High-Resolution SPECT Cuts Imaging Time in Half

The CardiArc, a SPECT imaging device will reportedly give physicians sharper images of blood flow and function of their patient’s hearts — in half the time previously required.

Offered by CardiArc Ltd., the patented, technology for cardiac single photon emission computed tomography (SPECT) reportedly has twice the resolution of existing devices. The system is as small as an executive chair, runs on 110 Volts AC and fits easily in a 6-by-7 foot exam room without remodeling, said the company.

The device reportedly has no visible moving parts and uses solid-state CZT technology (cadmium zinc telluride). Patients sit upright, without rotating or holding arms over their heads. Scan times are fast, ranging from two to six minutes at physician discretion.
