Positron emission tomography (PET) is an advanced nuclear medicine imaging technique that produces three-dimensional images of metabolic and physiological processes within the body. Unlike anatomical imaging (such as CT or MRI, which show structure), PET shows how tissues are functioning at a cellular level by detecting the radiation emitted by a radioactive tracer injected into … Read more
Pericardiostomy is a surgical procedure in which the pericardium (the membranous sac surrounding the heart) is incised and a drainage tube is inserted to allow continuous or intermittent drainage of fluid from the pericardial space. It is used when a significant accumulation of fluid (pericardial effusion) is causing symptoms or haemodynamic compromise, and when repeated … Read more
