It involves two main types of thinking: divergent, in which one tries to generate a diverse assortment of possible alternative solutions to a problem, and convergent, in which one tries to narrow down multiple possibilities to find a single, best answer to a problem.
The vessel features are a high aspect ratio and a rather narrow multiple-impeller draft tube, through which the gas phase is ingested and led down to the vessel bottom, where it is finely dispersed into the liquid rising in the annular portion of the vessel.
CAD was defined as at least one major epicardial vessel with ≥50% stenosis, assessed by quantitative coronary angiography, and evaluated independently by two operators, who made visual estimation of luminal narrowing in multiple segments based on a modified form of the AHA/ACC classification of the coronary tree.
Double contrast radiological examination may reveal a variable segment of oesophageal narrowing with multiple discrete ulcers or a distinctive granular appearance of the mucosa within a known irradiated volume, suggesting the diagnosis of radiation oesophagitis [ 19], but a quantitative evaluation of altered oesophageal transit cannot be assessed.
I liked role-playing Stephanie Patrick's debut seven years ago in Mark Burnell's The Rhythm Section, but as the series developed and he narrowed down her multiple personalities, I was less convinced.
The technique is based on the unproven theory that narrowed veins cause multiple sclerosis by stopping blood from draining out of the brain properly, which is thought to damage nerves and the fatty sheath, myelin, that insulates them.
DSA showed multiple segments of narrowing in vessel calibre.
Digital subtraction angiography (DSA) showed multiple segments of narrowing in vessel calibre (Fig. 2a, c).
Digital subtraction angiography (DSA) showed multiple segments of narrowing in vessel calibre.
Multiple segments of narrowing in vessel calibre in basilar artery (c) were also improved after therapy (d).
