答案:

参考答案:D

解析: 肺泡蛋白沉积症在MRI呈短T1长T2的特征性信号表现,与肺的其他渗出性病变明显不同,加之相应的临床表现,可作出判断;而其他几种疾病首先是MR信号不符合,其次,肺泡性肺水肿应有心衰表现,过敏性肺炎应有粉尘接触史,结缔组织病有各系统受累症状,皆与本病例不符。

     Fish contains lost of omega-3 fatty acids. These fatty acids have been shown to help prevent heart disease,

lower blood pressure and reduce the risk of strokes. Researchers suggest that these benefits of eating fish far

outweigh the risks of getting sick from contaminated fish.

     Ongoing studies find that omega-3 fatty acids work magic on the brain too. Pregnant? Go out and eat fish!

One study tracked a group of expectant women who ate more than 340 grams of fish per week. It turns out

they gave birth to children who, years later, scored really high on IQ tests.

     How can you add fish to your diet? One way to begin is by replacing meat with fish in one meal a week.

Instead of frying, which retains more fat, try boiling your fish in an oven or grilling it outdoors. And don't be

afraid to spice up your fish. Garlic, herbs other spices can add wonderful flavors to fish.

     For lighter meals, keep a few cans of tuna or other fish on hand at all times. They're great for making tasty

sandwiches or fish burgers. If you get hungry in the middle of the morning or afternoon, try tuna on crackers.

It's hard to find a better snack. And parents, be sure to introduce fish to your children. It's important for them

to get used to eating it at a young age.
