项目摘要

There is a demand for validation of the benefits of medical practices and a weighting of their benefits against their costs. Partly in response to these pressures, considerable recent activity has been devoted to the development of measures appropriate for evaluating the impact of various medical technologies on patient health outcomes and the cost of medical care. However, these efforts largely have focused on therapeutic technologies and medical organizational systems. Little such research has been directed toward diagnostic technologies, including diagnostic imaging technologies, which are among the most prominent in their potential for affecting care and cost. The purpose of this project was to evaluate the impact of MR imaging on decisions about treatment of patients with clinically diagnosed pelvic endometriosis. I investigated to generalize about the usefulness of the correct diagnostic technique in eliminating unnecessary costs.MR imaging of the pelvis affects the overall cost of diagnosis and treatment of endometriosis by reducing the number of unnecessary surgical procedure. With pelvic MR imaging, the origin of an adnexal mass can be differentiated reliably, even when other imaging findings are equivocal, a further contribution to the elimination of unnecessary surgery. When MR imaging was done in all patients with suspected endometriosis before laparoscopy, an overall net saving of 770460 yen or 22013 yen per patient.In patients with suspected ovarian diseases, the use of pelvic MR imaging decreased the number of invasive surgical procedures and reduced total health care costs. QALY (quality adjusted life expectancy years) in addition of MR imaging showed an increase of 0.15 over those of conventional technique only.

有一个需求，以验证医疗做法的好处，并权衡其好处对他们的成本。部分为了应对这些压力，最近开展了大量活动，专门制定适当的措施，以评估各种医疗技术对患者健康结果和医疗费用的影响。然而，这些努力主要集中在治疗技术和医疗组织系统上。很少有这样的研究是针对诊断技术，包括诊断成像技术，这是其中最突出的影响护理和成本的潜力。本项目的目的是评估MR成像对临床诊断为盆腔子宫内膜异位症患者治疗决策的影响。我调查了正确的诊断技术在消除不必要的费用方面的有用性。盆腔MR成像通过减少不必要的手术次数影响了子宫内膜异位症的诊断和治疗的总费用。盆腔MR成像可以可靠地鉴别附件包块的来源，即使其他影像学检查结果不明确，也有助于消除不必要的手术。如果在腹腔镜检查前对所有疑似子宫内膜异位症患者进行MR成像，则每例患者的总净节省为770460日元或22013日元。在疑似卵巢疾病患者中，使用盆腔MR成像减少了侵入性手术的次数，降低了总医疗费用。QALY（质量调整的预期寿命年），除了磁共振成像显示，增加了0.15比传统技术。
