All images were acquired using a Siemens Symbia T2 dual-head SPECT/CT scanner, following standard protocols outlined in the European Association of Nuclear Medicine (EANM) guidelines. The imaging protocol consisted of a two-stage acquisition approach, rest and stress. For the rest phase, patients received 15–20 mCi (555–740 mBerkel) of ^99mTc-methoxyisobutylisonitrile (MIBI), with doses adjusted based on body mass index. To ensure adequate distribution of the radiopharmaceutical in the myocardium, the imaging phase began after a 45-min uptake period. The stress phase was performed using treadmill exercise (Bruce protocol) or a pharmacological stress test (dipyridamole injection 0.56 mg/kg over 4 min). At the peak of stress, 20-25 mCi (740-925 megabarkels) of ^99mTc-MIBI was administered intravenously and imaging began 15-45 minutes after injection. The data are bi-labeled, with and without coronary artery disease (CAD), with 54 images with CAD and 90 images without CAD. Also, the clinical data of the patientswere stored in an Excel file.
