| 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.

| wooden resonance | A peculiar, partly tympanitic, partly vesicular sound, obtained on percussion in cases of pulmonary emphysema. Synonym: bandbox resonance, wooden resonance. (05 Mar 2000) |
| cracked-pot resonance | A peculiar sound, resembling that heard on striking a cracked pot, elicited on percussing over a pulmonary cavity that commmunicates with a bronchial tube, when the patient's mouth is open. Synonym: cracked-pot sound. (05 Mar 2000) |
| cyclotron resonance | <radiobiology> Charged particles in a magnetic field resonate with (and absorb energy from) an electric field (perpendicular to the magnetic field) which oscillates at the particles' cyclotron frequency, or at a harmonic (multiple) of that frequency. (09 Oct 1997) |
| hybrid resonance | <radiobiology> A resonance in a magnetised plasma which involves aspects of both bunching of lighter species parallel to the magnetic field, characterised by the plasma frequency, and perpendicular particle motions (heavier species) characterised by the cyclotron frequency. (09 Oct 1997) |
| hydatid resonance | A peculiar vibratile resonance heard on auscultatory percussion over a hydatid cyst. (05 Mar 2000) |
| skodaic resonance | A peculiar, high-pitched sound, less musical than that obtained over a cavity, elicited by percussion just above the level of a pleuritic effusion. Synonym: Skoda's sign, Skoda's tympany. (05 Mar 2000) |
| nuclear magnetic resonance | Spectroscopic method of measuring the magnetic moment of atomic nuclei in a covalent bond. Clinical application is in biochemical, metabolic, and physiologic studies of living tissue. It includes proton and electron spin-echo and spin-relaxation times. (12 Dec 1998) |
| nuclear magnetic resonance, biomolecular | Nmr spectroscopy on small- to medium-size biological macromolecules. This is often used for structural investigation of proteins and nucleic acids, and often involves more than one isotope. (12 Dec 1998) |
| nuclear 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.
