尽管艾滋病(AIDS)患者颅内淋巴瘤的发生率较高,目前的影像技术却难以将其与其它常见的非肿瘤病变加以区别。作者对~(201)T1单光子发射体层摄影(SPECT)识别AIDS病人颅内淋巴瘤的价值作了前瞻性研究。 研究对象为AIDS病人13例,男11例,女2例,26～47岁(平均34岁)。~(201)T1 SPECT以MR见到的有症状颅内肿块作参照,所有病例MR都在SPECT扫描24小时内进行。初次扫描后,所有病人都按弓形体病治疗,2～3周后MR复查,如无改善则考虑作活检,而后作系列的MR随诊。最终以活检或尸检所见为诊断依据,未能作活检者以临床标准和MR改变为依据。静注~(201)T13mCi后30分钟作SPECT扫描,采用超分辨率准直仪3头旋转伽
Despite the high incidence of intracranial lymphomas in AIDS patients, current imaging techniques have found it difficult to distinguish them from other common non-neoplastic lesions. The authors prospectively evaluated the value of ~ (201) T1 single photon emission tomography (SPECT) in the identification of intracranial lymphomas in AIDS patients. The subjects were AIDS patients in 13 cases, 11 males and 2 females, aged 26 to 47 (mean 34 years). ~ (201) T1 SPECT MR as seen in symptomatic intracranial masses for reference, all cases of MR were SPECT scans within 24 hours. After the initial scan, all patients were treated according to Toxoplasmosis, MR examination after 2 to 3 weeks, if no improvement is considered for biopsy, followed by a series of MR follow-up. Eventually biopsy or autopsy seen as the basis for diagnosis, failed to make biopsies based on clinical criteria and MR changes.
