Abstract Positron emission tomography (PET) is a widely used imaging modality in nuclear medicine for variety of applications. Amongst the methods quantifying and interpretation PET images, standardized uptake value (SUV) widely-adopted semi-quantitative tool that supplements visual understanding with quantitative information. SUV both clinical preclinical practices to report status various nor...

PURPOSE To compare the reproducibility of semi-automated vessel analysis software to manual measurement of carotid artery stenosis on computed tomography angiography (CTA). METHODS Two observers separately analyzed 81 carotid artery CTAs using semi-automated vessel analysis software according to a blinded protocol. The software measured the narrowest stenosis in millimeters (mm), distal inter...

environmental impact assessment (eia) has led to the dominance of planners on the natural environment of the regions, providing the possibility of continuously monitoring and controlling the status quo by management staff. in this regard, a new semi-quantitative model is presented for the eia of the eastern alborz coal mining complex using the matrix method, and determining the corresponding im...

coriandrum sativum l. is one of the most important plants compared to the other herbs and medicinal plants as a planted covered area in kermanshah province. for a suitable irrigation management programming, the awareness of crop coefficient and water requirement in different plant stages is essential. the ratio of actual evapotranspiration to reference crop evapotranspiration is defined as crop...

A fully automated and highly sensitive method with a semi-microcolumn liquid chromatography system for the determination of rat plasma catecholamines (CAs) was developed. Automated on-line extraction of CAs in diluted plasma using a precolumn packed with strong acidic cation exchange resin was coupled with separation of CAs on a semi-microcolumn (250 x 1.5 mm id). fluorogenic derivatization wit...
