A new myocardial perfusion scintigraphy stress protocol combining dipyridamole-dobutamine-atropine.

Background: Pharmacological stress is often used, and the drugs most frequently utilized are dipyridamole (Dip) and dobutamine (Dob). We aimed to evaluate the safety and the results obtained with a new protocol associating Dip, Dob, and atropine, compared with the Dip protocol.

Methods: Thirty-two patients underwent rest Tl/Dip stress Tc-sestamibi myocardial perfusion tomography on the same day.

[Procedural memory and brain SPECT: blood flow evaluation in the cerebellum and pre-frontal cortex during a visuo-motor task].

The objective of the present study was to evaluate the cerebral blood flow in the cerebellar (4 sub-regions) and pre-frontal cortex, when subjects were in rest and during a motor task performance. The sample consisted of 8 healthy subjects, male or female, between 23 and 36 of age. The visuo-motor task - implicit memory - requires the subjects to navigate and swerve a graphic submarine from missiles that run on the screen.
