Please assess the completion status of the following clinical trial:

Trial Title: Half-Dose Radiopharmaceutical in Wide Beam Reconstruction

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: DIAGNOSTIC
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Patients over the age of 18 years~* Undergoing nuclear stress testing~* History of myocardial infarction, cardiomyopathy, heart failure or prior nuclear studies with resting perfusion defects~Exclusion Criteria:~* Unwilling or unable to undergo an additional resting SPECT acquisition~* Clinical contraindications to nuclear stress testing including acute myocardial infarction~  * For patients undergoing exercise treadmill stress testing:~* Left bundle branch block or artificial ventricular pacemaker~  * For patients undergoing regadenoson (Lexiscan) stress testing:~* Moderate to severe chronic obstructive pulmonary disease or asthma, second- or third degree atrioventricular block or sinus node disease (unless patients have a functioning artificial pacemaker), known hypersensitivity to aminophylline or adenosine~* Inability to give informed consent

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Half-dose radiotracer administration (Type: EXPERIMENTAL): For this study, researchers would like to administer half of the radiotracer, obtain resting images, administer the remainder of the radiotracer and obtain a second set of resting images. Subjects will be given the same amount of radioactive material that would normally be given for this test; however, it will be administered in two ½ doses.

Based on this trial design, predict the completion outcome and termination type (if applicable).
