In all the cases analyzed, the area of pathologic perfusion was larger, than the tumor size seen in contrast-enhanced CT (p<0.05). Moreover, the tumor area in PCT had better defined margins and correlated well with intraoperative findings.Conclusions: PCT provides valuable information about ...
milrinone was more frequently administered (80 vs 54%,p<0.001) and associated with superior hemodynamics. The present study from a large cohort of aSAH patients suggests, for one part, the interest of CTP in early diagnosis of vasospasm and DCI, and for the other the efficacy of CT perfusio...
In cases of ongoing ischemia, computed tomography perfusion (CTP) can be a useful adjunct to non-contrast CT and computed tomography angiography (CTA) for evaluation of tissue at risk [ 1 , 2 ]. Traditionally, obtaining a CTP study has required transporting the patient from the ER or ...
在设备许可的情况下,在保证扫描成功且图像质量达到诊断要求水平时,推荐使用前瞻性心电门控、迭代重建和低管电压技术,尽可能降低辐射剂量。根据临床适应证确定需行CT心肌灌注成像(CT myocardial perfusion,CTP)检查者,可参考《动态CT心肌灌注成像技术操作...
The V2 acquisition time and contrast enhancement determined by the prospective protocol simulation were then compared with the actual peak time and the actual peak enhancement using paired sample t-testing (SPSS, version 22, IBM, Armonk, NY). Finally, simulated prospective two-volume perfusion ...

Peritoneal hyperthermic perfusion has been used to concentrate drugs locally, and this can augment the antitumor response in retroperitoneal metastatic lymph nodes [11]. However, it is difficult to obtain better results for relatively large retroperitoneal metastatic lymph nodes. In recent years, new ...
A three-phase bone scan is typically performed with increased perfusion, vascularity and uptake considered as highly diagnostic for infection. The combination of SPECT and CT allows for comprehensive assessment of the prosthesis incorporating the metabolic changes with the anatomical abnormalities to better...
Thirty one consecutive patients strongly suspected of severe Middle Cerebral Artery AIS presenting less than 6 h after onset of symptoms or with unknown time of onset of symptoms underwent a standardized CT protocol in spectral mode including Non Contrast CT, mCTA, and Perfusion CT (CTP) on a ...
Supplementary SectionS2of the Supplementary Information demonstrates this for one sample case where the perfusion territories were computed based on the entire lumen for each artery, which is a common alternative to the method used here based on just the coronary outlets....
