Prediction of Obstructive CAD from Upright and Supine Stress MPI (image) Society of Nuclear Medicine and Molecular Imaging Share Print E-Mail Caption Short/long axis views, polar maps depicting normalized radiotracer count distribution and perfusion defects (top), and predictions by cTPD and DL (bottom) are shown for two patients with obstructive CAD. (A) In 79-year-old man (85% proximal LAD stenosis) quantified with normal cTPD (per-patient cTPD, 3% and per-vessel cTPD, 1%), DL correctly identified LAD disease. Patient had body mass index of 30 kg/m2 and diabetes and underwent exercise stress MPI. (B) In 62-year-old woman (70% mid LAD stenosis, 95% proximal LCX stenosis, and 80% proximal RCA stenosis) with cTPD abnormal for one vessel only, DL correctly identified triple-vessel disease. Patient had body mass index of 25 kg/m2, dyslipidemia, and family history of cardiac disease and underwent exercise stress MPI. BMI = body mass index.
