The aim of this review was to discuss the current literature regarding the utility of noninvasive imaging in diagnosis and management of stable coronary artery disease (CAD) including recent data from large randomized trials assessing diagnosis and prognosis. Current guidelines recommend revascularization in patients with refractory angina and in those with potential prognostic benefit. Appropr...
BACKGROUND The discovery of cell free fetal DNA (cff-DNA) in maternal plasma has brought new insight for noninvasive prenatal diagnosis. Combining with the rapidly developed massively parallel sequencing technology, noninvasive prenatal detection of chromosome aneuploidy and single base variation has been successfully validated. However, few studies discussed the possibility of noninvasive path...
Coronary artery disease (CAD) causes significant morbidity and mortality. Accurate noninvasive evaluation is important to facilitate appropriate diagnosis treatment. The ubiquitous nature of CAD requires all practitioners, regardless their specialty, be familiar with diagnostic modalities. This article reviews currently available tests, including specific features, prognostic value, strengths, ...
Accurate diagnosis of acute rejection remains a formidable challenge in organ transplantation. The current gold standard diagnostic test for acute rejection is histological examination of the transplanted organ. However, biopsy procedures are invasive and complications occur. Furthermore, sampling errors may bias the histological diagnosis. Not uncommonly, empiric anti-rejection therapy has to ...
case presentation we present a case with a typical picture of myocarditis but normal echocardiographic findings, the diagnosis of which was confirmed by cardiac mri. discussion in particular, cardiac mri data are useful in borderline cases or in the presence of discrepancy between clinical picture and echocardiographic results. introduction the diagnosis of myocarditis based on a spectrum of fi...
From the prospective and outcome-based studies that have been carried out in the past few years, the following conclusions regarding the diagnostic evaluation of patients with suspected PE can be made: 1. A normal V/Q scan interpretation excludes the diagnosis of clinically significant PE. 2. Patients with a very-low- or low-probability V/Q scan interpretation and a low clinical likelihood of P...
Noninvasive diagnosis of internal traits in fruit crops is a high unmet need; however it generally requires time, costs, and special methods or facilities. Recent progress deep neural network (or learning) techniques would allow easy, but highly accurate with single RGB images, the latest applications enable visualization “the reasons for each diagnosis” by backpropagation networks. Here, we pr...
