Stress-rest dynamic-CT myocardial perfusion imaging in the management of myocardial bridging: A "one-stop shop" exam.

Unlabelled: Myocardial bridging (MB) is a congenital anomaly characterized by the intramyocardial coronary course that can cause coronary compression during systole leading to myocardial ischemia, often with the concomitant presence of endothelial dysfunction.Improvements in computed tomography (CT) technology have increased the burden of MB detection during coronary-CT (cCT) but their anatomical and functional assessment is often challenging. A stress-rest myocardial perfusion imaging (MPI) by single-photon emission CT (SPECT) is usually required to decide the correct patient management.

Ultra-low radiation dose and contrast volume CT protocol and TAVI-CT score for TAVI planning and outcome.

Objective: To investigate the feasibility of an ultra-low radiation dose and contrast volume protocol using third-generation dual-source (DS) CT for transcatheter aortic valve implantation (TAVI) planning with coronary artery disease (CAD) assessment, coronary artery calcium score (CACS) and aortic valve calcium score (AVCS) quantification and to evaluate their relationship with TAVI outcome.

Methods: In this retrospective study were selected 203 patients (131 males, 79.4 ± 5.

Arbuscular Mycorrhizal Fungi Increase Nutritional Quality of Soilless Grown Lettuce while Overcoming Low Phosphorus Supply.

Lettuce is widely used for its healthy properties, and it is of interest to increase them with minimal environmental impact. The purpose of this work was to evaluate the effect of the arbuscular mycorrhizal fungus (AMF) in lettuce plants ( L. cv.

Bayesian Sigmoid-Type Time Series Forecasting with Missing Data for Greenhouse Crops.

This paper follows an integrated approach of Internet of Things based sensing and machine learning for crop growth prediction in agriculture. A Dynamic Bayesian Network (DBN) relates crop growth associated measurement data to environmental control data via hidden states. The measurement data, having (non-linear) sigmoid-type dynamics, are instances of the two classes observed and missing, respectively.
