CIS uses state of the art, dual-screen Cardius 2XPO Camera for optimal quality. CIS offers turn-key mobile imaging packages custom tailored to your practice. You tell us how often you want to run and you only pay for the patients to show up for the test. If your office does not have a treadmill, we use Pharmaceutical stress agents. The CIS turn-key package includes a Nuclear Medicine Technologist, an experienced Certified Cardiographic Technician (all CIS CCTs are certified Paramedics), a mobile dual-head camera, isotopes, medical supplies, and over readers (for an additional fee). We offer reliable and patient-friendly service and are available across southern California. our hours are flexible and our expert teams are conscientious of your time and space. The camera fits easily into a 7′ x 9′ room and our service takes three to five hours to complete (time estimate based on 4-14 patients).
