摘要

目的分析骨样骨瘤的全身骨扫描（WBS）和SPECT/CT影像学特征。方法自2010年1月至2018年12月，在西南医科大学附属医院收治经病理证实的骨样骨瘤患者70例（男50例，女20例，年龄4-66岁）。所有患者均行WBS和SPECT/CT检查，并对其影像学特征进行回顾性分析。结果WBS结合SPECT/CT共发现70处病变，股骨26处（37.1%，26/70），胫骨25处（35.7%，25/70）。在56例接受三期骨显像的患者中，靶病变与非靶病变的放射性比值（T/NT）为3.7±1.2。WBS显示48个病灶（68.6%，48/70）为圆形（或近圆形），21个病灶（30%，21/70）为梭形，1个病灶（1.4%，1/70）为不规则形状，SPECT/CT成像显示69个病灶（98.6%，69/70）为圆形或圆形，1个病变（1.4%，1/00）为不规形。WBS显示48个病灶（68.6%，48/70）出现“双密度征”，SPECT/CT显示59个病灶（84.3%，59/70）出现双密度征。SPECT/CT成像在59个病变（84.3%，59/70）中检测到病灶，在27个病变（38.6%，27/70）中检测出钙化或骨化（“靶征”）。结论骨样骨瘤的WBS和SPECT/CT影像学特征包括“双密度征”、病灶和“靶征”，有助于骨样骨癌的诊断。关键词：骨肉瘤、类骨；放射性核素成像；层析成像，发射计算机，单光子；层析成像，X射线计算机；99m甲基戊酸锝

Analysis of whole-body bone scintigraphy and SPECT/CT imaging in osteoid osteoma

Objective To analyze features of osteoid osteoma on whole-body bone scan (WBS) and SPECT/CT imaging. Methods From January 2010 to December 2018, 70 patients (50 males, 20 females, age: 4-66 years) with osteoid osteoma confirmed by pathology were enrolled from the Affiliated Hospital of Southwest Medical University. All patients underwent WBS and SPECT/CT imaging and imaging features were retrospectively analyzed. Results A total of 70 lesions were found by WBS combined with SPECT/CT imaging, and 26 lesions (37.1%, 26/70) were found in the femur and 25 lesions (35.7%, 25/70) in the tibia. The radioactive ratio of target lesion to non-target lesion (T/NT) was 3.7±1.2 in 56 patients who underwent three-phase bone imaging. WBS showed that 48 lesions (68.6%, 48/70) were round (or nearly round), 21 lesions (30%, 21/70) were spindle-shaped, and 1 lesion (1.4%, 1/70) was irregular-shaped, while SPECT/CT imaging showed that 69 lesions (98.6%, 69/70) were round (or round) and 1 lesion (1.4%, 1/70) was irregular-shaped. The " double-density sign" was found in 48 lesions (68.6%, 48/70) by WBS and in 59 lesions (84.3%, 59/70) by SPECT/CT imaging. SPECT/CT imaging detected nidus in 59 lesions (84.3%, 59/70) and calcification or ossification (" target sign" ) in 27 lesions (38.6%, 27/70). Conclusion The typical features of osteoid osteoma on WBS and SPECT/CT imaging include " double density sign" , nidus and " target sign" , which contribute to the diagnosis of osteoid osteoma.

期刊介绍： Chinese Journal of Nuclear Medicine and Molecular Imaging (CJNMMI) was established in 1981, with the name of Chinese Journal of Nuclear Medicine, and renamed in 2012. As the specialized periodical in the domain of nuclear medicine in China, the aim of Chinese Journal of Nuclear Medicine and Molecular Imaging is to develop nuclear medicine sciences, push forward nuclear medicine education and basic construction, foster qualified personnel training and academic exchanges, and popularize related knowledge and raising public awareness. Topics of interest for Chinese Journal of Nuclear Medicine and Molecular Imaging include: -Research and commentary on nuclear medicine and molecular imaging with significant implications for disease diagnosis and treatment -Investigative studies of heart, brain imaging and tumor positioning -Perspectives and reviews on research topics that discuss the implications of findings from the basic science and clinical practice of nuclear medicine and molecular imaging - Nuclear medicine education and personnel training - Topics of interest for nuclear medicine and molecular imaging include subject coverage diseases such as cardiovascular diseases, cancer, Alzheimer’s disease, and Parkinson’s disease, and also radionuclide therapy, radiomics, molecular probes and related translational research.
