NeuroLogica Corporation has received the 510(k) clearance from the FDA for the SPECT (single photon emission computed tomograph). The inSPira HD is a mobile system that runs on batteries and can be moved around hospital wards if necessary. Image quality of inSPira HD is close to that of PET with the resulting reconstructed spatial resolution as high as 3.0mm. inSPira HD is capable of imaging all available neuro radiotracers offering a broad range of clinical applications including Epilepsy, Parkinson’s, Stroke and Alzheimer’s.

X-ray imaging is unable to differentiate between certain types of cells, since the X-ray light is strong and passes through the soft tissue. Scattering substances such as iodine can be used to increase the resolution of the X-ray image. However, these can only be used where the blood flow is high. Lon Wilson from the Rice University, Houston, has proposed the use of carbon nanotubes that can be filled with iodine solution and coated with special proteins. This would allow the X-ray machine to target the desired types of cells.
