| amphoric resonance | A percussion sound, like that produced by striking a large empty bottle, obtained by percussing over a pulmonary cavity. Synonym: cavernous resonance. (05 Mar 2000) |
|---|---|
| bandbox resonance | A peculiar, partly tympanitic, partly vesicular sound, obtained on percussion in cases of pulmonary emphysema. Synonym: bandbox resonance, wooden resonance. (05 Mar 2000) |
| bellmetal resonance | In cases of a large pulmonary cavity or of pneumothorax, a clear metallic sound obtained by striking a coin, held against the chest, by another coin, or by flicking the chest wall with one's fingernail; the sound is heard on auscultating the chest wall on the same side anteroposteriorly. Synonym: anvil sound, bell sound, coin test. (05 Mar 2000) |
| magnetic resonance angiography | Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in cerebral angiography as well as for studies of other vascular structures. (12 Dec 1998) |
| Magnetic Resonance Imaging | A special imaging technique used to image internal stuctures of the body, particularly the soft tissues. An MRI image is often superior to a normal X-ray image. It uses the influence of a large magnet to polarize hydrogen atoms in the tissues and then monitors the summation of the spinning energies within living cells. Images are very clear and are particularly good for soft tissue, brain and spinal cord, joints and abdomen. These scans may be used for detecting some cancers or for following their progress. Acronym: MRI (11 Nov 1997) |
| magnetic resonance imaging, cine | A type of imaging technique used primarily in the field of cardiology. By coordinating the fast gradient-echo mri sequence with retrospective ecg-gating, numerous short time frames evenly spaced in the cardiac cycle are produced. These images are laced together in a cinematic display so that wall motion of the ventricles, valve motion, and blood flow patterns in the heart and great vessels can be visualised. (12 Dec 1998) |

| magnetic resonance spectroscopy | Detection and measurement of the resonant spectra of molecular species in a tissue or sample. (05 Mar 2000) |
| vesicular resonance | The sound obtained on percussing over the normal lungs. (05 Mar 2000) |
| vesiculotympanitic resonance | A peculiar, partly tympanitic, partly vesicular sound, obtained on percussion in cases of pulmonary emphysema. Synonym: bandbox resonance, wooden resonance. (05 Mar 2000) |
| cavernous resonance | A percussion sound, like that produced by striking a large empty bottle, obtained by percussing over a pulmonary cavity. Synonym: cavernous resonance. (05 Mar 2000) |
| vocal resonance | The voice sounds as heard on auscultation of the chest. (05 Mar 2000) |
| resonance | 1. The act of resounding; the quality or state of being resonant. 2. <physics> A prolongation or increase of any sound, eithar by reflection, as in a cavern or apartment the walls of which are not distant enough to return a distinct echo, or by the production of vibrations in other bodies, as a sounding-board, or the bodies of musical instruments. 3. <chest medicine, physiology> Pulmonary resonance, the sound transmitted to the ear when auscultation is made while the patient is speaking. Origin: Cf. F. Resonance, L. Resonantia an echo. Source: Websters Dictionary (01 Mar 1998) |
| resonance energy transfer | <technique> Transfer of energy from one fluorochrome to another. The emission wavelength of the fluorochrome excited by the incident light must approximately match the excitation wavelength of the second fluorochrome. If light at the second emission wavelength is detected, it implies that the two fluorochromes were physically within a few nanometres. Used as a technique to probe protein or cell interactions. (25 Jun 1999) |
| resonance theory of hearing | That the basilar membrane of the cochlea acts as a resonating structure, recording low tones from its apical turns and high tones from its basal turns. Synonym: Helmholtz theory of hearing. (05 Mar 2000) |
