Lumbar disc disease
In symptomatic cases the diagnosis should be confirmed by an MRI scan. However, in cases with slight symptoms, a faster and cheaper CT scan (although it is inferior to MRI scan) may be recommended. While a CT scan can show the bony structures in more detail, an MRI scan can better portray soft tissue.
Cognitive genomics
Functional magnetic resonance imaging (fMRI) is a widely available imaging technique that measures changes in blood flow in imaged tissue. It’s commonly used in neurophysiological studies to determine neuron activation. Unlike a standard MRI, fMRI can be used to actively measure subject neuronal activity as the patient performs tasks. This technique isn’t used on conscious non-human primates due to the inability to restrain the primates during imaging. However, fMRI illustrates regional brain activity when performed on primates that performed tasks over an extended period of time and were then anesthetized.
