Background: Tumour assessment by magnetic resonance imaging (MRI) helps to accurately measure and estimate tumours before breast-conserving surgery.
Objective: The study aims to describe the imaging characteristics of 1.5 Tesla MRI in breast cancer diagnosis and evaluate the value of MRI in breast-conserving surgery.
Methods: A cross-sectional descriptive study was conducted on 99 patients newly diagnosed with breast cancer who were indicated for breast-conserving surgery at Tan Trieu K Hospital from July 2020 to August 2021. All participants underwent assessing characteristics of breast tumours by 1.5 Tesla MRI. The data were analysed using SPSS version 20.0, with descriptive statistics applied to summarize the study variables.
Results: The study showed that the characteristics of breast tumours determined by 1.5 Tesla MRI, most patients had low (33.4%) and moderate (31.3%) contrast enhancement, and the group of tumours with multiple spread locations had the highest rate of histological grade III (71.4%). The majority of tumours had irregular shapes and margins (53.6% and 60.7%), and most tumours demonstrated early enhancement (88.9%). In addition, based on MRI results, 12 (12.1%) patients had their surgical options changed, and 6 cases benefited from these decisions.
Conclusion: 1.5 Tesla MRI images help to accurately diagnose the morphology, tumour location, and contrast agent absorption level of breast cancer, thereby resulting a modification of the surgical plan for 12 patients. Therefore, 1.5 Tesla MRI needs to be performed on a large scale with patients indicated for conservative surgery in order to design the most appropriate and effective treatment regimen.
