Table 1 - PATIENT EXAMS INTERPRETATIONS AND SCORING

PID
MPR
MPR Findings
NM Findings
Cath Findings
DLF
TP
Fixed inf & antero-apical defects. Possible lateral ischemia (unprotected diag area) Fixed inferior defect
Patent SVG beyond 100% RCA. Patent LIMA beyond 90% mid LAD. Circ and Ramus 40% with SVG to Ramus. Large unprotected Diagonal 70%.
GEM
TP
Large anterior & apical perf defect. ? Mid-posterior defect w/ no correlation Post CABG: antero-septal
& apical ischemia & infarction
Pre CABG: 90% LAD, 60% Circ
Post CABG: MI; patient refused cath
HPM
FP
Inf & lateral MPR defects. Note: only 9 min wait time; poor rest bolus response. Note: FP for MPR based
Interpreted as ant ischemia.
?Fixed attenuation defects. Note: FP for NM based on cath
RCA 60% with Patent SVG.
LAD 80-90% with Patent LIMA.
EP
TP
Antero-lateral Ischemia Antero-lateral ischemia Patient refused
VWR
TP
Lateral and infero-lateral defects
Infero-lateral ischemia Severe native CAD. Grafts patent but inf-lat area supplied by sequential distal SVG.
SHT
TP
Mid-inf & posterior-lateral perfusion abnormalities.
Scattered low-MPR areas. Previous infarction.
Antero-apical and basilar lateral fixed defects c/w infarcts No post CABG cath
MM
TP
Infero-posterior ischemia
Infero-posterior ischemia
Occluded RCA w/ retrograde filling via collaterals. OM1 95%.
TP
TN
Normal Fixed posterior defect judged as a FP No cath. Echocardiography normal. MR wall motion and global function measurements normal.
GEH
FP
Inferior-septal MPR ~1.1
Not performed Circumflex stent placed 3 months prior w/ good result. 30% LAD stenosis.
AMF
TN
Normal Interpreted as anterior/apical ischemia, but FP for NM based on cath. Patent stents with 30%-40% dia. Narrowing.
LB
TN
Normal
Normal Patient refused
BP
TN
Normal
Normal Patient refused
DPC
TP
Abnormal MPR in multiple areas

Antero-apical ischemia Stenoses: 90% LAD, 50% Circ, 60%-70% RCA
JAE
TP
Small posterior infarct, non-transmural scarring Normal cardiolite 5/2001 Known CAD with MI & PTCA 1988.
KK
TN
Normal Normal Patient refused

13/15 patients were correctly classified by the MPR imaging. One exam (PID HPM) was scored as a false positive for both MPR and nuclear medicine given the insistence of the performing cardiologist that the catheter angio exam was normal. Other MPR false-positive patient (PID GEH) had a circumflex stent and 30% LAD stenosis, and an MPR region measuring ~1.1.
