To report the incidence of early magnetic resonance imaging (MRI) terminations and analyse their risk factors in a large university hospital.
All consecutive patients aged > 16 years who underwent an MRI over a 14-month period were included. The following parameters were collected: demographics, in- or outpatient, history of claustrophobia, anatomical region investigated, and early MRI termination along with its cause. The potential link between these parameters and early MRI termination was statistically analysed.
Overall, 22,566MRIs were performed (10,792 [48%] men and 11,774[52%] women, mean age: 57 [range: 16-103] years). Early MRI termination was reported in 183 (0.8%) patients (99 men and 84 women, mean age: 63 years). Of these early terminations, 103 (56%) were due to claustrophobia and 80 (44%) to other causes. Early terminations were more common in inpatients than outpatients (1.2% vs. 0.6%, p < 0.001), for both claustrophobia- and non-claustrophobia-related reasons. A prior history of claustrophobia was strongly associated with claustrophobia-related early termination (6.6% vs. 0.2%, p = 0.0001). Non-claustrophobia-related early terminations were significantly more common (0.6% vs. 0.2%) in elderly patients (>65 years old) than in younger ones. No other parameter was significantly associated with early termination.
Early MRI termination is currently rare. The main risk factors for claustrophobia-related terminations comprised a prior history of claustrophobia, and examinations in inpatients. Non-claustrophobia-related early terminations were more common in both elderly patients and inpatients.
报告在一家大型大学医院进行的早期磁共振成像（MRI）中止的发生率，并分析其危险因素。
纳入了在 14 个月期间进行 MRI 的所有年龄大于 16 岁的连续患者。收集了以下参数：人口统计学，门诊或住院，幽闭恐惧症史，检查的解剖区域，以及早期 MRI 中止及其原因。对这些参数与早期 MRI 中止之间的潜在联系进行了统计学分析。
总共进行了 22566 次 MRI（10792 名男性[48%]和 11774 名女性[52%]，平均年龄：57 岁[范围：16-103]）。报告了 183 例（0.8%）患者发生早期 MRI 中止（99 名男性和 84 名女性，平均年龄：63 岁）。其中，103 例（56%）因幽闭恐惧症，80 例（44%）因其他原因中止。住院患者中早期中止的发生率高于门诊患者（1.2%对 0.6%，p<0.001），无论是幽闭恐惧症相关还是非幽闭恐惧症相关的原因。先前有幽闭恐惧症史与幽闭恐惧症相关的早期中止有很强的相关性（6.6%对 0.2%，p=0.0001）。非幽闭恐惧症相关的早期中止在老年患者（>65 岁）中比年轻患者更常见（0.6%对 0.2%）。没有其他参数与早期中止显著相关。
早期 MRI 中止目前很少见。幽闭恐惧症相关中止的主要危险因素包括先前的幽闭恐惧症史和住院患者检查。非幽闭恐惧症相关的早期中止在老年患者和住院患者中更为常见。
