用~(99m)Tc亚氨二乙酸衍生物行胆道显像时所显示出的靠近胆囊窝处肝脏放射活性增强的现象:称为“边缘征”。据报道边缘征并有胆囊不显影时与坏疽性和/或急性胆囊炎有关。作者报道39例病人,男18例,女21例,平均年龄54岁(22～92岁)。病人均行胆囊切除术,经病理学证实为急性和/或慢性胆囊炎。术前测定肝功能,包括转氨酶和碱性磷酸酶。标准的DISIDA(2,6-二异丙基苯甲酰甲基亚氨二乙酸)扫描方法包括:静注6 mCi~(99m)锝DISIDA放射性同位素,在5、15、30、45和60分钟时仰卧位用平行光管在腹前部照相。正常情况下注药后60分钟可显示胆囊及小肠,若60分钟时胆囊仍不显影,则继续照相至注药后4小时。边缘征的表现为解剖上相当于胆囊窝的区域有放射性同位素的活性增强。
Bile duct imaging with ~ (99m) Tc iminodiacetic acid derivatives showed an increase in radioactivity near the gallbladder fossa: a “marginal sign.” Frontogenesis and / or acute cholecystitis have been reported on borderline and gallbladder non-visualization. The authors reported 39 patients, 18 males and 21 females, with an average age of 54 years (22 to 92 years). Patients underwent cholecystectomy, pathologically confirmed as acute and / or chronic cholecystitis. Preoperative determination of liver function, including transaminases and alkaline phosphatase. The standard DISIDA (2,6-diisopropylphenacyliminodiacetic acid) scanning method consists of intravenous 6 mCi ~ (99m) technetium DISIDA radioisotopes at 5, 15, 30, 45 and 60 minutes When the supine position with a parallel tube in the anterior abdominal camera. Under normal circumstances 60 minutes after injection can show the gallbladder and small intestine, if 60 minutes when the gallbladder is still not developing, then continue to photograph to 4 hours after injection. Marginal signs of the performance of anatomically equivalent to the gallbladder litter area has increased radioisotope activity.
