Learning objectives: 1. Viewers will learn a systematic imaging approach to cases of basal ganglia pathologies. 2. Specific key imaging features of common and uncommon basal ganglia lesions will be highlighted.   3. Utilisation of advanced MR sequences like susceptibility, perfusion, Diffusion weighted imagi[...]

Background: Many systemic and focal diseases may present as basal ganglia abnormalities. We present a spectrum of MRI of basal ganglia pathologies, also highlighting the utility of advanced imaging sequences like susceptibility, perfusion, ADC values, CISS and MRS which help in the diagnosis. Common and uncommo[...]

Findings and procedure details: A total of 100 MRI brain studies with basal ganglia pathologies with advanced imaging techniques were retrospectively evaluated. Out of these, 60 studies with clinical, histopathological and biochemical correlation were included in our study   Various basal ganglia pathologies are grouped and [...]

Conclusion: The radiologists and clinicians need to identify the differentials on routine MRI sequences and with clinical correlation utilise the advanced sequences to establish a definitive diagnosis. They should also be aware of the sequence of choice in each pathologies to arrive at the right diagnosis which[...]
