Transesophageal echocardiography (TEEC) is a diagnostic procedure that involves feeding a small ultrasound device into a patient's esophagus to evaluate heart function. Since the esophagus is very close to the heart (left atrium), there is less noise-distortion compared to traditional echocardiography and higher-resolution images can be obtained.Transesophageal echocardiography may be used to diagnose heart conditions, assess the overall function of the heart, or evaluate abnormalities of the left atrium.Contraindications include previous esophageal surgery, swallowing problems, severe hiatal hernia, previous chest radiation, severe bleeding problems, and severe esophageal ulcers.…

The history ofneuroimaging, began in the early 1900s with a technique calledpneumoencephalography. This process involved draining the cerebrospinalfluid from around the brain and replacing it with air, altering therelative density of the brain and its surroundings, to cause it to showup better on an x-ray. It was considered to be incredibly unsafe forpatients. A form of magnetic resonance imaging (MRI) and computedtomography (CT) were developed in the 1970s and 1980s. The new MRI andCT technologies were considerably less harmful and are explained ingreater detail below. Next came SPECT and PET scans, which allowedscientists to map brain function because, unlike MRI and CT, these scanscould create more than just static images of the brain's structure.Learning from MRI, PET and SPECT scanning, scientists were able todevelop functional MRI (fMRI) with abilities that opened the door todirect observation of cognitive activities.…

Itis derived from ventriculography, an earlier and more primitive onewhere the air is injected through holes drilled in the skull. Theprocedure was introduced in 1919 by the American neurosurgeon WalterDandy. Pneumoencephalography was performed extensively throughout thelate 20th century, but it was extremely painful and, as researcherswould later discover, very dangerous. The test was generally not welltolerated by patients. Headaches and severe vomiting were common sideeffects. Replacement of the spinal fluid was by natural generation andtherefore required recovery for as long as 2-3 months before normalmovement was restored.…
