【摘要】：目的探究磁共振彌散加權(quán)成像(DWI)在均質(zhì)甲狀腺微小結(jié)節(jié)性質(zhì)判斷中的價(jià)值。方法選取經(jīng)手術(shù)病理證實(shí)的162例均質(zhì)甲狀腺微小結(jié)節(jié)患者,共226個(gè)病灶進(jìn)行磁共振常規(guī)掃描和DWI檢查。在226個(gè)均質(zhì)甲狀腺微小結(jié)節(jié)病灶的術(shù)后病理診斷中,良性結(jié)節(jié)47個(gè),惡性結(jié)節(jié)179個(gè)。將所得全部病灶的影像學(xué)數(shù)據(jù)進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果術(shù)后病理結(jié)果證實(shí)的47個(gè)良性結(jié)節(jié)中DWI呈高信號(hào)者13個(gè),等信號(hào)者32個(gè),低信號(hào)者2個(gè);179個(gè)惡性結(jié)節(jié)中DWI呈高信號(hào)者135個(gè),等信號(hào)者36個(gè),低信號(hào)者8個(gè)。取b值為0 s/mm~2時(shí),DWI掃描所得出的良性和惡性結(jié)節(jié)ADC值分別為(2.481±0.328)、(1.920±0.216)×10~(-3)mm~2/s;取b值為300 s/mm~2時(shí),ADC值分別為(2.322±0.528)、(1.634±0.387)×10~(-3)mm~2/s;取b值為500 s/mm~2時(shí),ADC值分別為(1.972±0.479)、(1.496±0.272)×10~(-3)mm~2/s;取b值為800 s/mm~2時(shí),ADC值分別為(1.675±0.503)、(1.247±0.248)×10~(-3)mm~2/s;取b值為1 000 s/mm~2時(shí),ADC值分別為(1.528±0.310)、(1.229±0.106)×10~(-3)mm~2/s;取b值為300、500和800 s/mm~2時(shí),良性和惡性結(jié)節(jié)DWI掃描所得出的ADC值差異有統(tǒng)計(jì)學(xué)意義(P均0.05);而在b值為0s/mm~2和1 000 s/mm~2時(shí),良性和惡性結(jié)節(jié)DWI掃描所得出的ADC值差異無統(tǒng)計(jì)學(xué)意義(P均0.05)。結(jié)論取b值為300、500和800 s/mm~2時(shí),應(yīng)用DWI掃描所得出的ADC值可用于判斷均質(zhì)甲狀腺微小結(jié)節(jié)的病變性質(zhì)。
[Abstract]:Objective to investigate the value of diffusion-weighted magnetic resonance imaging (DWI) in the diagnosis of small homogeneous thyroid nodules. Methods A total of 226 lesions were examined by conventional MRI and DWI in 162 patients with homogeneous thyroid micronodules confirmed by operation and pathology. Of 226 homogeneous thyroid micronodule lesions, 47 were benign and 179 were malignant. The imaging data of all lesions were analyzed statistically. Results among the 47 benign nodules confirmed by postoperative pathology, 13 had high signal DWI, 32 had equal signal intensity and 2 had low signal intensity, 135 had high signal DWI, 36 had equal signal intensity and 8 had low signal intensity in 179 malignant nodules. 鍙朾鍊間負(fù)0 s/mm~2鏃，
