PET/MRI helps with pulmonary nodule detection -- to a point

Simultaneous PET/MRI performs better than PET and MRI performed separately for the detection of FDG-avid pulmonary nodules and lesions at least 0.5 cm in size. However, it has problems with non-FDG-avid nodules and smaller lesions, researchers report in the September issue of Radiology.

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.
