摘要	The purpose of the current study was to evaluate the advantages of contrast-enhanced transcranial doppler (c-TCD) conducted via two-channel mode, compared to single-channel mode. The parallel test method of diagnostic testing was adopted. Two-channel c-TCD was conducted and interpreted via three different methods, comparing differences between the effects of conducting c-TCD via two-channel mode and single-channel (either left or right) mode. Conditions were set so that the appearance of microbubble signals in either channel was the golden diagnostic criteria for right to left shunts. Diagnostic sensitivity of single channel c-TCD mode was evaluated. Diagnostic consistencies and positive rates were compared between single-channel and two-channel modes. A total of 242 cases were enrolled in this study. Diagnostic sensitivities of left and right single channel mode were 77.46% and 76.06%, respectively, under a resting state. They were 95.31% and 96.88%, respectively, after the Valsalva maneuver (VM). Under a resting state, diagnostic consistencies were general between two-channel and left channel modes and between two-channel and right channel modes (Kappa value = 0.740, 0.724, respectively; P < 0.001). After VM, both diagnostic consistencies were good (Kappa value = 0.894, 0.928, repetitively; P < 0.001). After VM, although diagnostic consistencies were good, positive rates of two-channel c-TCD mode were significantly higher than those in both left and right single-channel c-TCD modes (79.34% vs. 75.62%, P = 0.004; 79.34% vs. 76.86%, P = 0.031; respectively). Two channel c-TCD mode had higher positive rates than single-channel mode, especially in patients with small right to left shunts or poor coordination of VM.
