interference (redirected from ultrasound interference lines)

in·ter·fer·ence (ntr-fîrns)

n.

1. The variation of wave amplitude that occurs when waves of the same or nearly the same frequency come together.

2. The condition in which infection of a cell by one virus prevents superinfection by another virus.

3. The condition in which superinfection by a second virus prevents effects that would result from infection by either virus alone, even though both viruses persist.

interference [in″ter-fēr´ens]

1. opposition to or hampering of some activity.

2. impairment of cardiac impulse conduction due to refractoriness of the tissue; the refractoriness is a physiological response to passage of a preceding impulse.

3. a premature contact point on the occlusal surface of the teeth.

electromagnetic interference electrical signals of nonphysiological origin that may affect pacemaker function; they can either inappropriately inhibit pacemaker output or trigger unnecessary pulses. Pacemakers with bipolar leads are less sensitive to this.

occlusal i's areas of interference on teeth that hamper proper occlusion and smooth, gliding, harmonious jaw movements.

ultrasound interference lines

in ultrasonography, white lines across the image, usually caused by poor contact between the skin and transducer.

interference

Modification of light intensity arising from the joint effects of two or more coherent trains of light waves superimposed at the same point in space and arriving at the same instant. The waves may either reinforce each other, being in phase (constructive interference) or cancel each other, being out of phase (destructive interference). See coherent sources; Young's experiment; holography; phase; optical coherence tomography.

Patient discussion about interference.

Q. Does omega-3 interfere with diabetes treatment? I’m a 55 years old man, and was diagnosed with diabetes mellitus, along with high lipid levels several years ago. A couple of months ago I read that omega-3 can protect your heart and brain, so I started to take omega-3 pills every day. Yesterday I read in some website that omega-3 can interfere with the drugs I take to treat my diabetes- Is that right?

A. Omega-3 doesn’t influence the treatment of your diabetes, and since you have high lipids, that can contribute to some of the damage diabetes does to your body, omega-3, that may lower the lipid level in your may actually help you treat yourself overall better. However - consult your doctor. Better be safe than sorry...

Q. Will my bipolar meds (lamictal and depakote) interfere with my birth control pills? We have been married for the past 12 yrs but we don’t have a child because I am paranoid of delivery. But it doesn’t affect our intimacy. I am using birth control pills for the past few years and I could rely on it. Now the new problem is that I was recently diagnosed as bipolar-II. The Doctor prescribed some medicines for me. Will my bipolar meds (Lamictal and Depakote) interfere with my birth control pills?

A. there are interactions, birth control pills can reduce the amount of Lamictal in the blood, causing it to be less affective. the drug level in plasma should be monitored. ask both your therapists about it- your gynecologist and the psychiatrist.

Q. What to do as this is interfering with my profession and my family? My sister is spinster and she keeps complaining of feeling dizzy when she wakes up and invariably says that she has constant headaches. Almost every day she feels so stiff that we have to help her out of bed. I do not know whether she feels helpless as she keeps saying that she feels anxious. Please tell me what to do as this is interfering with my profession and my family and my wife suspects her to be having fibromyalgia.

A. well....she is your sister. i understand that it is probably bothering but if you won't help her, who will?
i think the first stage is tom properly diagnose it. get a good Dr. and if it's really Fibromyalgia you can go on to the next stage - treating it right. Fibromyalgia may not have a cure but it sure has a treatment. with a treatment it might be easier on you to help her.
