【摘要】：目的探討超聲螢火蟲技術在檢測乳腺腫物微小鈣化中的臨床應用價值。方法收集已接受手術或穿刺活檢的乳腺腫物患者46例,常規(guī)超聲共發(fā)現(xiàn)69個腫物,選取經X線鉬靶攝影和病理結果均證實存在微小鈣化的56個腫物作為研究對象,分析56個腫物經常規(guī)超聲及螢火蟲成像技術檢測到腫物內微小鈣化情況,包括兩種技術發(fā)現(xiàn)微小鈣化的病灶例數,微小鈣化的形態(tài)及排列特征,比較常規(guī)超聲與螢火蟲技術顯示微小鈣化的差異。結果56個腫物中,病理證實惡性腫物42個,良性腫物14個,螢火蟲技術檢測到微小鈣化腫物48個,常規(guī)超聲檢測到微小鈣化腫物33個,二者差異有統(tǒng)計學意義(χ~2=11.84,P0.01),42個惡性腫物中,螢火蟲技術檢測到微小鈣化腫物39個,高于常規(guī)超聲的28個,差異有統(tǒng)計學意義(χ~2=8.07,P0.01)。螢火蟲技術檢測到良性腫物內微小鈣化9個,常規(guī)超聲檢出5個,差異無統(tǒng)計學意義(P0.05)。常規(guī)超聲檢出的鈣化灶大小形態(tài)不一,呈點狀(n=12)、短棒狀(n=6)及多種形態(tài)組合型鈣化(n=15),而螢火蟲技術顯示微小鈣化均呈現(xiàn)顆粒狀或細小的針尖樣強光點。常規(guī)超聲顯示的微小鈣化的分布特征為局域性(5例,其中惡性3例)、彌漫性散在分布(3例,其中惡性2例)、節(jié)段性(6例,其中惡性5例)及簇狀分布(19例,其中惡性18例)。螢火蟲技術顯示的微小鈣化分布則為局域性、彌漫性散在分布及簇狀分布。螢火蟲技術顯示的良、惡性乳腺腫物內微小鈣化的分布特征差異有統(tǒng)計學意義(χ~2=17.11,P0.01)。結論超聲螢火蟲技術可用于檢出乳腺腫物微小鈣化,在乳腺良惡性腫物鑒別、乳腺癌早期診斷及超聲引導下乳腺穿刺活檢方面具有重要的價值。
[Abstract]:Objective to evaluate the clinical value of ultrasonic firefly technique in detecting microcalcification of breast masses. Methods A total of 69 breast masses were detected by conventional ultrasound in 46 patients who had undergone surgery or puncture biopsy. Fifty-six masses with minimal calcification were selected as the study objects by mammography and pathology. The microcalcification in 56 masses was detected by conventional ultrasound and firefly imaging, including the number of lesions found by two techniques, the shape and arrangement of microcalcification. To compare the difference between conventional ultrasound and firefly technique in showing microcalcification. Results of the 56 tumors, 42 were malignant, 14 were benign, 48 were small calcified by firefly technique and 33 were detected by conventional ultrasound. The difference was statistically significant (蠂 ~ (2 +) 11.84 (P 0.01), P 0.01 (n = 42). There were 39 small calcified masses detected by firefly technique, which was higher than that of conventional ultrasound (28 cases). The difference was statistically significant (蠂 2 + 8.07%, P 0.01). Nine microcalcifications in benign tumors were detected by firefly technique and 5 by conventional ultrasound. The difference was not statistically significant (P 0.05). The size of calcified foci detected by conventional ultrasound was different in size, such as dotted and rod-shaped calcification (6) and various kinds of combined calcification. Firefly technique showed that tiny calcification showed granular or small pinniform intense light spots. The distribution of microcalcification showed by conventional ultrasound was localized in 5 cases, in which 3 cases were malignant, 3 cases were diffuse scattered, 2 cases were malignant, 6 cases were segmental, 5 cases were malignant) and 19 cases were clustered distribution, of which 18 cases were malignant. The microcalcification distribution showed by firefly technique was local, diffuse and cluster distribution. The distribution of microcalcification in benign and malignant breast masses was significantly different by firefly technique (蠂 ~ 2 ~ 2 ~ (17.11) P ~ (0.01). Conclusion Ultrasonic firefly technique can be used to detect small calcification of breast masses, which has important value in differentiating benign and malignant breast masses, early diagnosis of breast cancer and ultrasound guided breast biopsy.
