Are the hyphens in this sentence correct? (particular attention to the high-signal and low-signal)
There are multiple round-to-ovoid lesions throughout the liver that are high-signal intensity on the T2-weighted images and low-signal intensity on the T1-weighted images.
I think they are correct based on pg 95 of BOS, but I am getting questioned about it and I want to make sure - I have been wrong a bunch before!Thanks

You know now questioning that again - just had a case where it was low lung volumes. It would not be low-lung volumes - therefore it seems like high signal intensity would be correct. This is really confusing me.
examples on BOS are: high-density mass low-frequency waves high-power field
I just can't figure out the difference. HELP!!

I would have to agree with whoever is questioning you. In the examples given in the BOS on that page (high-density mass, low-frequency waves, and high-power field), the hyphenated compound modifiers modify the following single noun: mass of high density, waves of low frequency, field of high power. In your sentence, however, low and high modify signal intensity. You are not discussing the intensity of low signal or high signal but rather high or low intensity of signal.
I also wouldn't hyphenate round to ovoid as I regard that as a range, but that could be argued either way.

In the case of low lung volumes, low modifies lung volumes, not lung. It's not a low lung; it's a low volume. Notice that you can say low volumes or lung volumes and nothing seems to be missing from the phrase.
In the case of high- and low-signal intensity, high and low modify signal and together they modify intensity. It's not a high intensity; it's a high signal. If you say high intensity, the question is high intensity what or high what intensity. You need high-signal to make the phrase make sense.
I also would not hyphenate round to ovoid. Although compound adjectives often have a preposition in the middle, I don't think that's the case here.
I'm a little pressed for time so my explanation may not be as clear as I'd like. Maybe ebit or 14tonks or Ann can step in and add to the discussion.
By the way, we're just finishing up a new issue of e-Perspectives on the Medical Transcription Profession, which will be posted to the HPI website in about a week. It has an article by me on hyphens and an article by Georgia Green on using PubMed to see what the current practice is in determining issues of this sort. I'll let you know when we upload the new issue and provide a link.

Do you know how to diagram a sentence? If you do, diagram it, and it should become clear. If you don't, all I can suggest is rearranging into a prepositonal phrase as I did above. It's not volume of low lung but low volume of lung.

Since 14tonks isn't reading this the way you are, we may have to wait for your return.
If you say high intensity, the question is high intensity what or high what intensity. You need high-signal to make the phrase make sense.
No, because I think the man means high intensity of signal, not intensity of high signal. One could say low intensity or signal intensity just as one could say low volumes or lung volumes.
But I, too, have been known to be wrong.

Okay so in the case of high signal intensity and low signal intensity - what is being modified here is the signal intensity so therefore no hyphen is to be used...Am I understanding. I like the explaination of asking self what is being modified. I am thinking I am understanding - am I?

If this were rearranged somewhat - say high-intensity signal - then the hyphen would be used?

Yes. Then you would be discussing a signal of high intensity, both words used as a compound modifier of signal.

Thanks for the invitation to pop in, Ellen, but I think 14tonks has covered it beautifully.

I am flattered, Ellen! I tend to avoid hyphens when I can (and to rely on when the presence or absence of hyphens and other punctuation "feels right" to me), so I know I am not really a reference, and I certainly can't come up with tonksian backup for my reasons.

Thanks, Tonks. I should never try to ansewr something when I'm pressed for time and don't have time to think it through. Your answer is perfect, and I yield to your better rationale.

Glad you agree with me after a second look, Ellen. We were both using the same rationale; I think you just didn't have the time on your first fly-by to analyze the whole context of that sentence.
