Unlocking the potential of imaging in Alzheimer’s disease care

In the U.S., Alzheimer's disease cases are projected to rise to nearly 13 million, making effective imaging even more crucial for early identification and effective monitoring and treatment of the condition.

Can ictal SPECT make a comeback in epilepsy patients?

A feasibility study could revive interest in SPECT seizure imaging to help neurosurgeons guide brain surgery in epilepsy patients.

January 16, 2024

Schematic of triggered ictal SPECT and data processing. (A) Previously screened and selected sEEG bipolar contact is stimulated to trigger patient-typical seizure. Directly after seizure onset, confirmed through sEEG signals and semiology, systemic bolus of radiotracer (Tc-99m HMPAO) is administered. Planned SPECT is acquired within less than one hour. (B) Raw data processing from left to right (dataset from participant three as example). Postimplantation CT and preimplantation T1-weighted MRI are coregistered for sEEG lead localization. Raw SPECT images are coregistered to T1-weighted MRI sequence. SPECT deviation map is computed and anatomically colocalized with sEEG signals. Image courtesy of the Journal of Nuclear Medicine.

Enlarged perivascular spaces in infant brains linked to autism risk

By Kate Madden Yee

Infants with enlarged perivascular spaces have a more than two-fold greater chance of developing autism compared to infants with normal-sized perivascular spaces.
