Determination of the first site of spine involvement in vertebral column metastases with MRI

Abstract

Due to this point and the importance of early detection of vertebral metastasis to determine the treatment stages and future examinations of the patient, there are no similar studies with the help of MRI and due to the fact that this method is available in many parts of the country. It is performed to accurately determine the areas involved in the vertebrae during metastasis. Materials and Methods: This is a descriptive observational study that was retrospectively performed on 70 patients and recorded patient information from the clinical record. Patients with breast, lung, kidney, and other cancers who underwent a positive bone scan were included in the study. Demographic information of patients including age, gender, status of underlying diseases and duration of infection were extracted and recorded from patients' clinical records. To determine the exact type of lesion as vertebral metastasis, they are examined by MRI. All scans were performed by MRI and 1/5 T. In this study, only individual metastases were considered and the first site of involvement was investigated. Results: The mean age of patients was 57.92±10.94 years and most patients were female (55.7%). The most common underlying disease in the studied patients was hypertension (20%). Also, the most common type of cancer with bone metastasis was related to Brest cancer (48.6%). The most common metastatic involvement was related to the thoracic vertebrae (T9 vertebrae with a frequency of 11.4%) and then the lumbar vertebrae (L3 vertebrae with a frequency of 10%). In general, the thoracic vertebrae had the most involvement (51.45%). Also, the most common site of involvement in the vertebrae was related to the body vertebrae (78.57%).
