Multi-slice spiral CT can accurately detect Ghostine et al in the left bundle branch block of coronary artery disease in Marie Lannelongue Hospital, France. Multi-slice spiral CT (MSCT) can be used in patients with left bundle branch block (LBBB). Detecting coronary artery disease (CAD). (J Am Coll Cardiol 2006, 48: 1929)
Ghostine said that, to their knowledge, this was the first study comparing LBBB patients with sinus heart rate patients with 64-slice CT and conventional coronary angiography. Ghostine and colleagues noted that LBBB is often associated with CAD, and identifying patients with chronic CAD in patients with LBBB is important for risk stratification and treatment management.
A total of 66 patients with complete left bundle branch block were enrolled in the study. The researchers used 64-slice CT to detect the presence or absence of CAD in these patients and compared them with conventional coronary angiography to determine the diagnostic accuracy of 64-slice CT. Evaluation.
The results showed that MSCT correctly indicated that 35/37 patients (95%) had no significant coronary stenosis, and correctly suggested that 28/29 patients (97%) had significant coronary stenosis. MSCT correctly indicated the presence of multiple lesions in all 15 patients. Among 94 stenotic lesions detected by conventional coronary angiography, MSCT can accurately detect 68 of them (72%).
In the patient-based analysis, the overall accuracy of MSCT was 95%, while in lesion analysis, the overall accuracy was 97%. MSCT was less sensitive to detection of left circumflex and right coronary lesions, 59% and 52%, respectively.
Research suggests that using MSCT to detect CAD can provide adequate diagnostic and prognostic information, reduce unnecessary imaging studies, and reduce radiation exposure in patients. —— Information from: Meditech Medical Network
Dye intermediates, also referred to as intermediates, refer to various aromatic derivatives used in the production of dyes and organic pigments. They are derived from benzene, toluene, naphthalene, anthracene and other aromatic hydrocarbons from coal chemical and petrochemical industries through a series of organic synthesis unit processes. With the development of chemical industry, the application range of dye intermediates has been extended to pharmaceutical industry, pesticide industry, propellant and explosive industry, information recording materials industry, as well as auxiliaries, surfactants, spices, plastics, synthetic fibers and other production sectors. There are many kinds of dye intermediates, and hundreds of them are more important. The most important early dye intermediates, such as nitrobenzene, aniline, phenol, chlorobenzene and phthalic anhydride, have been developed into important basic Organic Intermediates because of their wide use and large dosage. The annual output in the world is more than one million tons. The most important dye intermediates are o-nitrochlorobenzene, p-nitrochlorobenzene, o-nitrotoluene, p-nitrotoluene, 2-naphthol, anthraquinone, 1-aminoanthraquinone and so on. Starting from the above intermediates and through a series of organic synthesis unit processes, various intermediates with complex structures can be prepared.
Dye intermediates mainly include benzene intermediates, toluene intermediates, naphthalene intermediates and anthraquinone intermediates, in addition, there are some heterocyclic intermediates. The main reaction processes of intermediate in production are nitration, sulfonation, halogenation, reduction, amination, hydrolysis, oxidation, condensation and so on. The synthesis of a complex intermediate often takes many unit processes, sometimes using different basic materials and different synthetic routes.
