Diagnostic Efficacy of CT and MRI with Biopsy in case of Brain Tumours
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 12
Abstract
Background: Magnetic resonance imaging (MRI) has emerged as the primary diagnostic modality for the diagnosis of brain tumours. Brainstem lesions are sometimes treated on clinical and radiological grounds and it had even been argued that biopsy is not warranted in many of these lesions. Hence; we planned the present study to assess 50 brain biopsies and compare their diagnostic yield of different biopsy procures. Materials & methods: The present study included assessment of 50 brain biopsies for comparing their diagnostic yield of different biopsy procures. A total of 50 cases of intra-axial brain mass lesions, with the help of CT and/ or MRI, underwent brain biopsy procedure. Out of all the 50 biopsies included, 30 were frame based CT guided stereotactic, 12 were ultrasound guided and remaining 8 were frameless image guided stereotactic brain biopsies. All the results obtained were compiled on SPSS software. Results: Out of total 50 biopsies received, 30 were frame based biopsy, 12 were ultrasound guided and 8 were frameless image guided biopsy. Diagnostic accuracy of frame based biopsy was 83.3 % while diagnostic accuracy of Ultrasound guided biopsy and Frameless image guided biopsy were 83.3% and 87.5% respectively. Conclusion: Frameless image-guided stereotactic biopsy yielded highest diagnostic accuracy among all other diagnostic biopsy modalities.
