白血病和淋巴瘤在X線光譜中顯影嗎

Neither leukemia nor lymphoma is diagnosed by imaging. Initial diagnosis typically requires biopsy and a number of laboratory tests that are performed on the blood and tissue samples. Imaging tests for leukemia, in particular, may not be as helpful as in other types of cancer that form tumors.

白血病和淋巴瘤都不能用影像學確診。最初的診斷通常需要在血液和組織樣本中進行活檢和實驗室測試。尤其是白血病的成像檢測,在其他類型的癌症形成的腫瘤中可能沒有用。

That said, even in leukemia, and often in lymphoma, plain x-ray images can offer clues that, taken together with other bits of information, may be part of the workup that ultimately leads to a biopsy and a diagnosis.

那就是說即使在白血病和淋巴瘤檢測中,普通X射線圖像結合其他信息可以提供一些線索, 通過這部分檢查，最終可能得到活組織檢查和診斷結果。

With respect to lymphoma, the patterns of lymph node involvement, which may be revealed even by chest x-rays, can be very important initially to help narrow down the possibilities. Not all swollen lymph nodes in the chest are lymphoma. Other cancers, infection, and nonmalignant diseases like sarcoidosis may be to blame. Sometimes swollen lymph nodes are in easily accessible locations for biopsy, such as the neck; however, in other cases—in Hodgkin lymphoma, for instance—the only cancerous lymph nodes might be located deep within the chest.

關於淋巴瘤，胸部的X光檢查可能揭示淋巴結的轉移類型, 最初可以幫助減小病情發生的可能性。在胸部，並非所有的淋巴結腫大都是淋巴瘤。其他癌症、感染和良性疾病像肉狀瘤病可能是罪魁禍首。有時淋巴結腫大對活檢來說，應該在容易檢測的位置如頸部；然而,在其他情況下-例如霍奇金淋巴瘤-僅有的位於胸腔深處的淋巴結癌。

X-rays, or plain films, are not used to diagnose leukemia. However, a chest x-ray might be done to check for a lung infection or for some other reason, and the x-ray might also show swollen lymph nodes and other areas of disease. Some forms of leukemia may spread to the lymph nodes as the disease progresses.

X射線或腹部平片不用於診斷白血病。然而,肺部感染或一些其他原因可能會用到胸部X光。X射線也可顯示淋巴結腫大和其他領域的疾病。隨着淋巴結疾病的進展，某些形式的白血病可能擴散。

In addition, radiologists, or doctors who interpret radiographic imaging, look at the patterns of disease involvement, or lesions, in the bone.

此外, 解釋射線成像的放射科醫生或某些醫生,會觀察骨頭裏疾病的類型或病變。

Leukemia and many non-cancerous diseases that interfere with bone metabolism, such as hyperparathyroidism and osteoporosis, may have a symmetrical distribution in the skeleton. In contrast, a haphazard, asymmetric appearance of bone lesions may suggest a different cause, such as Paget’s disease of the bone or metastatic spread of some other kind of cancer.

白血病和許多非腫瘤疾病都影響骨代謝,像甲狀旁腺機能亢進和骨質疏鬆症在骨架中可能有一個對稱分佈。相比之下,一個偶然的、不對稱的骨骼病變可能表明不同的原因，比如佩吉特氏骨病或其他類型癌症的轉移擴散等。
