Metastases and benign conditions of spine are common, however, the diagnoses of imaging modalities in the nature of spinal lesions are difficult, especially for the solitary lesions in spine. This study aims to retrospectively evaluate the diagnostic value of single photon emission computed tomography (SPECT)/spiral computed tomography (CT) in assessing indeterminate spinal solitary lesion of patients without certain medical history of malignancies. ⋯ Compared with SPECT imaging, hybrid SPECT/spiral CT imaging improves the diagnostic accuracy and specificity in evaluating indeterminate spinal solitary lesion of patients without certain malignant history. Moreover, based on whole-body bone scan with high sensitivity, cheap price, widespread and time-saving use, SPECT/spiral CT is a good imaging modality for the diagnosis and evaluation of the nature of solitary lesion in spine.
