PET/MR imaging for chest diseases review of initial studies on pulmonary nodules and lung cancers
No full textPET/MR imaging, a new hybrid modality, is thought to have great potential in oncologic imaging because it provides advantages of both PET, which allows functional imaging capability, and MR imaging, which allows high spatial resolution imaging without radiation exposure. Despite the inherent weakness of MR imaging in lung imaging, initial studies on lung cancer revealed that PET/MR imaging showed highly correlated standardized uptake values of lesions and equivalent performance in terms of lesion detection and staging compared with PET/computed tomography (CT). Thus, to affirm the actual clinical benefits of dedicated PET/MR imaging over PET/CT, prospective studies with more patients are warranted.N
The uplift principle for ordered trees
No full textAbstractIn this paper, we describe the uplift principle for ordered trees which lets us solve a variety of combinatorial problems in two simple steps. The first step is to find the appropriate generating function at the root of the tree, the second is to lift the result to an arbitrary vertex by multiplying by the leaf generating function. This paper, though self contained, is a companion piece to Cheon and Shapiro (2008) [2] though with many more possible applications. It also may be viewed as an invitation, via the symbolic method, to the authoritative 800 page book of Flajolet and Sedgewick (2009) [8]. Our examples, with one exception, are different from those in this excellent reference
