| Angiography |
Radiographic
technique to visualize the internal anatomy of the heart and blood vessels
after the injection of a contrast medium. |
| Audiology |
The
study of hearing |
|
 |
| Baroreceptor |
One
of the pressure-sensitive nerve endings in the walls of the atria of the
heart, the vena cava, the aortic arch and the carotid sinus. They stimulate
central reflex mechanisms that allow pysiological adjustment and adaptation
to changes in blood pressure via vasodilatation or vascoconstriction. |
|
 |
| Capnometry |
The
measurement of carbon dioxide in a volume of gas. |
| CAT |
Computed
(Computerized) Axial Tomography (See CT) |
| CT |
Computed
Tomography. A radiographic technique that produces detailed cross sectional
images of tissue structures. |
|
 |
| ECG |
Electocardiogram.
A recording of the electrical activity of the myocardium which allows diagnosis
of cardiac abnormalities. |
| Echocardiography |
A
diagnostic procedure used to study the structure and motion of the heart. |
| EEG |
Electroencephalogram |
| EIT |
Electrical
Impedance Tomography. EIT uses electric fields to image body parts, based
on the fact that sub-regions of the tissue differ in conductivity. The path
of the imaging beam is a function of the conductivity of the tissue, and
in order to establish a quantitative basis for the image the conductivity
distribution of the region has to be reconstructed. |
| EMG |
Electromyogram.
A recording of the electrical activity in skeletal muscle. |
|
 |
| HPS |
His-Purkinje
System. The hearts specialised electrical conduction system, the signals
from which are measured using high resolution electrocardiograms. |
|
 |
| ICU |
Intensive
care unit |
|
 |
| Laser
Doppler Flowmetry |
Laser
Doppler Flowmetry is a non-invasive technique that has been used to study
the flow of cutaneous or peripheral blood flow. MORE |
|
 |
| MEG |
Magnetoencephalogram.
|
| MRI |
Magnetic
Resonance Imaging. MORE |
| MUGA
Scan |
Multi-gated
blood-pool imaging. Used to measure heart pump function. |
|
 |
| NADH |
Nicotinamide
Adenine Dinucleotide, reduced. A substance synthesized from niacin that
is contained in all living cells. |
| Neonatal |
The
period covering the first 28 days after birth. |
| NIRS |
Near
Infra-red Spectroscopy |
|
 |
| Oximeter |
Device
used to measure oxyhaemoglobin |
| Oxyhaemoglobin |
The
product of combining oxygen with haemoglobin. |
|
 |
| PET |
Positron
Emission Tomography MORE |
| Physiology |
The
study of the physical and chemical processes involved in the functioning
of the human body. |
| Plethysmography
|
The
measurement and recording of changes in the sizes and volumes of organs
and extremities by measuring changes in blood volume. |
|
 |
| Radionuclide
Imaging |
A
method of imaging the functional anatomy of the body, following administration
of a radiopharmaceutical, using gamma camera. |
|
 |
|
| SAECG |
Signal
Averaged Electrocardiogram. A specialized ECG which may identify areas of
delayed electrical conduction of the heart. |
| Surface
Fluorimetry |
The
measurement of fluorescence emitted by compounds when exposed to ultraviolet
or other intense radiant energy. |
| SQUID |
Superconducting Quantum Interference Device. |
|
 |
| Tomography |
An
X-ray technique that produces a detailed cross-section of tissue structure
at a predetermined depth. |
| Transcranial
Doppler Sonography |
An
ultrasonic technique that allows real- time continuous measurements of blood
flow velocity in major intracranial vessels within the circle of Willis.
It is used to monitor cerebral circulation under cardiac, vascular and neurological
surgeries and to detect cerebral embolisms. |
|
 |
|
| Ultrasound |
A
technique for imaging internal structures of the body by measuring and recording
the reflection of pulsed or continuous high-frequency sound waves. |
|
 |
| Vasoconstriction |
The
narrowing of any blood vessel. |
| Vasodilatation |
Widening
or distention of blood vessels |
