探讨不同类型细支气管肺泡癌的HRCT形态学表现与FDG PET SUV值的相关性。回顾性地分析经病理证实的28例细支气管肺泡癌患者的FDG PET和HRCT的影像资料,分别记录分析其形态学改变特点及FDG摄取程度和摄取特点,同时测量其最大SUV值(SUVmax),将不同形态的细支气管肺泡癌影像与所测得的最大SUV值进行对比研究。28例中单发结节13例,其中磨玻璃密度结节5例,直径1.1—2.8 cm,SUVmax值均<1.5。4例结节边缘可见分叶,2例可见胸膜牵拉、凹陷,2例见血管聚集;8例实性结节,直径1.8—3.8 cm,SUVmax值4.8—8.3。边缘短毛刺7例,分叶7例,支气管充气症6例,空泡症5例,胸膜凹陷症3例,血管集聚症7例,结节堆聚症3例。多发结节型9例,其中4例为粟粒性结节,5例表现为2个以上结节,磨玻璃密度结节、小的粟粒结节(<3 mm)无FDG摄取,融合结节,大于3 mm的粟粒结节可见FDG摄取,SUVmax值在2.1—3.9。肺炎型6例,单肺叶受累4例,双肺叶受累2例,表现为病变肺叶内大片状实变影,7例可见支气管充气、支气管扭曲、僵硬,1例见空洞影,1例见支气管截断,3例见支气管管壁不规则增厚,PET显示实变病灶内FDG摄取不均匀增高,最大SUVmax值4.5—11.8。说明细支气管肺泡癌HRCT所示的形态学表现与PET所测得SUV值之间存在一定的相关性。磨玻璃密度影、小于3 mm的粟粒结节影大多数无异常FDG摄取,肺炎型和肿块型则多数具有较高的FDG摄取。
To investigate the correlation between HRCT morphology and FDG PET SUV of different types of bronchioloalveolar carcinoma. The imaging data of FDG PET and HRCT in 28 patients with bronchioloalveolar carcinoma confirmed by pathology were retrospectively analyzed. Morphological changes, the extent of FDG uptake and the uptake of FDG were recorded and analyzed. The maximum SUV value, The different forms of bronchioloalveolar carcinoma images were compared with the measured maximum SUV values. Thirteen patients had solitary nodules in 28 cases, including 5 cases of ground-glass density nodules, 1.1-2.8 cm in diameter, SUVmax values <1.5.4, visible border of nodules, 2 pleura pulls, 2 For example, vascular aggregation; 8 cases of solid nodules, diameter 1.8-3.8 cm, SUVmax values 4.8-8.3. Short edge burr in 7 cases, lobectomy in 7 cases, bronchial inflamation in 6 cases, 5 cases of vacuolar disease, 3 cases of pleural indentation, vascular aggregation in 7 cases, nodules in 3 cases. Multiple nodules in 9 cases, of which 4 cases were miliary nodules, 5 cases showed more than two nodules, ground glass density nodules, small miliary nodules (<3 mm) without FDG uptake, fusion nodules, Miliary nodules larger than 3 mm showed FDG uptake with SUVmax values of 2.1-3.9. Pneumonia type in 6 cases, single lung involvement in 4 cases, double lung involvement in 2 cases, the performance of lesions in the lobe of large solidified shadow, 7 cases of bronchial inflation, bronchial distortions, stiff, 1 case of hollow, 1 case of bronchus Truncated, 3 cases of irregular thickening of the bronchial wall, PET showed solidified lesion FDG uptake increased unevenly, the maximum SUVmax value of 4.5-11.8. Description of bronchioloalveolar carcinoma HRCT showed morphological performance and PET measured SUV value there is a certain correlation between. Abrasive glass density, less than 3 mm miliary nodules most of the non-abnormal FDG uptake, pneumonia and mass type most of the FDG uptake.
