Purpose: Water freely diffuses across cell membranes, making it suitable for measuring absolute tissue perfusion. In this study, we introduce an imaging method for conducting coronary artery angiography and quantifying myocardial perfusion across the

ABSTRACT Shigellosis caused by Shigella is one of the most important foodborne illnesses in global health, but little is known about the metabolic cross talk between this bacterial pathogen and its host cells during the different stages of the infect

Hyperpolarized metabolic contrast agents for magnetic resonance imaging can provide non-invasive and realtime information on tissue specific aberrant metabolism, but producing and handling them is highly demanding because of their short lifetime. Her

Metabolic differences among and within tumors can be an important determinant in cancer treatment outcome. However, methods for determining these differences non-invasively in vivo is lacking. Using pancreatic ductal adenocarcinoma as a model, we dem

Purpose There is a limit to the maximum achievable preamplifier decoupling. In many cases, this level is not enough. To overcome this limit, the preamplifier noise figure can be compromised for further decoupling increase. This is useful in flexible

Cryogenically cooled magnetic resonance imaging (MRI) coils demonstrate extremely high Q -factors, leading to a very narrow bandwidth. This bandwidth can be increased in a controlled manner using a preamplifier decoupling. In this letter, an MRI coil
