放射性坏死

Autoradiography results confirmed the extravasation of radiolabeled SCKs in vascularized areas of the tumor, whereas no diffusion was observed in necrotic regions.

放射自显影法的结果证实，放射性标记的SCK在肿瘤血管化区域溢出，而坏死区域观察不到扩散现象。

18F-FDG PET is more sensitive and accurate than MRI in differentiating radionecrosis and recurrence of gliomas after interstitial brachytherapy.

18F-FDG PET在胶质瘤间质内放疗后区分放射性坏死与肿瘤复发方面较MRI更敏感而准确。

BACKGROUND: Radionecrosis of the larynx is uncommon and usually occurs among laryngeal cancer patients who have undergone radiotherapy. Patients with severe radionecrosis were reviewed for analysis and discussion of symptoms and managements.

背景： 放射性喉部坏死并不常见，通常认为只发生在接受放射治疗而未接受全喉切除的喉癌或下咽癌患者身上。

Objective To investigate the differential diagnosis value of 1H magnetic resonance spectroscopy (1H-MRS) and (superscript 99m)Tc-methoxy isobutyl isonitrile single photon emission computed tomography on postradiotherapy relapse and radionecrosis. Methods 1H-MRS and SPECT were performed in all 35 cases.

目的 探讨质子磁共振波谱(1H-MRS)和99mTc-甲氧基异丁基异腈单光子发射计算机断层显像对脑肿瘤患者放疗后复发与放射性坏死的鉴别诊断作用。

The median weight loss was 18 lb (range, 0–47 lb). Eight patients (16%) deeloped aspiration pneumonia during and after treatment. Fie patients (10%) died of aspiration (2 during and 3 post treatment). Four patients (8%) deeloped esophageal strictures requiring repeated dilatations post treatment. Two patients had radionecrosis (1 soft tissue and 1 bone) requiring hyperbaric oxygen. Eighteen patients (37%) had prolonged tube feedings (N3 months) after treatments because of seere dysphagia or aspiration.

体重减轻中值为18磅（范围，0-47磅）。8例患者（16％）在治疗期间和治疗后发生吸入性肺炎。5例患者(10%)死于误吸（2例在治疗期间，3例在治疗后）。4例患者(8%)治疗后发生食道狭窄需要反复食道扩张。2例患者有放射性坏死（1例为软组织，1例为骨）需要高压养治疗。8例患者(37%)治疗后因为严重的吞咽困难和误吸而持续管饲。

Compared with the pathological examinations of the 21 cases, the accuracy of distinguishing recurrent tumor was 61.9% and 90.5% for mri and for pet respectively. conclusion 18f-fdg pet is more sensitive and accurate than mri in differentiating radionecrosis and recurrence of gliomas after interstitial brachytherapy.

18f-fdg pet在胶质瘤间质内放疗后区分放射性坏死与肿瘤复发方面较mri更敏感而准确。

Like Thallium SPECT, the PET scan has been very useful in differentiating tumor recurrence and radiation necrosis.

同铊标记SPECT一样，PET扫描对于区分肿瘤复发和放射性坏死十分有效。

Objective To analyze the mechanism of action of Fuzheng Qingre Decoction for radioactivity rectal injury by comparison of pathological change and tumor necrosis factor expression in intestinal mucosa of radiation proctitis rat.

目的 通过比较实验组和对照组放射性直肠炎大鼠模型肠黏膜的病理变化及肿瘤坏死因子-α表达分析清热扶正汤对放射性直肠损伤的作用机制。

Methods A total of 55 cases including glioblastoma ( n =17), metastasis ( n =19), radiation necrosis ( n =11) and brain abscess ( n =8) were analyzed.

55例脑内环状强化病灶，胶质母细胞瘤17例、转移瘤19 例、放射性坏死11 例，脑脓肿8 例。
