Abstract

This work aimed to analyze the diagnostic value of dynamic scanning of multislice spiral computed tomography (MSCT) and magnetic resonance imaging (MRI) for benign and malignant bone tumor and nursing intervention. 108 patients with bone tumor were selected as the research objects, all of which underwent MSCT and MRI scans. The accuracy, sensitivity, and specificity of MSCT, MRI, and MSCT + MRI for identifying benign and malignant bone tumors and nursing care were calculated, as well as the diagnostic accuracy of MSCT, MRI, and MSCT + MRI for different bone tumor pathological types. The results showed that the accuracy of MSCT + MRI (97.56%) in distinguishing benign and malignant bone lesions was remarkably higher relative to that of MSCT (85.91%) and MRI (89.85%) ( P < 0.05 ). The sensitivity and specificity of MSCT + MRI (94.85%; 90.52%) in distinguishing benign and malignant bone lesions were obviously greater in contrast to those of MSCT (83.66%; 79.05%) and MRI (86.02%; 81.17%) ( P < 0.05 ). The malignant misdiagnosis rate and malignant missing report rate of MSCT + MRI in distinguishing benign and malignant bone lesions were inferior to those of MSCT and MRI notably ( P < 0.05 ). The accuracy of MSCT + MRI in distinguishing osteosarcoma, giant-cell tumor of bone (GCT), bone cyst, and osteofibrous dysplasia (OFD) was evidently higher versus that of MSCT and MRI ( P < 0.05 ). The accuracy of MSCT + MRI in distinguishing osteofibroma and ganglioneuroma was greatly higher than that of MSCT and MRI ( P < 0.05 ). The accuracy of MSCT + MRI in distinguishing osteofibroma and ganglioneuroma was 68.64% and 71.63%, respectively. In short, in contrast to the single MSCT and MRI examination, MSCT combined with MRI detection can effectively improve the accuracy of judgment for benign and malignant bone tumor lesions and nursing care and had higher sensitivity and specificity. MSCT combined with MRI had better performance in identifying osteosarcoma, GCT, bone cyst, and OFD but poor performance in osteofibroma and ganglioneuroma.

Highlights

Bone lesions mainly refer to bone structure or sclerotin lesions
It was similar to the results of Caers et al [16], showing that compared with the single MSCR and magnetic resonance imaging (MRI), multislice spiral computed tomography (MSCT) combined with MRI detection can more effectively improve the accuracy of the diagnosis of malignant bone tumor. e sensitivity and specificity of MSCT + MRI in distinguishing benign and malignant bone lesions were better than those of MSCT and MRI (P < 0.05), revealing that MSCT combined with MRI detection had high sensitivity and specificity for the diagnosis of malignant bone tumor and was of adoption value. e malignant misdiagnosis rate and malignant missing report rate of MSCT + MRI in distinguishing benign and malignant bone lesions were notably inferior to those of MSCT and MRI, with remarkable difference (P < 0.05)
It was consistent with the results of Carlbom et al [17], indicating that MSCT combined with MRI detection can better improve the misdiagnosis and

Summary

Introduction

With the rapid development of the national economy, there are more and more bone diseases caused by different factors, for example, years of strain, trauma, or bone degeneration and endocrine disorders with age, leading to bone lesions [1,2,3]. Due to the different lesions of the patient’s bones, the clinical manifestations are different. If a fracture occurs after being subjected to direct external force, needle-like pain at the injured site will not be felt. There will be obvious local swelling, positive tenderness, positive percussion pain, and so on, and the joints adjacent to the fracture will have dysfunction [4]. Bone lesions generally include cervical spondylosis, lumbar disc herniation, bone hyperplasia, osteoporosis, osteoarthritis, fractures, and bone tumor.
