patients with small cell lung cancer].

Objective: To investigate the value of fluorine-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET) imaging in patients with small cell lung cancer.

Methods: From February 2000 to July 2003, 17 patients with small cell lung cancer were imaged with FDG-PET. FDG-PET scans were analyzed by visual method.
