Precisión de la tomografía de 64 cortes en el diagnóstico de estenosis coronaria significativa

invasive coronariography (ic) is the reference pattern for the study of coronary arteries. it has been stated that multiple slice computed tomography (msct) may avoid ic. 62 patients, 50 of whom were males, with mean age 56 ± 8, were studied to evaluate the diagnostic accuracy of the 64-slice msct in the detection of significant coronary stenoses (scs), comparing it with ic. ic was performed due to the presence of scs or persistence of the symptoms. sensitivity (s), specificity (e), positive predictive value (ppv), negative predictive value (npv) and predictive accuracy (pa) were determined by patients and arteries. s, e, ppv, npv and pa were 96.4; 91.2; 87; 96.8 and 93.5 % per patient, respectively; whereas they were 95.7; 97; 88.2; 98.9 and 96.7 % by artery, respectively. it was concluded that msct may replace ic in selected patients.
