…Definition and Clinical Purpose Myocardial perfusion imaging (MPI) with single photon emission computed tomography (SPECT) or positron emission tomography (PET) is a radionuclide based method…

…repertoire of available methods includes echocardiography, cardiovascular magnetic resonance (CMR), cardiac computed tomography (CT), single photon emission computed tomography (SPECT), positron emission computed tomography (PET…

Procedurer The insertion itself is rarely the difficult part — it is the confirmation of the position that determines whether the tube is safe. A misplaced…

…that ensures that no other sound waves affect the transducer. The crystals are supported by a backing layer that suppresses the vibrations of the crystals…

Procedurer What determines the outcome of an emergency intubation is rarely the laryngoscopy itself but what was done before it: how well the patient was…

…full range of LVEF, and echocardiographic measurement is subject to meaningful variability. HFmrEF may therefore represent several clinically distinct trajectories: A patient whose LVEF has…
