Computed Tomography Perfusion Analysis for Stroke

Computed tomography angiography examinations were performed using a second-generation dual-source computed tomography scanner (SOMATOM Definition Flash, Siemens Healthcare, Forchheim, Germany). Perfusion data sets were postprocessed on a Siemens Multimodality Workplace Workstation (Siemens Medical, Erlangen, Germany), yielding mean transit time (MTT), cerebral blood volume (CBV), cerebral blood flow (CBF), and time to peak (TTP) maps. Other CTP parameters^{[24 (link)–27 (link)]} were evaluated and defined as follows to test for association with the mRS score:

Difference of mean transit time (dMTT): (Absolute value of the ipsilateral MTT) − (contralateral MTT of each patient)

rCBV: CBV ratio ([ipsilateral CBV]/[contralateral CBV])

CBV index: ([Ipsilateral CBV] − [contralateral CBV])/(contralateral CBV)

rCBF: CBF ratio ([ipsilateral CBF]/[contralateral CBF])

CBF index: ([Ipsilateral CBF] − [contralateral CBF])/(contralateral CBF)

TTP index: ([Ipsilateral TTP] − [contralateral TTP])/(contralateral TTP)

rMTT: MTT ratio ([ipsilateral MTT]/[contralateral MTT])

Dual-Source CT Perfusion Analysis for Cerebrovascular Assessment

Check if the same lab product or an alternative is used in the 5 most similar protocols

CTA examinations were performed using a second-generation dual-source CT scanner (SOMATOM Definition Flash, Siemens Healthcare, Forchheim, Germany). Perfusion data sets were postprocessed using a Siemens Multimodality Workplace Workstation (Siemens Medical, Erlangen, Germany), which calculated mean transit time (MTT), cerebral blood volume (CBV), cerebral blood flow (CBF), and time to peak (TTP). The arterial input and venous outflow curves were analyzed to ensure data set completeness. The CTP parameters are defined as follows: (1) dMTT: ipsilateral MTT—contralateral MTT. (2) MTT ratio: ipsilateral MTT/contralateral MTT. (3) MTT index: (ipsilateral MTT—contralateral MTT)/contralateral MTT. (4) dCBV: ipsilateral CBV—contralateral CBV. (5) CBV ratio: ipsilateral CBV/contralateral CBV. (6) CBV index: (ipsilateral CBV—contralateral CBV)/contralateral CBV. (7) dCBF: ipsilateral CBF—contralateral CBF. (8) CBF ratio: ipsilateral CBF/contralateral CBF. (9) CBF index: (ipsilateral CBF—contralateral CBF)/contralateral CBF. (10) dTTP: ipsilateral TTP—contralateral TTP. (11) TTP ratio: ipsilateral TTP/contralateral TTP. (12) TTP index: (ipsilateral TTP—contralateral TTP)/contralateral TTP. CTA/P imaging was performed using a second-generation dual source CT scanner (SOMATOM Definition Flash, Siemens Healthcare, Forchheim, Germany).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
