It is challenging to obtain a similar access to positron emission tomography/computed tomography (PET-CT) within the whole region served. In the subarctic and arctic region of Norway, significant distances, weather conditions and seasonable darkness have been challenging when the health care provider has aimed for a high quality PET-CT service with similar availability to all inhabitants.
The PET-CT service at the University Hospital of North Norway (UNN) was established in May 2010. The glucose analogue tracer fluorine-18 fluorodeoxyglucose (FDG) was delivered from Helsinki, Finland. An ambulatory PET-CT scanner was initially employed and a permanent local one was introduced in October 2011. In March 2014, we analysed retrospectively all data on the PET-CT exams performed at the Section of Nuclear Medicine, Department of Radiology during a 32 months time period 2010-13. The following patient data were recorded: gender, age, diagnosis, residence and distance of travelling. There were in total 796 exams in 706 patients.
Four hundred sixty-one PET-CT exams per million inhabitants were, on average, performed per year. Lung cancer (32.7%), malignant melanoma (11.3%), colorectal cancer (10.9%) and lymphoma (9.7%) constituted two-thirds of all exams. Three-fourths were males and the median age was 63.5 years (range 15.2-91.4 years). The access to PET-CT exam varied within the region. The southern county (Nordland) experienced a significantly less access (p < 0.0001) to the regional service. Except for malignant melanoma, this finding was observed in all major cancer subgroups. In colorectal cancer and lymphoma a lower consumption of PET-CT was also observed in the northeastern county (Finnmark). Patients' mean distance of travelling by car (one way) was 373 km (median 313 km, range 5-936 km).
PET-CT was not similarly available within the region. Especially, inhabitants in the southern county experienced less access to the regional service. National and regional standards of care, new scanners and improved collaboration between hospital trusts may alter this situation.
在整个服务区域内实现类似的正电子发射断层扫描/计算机断层扫描（PET-CT）检查机会具有挑战性。在挪威的亚北极和北极地区，当医疗服务提供者旨在为所有居民提供具有类似可及性的高质量PET-CT服务时，路途遥远、天气条件以及季节性黑暗一直是难题。
挪威北部大学医院（UNN）的PET-CT服务于2010年5月设立。葡萄糖类似物示踪剂氟-18氟脱氧葡萄糖（FDG）从芬兰赫尔辛基运送而来。最初使用的是一台移动式PET-CT扫描仪，并于2011年10月引入了一台固定式本地扫描仪。2014年3月，我们回顾性分析了2010年至2013年这32个月期间在放射科核医学科进行的PET-CT检查的所有数据。记录了以下患者数据：性别、年龄、诊断、居住地和出行距离。706例患者共进行了796次检查。
平均每年每百万居民进行461次PET-CT检查。肺癌（32.7%）、恶性黑色素瘤（11.3%）、结直肠癌（10.9%）和淋巴瘤（9.7%）占所有检查的三分之二。四分之三为男性，中位年龄为63.5岁（范围15.2 - 91.4岁）。该地区内PET-CT检查的可及性存在差异。南部县（诺尔兰）获得区域服务的机会明显较少（p < 0.0001）。除恶性黑色素瘤外，在所有主要癌症亚组中均观察到这一现象。在结直肠癌和淋巴瘤方面，东北部县（芬马克）的PET-CT使用量也较低。患者驾车出行的平均距离（单程）为373公里（中位值313公里，范围5 - 936公里）。
该地区内PET-CT的可及性并不相同。特别是，南部县的居民获得区域服务的机会较少。国家和地区的护理标准、新的扫描仪以及医院信托之间更好的协作可能会改变这种情况。
