PET takes a ride on the astral plane
PET imaging with oxygen-15-labeled water showed specific brain activation related to an out-of-body experience of a 63-year-old patient stimulated with electrodes to suppress tinnitus.
Dr. Dirk de Ridder and colleagues at the University Hospital at Antwerp and the University Hospital Leuven in Belgium reported significantly increased activity at the temporoparietal junction on the right side.
The man's disembodied feeling was accompanied by activity in a cortical region associated with multisensory integration and another region associated with self-perception (NEJM 2007;357:1829-1833).
The patient's perception of disembodiment always involved a location about 50 cm behind his body and off to the left, and without the impression of seeing himself from a distance.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
Systematic Review: PET/MRI May be More Advantageous than PET/CT in Cancer Imaging
July 18th 2024While PET/MRI and PET/CT had comparable sensitivity for patient-level regional nodal metastases and lesion-level recurrence, the authors of a systematic review noted that PET/MRI had significantly higher accuracy in breast cancer and colorectal cancer staging.
