Scoring GE AW software is a 3D advanced imaging system of GE healthcare. It performs advanced visualization of CT and MRI advanced modality. GE AW 3D was used to perform volumetric analysis and quantify vascular invasion on the CT images of 22 study participants. This software has the ability to highlight the specifically identified vessels attached to a tumor before treatment (known as the “Baseline Vessel”) and after treatment. Such vessels were then categorized as having a “Major” or “Minor” role in tumor development. Changes in the number of vessels involved and tumor volume demonstrated disease progression or regression.
Regions of interest were identified between the arterial and venous phases, which were automatically defined and manually edited for volumetric tumor quantification. Figure 1 depicts the images that were used to assess tumor growth and vessel involvement. 3D tumor volumetric assessments Spain phone number list were performed to assess treatment response linked directly with tumor perfusion. In a few cases, we could not perform the 3D volumetric due to the stent, which did not allow us to differentiate the margin due to density issues. We decided not to perform the volumetric quantification in those cases due to the concern for accuracy because every fraction of volume is significant in this study for tumor response.
Scans were taken prior to and after the treatment regimen, which were analyzed in the arterial (a, d) and venous phases (b, e). A 3D-generated image of the patient's baseline tumor and final tumor size were created to visualize perfusion differences and determine tumor volume (c, f). The patient had a pre-treated tumor volume of 86 cc and a post-treated tumor volume of 31 cc, which indicates the regression of the tumor after therapy, but surgical candidacy is still questionable. Marley equation The Marley equation defined by Rahmanuddin et al. (2021) describes the difference between arterial and venous perfusion to predict tumor aggressiveness.
