CT scan results "good" but confusing

So they're going to do a breast and thorax MRI in a couple of weeks. What's confusing is the following aobut my lungs: "questionable nodules along the lower lobes bilaterally." The oncologist says that anything bilateral (both sides, same thing) is usually not cancerous, but my mother (a registered nurse) said the following: "There may be some plugs in the alveoli in the bottom of your lungs causing a problem in coughing and the fluid or sponginess there. Cells may be cancer cells that haven’t 'learned their lesson' yet and died. They will. Or may be plugs of mucus from a cold or infection. Infections can occur with the chemo treatment." Thanks, Mom.

Anyway, I get to have scanxiety about the MRI now. Sigh. Otherwise, the CT is a "no progression" type and I guess I should be happy about that. But the oncologist wasn't able to tell me when I'd be able to go off chemo, and I so desperately want my life back that I found that discouraging. I really am happy about the no progression, though.

So, I'm going to just type in the scan results. Maybe someone here who's more medically savvy can offer additional insights. Like what does the radiologist mean by "dependent changes"?

CT Chest ad abdomen with contrast

FINDINGS: There is again a nodule along the left upper lob presenting measuring 8mm, previoulsy measuring 9mm. There are questionable nodules posteriorly along the subpleural location along the lower lobes bilaterally. These may represent dependent changes. A subpleural nodule adjacent to the right middle lobe is stabel from 7/01/09 and present since 10/01/08.

There is no mediastinal, hilar, or axillary adenopathy. There is no internal mamillary adenopathy.

The liver, spleen, pancreas, gallbladder, adrenal glands, and kidneys are unremarkable. (YAY!)

The visible portions of the hollow viscera are unremarkable.

There is no intraabdominal or retroperitoneal adenopathy.

Again, a sclerotic lesion along the right eighth rib is seen. This is slightly more prominent from 07/01/09.

Twho nodules seen along the right breast have been present since 10/01/08.

IMPRESSSION:

1. No evidence of progression of metastaic disease. (I LIKE THIS SENTENCE.) Nodular density posterior lower lobes bilaterally may represent dependent changes, attention on follow up.

2. Two nodular densities along the right breast have been present and stable from 10/01/08. Please correlate with physical examination and mammograms.

3. Sclerotic lesion right eighth rib, slightly more prominent when compared to 07/01/09. Fracture line is seen. Some of this could be due to healing versus progression of metastasis.
