Nuclear Cardiology Testing

The early detection of patients with effort induced ischemia is vital as CAD is silent in more than 50% of patients.  This can easily be detected before your patients become symptomatic through Cardiolite Nuclear Stress Myocardial Perfusion Testing.
The Cardiolite Stress test can be performed by exercising patients by treadmill, ergometric bicycle or  with the Lexiscan pharmaceutical agent for the elderly and patients with ambulatory problems. The Lexiscan Cardiolite is performed by inducing sinus tachycardia for a few minutes to the patient.  This patient should not have asthma or a significant respiratory problem if drug-induced tachycardia is to be used.
Indications for performing Nuclear Stress tests on your patients:
  • Patients with angina pectoris or EKG changes of ischemia might qualify for Cardiolite nuclear stress testing, although in some cases these patients should be considered straight candidates for coronary angiography.
  • Patients with more subtle symptoms or who are asymptomatic but can identify with any of the groups listed below, are candidates for Cardiolite stress testing, as coronary artery disease is many times a silent disease and presents itself without symptoms.  Nuclear cardiac testing is the ideal test to evaluate patients with potential silent disease if the patient is in any of the groups listed below.


  • Patients with recent episode angina pectoris
  • Mild, moderate or typical angina pectoris
  • Abnormal electrocardiograms
  • Presence of arrhythmias

Rapid turn-around time

As such, MHS emphasizes a rapid turn-around time that has results back in your referring physician’s office within 48 hours, and same-day callbacks for critical results. We currently have more than 85 diagnostic imaging facilities in Pennsylvania, Eastern Ohio and Northern West Virginia, which can accommodate patients on an as-needed basis.

Setting a new standard for patient comfort and flexibility

Traditional SPECT imaging requires a large patient bed and the patient to move into a confined claustrophobic detector gantry. SPECTpak PLUS allows patients to sit upright and frees them from the confinement of supine imaging. This new design increases patient comfort and as a result, improves image quality.
