CT reveals cardioembolic stroke that echo misses
By Eric Barnes
Echocardiography may be the de facto gold standard for cardiac evaluation of patients suspected of having cardioembolic stroke, but it isn't necessarily the best modality. A new study from Saudi Arabia used CT to discover several thrombi that echo had missed, along with other conditions.

Chest pain patients do well after ultralow-dose SPECT
By Wayne Forrest
Patients with chest pain who underwent SPECT myocardial perfusion imaging with an ultralow-radiation-dose gamma camera had no major cardiac events a year later. The research, published in the April issue of the Journal of Nuclear Medicine, indicates that MPI radiation dose can be slashed without adverse clinical impact.
