Oral hydration with large volume of fluid, high dose of diuretics and maximum bladder distension are frequently required to achieve an adequate urinary FDG clearance in an FDG PET/CT protocol for bladder cancer or pelvic tumour evaluation. Although most patients tolerated these procedures for eliminating urinary FDG activity, these procedures may be still unpleasant.
Is there a more patient-friendly protocol which is less burdensome and yet provides a satisfactory FDG clearance in urine? In this study, we established a patient-friendly FDG PET/CT protocol without compromising urinary FDG clearance.
PATIENTS, METHODS: 23 patients with biopsy-proven urinary bladder cancers were recruited to evaluate the effectiveness of this patient-friendly protocol on reducing urinary bladder FDG activity. The patient-friendly protocol includes encouraging patients to take a tolerable amount of fluid, delaying the administration of low dose diuretic, shortening the urine holding time and using delayed imaging.
All of the patients tolerated this patient-friendly procedure well. In addition, the patient-friendly protocol was effective in reducing FDG activity in the urine. One hundred percent of primary bladder cancer were visualized on the FDG PET/CT images using this patient-friendly protocol.
This patient-friendly FDG PET/CT protocol is less intrusive yet effective in reducing urinary FDG activity.
在用于膀胱癌或盆腔肿瘤评估的FDG PET/CT检查方案中,通常需要大量口服补液、大剂量利尿剂以及使膀胱最大限度充盈,以实现足够的尿液FDG清除。尽管大多数患者能够耐受这些清除尿液中FDG活性的操作,但这些操作仍可能会让患者感到不适。
是否存在一种对患者更友好的方案,既能减轻负担,又能在尿液中实现令人满意的FDG清除?在本研究中,我们建立了一种对患者友好的FDG PET/CT检查方案,同时不影响尿液中FDG的清除。
患者、方法:招募了23例经活检证实为膀胱癌的患者,以评估这种对患者友好的方案在降低膀胱FDG活性方面的有效性。对患者友好的方案包括鼓励患者摄入可耐受量的液体、延迟给予低剂量利尿剂、缩短憋尿时间以及采用延迟成像。
所有患者对这种对患者友好的操作耐受性良好。此外,该对患者友好的方案在降低尿液中FDG活性方面有效。使用这种对患者友好的方案,100%的原发性膀胱癌在FDG PET/CT图像上得以显示。
这种对患者友好的FDG PET/CT检查方案侵入性较小,但在降低尿液中FDG活性方面有效。
